Seafood and Avocado Salad Recipe, Spotlight on Dill and Herb Scissors, Could Your Diet Be Increasing Your Anxiety? And Knee Arthritis, Exercise, and Your Subconscious

Are you usually underwhelmed when you buy premade seafood salad? Making your own is not only tastier but also less expensive. And prepared with healthful ingredients, like extra virgin olive oil and avocado instead of questionable fillers, it’s also good for you. The distinction between healthy and unhealthy fats is made clear in the first study that I’m sharing—you’ll see why a diet of saturated fat is linked to anxiety. Turning to fitness, many people with knee arthritis don’t heed their doctor’s advice to exercise…here are the results of a study that found they may have a subconscious resistance to activity.

Seafood and Avocado Salad

  • Seafood Avocado Salad Seafood and Avocado Salad

    Pick your own culinary adventure with the seafood you choose for this dish—succulent lobster meat, crabmeat, shrimp, calamari rings, or any combination. I love to serve the seafood in avocado halves, but if you prefer a handheld meal, add avocado cubes to the mix and sandwich it between ciabatta slices that have been lightly toasted or grilled and drizzled with olive oil.

    Ingredients

    • 1 pound cooked shellfish
    • 8 ounces cherry tomatoes, halved
    • 1 cucumber, diced
    • 1/2 cup chopped red onion
    • 1/4 cup extra virgin olive oil
    • 2 tablespoons balsamic vinegar, plus more to taste
    • 1 tablespoon chopped fresh dill
    • Coarse sea salt to taste
    • Freshly ground black pepper to taste
    • 3 ripe avocados, halved and pitted 

    Directions

    In a large bowl, mix the shellfish, tomatoes, cucumber, red onion, olive oil, vinegar, and dill. Taste and season as desired with salt and pepper. Divide the salad among the avocado halves, mounding it high (a large ice cream scoop works well).

Dill

Fresh dill is a delicate yet delicious addition to many types of salads, including various versions of potato salad, and can be used for enhancing eggs, dishes with smoked or fresh salmon, and dressings. Because of its feathery shoots, dill makes a showy garnish. It’s best used in cold dishes; when using it during cooking, add it at the very last minute or right after you’ve removed the food from the heat. 

It’s easy to grow dill in your herb garden (it often reseeds itself) or plant it in a window box so you can regularly reach for it. If you buy a bunch from the store or farmers’ market, place the stems in a tall glass of water, cover the tops, and refrigerate to increase shelf life. As with other fresh herbs, it can be puréed with extra virgin olive oil and frozen in an ice cube tray for future use (bag the cubes as soon as they become solid). Dill is sold dried as dill weed, with a very mild flavor that actually improves when heated.

Could Your Diet Be Increasing Your Anxiety?

When stressed out, many of us turn to junk food for solace. But new University of Colorado Boulder research suggests this strategy may backfire. The study found that, in rats, a high-fat diet disrupts gut bacteria, alters behavior and, through the complex pathway that connects the gut to the brain, influences brain chemicals in ways that fuel anxiety. It’s important to note that the researchers are not talking about healthy fats like those found in fish, olive oil, nuts, and seeds—these are considered anti-inflammatory and good for the brain.

“Everyone knows that [high-fat junk foods] are not healthy foods, but we tend to think about them strictly in terms of a little weight gain,” said lead author Christopher Lowry, PhD, a professor of integrative physiology at CU Boulder. “If you understand that they also impact your brain in a way that can promote anxiety, that makes the stakes even higher.”

Dr. Lowry’s team divided adolescent rats into two groups: Half got a standard diet of about 11% fat for nine weeks while the others got a high-fat diet of 45% fat, consisting mostly of saturated fat from animal products. (The typical American diet is about 36% fat, according to the Centers for Disease Control and Prevention.) Throughout the study, the researchers collected fecal samples and assessed the animals’ microbiome, or gut bacteria. After nine weeks, the animals underwent behavioral tests.

Importantly, the researchers stressed that not all fats are bad, and that healthy fats like those found in fish, olive oil, nuts, and seeds can be anti-inflammatory and good for the brain.

When compared to the control group, the group eating a high-fat diet, not surprisingly, gained weight. But the animals also showed significantly lower diversity of gut bacteria. Generally speaking, more bacterial diversity is associated with better health, Dr. Lowry explained. These mice hosted far more of a category of bacteria called firmicutes and less of a category called bacteroidetes. A higher firmicutes-to-bacteroidetes ratio has been associated with the typical industrialized diet and obesity.

The high-fat diet group also showed higher expression of three genes—tph2, htr1a, and slc6a4—involved in the production and signaling of the neurotransmitter serotonin, particularly in a region of the brainstem called cDRD and associated with stress and anxiety.

While serotonin is often billed as a feel-good brain chemical, Dr. Lowry pointed out that certain subsets of serotonin neurons can, when activated, prompt anxiety-like responses in animals. In fact, heightened expression of tph2, or tryptophan hydroxylase, in the cDRD has been linked to mood disorders and suicide risk in people.

“To think that just a high-fat diet could alter expression of these genes in the brain is extraordinary,” said Dr. Lowry. “The high-fat group essentially had the molecular signature of a high anxiety state in their brain.” He suspects that an unhealthy microbiome compromises the gut lining, enabling bacteria to slip into the body’s circulation and communicate with the brain via the vagus nerve, an important pathway from the gastrointestinal tract to the brain.

“If you think about human evolution, it makes sense,” Dr. Lowry explained. “We are hardwired to really notice things that make us sick so we can avoid those things in the future.” 

His advice: Eat as many different kinds of fruits and vegetables as possible, add fermented foods to your diet to support a healthy microbiome, and lay off the pizza and fries. Also, if you do have a hamburger, add a slice of avocado. Some research shows that good fats can counteract some of the effects of bad fats.

Knee Arthritis, Exercise, and Your Subconscious

Yoga poses for knee exercise

Knee osteoarthritis (OA) is a common cause of pain and joint stiffness. And while physical activity is known to ease symptoms, only one in 10 people regularly exercises. Understanding what contributes to this inactivity is the focus of a study from the University of South Australia (UniSA) in Adelaide, where researchers found that people with knee OA unconsciously believe that activity may be dangerous to their condition, despite medical advice telling them otherwise.

The study found that of those surveyed, 69% of people with knee pain had stronger implicit (or unconscious) beliefs that exercise was dangerous than did the average person without pain. This highlights not only the conflicted nature of pain and exercise but also the fact that what people say and what people think, deep down, may be entirely different things.

Lead researcher and UniSA PhD candidate Brian Pulling said the research provides valuable insights for helping people with knee arthritis. “Research shows that physical activity is good for people with knee OA, but most people with this condition do not move enough to support joint or general health,” Pulling said. “To understand why people with OA might not be active, research studies typically use questionnaires to assess fear of moving. But unfortunately, questionnaires are limited—what we feel deep down (and how our system naturally reacts to something that is threatening) may be different than what we report. And we still know that many people are avoiding exercise, so we wanted to know why.”

To do so, the researchers developed a tool called the Implicit Association Test that can detect and evaluate people’s implicit beliefs about exercise, meaning whether they unconsciously think activity is dangerous for their condition. The test presents a series of words and images which a participant must quickly associate with being either safe or dangerous. It intentionally promotes instant responses to avoid deliberation and other influencing factors (such as responding how they think they should respond).

“We found that even among those who said they were not fearful about exercise, they held unconscious beliefs that movement was dangerous,” Pulling said. “Our research shows that people have complicated beliefs about exercise, and that they sometimes say one thing if asked directly yet hold a completely different implicit belief. This research suggests that to fully understand how someone feels about an activity, we must go beyond just asking directly, because their implicit beliefs can sometimes be a better predictor of actual behavior than what people report. That’s where our tool is useful.”

The tool has the potential to identify a group of people who may have challenges to increasing their activity levels and undertaking exercise. Added Tasha Stanton, PhD, Associate Professor in clinical pain neuroscience and co-Director and Osteoarthritis Research Theme Lead at IIMPACT in Health at UniSA, “Having access to more accurate and insightful information will help health professionals better support their patients to engage with activity and exercise. It may also open opportunities for pain science education, exposure-based therapy, or cognitive functional therapy…things that would not usually be considered for someone who said that they were not scared to exercise.”

Orange-Raspberry Muffins Recipe, Spotlight on Almond Flour, Juicing Fruit, The Benefits of Limiting Processed and Red Meats, and High Intensity Interval Training (HIIT)

Packaged gluten-free baked goods are often tasteless, not to mention filled with additives and other unhealthy ingredients. In just a few minutes, you can bake your own delicious muffins that are so tasty that they won’t provoke eye rolls from gluten lovers. While gluten should be avoided only by those with a sensitivity or celiac disease, a recent study found that everyone can benefit from eating fewer processed and red meats—the health benefits are astounding. Then read about a newly discovered benefit of high-intensity interval training (HIIT).

Orange-Raspberry Muffins

  • Orange raspberry muffins Orange-Raspberry Muffins

    The combination of olive oil and almond flour creates a tender crumb that rivals any flour-based batter and a muffin that’s infinitely more nutritious. I like to use “tulip-shaped” cupcake liners because you can fill them right up to the level of your baking tin for very tall muffins. Also, topping the batter with berries after filling the liners helps keep the fruit from falling to the bottom. 

    Ingredients

    • 3 cups almond flour
    • 1-1/2 teaspoons baking powder
    • 1/2 teaspoon fine sea salt
    • 3/4 cup extra-virgin olive oil
    • 1/2 cup sugar, divided use 
    • Freshly grated zest of 1 large orange
    • 1/2 cup fresh orange juice
    • 6 eggs, separated
    • 1 tablespoon vanilla paste
    • 1 cup raspberries

    Directions

    Step 1

    Preheat your oven to 350°F. Place tulip-shaped cupcake liners in the cups of a 12-muffin tin; set aside.

    Step 2

    In a large bowl, sift together the almond flour, baking powder, and salt. In a separate bowl, whisk together the olive oil, 1/4 cup sugar, orange zest and juice, egg yolks, and vanilla. Fold in the flour mixture.

    Step 3

    In a very large bowl or the bowl of a stand mixer, beat the egg whites on a low speed to break them up, about a minute. Once they start to foam, increase the speed to high and add the remaining sugar. Whip until the whites form stiff peaks, then use a large spatula to gently fold them into the almond flour mixture in 3 or 4 batches, rotating your mixing bowl as you move your spatula from the center out to the sides. Don’t overmix to avoid deflating the batter—a few streaks of whites are OK.

    Step 4

    Use a large ice cream scoop to fill the paper liners up to the level of your baking tin. Top with equal amounts of berries. Bake the muffins for 30 to 40 minutes, until the tip of a sharp knife comes out clean. Serve warm or at room temperature.

    Yields 12 muffins

Almond Flour

Almond flour, like other nut flours, is wonderful for baking, whether you’re making muffins, a cake like a dacquoise or torte, cookies, or even pie shells. You can grind your own from fresh almonds or buy it by the bag. Some brands are made of blanched almonds, but those made with the almond skins offer even more nutrients. Like almonds themselves, almond flour is naturally rich in vitamin E and other antioxidants, manganese, and magnesium, with a healthy dose of protein and fiber. To keep it fresh, store it in the fridge or freezer.

Juicer or Hand Squeezer?

When a recipe calls for any type of citrus juice, fresh-squeezed is a must. The question then becomes whether to use a hand press or an electric citrus juicer. The answer depends on how much juice you’ll be making. 

For a few tablespoons up to a cup, a metal hand press (look for one with ergonomic handles) will work well with minimal strain on your hands—it does take effort to squeeze its handles together, and you might need different sizes for juicing limes, lemons, and oranges effectively. For juicing large quantities, it pays to have an electric juicer for ease and speed; this countertop appliance can handle all sizes of citrus and can be stored in a cabinet when not needed. There are also large, commercial-grade manual juicers that sit on a flat surface and that you operate by pushing down on a lever to extract the juice, but these tend to take up a lot of counter space.  

For Your Best Health: The Benefits of Limiting Processed and Red Meats

The Benefits of Limiting Processed and Red Meats

While many studies have identified links between frequent consumption of processed meat and chronic disease, few have evaluated the impact on multiple health outcomes. Some previous research also suggested that unprocessed red meat may contribute to chronic disease risk, but evidence has been limited.

Now, a team from the University of Edinburgh’s Global Academy of Agriculture and Food Systems, together with researchers from the University of North Carolina, Chapel Hill, has used data from a Centers for Disease Control and Prevention national health survey to create a simulated, representative sample of the US adult population—called a microsimulation—in order to estimate how changes in meat consumption affect adults’ risk of diabetes, cardiovascular disease, colorectal cancer, and death. The effects were evaluated in the overall population and separately based on age, sex, household income, and ethnicity.

This microsimulation is the first to estimate the effects of reducing processed meat and unprocessed red meat consumption, from between 5 percent and 100 percent, on multiple health outcomes in the US. They found that cutting processed meat intake by 30 percent (the equivalent of around 10 slices of bacon a week) would prevent more than 350,000 cases of diabetes and lead to 92,500 fewer cardiovascular disease cases and 53,300 fewer colorectal cancer cases over a decade.

The researchers also analyzed the impacts of reducing unprocessed red meat intake alone and cutting consumption of both processed meat and unprocessed red meat. Cutting unprocessed red meat intake alone by 30 percent, which would mean eating around one less quarter-pound beef burger a week, resulted in more than 732,000 fewer diabetes cases, 291,500 fewer cardiovascular disease cases, and 32,200 fewer colorectal cancer cases. Reducing consumption of both by 30 percent resulted in 1,073,400 fewer diabetes cases, 382,400 fewer cardiovascular disease cases, and 84,400 fewer colorectal cancer cases.

The finding that more disease cases were prevented by reducing unprocessed red meat than by reducing processed meat is partly due to the average daily intake of unprocessed red meat being higher than that of processed meat, at 47 grams a day versus 29 grams a day, respectively. As less is known about the effect of eating unprocessed red meat on chronic disease risk, the team said these estimates should be interpreted with caution and that more research is needed.

Lindsay Jaacks, PhD, professor, Personal Chair of Global Health and Nutrition at the University of Edinburgh, and one of the authors of the study, said, “Cutting consumption of meat has been recommended by national and international organizations to reduce greenhouse gas emissions, including by the Climate Change Committee here in the UK and the United Nations Intergovernmental Panel on Climate Change. Our research finds that these changes in diets could also have significant health benefits in the US, and so this is a clear win-win for people and planet.”

The study, “Estimated effects of reductions in processed meat consumption and unprocessed red meat consumption on occurrences of type 2 diabetes, cardiovascular disease, colorectal cancer, and mortality in the USA: a microsimulation study,” was published in TheLancet Planetary Healthand was funded by the Wellcome Trust.

An Exercise Brain Boost That Can Last for Years

A longitudinal study led by Emeritus Professor Perry Bartlett, PhD, and Daniel Blackmore, PhD, of the University of Queensland’s Queensland Brain Institute found that high-intensity interval exercise improves brain function in healthy older adults for up to five years. The research was published inAging and Disease.

Dr. Bartlett said it is the first controlled study of its kind to show that exercise can not only delay cognitive decline but also boost cognition in healthy older adults. “Six months of high-intensity interval training (HIIT) is enough to flick the switch,” Dr. Bartlett said. “In earlier preclinical work, we discovered exercise can activate stem cells and increase the production of neurons in the hippocampus, improving cognition. In this study, a large cohort of healthy 65- to 85-year-old volunteers joined a six-month exercise program, did biomarker and cognition testing, and had high-resolution brain scans.”

During the study, the researchers assessed the impact of three exercise intensities: low—predominantly motor function, balance, and stretching; medium—brisk walking on a treadmill; and high—four cycles of running on a treadmill at near maximum exertion. Participants exercised three times a week, for between 36 and 45 minutes per session including warmup and cooldown, and under supervision for 6 months. 

Dr. Blackmore said only the high-intensity interval exercise led to cognitive improvement that was retained for up to five years. “On high-resolution MRI scans of that group, we saw structural and connectivity changes in the hippocampus, the area responsible for learning and memory,” he said. “We also found blood biomarkers that changed in correlation to improvements in cognition. Biomarkers can be useful in predicting the effectiveness of the exercise a person is doing.”

Aging is one of the biggest risks for dementia, a condition that affects almost half a million Australians. “If we can change the trajectory of aging and keep people cognitively healthier for longer with a simple intervention like exercise, we can potentially save our community from the enormous personal, economic, and social costs associated with dementia,” Dr. Bartlett said.

With one out of three people aged 85 likely to develop dementia, Dr. Blackmore said, the impact of the research is far-reaching. “Our finding can inform exercise guidelines for older people and further research could assess different types of exercise that could be incorporated. We are now looking at the genetic factors that may regulate a person’s response to exercise to see if we can establish who will and who will not respond to this intervention. The use of biomarkers as a diagnostic tool for exercise also needs further research,” he added. 

Since HIIT has benefits for people of any age, from heart health to a metabolism boost, talk to your doctor or personal trainer about adding it to your exercise regimen.

Rainbow Slaw Recipe, Spotlight on Barley, Ancient Grains to Combat Diabetes, and Exercise + Greenscape = Bliss

There’s everything to love about a no-cook side dish that’s as tasty as it is visually appealing. My twist on traditional coleslaw brings together three different cruciferous veggies—all known for their high-level nutrients—and an olive-oil based dressing that adds in a healthy dose of polyphenols. It also includes barley, a whole grain with surprising health benefits. Finally, take advantage of the warm, sunny days to move your exercise activities to a greenspace—this change of venue can have physical and emotional benefits.

Rainbow Slaw

  • Rainbow coleslaw Rainbow Slaw 

    Move over, mayo! A tangy vinaigrette is a great way to dress a slaw. And what a slaw this is—a colorful feast of fresh veggies enhanced with barley, an ancient grain that’s more versatile than you may think (see “Healthy Ingredient Spotlight” and “For Your Best Health” in this week’s newsletter).

    Ingredients

    • 3/4 cup uncooked hulled barley 
    • 3 tablespoons sherry vinegar
    • 1 tablespoon Dijon mustard
    • 1 tablespoon honey 
    • 1/4 cup chopped shallots
    • 4 tablespoons extra virgin olive oil
    • 1 pound head green cabbage, cored
    • 1/2 pound head red cabbage, cored
    • 1/2 pound Brussels sprouts, trimmed
    • 2 yellow or red bell peppers, stems and ribs removed
    • 1 red onion, trimmed
    • 3 large carrots, scrubbed and peeled, if needed
    • 1/4 cup fresh flat-leaf parsley, finely chopped
    • 1/4 cup fresh dill, finely chopped 
    • Coarse sea salt, to taste
    • Freshly ground black pepper to taste

    Directions

    Step 1

    Prepare the barley according to package directions and set aside to cool. Make the vinaigrette by whisking together the vinegar, mustard, honey, and shallots. Slowly drizzle in the olive oil, whisking until the vinaigrette has emulsified. 

    Step 2

    Grate all the vegetables by hand or machine and toss thoroughly in a very large glass mixing bowl along with the herbs. Add the vinaigrette and toss well again. Taste and add more vinegar, if desired, along with salt and pepper. Serve at room temperature but refrigerate any leftovers.

Barley

If you only know barley from beef barley soup, you’re missing out on so many other ways to enjoy this whole grain—as a side dish with sautéed onions, as a breakfast cereal with fruit, or as a layered parfait with yogurt, to name just a few. A toothsome swap for white rice (which has almost no fiber and few nutrients because it’s refined), barley delivers on fiber, protein, and many vitamins and minerals. It also helps keep blood glucose steady, promotes a healthy gut biome, and fills you up. Though the cooking time is longer, hulled barley retains far more nutrients than pearl barley, so shop for that. Note: Barley does contain gluten, so it’s not for people with celiac disease or gluten sensitivity.

Make a Weekly Barley Batch

Take some time one day a week to make enough barley for four or more servings, so that it’s ready when you are. Though package directions vary, you often need 3 or 4 cups of water per cup of uncooked barley. Keep an eye on it as it cooks, since the water may evaporate before the barley is done. It should retain its shape and be chewy, not mushy.

Ancient Grains Combat Diabetes 

According to the research review “Use of ancient grains for the management of diabetes mellitus: A systematic review and meta-analysis” published in the journal Nutrition, Metabolism and Cardiovascular Diseases, “there has been renewed interest in ancient grain varieties for their possible enhanced health benefits in [diabetes]. Ancient grains represent an important category of ancient cereals that have not undergone human breeding or genetic modification, thus preserving their inherent genetic features. The genetic diversity of these ancient crops not only offers a variety of food options but also represents a valuable genetic heritage to be preserved.” 

The report goes on to detail the phytochemicals in ancient grains, including phytosterols, phenolic compounds like ferulic acid and lignans, flavonoids, and carotenoids, all linked to a variety of health benefits thanks to their antioxidant and anti-inflammatory properties. Among the grains in the many studies the researchers reviewed with positive results are oats, brown rice, millet, buckwheat, and barley. Many are rich in beta-glucan, a type of soluble fiber that has been shown to improve insulin sensitivity.

Separate studies done at the University of Arizona found that the beta-glucan in barley surpassed other grains in terms of cholesterol reduction—it helps flush it out of your body. 

These and other research reports highlight the value of choosing these grains over refined ones—they take longer to cook but are more than worth the effort when it comes to feeling satisfied (they really fill you up!) and to improving heart health by mitigating two of its biggest risk factors: diabetes and high cholesterol.

Exercise + Greenscape = Bliss

We know from past studies that being in nature brings physical and mental health benefits similar to those of physical activity and, of course, we know the benefits of exercise in general. So could exercising in greenspace boost the separate health benefits of each?

To answer this and other questions, Jay Maddock, PhD, Regents Professor with the School of Public Health at Texas A&M University and director of the university-led collaborative Center for Health & Nature, along with Howard Frumkin, MD, DrPH, Hagler Fellow and senior vice president and director of the Land and People Lab, assessed existing evidence regarding physical activity in natural settings and developed strategies for promoting these activities. Their study, published in the American Journal of Lifestyle Medicine, identified several factors that affect how often people visit parks and natural settings, the extent to which they engage in physical activities once there, and the benefits they get from this activity.

Dr. Maddock and Dr. Frumkin found that research suggests exercising in a park or other natural setting is more beneficial than exercising indoors. Because the studies they reviewed focused on short-term outcomes (less than one year), whether these benefits occur over the long term remains to be seen. “Despite this, the research is clear that natural settings could be an effective venue for promoting physical activity,” Dr. Maddock said. “People generally enjoy being outdoors, with parks, trails, and community gardens being the most popular venues.”

What makes the outdoors more enticing? Physical features, like community centers, playgrounds, lighting, and clear signage; natural features, such as a tree canopy and scenic bodies of water; and factors like classes, festivals, a welcoming environment, and a perception of safety, as well as visitors’ strong feeling of connectedness to nature and belief that spending time in these spaces, all contribute.

“Parks and trails are particularly important due to their accessibility and widespread availability, but access varies significantly by geography, and rural areas often have less access to natural spaces because they have more privately held land,” Dr. Maddock said. “For example, nearly 98 percent of Illinois residents live within half a mile of a park, compared to only 29 percent in Mississippi.”

Getting outdoors to take in the countryside is one of my favorite parts of every fresh-pressed olive oil hunt. Here I am with Claudio Di Mercurio, one of the amazing olive growers in Penne, Italy.

Dr. Maddock and Dr. Frumkin also found that use of parks and greenspaces for physical activity varies across demographic groups, with men more likely than women to use these spaces for physical activity. In addition, a study of parks in Los Angeles found that Black adults are less likely than white adults to engage in physical activity in parks, while English-speaking Latinos are equally likely and Asian/Pacific Islanders are more likely.

“Some groups—Black, Indigenous, and other people of color, and immigrant and refugee populations, for example—often have experienced historic or current discrimination that hinders their use of natural spaces, and they routinely have less access to high-quality parks,” Dr. Frumkin said. “In addition, children, the elderly, and people with disabilities face challenges in accessing natural spaces. Ensuring that these spaces are safe and easy to navigate, with appropriate programming, could help increase their use of parks and other natural settings.”

With these complexities in mind, the researchers offered four options that health care professionals could implement to encourage the use of parks and other natural settings by their patients.

One is simply to “prescribe” nature contact to patients. “Recommending that patients spend more time in these settings is known as nature prescriptions, or ‘ParkRx,’ and while more research is needed, the studies to date suggest that this approach is effective,” Dr. Maddock said.

Another is for health professionals to model this behavior by engaging in it themselves—this is effective in promoting healthy behaviors while also enhancing the well-being of the health professionals.

A third approach is for health professionals to engage in community efforts that promote the use of outdoor spaces, such as Houston’s Be Well Communities initiative, which is supported by the M.D. Anderson Cancer Center.

Finally, health professionals could help create and maintain parks and greenspaces by steering funds into these efforts through Community Health Needs Assessments, Medicaid funds, and funds from health care conversion foundations.

“It is clear that the use of parks and natural settings for physical activities could be a potentially powerful tool for promoting two important health behaviors simultaneously,” Dr. Maddock said. “This could be especially important given that the majority of Americans do not get enough exercise or spend enough time outdoors.”

Spanakopita “Cigars” Recipe, Spotlight on Pine Nuts, Handling Phyllo, Being Distracted Leads to Overindulging, Climbing Stairs for Longevity

They say cooking can be therapeutic—it’s a type of mindful activity that calls for being focused and it can also fill you with a sense of accomplishment. When you cook for others, that nurturing creates other positive feelings in you as well. There are few recipes that demand as much focus as those that include phyllo, delicate sheets of the thinnest dough that require an equally delicate touch on your part. You also need a lot of patience when building up layers, whether for a sweet baklava or these spinach-filled rolls. Most important, the results are delicious! Focus is also the subject of a new study on why people tend to overindulge. I’m sure you’ll find it as fascinating as I did. 

Spanakopita “Cigars”

  • Spanakopita cigars with phyllo Spanakopita “Cigars”

    Packaged spanakopita, often in canape-sized shapes, can taste rather bland. With a package of frozen phyllo (or fresh if you live near a Greek pastry shop!), you can make this wonderful dish with layers of flavor—the sweetness of the caramelized onions, pine nuts, and currants, the freshness of the parsley and dill, and the zest of the cheeses—all enhanced by the richness of fresh-pressed olive oil. If you have the time, you can steam and chop fresh spinach, but you’ll need a very big volume to achieve two pounds. Frozen is easier to work with—allow it to defrost overnight in the fridge along with the phyllo. This recipe also includes bulgur, a tasty whole grain. You can roll the dough and filling into many different shapes. Long logs, or cigars, are easy to roll up and the shape is less likely to tear the delicate phyllo. Enjoy the process of working with phyllo—it’s easy once you get the hang of it…if you allow yourself time to work at a comfortable pace.

    Ingredients

    • 2 pounds frozen leaf spinach, defrosted
    • 1/3 cup pine nuts
    • Extra-virgin olive oil
    • 1 pound sweet onions, preferably Vidalia, coarsely chopped 
    • 1/2 cup uncooked bulgur
    • 1 cup very finely chopped Italian flat-leaf parsley
    • 1/2 cup other assorted fresh herbs, like oregano, dill, and spearmint
    • 1/3 cup dried tiny currants, such as Zante, or chopped golden raisins
    • 8-ounce block of fresh feta, preferably from Greece
    • 1/2 cup ricotta
    • Coarse sea salt, to taste
    • Freshly ground black pepper, to taste
    • 3 large eggs
    • 16-ounce package frozen phyllo, defrosted
    • 1 tablespoon each white and black sesame seeds

    Directions

    Step 1

    Use your hands to squeeze and discard as much excess liquid from the spinach as you can, then place it in a large colander lined with paper towels over a bowl to continue draining. 

    Step 2

    Heat a large frying pan and, when hot, toast the pine nuts for just a minute or two to bring out their flavor; watch carefully because they can easily burn. Transfer the nuts to a small dish and set aside. Add 2 tablespoons olive oil to the hot pan, then the onions, and cook on low heat for about 20 minutes, stirring often, until the onions are very soft. While they’re cooking, make the bulgur in a small saucepan according to package directions; when done, there should be no water left in the pan.  

    Step 3

    Squeeze any remaining liquid from the spinach and transfer it to a large bowl. Add the pine nuts, onions, bulgur, chopped herbs, and currants or raisins. Finely crumble the feta and add it in along with the ricotta; mix thoroughly. Taste and season with salt and pepper as desired—it may already taste salty enough from the feta. In a separate bowl, lightly beat the eggs, reserving about 1/4 cup. Work the beaten eggs into the spinach mixture. 

    Step 4

    Preheat your oven to 375°F. Line a rimmed sheet pan with parchment paper and set it to one side. Prep the section of countertop where you’ll work with a sheet of parchment paper (see “Quick Kitchen Nugget” in Newsletter #176 for details). Pour olive oil into a small bowl.

    Step 5

    Gently open the phyllo package and unroll the dough onto another rimmed sheet pan lined with parchment paper; immediately cover it with a dry dish towel topped by a damp dish towel. When you’re ready to start, quickly remove one sheet of phyllo and place it on the parchment in front of you. Use the tips of a pastry brush to dab some olive oil across the surface—you don’t need to be too thorough since you’ll be adding more oil with each sheet. Top with another phyllo sheet and dab again, placing the oil on areas where you can see that there’s no oil on the first sheet. Repeat with a third sheet of phyllo. 

    Step 6

    Scoop out a generous half-cup of filling and use your fingers to spread it out in a line across the long end of the dough closest to you, 1 inch in from the edge and from the two short sides. Roll up the phyllo just enough to cover the filling, fold in the outer ends, dab on more oil, and roll up the rest of the way, adding a final dab of oil before transferring the cigar with a bench scraper or wide offset spatula to the parchment-lined sheet pan; cover it with another clean towel. 

    Step 7

    Repeat the process with the rest of the filling and phyllo. Once you’ve rolled all the cigars, remove the towel and use the pastry brush to brush them with the reserved egg, then sprinkle on the sesame seeds. 

    Step 8

    Bake for 30 to 40 minutes until the phyllo crisps and browns.

Pine Nuts

Pine nuts and pine cones

Pesto isn’t the only recipe that benefits from these sweet nuggets, which are actually the seeds of pinecones. Considering their tiny size, pine nuts are nutrient powerhouses: One ounce delivers 4 grams of protein, 1 gram of fiber, 20 grams of polyunsaturated and monounsaturated fat, and good amounts of vitamin E, copper, and manganese. 

Though there are more than 100 species of pine trees, most pine nuts—you might see them packaged or referred to in recipes as pignoli—come from just three of them. Prized and enjoyed for centuries the world over, pine nuts are very slow to produce and hard to harvest. This all explains why they’re so much more expensive than true nuts. So you’ll want to use them judiciously. To preserve their flavor, store them in a sealed bag in your fridge or freezer, not on a cabinet shelf. To bring out that flavor, toast them in a warmed, dry pan for a minute or two before using them in recipes.

Handling Phyllo

Unless you’re lucky enough to live near a Greek or Middle Eastern market that makes and sells its own phyllo, look for frozen versions at your supermarket. Because it is rolled paper thin, it is tricky to make from scratch at home—though it can be done.

Phyllo sheets are extremely fragile and can dry out and tear easily. A few quick tips will make it easier to work with, no matter what recipe you’re making. First, defrost frozen phyllo overnight in the fridge. About an hour before you use it, place the box on a countertop to bring it to room temperature. 

Before you get started, be sure your work surface is clean and dry. Place a long piece of parchment paper in front of you and another to one side. Gather three clean dish towels; slightly dampen one of them. Have your olive oil and a silicone pastry brush plus your filling at the ready. Line a rimmed sheet pan with parchment.

Gently open the package and unroll the phyllo on the parchment. Immediately cover it with one dry towel topped by the damp towel. Peel back the towels just long enough to take out one sheet of phyllo and place it on the parchment in front of you, then follow your recipe’s directions. 

If you notice any rips that expose filling, cover them with small pieces of phyllo drizzled with oil—no one will be any the wiser! 

For Your Best Health: Being Distracted Leads to Overindulging

Being Distracted Leads to Overindulging

New research published by the American Psychological Association in the Journal ofPersonality and Social Psychology aims to unravel the mystery of why we overindulge despite good intentions. The study looked at how distraction affects “hedonic consumption,” or buying and using products and experiences because they make us feel good and not necessarily because we need them.

“On any given day, a person may take great pleasure from one or more of these activities, yet people often consume more hedonic goods than they want or than is good for them,” said lead author Stephen Lee Murphy, PhD, of Ghent University in Belgium.

One reason for this overconsumption may be distraction, according to Dr. Murphy. When people are distracted while engaging in a hedonic activity, research suggests, they are likely to experience less enjoyment from it than if they were fully focused. That may lead to feelings of dissatisfaction and drive more consumption to compensate for the shortfall. If you tend to do other things while eating dinner, for instance, you risk overconsuming later on, possibly because the distraction caused you to enjoy your meal less—you weren’t sated because you weren’t focused on the pleasure of eating in the moment.

To better understand the role of distraction in overconsumption, the researchers first conducted an experiment involving 122 participants (mostly female and mostly between the ages of 18 and 24) who reported on how much they expected to enjoy their lunch before eating it. They were then asked to eat their lunch under one of three conditions: no distraction, moderate distraction (watching a video), and high distraction (playing Tetris). After lunch, participants reported on their actual enjoyment, satisfaction, desire for further gratification, and amount consumed. They also reported on their snacking later in the day.

Participants who ate while distracted reported lower enjoyment and satisfaction, which was associated with increased snacking afterward and a more general desire for further gratification.

The researchers believe that this proposed effect, which they called hedonic compensation, likely applies to activities beyond eating. For example, people who are distracted while watching a movie or playing a game may be more likely to engage in additional consumption, like checking social media, to compensate for a diminished enjoyment of the original activity.

The researchers also followed 220 participants aged 18 to 71 (again mostly female) for a week to investigate this broader effect beyond food. Participants filled out seven brief surveys per day via their smartphones regarding their hedonic consumption, distraction, and satisfaction. As with the food-based experiment, researchers found that when people were distracted during consumption, they were likely to enjoy a product less than they hoped, feel less satisfied, and experience an elevated need for further gratification.

“Overconsumption often results due to a lack of self-control,” said Dr. Murphy. “However, our findings suggest overconsumption may also often be driven by the simple human desire to reach a certain level of enjoyment from an activity. When distraction gets in the way, it’s likely we may try to compensate by consuming more.”

Dr. Murphy and his colleagues plan to conduct further research to replicate and confirm the existence of a hedonic compensation effect. If confirmed, they have plans to apply interventions that could help people pay more attention to their experiences in an effort to lower the likelihood of overconsumption. “By understanding the key drivers of hedonic overconsumption, we can develop strategies to help prevent its occurrence,” he said.

Climbing Stairs for Longevity

Choose stairs over elevators for your health

Cardiovascular disease is largely preventable through actions like exercise. However, more than one in four adults worldwide do not meet recommended levels of physical activity. Stair climbing is a practical and easily accessible form of physical activity that is often overlooked, according to research presented at ESC Preventive Cardiology 2024, a scientific congress of the European Society of Cardiology.

To help determine whether climbing stairs, as a form of physical activity, could play a role in reducing the risks of cardiovascular disease and premature death, the study’s authors collected the best available evidence on the topic and conducted a meta-analysis. Studies were included regardless of the number of flights of stairs and the speed of climbing. There were nine studies with 480,479 participants in the final analysis—including both healthy participants and those with a previous history of heart attack or peripheral arterial disease. Ages ranged from 35 to 84 years old and 53% of participants were women.

Compared with not climbing stairs, stair climbing was associated with a 24% reduced risk of dying from any cause and a 39% lower likelihood of dying from cardiovascular disease. Stair climbing was also linked with a reduced risk of cardiovascular disease, including heart attack, heart failure, and stroke.

“Based on these results, we would encourage people to incorporate stair climbing into their day-to-day lives…If you have the choice of taking the stairs or the lift, go for the stairs, as it will help your heart,” said study author Dr. Sophie Paddock of the University of East Anglia and Norfolk and Norwich University Hospitals National Health Service Foundation Trust in Norwich, UK. “Even brief bursts of physical activity have beneficial health impacts, and short bouts of stair climbing should be an achievable target to integrate into daily routines.”
