Spinach-and-Cheese-Stuffed Shells Recipe, Spotlight on San Marzano Tomatoes, Grating Parmigiano-Reggiano, Reducing Type 2 Diabetes Risk, and A Motivation Reboot

As the nights get cooler, warm, nourishing meals become even more tempting palate-pleasers. My recipe for stuffed shells truly satisfies—it’s one of the new seasonal recipes in the latest edition of my online cookbook Savor the Season: Autumn 2024. Put together family style, it’s a great dish for large gatherings—everyone can dig in on their own. It’s also a very filling meatless option. You’ll read why that’s important in the diabetes-prevention research I’m sharing. Then, to get a motivation boost for healthier living, take a look at some top tips from a leading fitness expert to help you stay on track with your exercise goals.

Spinach-and-Cheese-Stuffed Shells

  • Spinach-and-Cheese-Stuffed Shells Spinach-and-Cheese-Stuffed Shells

    This dish doesn’t just taste great; its pretty presentation will wow family and guests alike. You can make my fresh tomato sauce up to three days in advance, or use 3 cups of your favorite high-quality store-bought sauce for faster prep.

    Ingredients

    For the tomato sauce:

    • 3 tablespoons extra virgin olive oil
    • 4 large garlic cloves, minced
    • 1 cup grated yellow or Vidalia onions
    • One 6-ounce can tomato paste
    • 1/2 cup red wine
    • One 28-ounce can whole tomatoes, preferably San Marzano
    • 1/2 teaspoon dried oregano
    • Pinch of sea salt, more to taste

    For the shells:

    • 1 pound jumbo pasta shells
    • 2 teaspoons sea salt
    • 1 pound mozzarella
    • 1 pound ricotta cheese
    • 2 cups freshly grated Parmigiano-Reggiano cheese, divided use
    • 1 cup cooked spinach, well chopped
    • 2 tablespoons extra virgin olive oil, plus more for baking 
    • 1 egg, beaten
    • 1/2 teaspoon dried oregano
    • 1/4 teaspoon freshly grated nutmeg
    • 1/4 teaspoon freshly ground black pepper

    Directions

    Step 1

    Make the sauce: Heat a large saucepan. When hot, add the olive oil, garlic, and onions, and sauté until soft but not browned. Push the vegetables to the outside of the pan and add the tomato paste in the center. Sauté the paste until it browns, to release its flavors. Deglaze the pan with the red wine, then add the tomatoes, oregano, and salt. Use a potato masher to gently crush the tomatoes. Simmer for 20 minutes (or more) while you prepare the shells. 

    Step 2

    Make the stuffed shells: Bring a large pot of water to a rapid boil and add the shells and the salt. Cook according to package directions for al dente (don’t overcook, as the shells will soften more in the oven). 

    Step 3

    While the shells are boiling, line a rimmed sheet pan with parchment paper and set aside. Preheat your oven to 375°F. Cut the mozzarella into small cubes. Place the cubes in a large bowl along with the ricotta, 1 cup grated Parmigiano-Reggiano, spinach, olive oil, egg, oregano, nutmeg, and black pepper; mix thoroughly. 

    Step 4

    Drain the shells, place them on the prepared sheet pan, and use a small spoon to stuff them with the spinach-cheese mixture. Lightly coat a large round or rectangular baking dish with olive oil and add three-quarters of the sauce; use an offset spatula to spread it out evenly. 

    Step 5

    Place the filled shells in the baking dish in a festive pattern, brush the tops of the shells lightly with olive oil, and cover with the rest of the Parmigiano-Reggiano. Bake for 30 minutes or until the cheese topping is thoroughly melted and slightly browned. Serve with the rest of the tomato sauce on the side.

    Yields 4 to 6 servings

Healthy Ingredient Spotlight: San Marzano Tomatoes

Healthy Ingredient Spotlight

San Marzano Tomatoes

San Marzano Tomatoes

These uniquely shaped Italian tomatoes have long been considered the ultimate in sweetness, but as we’ve seen with olive oil and balsamic vinegar, it’s important to know what’s real and what isn’t. True San Marzano tomatoes are grown in Sarnese-Nocerino, near still-active Mount Vesuvius in the Campania region of Italy. The volcanic soil is responsible for the tomato’s near-perfect balance of sweetness and acidity.  

In recent years, consumers in the US have sued companies whose labels imply that the cans contain San Marzano tomatoes when they don’t. This is not to say that other tomatoes aren’t tasty, but if you want the real thing, look for labels with two essential logos: the red-and-yellow DOP (denominazione d’origine protetta,ordesignation of protected origin) stamp from the EU and the colorful logo of the Agro Sarnese-Nocerino Consorzio, which is the local consortium that makes sure the tomatoes are grown according to its rules. Also, San Marzano tomatoes are always canned whole, peeled, and only in their own juice.

Grating Parmigiano-Reggiano

Grating Parmigiano-Reggiano

If you’re a regular Newsletter reader, you know that only Parmigiano-Reggiano is true “Parmesan” cheese and it will have the word imprinted with a dot pattern all around the rind. How you grate it for a recipe, like my stuffed shells, or for a garnish on, say, Caesar salad, is more nuanced. It depends in part on whether the cheese is to seamlessly meld into a sauce, for instance, or stand out in the form of generous shavings. A sturdy vegetable peeler is a great way to get thin, narrow shavings: Run it along the edge of the wedge. For wide shavings, run a cheese plane over the surface of your wedge. Need a small amount of finely grated cheese? Pull out your microplane grater and shave the cheese right over your dish. For a larger amount, try a box grater—its four sides offer many options (place it over a large sheet of parchment paper to catch the gratings). If you want a very large amount, look to your food processor. Most steel blades will turn cubes into shreds. For a near-powder that will melt easily, Cuisinart has a very fine cheese grating blade that works in seconds—just cut off the rind, cut the cheese into pieces that will fit in the machine’s feed tube, and process. 

For Your Best Health: Reducing Type 2 Diabetes Risk

Reducing Type 2 Diabetes Risk

We know about the risks for heart disease and some forms of cancer associated with eating too much red and processed meat. Now an analysis of studies that included nearly two million people across 20 countries has also linked these foods to a higher risk for developing type 2 diabetes, a chronic condition that has reached epidemic proportions in the US, according to the National Institutes of Health. (Earlier studies made the association but had varying results.) This research, published in The Lancet Diabetes and Endocrinology, also looked at whether there’s a link between poultry and diabetes.

The team of scientists, led by researchers at the University of Cambridge in the UK, found that eating 50 grams of processed meat a day—that’s about 2 slices of ham—was associated with a 15 percent higher risk of developing type 2 diabetes in the next 10 years. Eating 100 grams of unprocessed red meat a day—that’s roughly a 3-ounce steak—was associated with a 10 percent higher risk. Eating 100 grams of poultry a day was associated with an 8 percent higher risk, but when further analyses were done to test the findings under different scenarios, the association for poultry consumption became weaker, whereas the associations with type 2 diabetes for both processed meat and unprocessed meat persisted.

Professor Nita Forouhi of the Medical Research Council (MRC) Epidemiology Unit at the University of Cambridge, a senior author on the paper, said, “Our research provides the most comprehensive evidence to date of an association between eating processed meat and unprocessed red meat and a higher future risk of type 2 diabetes. It supports recommendations to limit the consumption of processed meat and unprocessed red meat to reduce type 2 diabetes cases in the population. While our findings provide more comprehensive evidence on the association between poultry consumption and type 2 diabetes than was previously available, the link remains uncertain and needs to be investigated further.”

The team used theglobal InterConnect project for their work. It’s an approach that allows researchers to analyze individual participant data from diverse studies, rather than being limited to published results. This enabled the authors to include as many as 31 studies in this analysis, 18 of which had unpublished findings on the link between meat consumption and type 2 diabetes. By including this previously unpublished study data, the authors considerably expanded the evidence base and reduced the potential for bias from the exclusion of existing research, they explained.

Said Professor Nick Wareham, director of the MRC Epidemiology Unit and a senior author on the paper, “InterConnect enables us to study the risk factors for obesity and type 2 diabetes across populations in many different countries and continents around the world, helping include populations that are underrepresented in traditional meta-analyses…Using harmonized data and unified analytic methods across nearly two million participants allowed us to provide more concrete evidence of the link between consumption of different types of meat and type 2 diabetes than was previously possible.”

A Motivation Reboot

ACE Fitness, the leading organization for fitness professionals, recently published an inspiring blog on staying motivated, written by fitness expert Len Kravitz, PhD, coordinator of exercise science at the University of New Mexico, and students in his Introduction to Exercise Science course. Here are some of the ideas, abbreviated for space, that can help keep you on track with health and fitness goals, important because, as Dr. Kravitz pointed out, 80 percent of adults don’t meet current guidelines for aerobic exercise or resistance exercise. “These tips help target a person’s self-efficacy to adopt an exercise program and avoid dropping out,” he wrote. “As you read through this list, identify those strategies that resonate with you and fit best with your lifestyle, then incorporate those that will make the biggest impact.”

Set realistic health and fitness goals. Make sure they match your abilities, health, and lifestyle. Also break down even short-term three-month goals into smaller, more achievable segments of two to three weeks.

Create a weekly schedule that includes blocks of time for exercise. This helps with consistency.

Diversify. Mix up activities within each type of exercise—cardio, strength training, and flexibility. 

Track your progress. Seeing your achievements in black and white helps keep you enthusiastic. 

Create or join a network of fitness friends. Exercise loves company! 

Give yourself rewards. Treat yourself to new exercise clothes or gear, flowers, or something special you’ve been eyeing. 

Aim for consistency over intensity. Slow and steady wins the race. 

Set reminders. Use your smartphone to ping you 15 minutes before your scheduled workouts.

Create a vision board. This is a real or virtual poster composed of photos, drawings, and quotes that inspire you. 

Go small if needed. Some people find it easier to work out in 10-minute sessions—build up to three a day and you’ll meet daily recommendation of 30 minutes.

Get guidance. Consider hiring a personal trainer to provide expertise, guidance, education, and motivation tailored to you. This could be the smartest money you’ll ever spend on yourself and pay big dividends.

Late Summer Fruit Salad Recipe, Spotlight on Nectarines, Zesting-then Squeezing, Ultra-Processed Foods (UPFs) and Your Sleep, Preventing Falls

It’s still stone fruit season—the perfect excuse for a luscious fruit salad with a zesty dressing. My recipe is a great example of healthy eating that still tastes indulgent. Enjoying “whole” foods, meaning foods in their most natural state, is the antidote to the dangers of ultra-processed foods, which now include insomnia. Read more on this below, along with a new advisory on avoiding falls for people over 65—food for thought for anyone at risk for falling, regardless of age.

Late Summer Fruit Salad

  • Stone fruit salad Late Summer Fruit Salad

    Stone fruit—nectarines, peaches, and plums—are the stars of this juicy dessert, with figs, berries, and a sweet and citrusy dressing in supporting roles. This salad, high in antioxidants, also makes a delicious breakfast

    Ingredients

    • 2 nectarines
    • 2 plums
    • 2 peaches
    • 1/4 cup extra virgin olive oil
    • 2 tablespoons apple balsamic vinegar 
    • 1 tablespoon local honey 
    • Zest and juice of 1 lime (see “Quick Kitchen Nugget” in newsletter)
    • 1 tablespoon chopped spearmint leaves 
    • 2 fresh figs, quartered
    • 1 cup whole blackberries, rinsed and patted dry

    Directions

    Pit and section the stone fruit, then place in a large serving bowl. In a small bowl, whisk together the olive oil, vinegar, and honey. Whisk in the lime juice, zest, and mint. Pour the dressing over the fruit in the bowl and toss gently. Allow the juices and the dressing to meld for 30 minutes. Just before serving, arrange the figs and blackberries on top of the stone fruit.

    Yields 4 servings

Healthy Ingredient Spotlight: Nectarines

Healthy Ingredient Spotlight

Nectarines

Nectarines and plums

Think of nectarines as peaches’ little siblings. The main difference between the two popular fruits is simply genetic—nectarines lack the fuzz gene that peaches have. Also, nectarines tend to be smaller and firmer yet sweeter and more intensely flavored and scented than peaches…a strong aroma is a key sign of ripeness. 

As with peaches, there are dozens of varieties to choose from, though they fall into the same main categories: freestone and cling free (cling-free varieties making slicing much easier) as well as white and yellow flesh. Nectarines are antioxidant rich and have twice the amount of vitamin A and slightly more vitamin C and potassium than peaches, along with vitamin E, B vitamins, calcium, fiber, and some iron. 

To ripen nectarines, store them at room temperature until they’re no longer firm. If you can’t eat them right away, you can refrigerate them, but for no more than three to five days.

Zest, then Squeeze 

Whenever a recipe calls for zest and juice from a piece of citrus, always zest first, optimally with a handheld Microplane grater. It’s not only easier than trying to zest halves, but you’ll also get the most zest. When juiving, if you’re using a handheld press, always position the fruit cut-side down into the empty cup to extract the most juice.

For Your Best Health: Why Those Chips Are Wrecking Your Sleep

For Your Best Health

Why Those Chips Are Wrecking Your Sleep

We know that ultra-processed foods (UPFs) are the unhealthiest food choices because they have the highest levels of saturated fats, starches, and added sugars plus all sorts of additives like artificial colors and flavors; are devoid of nutrients; and have virtually no fiber. Packaged baked goods and snacks, frozen foods, and processed meats are typically considered ultra-processed. Much of the research on the detriments of UPFs has looked at the links between these foods and health conditions such as diabetes, obesity, and cancer. Now a new study has added sleep problems, including chronic insomnia, to that list. This can have a snowball effect on health because sleep disorders and insomnia have independently been linked with anxiety and depression as well as health conditions like diabetes and heart disease. With sleep health now a wellness goal on its own right, a better diet can be one way to get there.

Lead investigator Marie-Pierre St-Onge, PhD, associate professor of nutritional medicine and director of Columbia University Irving Medical Center of Excellence for Sleep & Circadian Research, said, “At a time when more and more foods are highly processed and sleep disturbances are rampant, it is important to evaluate whether diet could contribute to adverse- or good-quality sleep. Our research team had previously reported associations of healthy dietary patterns, like the Mediterranean diet, with a reduced risk of insomnia and poor sleep quality (both cross-sectionally and longitudinally), and high-carbohydrate diets with an elevated risk of insomnia.”

For this cross-sectional study, Dr. St-Onge and some of her colleagues included 38,570 French participants with a mean age of 50 who completed a sleep questionnaire and at least two 24-hour dietary records. An analysis revealed a statistically significant association between ultra-processed food intake and chronic insomnia, independent of participants’ sociodemographic, lifestyle, diet quality, and mental health status. Overall, the study participants got 16 percent of their daily energy from UPFs. Nearly 20 percent of participants reported symptoms of chronic insomnia, and this group tended to eat more ultra-processed foods.

There are various reasons for the diet-sleep link. First, people who eat more saturated fat, trans fat, sodium, and free or added sugars tend to eat less fruit, vegetables, legumes, and seafood, which are all sources of sleep-promoting compounds, the researchers pointed out. Also, ultra-processed foods are highly inflammatory and can negatively affect the gut microbiome—and the gut microbiome is known to play a role in the quality of your shuteye. 

Fitness Flash: Preventing Falls

Preventing Falls

The US Preventive Services Task Force (USPSTF), a volunteer group of experts in different fields from across the country, recently issued its guidance regarding preventing falls in people over age 65. According to the CDC, over 14 million Americans, or one in four adults ages 65 and older, report falling each year, and for about 37 percent, doing so resulted in an injury that required medical treatment or restricted their activity for at least one day.

After its review of existing research, the USPSTF concluded with moderate certainty that exercise interventions provide a moderate net benefit and that multifactorial interventions, such as three-dimensional exercises (movement through all three spatial planes or dimensions: forward and back, side to side, and up and down), provide a small net benefit in preventing falls and fall-related morbidity in older adults at increased risk for falls. Effective exercise interventions include supervised individual physical therapy and group exercise classes. 

While the USPSTF stated that it’s difficult to identify specific components of exercise that are particularly effective, the most commonly studied exercise components were gait, balance, and functional training, followed by strength and resistance training, flexibility, and endurance training. A smaller number of trials included three-dimensional exercise, such as group dance or tai chi classes. The most common frequency and duration for exercise interventions was two to three sessions per week for 12 months, although the duration of the studies ranged from two to 30 months. 

The USPSTF also recommended that a program be tailored to each individual based on the findings of a health and risk factor assessment that might include balance, gait, vision, postural blood pressure, medication, environment, cognition, and psychological health. This could be done by your doctor or another expert familiar with your health history so that he or she can factor in any chronic medical conditions, medications taken, and alcohol use as well whether you had a prior fall, all of which could affect your fall risk. 

The USPSTF statement included a reminder about the multiple health benefits associated with physical activity that go beyond fall prevention: a lower risk of cardiovascular disease events, cardiovascular disease mortality, and all-cause mortality, as well as lower blood pressure, lower risk of type 2 diabetes, and lower risk of high cholesterol. It added: “The US Department of Health and Human Services recommends that adults do at least 150 to 300 minutes per week of moderate-intensity—or 75 to 150 minutes per week of vigorous-intensity—aerobic physical activity, as well as muscle-strengthening activities of moderate or greater intensity and that involve all major muscle groups, twice a week or more.”

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.”

Taste of Summer Salad Recipe, Spotlight on Burrata, How to Rinse Lettuce and Break the Chronic Stress-Comfort Food Link, Get Moving for Better Quality of Life

When the temp nears 90, the last thing I want to do is to cook, yet at the same time I want to savor a delicious meal. This salad checks off all the boxes. If you haven’t yet tried burrata, this is a wonderful introduction. I’m also sharing findings from two new studies, one on the link between stress and weight gain and the other on yet more benefits of exercise, a known stress-buster. 

Taste of Summer Salad

  • Burrata and Fresh Peach Salad Taste of Summer Salad

    The perfect summer salad has seasonal ingredients that can be enjoyed whole, or as is, no cooking required. I love a blend of sweet and savory ingredients, like juicy peaches and slightly bitter greens. This dish takes just a few minutes to put together but offers exquisite flavors and textures in every bite. Get creative if the exact ingredients aren’t available at your famers’ market—nectarines, cantaloupe, or honeydew chunks are excellent swaps for the peaches, and walnuts or pine nuts can sit in for the pistachios. 

    Ingredients

    • 4 cups mixed lettuces
    • 8 ounces whole burrata or four 2-ounce minis
    • 4 ripe peaches
    • 4 ounces shelled pistachios
    • Extra virgin olive oil, to taste
    • Balsamic vinegar of Modena, to taste
    • Freshly ground black pepper, to taste

    Directions

    Arrange equal amounts of the lettuce on four dishes. If using a whole burrata, cut it into four equal slices or wedges and arrange on top of the greens; if using minis, center a whole one on the greens. Slice the peaches (leave the skins on) and fan out the sections. Top with the pistachios and liberally drizzle with olive oil. Sprinkle on a few drops of the balsamic and some black pepper.

Bravo, Burrata

When burrata first hit our shores—its Italian origins can be traced back to Puglia—it was a taste sensation most easily found at restaurants. Now that its popularity has grown, it’s readily available in grocery stores, often from the same fine cheese companies that produce mozzarella.

Burrata looks very much like mozzarella, but the ball-shaped pouch is filled with a luscious, runny mix of cream and cheese. It can weigh anywhere from 8 ounces to 2 pounds. Mini burratas are typically 2 ounces apiece, and are handy for creating individual plates and for snacking—add a drizzle of fresh-pressed olive oil and a few drops of balsamic vinegar from Modena.

Rinsing Lettuce

Rather than spraying lettuce leaves with water from the faucet, try giving them a bath in a large bowl of cool water. Swirl the leaves in the water and then wait 10 minutes for gravity to draw all the dirt to the bottom of the bowl. Then lift out the leaves without agitating the water and pat them dry. If you want to finish with a lettuce spinner, don’t overfill the basket, or it won’t work well. 

For Your Best Health: Break the Chronic Stress-Comfort Food Link

For Your Best Health

Break the Chronic Stress-Comfort Food Link

When you’re stressed, a high-calorie treat may seem like the soothing go-to. But according to scientists from the Garvan Institute of Medical Research in Sydney, Australia, stress combined with comfort food creates changes in the brain that drive more eating, boost cravings for sweets in particular, and lead to excess weight gain. That’s a lot of downside!

“Our findings reveal stress can override a natural brain response that diminishes the pleasure gained from eating—meaning the brain is continuously rewarded to eat,” says Herbert Herzog, PhD, a professor and visiting scientist at the Garvan Institute and senior author of the study “Critical role of lateral habenula circuits in the control of stress-induced palatable food consumption” published in the journal Neuron. 

To understand what drives eating habits, the team used a mouse model to investigate how different areas in the brain respond to chronic stress under various diets. “We discovered that an area known as the lateral habenula, which is normally involved in switching off the brain’s reward response, was active in mice on a short-term, high-fat diet to protect the animal from overeating. However, when mice were chronically stressed, this part of the brain remained silent, allowing the reward signals to stay active and encourage feeding for pleasure, no longer responding to satiety regulatory signals,” explains first author Kenny Chi Kin Ip, PhD. “We found that stressed mice on a high-fat diet gained twice as much weight as mice on the same diet that were not stressed.”

The researchers discovered that at the center of the weight gain was the molecule NPY, which the brain produces naturally in response to stress. When the researchers blocked NPY from activating brain cells in the lateral habenula in the stressed mice on a high-fat diet, the mice consumed less comfort food, resulting in less weight gain.

The researchers next performed a sucralose preference test, allowing mice to choose to drink either water or water that had been artificially sweetened. “Stressed mice on a high-fat diet consumed three times more sucralose than mice that were on a high-fat diet alone, suggesting that stress not only activates more reward when eating, but specifically drives a craving for sweet, palatable food,” says Dr. Herzog. “Crucially, we did not see this preference for sweetened water in stressed mice that were on a regular diet.”

“In stressful situations it’s easy to use a lot of energy, and the feeling of reward can calm you down—this is when a boost of energy through food is useful. But when experienced over long periods of time, stress appears to change the equation, driving eating that is bad for the body long term,” says Dr. Herzog. “This research emphasizes just how much stress can compromise a healthy energy metabolism. It’s a reminder to avoid a stressful lifestyle, and crucially if you are dealing with long-term stress, try to eat a healthy diet and lock away the junk food.”

Get Moving for Better Quality of Life

We know that moderate intensity physical activity that raises your heart rate is known to reduce the risk of a number of diseases, including heart disease, stroke, diabetes, and cancer. But it has the potential to do even more.

As part of a University of Cambridge (UK) study on exercise habits among 1,433 participants aged 60 and above, the team of scientists looked at the link between exercise and health-related quality of life—a measure of health and well-being that includes pain level, the ability to care for oneself, and anxiety/mood level. Lower quality of life scores are linked with an increased risk of hospitalization, worse outcomes following hospitalization, and early death.

Study participants were given a score between 0 (worst quality of life) and 1 (best) based on their responses to a questionnaire and then followed by the researchers so that they could look for changes in behaviors and quality of life. On average, six years after their first assessment, both men and women were doing about 24 minutes less moderate-to-vigorous physical activity per day. At the same time, the total sedentary time increased by an average of around 33 minutes a day for men and around 38 minutes a day for women. 

For every minute a day less of moderate-to-vigorous physical activity measured, quality of life scores dropped by 0.03. This means that an individual who spent 15 minutes less a day engaged in such activity would have seen their score drop by 0.45. Increases in sedentary behaviors were also associated with poorer quality of life—a drop in the score of 0.012 for every one minute a day increase in total sedentary time six years after the first measurement. This means that an individual who spent 15 minutes a day more sitting down would have seen their score drop by 0.18 over the six years.

People who did more moderate-to-vigorous physical activity and spent less time sedentary at their first assessment had a higher quality of life later on. An hour a day spent more active was associated with a 0.02 higher quality of life score. To put the results into context, just a 0.1 point improvement in quality of life scores was linked to a 6.9% reduction in early death and a 4.2% reduction in risk of hospitalization.

“Keeping yourself active and limiting—and where you can, breaking up—the amount of time you spend sitting down is really important whatever stage of life you’re at,” says Dr. Dharani Yerrakalva of the University’s Department of Public Health and Primary Care. “This seems to be particularly important in later life, when it can lead to potentially significant improvements to your quality of life and your physical and mental well-being.”

Because the team measured physical activity and sedentary behavior at different points of time, they say they can be reasonably confident that they have shown a causal link—that is, that quality of life improves because people remain more physically active, for example. As Dr. Yerrakalva explains, “There are several ways in which improvements in our physical behaviors might help maintain a better quality of life. For example, more physical activity reduces pain in common conditions such as osteoarthritis, and we know that being more physically active improves muscle strength, which allows older adults to continue to care for themselves. Similarly, depression and anxiety are linked to quality of life, and can be improved by being more active and less sedentary.” 

Remember that staying active can be a lot more than just going to the gym—dancing, gardening, hiking, and bike riding all fit the bill and are fun. Also, universal guidelines are to do at least 150 minutes of moderate-intensity activity or 75 minutes of vigorous-intensity activity a week. Older adults are also encouraged to break up prolonged periods of being sedentary with light activity, or at least with standing, when physically possible.

The research paper “Associations between change in physical activity and sedentary time and health-related quality of life in older English adults: the EPIC-Norfolk cohort study” was published in Health and Quality of Life Outcomes.
