If there’s such a thing as a grownup vegetable, it’s got to be beets. If you didn’t like them as a kid, it probably has to do with how they were prepared (i.e., reheated out of a can!). But when slow roasted in the oven, their wonderful sweetness emerges, making them a great pairing with the tang of goat cheese or the saltiness of feta. 

Beets are also fantastically packed with nutrients. They owe their rich colors to betalains, a source of antioxidants. Red and purple beets are high in betalains called betacyanins; in yellow beets, you get betalains called betaxanthins (when using these varieties, clean up quickly because they can leave stains). 

Beets are also high in nitrates, compounds that help open blood vessels, giving better flow to the heart and brain. You’ll also get nearly 4 grams of fiber in every cup and lots of potassium. If you’re able to find beets with the tops still attached, use the greens in salads or make a quick sauté—they’ve got beta-carotene, lutein, and zeaxanthin, all good for eye health. All beets do have oxalates, which are linked to kidney stones, so if you’re prone to them, eat beets in moderation, according to the Cleveland Clinic.

Paper, please

Rather than using foil, I prefer to line baking sheets with parchment paper, especially for long roasting times, to avoid exposing food to metal. The box should tell you the temperature that the paper is rated for. It’s possible to find brands listed as safe up to 450°F, but expect to see exposed edges turn brown and brittle after a long time in the oven. According to the experts at Cook’s Illustrated, you can exceed the listed temperature if the cooking time is short, say the 15-20 minutes it takes to bake a pizza.

Friends enjoy being reached out to more than we think, and the more it’s a surprise, the more it’s appreciated, according to research published by the American Psychological Association in the Journal of Personality and Social Psychology.

“People are fundamentally social beings and enjoy connecting with others,” says lead author Peggy Liu, PhD, of the University of Pittsburgh. “There is much research showing that maintaining social connections is good for our mental and physical health. However, despite the importance and enjoyment of social connection, our research suggests that people significantly underestimate how much others will appreciate being reached out to.”

Dr. Liu and her colleagues conducted a series of experiments involving more than 5,900 participants to explore how accurate people are at estimating how much others might appreciate an attempt to connect and what factors might play into that level of appreciation. The experiments involved actions like sending a thank-you note or gift of appreciation to someone with whom they had not interacted in a while or simply recalling the last time they reached out to someone “just because” or “just to catch up” via email, text, or phone after a prolonged period of not interacting with them. Participants were asked to say how much either they or the person they reached out to felt about the contact. Overwhelmingly, people making the gesture greatly underappreciated how meaningful it was to the recipient, especially when it came as a surprise.

“We found that people receiving the communication placed greater focus than those initiating the communication on the surprise element, and this heightened focus on surprise was associated with higher appreciation,” says Dr. Liu. “We also found that people underestimated others’ appreciation to a greater extent when the communication was more surprising, as opposed to part of a regular communication pattern, or the social ties between the two participants were weak.”

Many people have lost touch with others in their lives, whether they’re friends from high school or college or co-workers they used to see at the water cooler before work went remote, according to Dr. Liu. Initiating social contact after a prolonged period of disconnect can feel daunting because people worry about how such a gesture might be received. But these findings suggest that there’s no reason to hesitate.

“I sometimes pause before reaching out to people from my pre-pandemic social circle for a variety of reasons. When that happens, I think about these research findings and remind myself that other people may also want to reach out to me and hesitate for the same reasons,” Dr. Liu says. “I then tell myself that I would appreciate it so much if they reached out to me and that there is no reason to think they would not similarly appreciate my reaching out to them.”

A review of 400 studies involving 164,000 people across the world by University of South Australia researchers revealed what millions of people already know: Fitness trackers, pedometers, and smart watches motivate us to exercise more, such as walking up to 40 minutes more each day (approximately 1,800 more steps), which translates to losing about 1 kilo, or about two pounds, of weight on average over five months. That may not seem like a lot, but the researchers say that from a public health perspective, it is meaningful. “These were not weight loss studies, but lifestyle physical activity studies, so we wouldn’t expect dramatic weight loss,” says Professor Carol Maher, co-author of the review. “The average person gains about 0.5 kg a year in weight creep, so losing 1 kg over five months is significant.”

The findings, published in Lancet Digital Health, support the value of low-cost interventions for tackling the growing epidemic of health conditions partially caused by a lack of exercise, including heart disease, stroke, type 2 diabetes, cancers, and mental illness. Lead researcher and PhD candidate Ty Ferguson says that despite the popularity of these devices, there is widespread skepticism about their effectiveness and accuracy and whether they fuel obsessive behaviors and eating disorders, but the evidence is overwhelmingly positive.

“The overall results from the studies we reviewed show that wearable activity trackers (WATs) are effective across all age groups and for long periods of time,” Ferguson says. “They encourage people to exercise on a regular basis, to make it part of their routine, and to set goals to lose weight.”

There is some evidence that fitness trackers also help lower blood pressure and cholesterol in people with type 2 diabetes and other health conditions. “The other reported benefit is that WATs improved depression and anxiety through an increase in physical activity,” Ferguson adds.

Grilled Pear Salad with Greens and Port Vinaigrette and Peruvian Purple Potato Salad Recipes, Spotlight on Pear Balsamic Vinegar and Pairing with Extra Virgin Olive Oils

Vinegar Essentials, Part I: Pear Balsamic Vinegar

I’m so excited to once again share the magic of vinegar with you. The right vinegar can raise the taste profile of a dish in a unique way, adding deep and complex flavors. Traveling across Europe and tasting new and delightful offerings from renowned master crafters to put together my second curated collection was an amazing experience. Let me start by introducing you to pear balsamic, a fruity vinegar with the richness reminiscent of a traditional balsamic. I’ll also explain how to pair various vinegars with Fresh-Pressed Olive Oil Club offerings so you can get all the benefits of olive oil in even more delicious ways.

Grilled Pear Salad with Greens and Port Vinaigrette

  • Grilled Pear Salad with Greens and Port Vinaigrette Grilled Pear Salad with Greens and Port Vinaigrette

    Peaches or apricots are delicious alternatives to the pears. 

    Ingredients

    • 1/2 cup extra virgin olive oil
    • 3 tablespoons Pear Balsamic Vinegar
    • 1 tablespoon port wine (or more vinegar)
    • 2 teaspoons honey
    • 1/4 teaspoon coarse salt, plus more to taste 
    • 1/4 teaspoon coarsely ground black pepper
    • 8 cups mixed greens, such as romaine lettuce, endive, radicchio, and arugula, torn, chopped, or sliced 
    • 3 ripe pears, such as Bosc, Bartlett, or d’Anjou 
    • 3 tablespoons mascarpone or another soft, creamy cheese 
    • 1/2 cup toasted macadamia nuts, chopped 
    • 1/2 cup pomegranate seeds for garnish (optional) 

    Directions

    Step 1

    Make the vinaigrette: In a jar with a tight-fitting lid, combine the olive oil, vinegar, port, honey, and the ¼ teaspoons of salt and black pepper, and shake vigorously until emulsified. Taste for seasoning, adding more salt if needed. Pour 3 tablespoons of the vinaigrette onto a shallow plate and reserve the remainder. 

    Step 2

    Divide the salad greens among six plates. Cut each pear in half and remove the core. Dip the cut sides in the plated vinaigrette. Set up your grill for direct grilling. Grill the pears, cut sides down, until light grill marks appear, about 5 minutes. 

    Step 3

    While the pears are still warm, arrange a pear half on each salad plate, cut side up, and put a dollop of mascarpone in each cavity. Drizzle with the reserved vinaigrette (shake the jar if necessary), and top with the toasted macadamia nuts and pomegranate seeds, if using.

Healthy Ingredient Spotlight: Pear Balsamic: A modern-day creation from vintage fruit

Spotlight on Pear Balsamic Vinegar

A modern-day creation from vintage fruit

If you’ve ever sampled flavored vinegars, prepare to be blown away by the taste difference in a vinegar crafted from real fruit with time-honored traditions. Alois Gölles Jr., whose father started their orchards in Riegersburg, Austria in the late 1950s, initially began creating fruit wines, juices, and spirits. A trip to Modena, Italy, in the early ’80s inspired him to create a balsamic vinegar from apples rather than grapes. Within a few years, word spread about this unique vinegar, and Alois then set his sights on making a pear balsamic. Interestingly, to preserve the wonderful pear notes, the Pear Balsamic Vinegar is not aged as long as the Apple Balsamic Vinegar in last year’s collection, yet it has the same depth of flavor. 

This enchanting vinegar starts with one of the local cultivars, the Hirschbirne pear. At the time Alois first started using it, the Hirschbirne had almost disappeared from markets because of its astringent taste, but ironically, that’s exactly what makes it perfect for making top-notch vinegar. 

It’s not surprising that this Pear Balsamic Vinegar has the sweet taste of a traditional balsamic as well as its richness: It’s made according to the traditional balsamic vinegar method. First, the fruit is sorted and washed, then it’s crushed and pressed. The resulting pear juice is carefully reduced over low heat until it is quite concentrated before being naturally fermented, first through alcoholic fermentation to produce wine, and then through vinegar fermentation to turn the wine into vinegar. What follows is four years of barrel aging to reduce the vinegar in a very slow fashion—that accounts for the thickness not seen in regular vinegars, the sweetness, the golden-brown color, and the mild taste. 

Food Pairings: Enjoying Pear Balsamic Vinegar

Food Pairings

Enjoying Pear Balsamic Vinegar

This vinegar brings an element of sweetness to bitter greens, to salads with fruits and/or nuts, and to the classic caprese salad. It adds depth of flavor to any dish that includes fresh or poached pears (add it to the poaching liquid!). Include it in your favorite pork recipes. Just a few drops brighten savory dishes, especially winter vegetables, like sweet potatoes, brussels sprouts, fennel, acorn squash, and hearty beans. Drizzle it on blue cheeses and on Brie and other white rind cheeses; yogurt and granola parfaits; carpaccio, terrines, eggplant caponata, and bruschetta; grilled fish; and panna cotta-type puddings and vanilla ice cream. It’s perfect for deglazing and making a quick reduction—whisk it into pan-melted butter and you’ll have an amazing sauce. 

Healthy Kitchen Nugget: Pairing vinegar varieties with extra virgin olive oils

Healthy Kitchen Nugget

Pairing vinegar varieties with extra virgin olive oils 

While I don’t believe in any hard-and-fast rules, I do like to pair milder vinegars with milder oils so that one doesn’t overwhelm the other. If you’re using a bold selection from the Fresh-Pressed Olive Oil Club, go with a bold red wine vinegar. If you’re using a fruitier, milder olive oil, pair it with a fruit-based vinegar. Think about the foods on your plate, too. If you’re making a salad with bitter greens, add sweetness with a sweeter vinegar like a classic balsamic. If you’re making a chopped salad with provolone and salami, a tangy vinegar will balance the richness of the meat and cheese. 

I also like to combine vinegars. For a vinaigrette with great complexity, use half balsamic for sweetness and half red wine vinegar for tartness along with your extra virgin olive oil. The beauty of having a collection of flavorful vinegars is that you can have fun discovering the pairings you like best.

Debunking Common Myths About Extra Virgin Olive Oil (EVOO) Once and for All

The expression “truth in advertising” seems to have gotten lost in the shuffle lately, especially when it comes to extra virgin olive oil, or EVOO. You’re likely to see buzzwords on labels and in ads without any way for you to know if a claim is true. There are also some persistent and confusing myths about EVOO that need to be corrected once and for all! 

As your Olive Oil Hunter, I’d like to set the record straight so that you not only will enjoy the marvelous taste of true extra virgin olive oil but also get all of the healthful benefits from its high level of antioxidants, notably the polyphenols.

Myth: The best olive oil comes from Italy.

Fact: I love Italian olive oil—and I’m in Italy once a year at the optimal harvest time to work with master millers on their best oils. But I spend the other months circling the globe to source the best, just-pressed olive oils—and for half the year, that’s in the southern hemisphere. I can tell you that there are a number of countries that have conditions—like soil and climate—that are just as conducive to growing the right olives as Italy and other countries around the Mediterranean. Farms in Chile and Australia, for instance, grow a diverse variety of olives and produce phenomenal oils. The reason I source different oils each season is because freshness counts—in our summer months, I want you to have the taste of just-pressed olive oil from Chile, which is going to exceed the flavor of an Italian oil that was pressed and bottled six or more months earlier. 

Fresh Pressed Olive Oil Extra Virgin

Myth: If it’s bottled in Italy, it’s a quality oil.

Fact: Many store-bought oils state “bottled in Italy” on the label, but that doesn’t mean the oil was pressed there or when it was pressed. A number of independent consumer investigations over the years have found that many off-the-shelf olive oils contained oils from other countries—they were just put in bottles in Italy—or, worse, that the olive oil was diluted with a lesser oil, like canola. Because none of this has to be disclosed on the label, buyer beware! Not only do these low-quality oils taste unappealing, but you’re also not getting the nutrients you thought you were. 

There’s also an important distinction to be made between an oil mixed from a variety of producers/countries, as described above, and an oil that’s a masterful blend of a few different varietals, all of which were fresh-pressed from the same harvest and shipped quickly to you. The same way that a chef combines herbs and spices for the perfect dish, I bring together different olive varieties to create flavor profiles using the best of what my artisanal growers harvest each season. I might choose just one variety or use up to, say, three to create the oils for each of my collections. 

You’re most likely to find the word “blend” tucked away in a corner of the label on a store-bought brand with no explanation, whereas in the Pressing Report, which I include with every Fresh-Pressed Olive Oil Club shipment, I write in great detail about the olives I chose.

Myth: You can’t use high-heat cooking methods with olive oil.

Fact: Olive oil is wonderful for so much more than drizzling on salads and other cold dishes. Premium EVOO has a smoke point of over 400°F. The antioxidants in high-quality extra virgin olive oil help it stay fresh and also help keep it from oxidizing during sautéing and frying, so cook up a storm! What’s more, raw vegetables cooked in EVOO with either of those methods tend to have more antioxidants as a result, according to research published in the journal Food Chemistry

Myth: Olive oil should taste neutral, not bitter.

Fact: Bitterness is a desirable attribute of an olive oil, alongside pungency and fruitiness. It’s actually a sign of freshness. Great olive oil is often measured by whether it makes you cough when you sip it. The cough reaction tells you the oil is high in healthful polyphenols. A premium EVOO may be described as a one-, two-, or three-cough oil—the more the better! 

There’s a reason store-bought oils taste bland. The highest-quality, best-tasting olive oil comes from olives harvested and pressed when they’re still green and contain only 10% oil—low yield but maximum flavor. Fully ripe olives that have turned black produce three times as much oil but have nowhere near the same taste. This is what many mass producers will use to get more product and why their oils have a lackluster taste. For the Fresh-Pressed Olive Oil Club, I always include a mild EVOO, along with a medium and a bold selection, but it’s chockful of nutrients, and the taste is never bland.

The Olive Oil Hunter News #107

Myth: Olive oil should keep for more than a year.

Fact: That’s pushing the limits of freshness. Time, temperature, and light all conspire to affect olive oil. In terms of time, look for a harvest date on the label, not just an expiration date. You want to buy oil within six to 12 months of harvest. The expiration date doesn’t tell you when that was. In terms of guarding against light, olive oil should be bottled in dark glass, which helps shield it. In terms of heat, never keep your bottles out on the counter, near a window, in a cabinet above the stove, or any area that’s warm. The bottom shelf of a pantry cabinet is best. 

Do take out your olive oil at meals and use it—don’t save it for special occasions. In our house, when we set the table, we put a bottle alongside the salt and pepper—it’s a “sauce” that Mother Nature has made for you, so enjoy it.

Myth: If it’s sold at my gourmet food store, it must be the real thing. 

Fact: When you see the words “extra virgin,” know that they can have a very broad meaning. Extra virgin means that the oil was made from the first pressing of the olives, which is a good thing. But if that olive oil wasn’t made by mechanical means only—without heat or chemicals—and if it wasn’t bottled and shipped right away, it won’t taste much better than a lesser grade. Nor will it have the high levels of polyphenols that give extra virgin olive oil its superfood status and unmistakable taste. 

Myth: The color of the EVOO is a good indicator of quality.

Fact: Many fresh-pressed olive oils are green in color, and that can range from a grassy green to a gold-green. But color isn’t the be-all and end-all indicator of quality. There should be a strong and bright aroma when you bring it to your nose—the bouquet should transport you to the olive grove! And, of course, the flavor should really excite your taste buds. Remember that olive oil is a fruit juice, so there should be a bright fruitiness to it.

Easy Pizza Dough for Personal Pies Recipe, Spotlight on Pizza, White versus Wheat Flour, Why Thinking is Exhausting and Why Daily Exercise is Not

Who doesn’t love pizza? The problem is that it’s often saddled with the “unhealthy” label. But I’m here to tell you that homemade pizza can be delicious and nutritious. It all depends on the ingredients, and by that I of course mean the toppings! And I have some more food for thought: Why thinking is exhausting and why daily exercise nuggets are not (they’re actually invigorating!).

Easy Pizza Dough for Personal Pies

  • Personal Pizzas Easy Pizza Dough for Personal Pies

    Using bread flour is the secret for crusty pizza—one that holds up to a lot of sauce and toppings! You can make two large rounds from this dough, but making individual pizzas is more fun. Note: If you’re able to find instant yeast, you can streamline the technique even further, as it can be mixed with the other dry ingredients for a few seconds before adding the water and oil, before proceeding with the kneading as described. 

    Ingredients

    • 1 1/2 cups warm water, about 110-115°F, plus more as needed
    • 1 teaspoon sugar
    • 2 1/4 teaspoons (or one envelope) active dry yeast
    • 1 teaspoon coarse sea salt
    • 4 cups bread flour, plus more as needed 
    • 4 tablespoons olive oil, divided

    Directions

    Step 1

    Place the water, sugar, and yeast in the bowl of a stand mixer with the dough hook attached. Turn it on for a few seconds to mix and then wait 5 minutes for the yeast to bubble up. 

    Step 2

    With the mixer on the lowest setting, add 3 tablespoons of olive oil, the salt, and the flour to the bowl. Once a doughy mass forms, slowly raise the speed and continue kneading until the dough ball is smooth and elastic, about 8 minutes. If the dough feels too dry, add more water, a scant tablespoon at a time. If too wet, add more flour, a scant tablespoon at a time.

    Step 3

    Lift the dough out of the bowl, remove the dough hook, and pour in the last tablespoon of olive oil, coating the bowl thoroughly. Place the dough back in the bowl, cover it with plastic wrap, and let it rise for about 60 minutes or so (depending on how warm your kitchen is) until double in size and spongy.

    Step 4

    Preheat your oven to 450° or 500°F, depending on how high it goes. Gently transfer the dough from the bowl to a large piece of parchment paper. Use a knife or pastry cutter to cut the dough into quarters. Transfer three of the pieces onto their own sheets of parchment. If the dough is sticky, first sprinkle the parchment paper with flour or some cornmeal. One piece at a time, stretch out the dough with your hands, rotating it by quarter turns until it reaches your desired thickness. The shape—round, rectangle, or oblong—is up to you, but keep a slight lip all along the perimeter. Transfer the pizzas to large baking sheets (you should be able to fit two per sheet). Use scissors to trim the parchment to within two inches of the dough.

    Step 5

    Working in batches as needed based on your oven capacity, bake the pizzas for 8 minutes. Carefully take them out of the oven, add your desired toppings, and return to the oven for another 8 to 10 minutes or until bubbly.

“Healthify” Your Pizza

One of the things I love most about making individual pizzas is that everyone can customize their pie. I like to “healthify” my pizza with loads of veggies, like onions, mushrooms, Brussels sprout halves, and broccoli rabe. Cherry tomatoes are a fun addition when there’s no time to make sauce (or even in addition to it). Topping your pizza right as it comes out of the oven with arugula and a drizzle of olive oil gives it a fresh and slightly peppery finish. Of course, almost any ethnic dish that you’d eat with bread, from chicken tikka marsala to shish kebab, can top your pizza for a delicious twist.

White versus Wheat Flour

Another trick to making pizza good for you is replacing about 25 percent of the white flour with whole wheat or whole wheat pastry flour. Because these flours are the least processed, they retain fiber and nutrients. At the other extreme is 00 pizza flour. It’s been getting more attention lately as Italian brands become more readily available (there’s also 00 flour for pasta, and they’re not interchangeable). It has the silkiest, smoothest texture of all flours and, consequently, retains virtually no fiber. Since, as always, the proof is in the pudding, you might do your own taste test to see the difference and even experiment by using 00 along with some whole wheat flour.

Don’t overthink it!

New research has found that too much mental effort can be as exhausting as physical labor. What’s more, it can cause toxin by-products to build up in the brain (fortunately, they can be recycled during down time). 

Study co-author Mathias Pessiglione, PhD, of Pitié-Salpêtrière University in Paris, France, explains: “Our findings show that cognitive work results in a true functional alteration—accumulation of noxious substances—so fatigue would indeed be a signal that makes us stop working…to preserve the integrity of brain functioning.”

To better understand what mental fatigue really is, Dr. Pessiglione and his colleagues used magnetic resonance spectroscopy to monitor brain chemistry over the course of a workday. They looked at two groups of people: those who needed to think hard and those who had relatively easier cognitive tasks.

They saw signs of fatigue only in the group doing hard thinking. Those participants also had higher levels of glutamate in synapses of the brain’s prefrontal cortex. This supports the notion that glutamate accumulation makes further activation of the prefrontal cortex more costly, meaning that cognitive control is more difficult after a mentally tough workday.

Is there some way around this limitation of our brain’s ability to think hard? “Not really, I’m afraid,” Dr. Pessiglione says. “I would employ good old recipes: Rest and sleep! There is good evidence that glutamate is eliminated from synapses during sleep.” He also advises people to avoid making important decisions when they’re tired.

Weight Training in Daily Spurts

We all know how important weight, or resistance, training is—having strong muscles is essential to staying self-sufficient, especially as we get older. But you may have a hard time getting enthused about going to the gym for heavy-duty pumping iron sessions. New research from Australia’s Edith Cowan University (ECU) found that small amounts of daily activity could well be the most beneficial approach for muscle strength.

For their study, researchers from ECU in collaboration with Niigata University and Nishi Kyushu University in Japan had three groups of participants perform an arm resistance exercise (eccentric bicep contractions) using a weight training machine, and then the researchers measured and compared changes in muscle strength and muscle thickness. 

Each group followed a different training schedule across the four weeks of the study. Two groups performed 30 contractions per week, with one group doing six contractions a day for five days a week (the 6×5 group), while the other crammed all 30 into a single day, once a week (the 30×1 group). The third group only performed six contractions on just one day each week.

After four weeks, the group doing six contractions once a week did not show any changes in muscle strength or muscle thickness. The group doing 30 contractions in a single day did not show any increase in muscle strength, though they had a slight increase in muscle size. The 6×5 group saw an increase of greater than 10 percent in muscle strength along with a slight increase in muscle size.

ECU Exercise and Sports Science Professor Ken Nosaka, PhD, says this and other studies suggest very manageable amounts of exercise done regularly can have a real effect on strength. “People think they have to do a lengthy session of resistance training in the gym, but that’s not the case. Just lowering a heavy dumbbell slowly once six times a day is enough. We only used the bicep curl exercise in this study, but we believe this would be the case for other muscles also, at least to some extent,” explains Dr. Nosaka, adding, “Muscle strength is important to our health. This could help prevent a decrease in muscle mass and strength with ageing. A decrease in muscle mass is a cause of many chronic disease, such as cardiovascular disease, type 2 diabetes, some cancers, dementia, plus musculoskeletal problems such as osteoporosis.”

He stresses that it’s also important to include rest in an exercise regimen. “In this study, the 6×5 group had two days off per week,” he points out. “Muscle adaptions occur when we are resting; if someone was able to somehow train 24 hours a day, there would actually be no improvement at all. Muscles need rest to improve their strength and their muscle mass, but muscles appear to like to be stimulated more frequently.”

Dr. Nosaka also believes that there needs to be more emphasis on making exercise a daily activity, rather than hitting a weekly minute goal. “If you’re just going to the gym once a week, it’s not as effective as doing a bit of exercise every day at home,” he says. The study was published in the Scandinavian Journal of Medicine and Science in Sports.
