Chicken Sausage Skillet Dinner Recipe, Spotlight on Fennel, Wok—A Stovetop Essential, Add Spice for Portion Control, and Mindfulness and Step-tracking Boost Motivation

I love a meal that comes together in one pot with ingredients that create a yummy sauce. I’m using chicken as a change from pork sausage and checking off all the boxes by combining it with fresh peas and new potatoes. There’s also a reason for the sprinkle of peperoncino—a study showed that chili peppers can help you eat less while still feeling satisfied. And if you’re looking for added motivation to get involved in warm-weather activities, there’s an app that can help.

Chicken Sausage Skillet Dinner

  • New potatoes and fresh peas Chicken Sausage Skillet Dinner

    Parboiling the potatoes cuts the cooking time of this flavorful dish. The recipe makes a delicious dinner, but it’s also great for a picnic since you can enjoy it at room temperature—for safety, remember to consume hot or cold foods within an hour of taking them off the stove or out of the fridge. Note: If you can only find chicken sausage links, simply squeeze them out of their casings and into the hot pan.

    Ingredients

    • 1 pound fingerling or new red potatoes
    • 3 tablespoons extra virgin olive oil, plus more for drizzling
    • 1 pound chicken sausage
    • 1 teaspoon fennel seeds
    • 1/4 teaspoon peperoncino (Italian red pepper flakes)
    • 1 cup homemade or low-sodium store-bought chicken stock
    • 1 cup freshly shelled green peas
    • 1 cup freshly grated Parmigiano-Reggiano, divided use
    • Freshly ground black pepper to taste

    Directions

    Step 1

    Parboil the potatoes in salted water for 10 minutes; drain. When cool enough to handle, cut them in half.

    Step 2

    Heat a large flat-bottom wok over medium heat. When hot, add the olive oil and the chicken sausage, breaking it up with a wooden spoon and stirring until the meat is opaque and cooked through. Add the fennel seeds, peperoncino, and potatoes and sauté with the chicken until the potatoes crisp.

    Step 3

    Add the stock and use the spoon to release any bits of fond on the bottom of the pan. Raise the heat and cook down the stock until reduced by half. Add the peas and half the Parmigiano-Reggiano, stirring constantly (the sauce will thicken as the cheese melts).

    Step 4

    Off the heat, add black pepper to taste. Top each portion with more Parmigiano-Reggiano and a drizzle of olive oil.

    Yields 4 servings

Fennel Seed

Members of the Fresh-Pressed Olive Oil Club know that I’m a fresh fennel fan, but I also love fennel seeds, harvested from the plant’s flowers and then dried. While they’re ubiquitous in Italian pork sausages, they’re not always included in chicken sausages, so I’ll simply add them for their distinctive light licorice taste. Part of the same family as anise, fennel is more subtle.

Delicious in pork dishes, fennel seeds are also a great addition to summer potato, seafood, and pasta salads. When shopping, look for fennel seeds that are a pale green, not grey or brown, for freshness. If a recipe calls for ground fennel, simply pulverize them in a spice or coffee bean grinder.

Wok: A Stovetop Essential

Did you know that a flat-bottomed wok can lead a double life as a frying pan? With higher sides and a wide surface area, a wok should be used for more than stir-fries—often it can sear, sauté, and even deep fry, not to mention cook stews and curries. Many companies now manufacture high-quality woks made of carbon steel that cost less than $70 and will last for decades with the proper care.

For Your Best Health: Add Spice for Portion Control

Add Spice for Portion Control

It’s a provocative—and potentially tasty—concept: Making meals slightly spicier can lead to eating fewer calories, according to Penn State University Sensory Evaluation Center researchers who examined how increasing “oral burn,” the spicy taste from ingredients like chili peppers, affects how much food people consume during a meal.

“We know from previous studies that when people slow down, they eat significantly less,” said Paige Cunningham, PhD. “We suspected that making a meal spicier might slow people down. We thought, let’s test, under controlled experimental conditions in the lab, if adding a small amount of spice, but not so much that the meal is inedible, will make people eat slower and therefore eat less.”

The researchers found that increasing spiciness slightly with dried chili pepper did indeed slow down eating and reduce the amount of food and energy consumed at a meal, all without negatively affecting the palatability of the dish.

The team conducted three related experiments with a total of 130 adults who were served one of two lunch meals—beef chili or chicken tikka masala—in one of two versions: mild or spicy. The spiciness level was controlled by carefully varying the ratio of hot versus sweet paprika added to the dishes while keeping chili flavor constant.

The researchers recorded participants on high-definition video while they ate their meals to monitor their eating behaviors. From the videos, the team measured the amount of food and water consumed, meal duration, eating speed of grams per minute, bite rate, and bite size and collected ratings on appetite, liking, and spiciness before and after the meal.

The study suggests that the reduction in intake is driven by changes in what are called oral processing behaviors. Specifically, participants ate the spicier meals more slowly. Dr. Cunningham explained that a slower eating rate often means food is in the mouth longer, which can help signal fullness and lead to eating less. Other studies that slow eating rate by manipulating texture have shown similar effects, she said.

“What’s critical here is that the reduction in intake occurred without negatively impacting how much participants liked the food,” said John Hayes, PhD, Penn State professor of food science, director of the Sensory Evaluation Center, and corresponding author on the paper.

He added that water intake didn’t differ significantly between spicy and mild meals, suggesting that one seemingly obvious explanation, that people drank more water and filled up faster, was not the primary reason people ate less. “This is why we need to do empirical studies of behavior, because what you might intuitively expect is often not the case,” Dr. Hayes said.

He also noted that appetite ratings made before and after the meals were similar, suggesting participants still felt full after the spicy meal, despite eating less of it. “This points to added chilies as a potential strategy for reducing the risk of energy overconsumption,” he said. “While portion control wasn’t the explicit goal of this study, our results suggest this might work. Next time you’re looking to eat a little less, try adding a blast of chilies, as it may slow you down and help you eat less.”

The team is now focused on understanding how oral burn can impact other eating behaviors, like snacking.

Mindfulness and Step-tracking Boost Motivation

A study from the Centre for Motivation and Behaviour Change at the University of Bath in the UK and published in the journal Mental Health and Physical Activity shows that combining step-tracking with mindfulness training delivered via a mobile app can significantly boost the desire to exercise.

While step-tracking alone versus step-tracking alongside a daily mindfulness training course had similar impacts on short-term physical activity, with all study participants exercising more than before the study, those in the mindfulness group did increase their intentions to stay active, a key psychological driver of lasting behavior change.

Lead researcher Masha Remskar, PhD, from the department of psychology at Bath, said, “Our findings show that even short-term mindfulness training combined with step-tracking can make people want to move more, which could have lasting benefits. Helping people build that internal drive towards behavior is essential, especially at a time when many people are struggling to stay active.”

The trial involved 109 adults in England who weren’t meeting recommended activity levels. Over 30 days, all participants were asked to aim for 8,000 steps a day using a basic tracker. Half also followed a daily mindfulness program via a mobile app, with short practice sessions focused on body awareness, movement, and exercise. The sessions that participants used were created by the research team, in collaboration with the Medito Foundation, and are available through the free app Medito.

By the end of the month, both groups had become more active. On average, participants in the mindfulness group increased their activity by approximately 373 minutes of moderate exercise per week, while those in the steps-only group averaged 297 minutes per week. Those who used the mindfulness app also reported a significantly stronger intention to keep exercising, which may suggest that a gradual longer-term change was beginning (the current study did not include a longer follow-up period to explore this trend further).

“Intentions are one of the strongest predictors of future behavior,” Dr. Remskar added. “What’s exciting is that adding a mindfulness component to step-tracking seems to help people mentally commit to being more active. We are particularly excited to have worked with a non-profit collaborator, Medito, which means that the mindfulness program is freely available to anyone who wishes to try it for themselves.”

“This is an exciting first study that combines mindfulness training with strategies designed to help people move more and internalize their motivation for physical activity,” said Max Western, PhD, study co-author and senior lecturer in the department of health at Bath. “There is a lot of potential here and we are keen to refine these tools to make them more engaging and effective, especially for people balancing competing demands.”

Future studies will test whether the motivational benefits seen here translate into real-world behavior over time.

Smashed Potato Pie Recipe, Spotlight on New Potatoes, Sizing Up Cast-Iron Skillets, More Reasons to Boost Plant-Based Proteins and Easing Concerns About Soreness After Activity

Viewers of the Great British Baking Show know that pies with “soggy bottoms” are a top fear of its contestants. There are no worries about that with this crust made from potatoes—a tasty version of a quiche that’s a win-win. So are the two studies I’m sharing. One busts the myth that we experience greater muscle soreness after workouts, a concern that leads many to scale back on workouts unnecessarily. The second provides food for thought from research that included data from 101 countries: it found that there are longevity benefits to getting more daily protein from plants.

Smashed Potato Pie

  • Smashed potato pie Smashed Potato Pie

    Whether you want to skip the gluten of a typical pie crust or are simply looking for a tasty alternative, using new potatoes is a delicious choice. 

    Ingredients

    • 2 pounds new red or small Yukon Gold potatoes, rinsed and left whole
    • 1 tablespoon plus 2 teaspoons sea salt, divided use
    • 5 tablespoons extra virgin olive oil, divided use
    • 1 medium onion, finely diced
    • 1 red bell pepper, seeded and cut into strips
    • 6 asparagus spears, sliced on the diagonal into 2” pieces
    • 8 large eggs
    • 8 ounces shredded white cheddar cheese 
    • 1 teaspoon freshly ground black pepper
    • 2 ounces freshly grated Parmigiano-Reggiano cheese
    • Optional garnish: your choice of fresh herbs

    Directions

    Step 1

    Bring a large pot of water to a rapid boil. Add the potatoes and the tablespoon of salt. Boil until the potatoes are tender, about 15 minutes then drain. 

    Step 2

    While the potatoes are boiling, heat a 10-inch cast-iron skillet over medium-high heat. When hot, add 2 tablespoons of olive oil, the onion, bell pepper, asparagus, and 1 teaspoon salt. Sauté until the vegetables are tender then transfer them to a bowl. 

    Step 3

    Preheat your oven to 400°F. Brush the skillet with a tablespoon of olive oil. When the potatoes are cool enough to handle, place them in the skillet. Starting in the center, use a metal measuring cup to flatten them against the bottom of the skillet. Then use the side of the measuring cup to press them halfway up the sides. Check the “crust” to be sure the entire bottom of the skillet is covered. Drizzle the potatoes with the remaining 2 tablespoons of olive oil and sprinkle on 1 teaspoon salt. Place the skillet in the oven and bake for about 30 minutes, until the potatoes are crispy. 

    Step 4

    While the crust is baking, whisk the eggs in a large bowl. Fold in the shredded cheese, vegetables, remaining teaspoon of salt, and black pepper. 

    Step 5

    When the crust in done, transfer the skillet to a heat-resistant pad or trivet. Carefully pour in the egg mixture. Sprinkle the Parmigiano-Reggiano evenly across the top and return the skillet to the oven. Continue baking until the eggs are set, about 20 to 30 minutes, depending on your oven. Let cool for 10 minutes before garnish with herbs, if desired, and cutting into wedges.

    Yields 6 to 8 servings

New Potatoes

New potatoes are early-harvest spuds, just as rich in vitamin B6 and potassium as more mature ones but sweeter. Their thin, tender skins don’t need to be peeled, but they’re also more delicate—buy only what you’ll use within a week or two at most, and store in a paper bag in the fridge. Wash just before using, but don’t scrub or you risk wearing away the nutrient-rich skin. These potatoes also cook up fast. When drizzled with olive oil and roasted, the skins crisp up while the flesh becomes creamy—heavenly!

Sizing Up Cast-Iron Skillets

Variety of skillet sizes

Many chefs love cast iron because of how well it retains heat, resulting in more even cooking. But most people own just one cast-iron skillet, if they own any. And chances are it’s either 10 or 12 inches. So, you might be surprised to learn that they come as small as 3-1/2 inches—great for making one perfect fried egg—and as large as 17 inches, and sometimes more. Another thing that might come as a surprise is that these pans can be either smooth or rough surfaced. Smooth surfaces are better for cooking delicate foods, like a fish fillet, without sticking. They’re also more expensive because of the manufacturing process needed to create that smoothness.

More Reasons to Boost Plant-Based Proteins

A global study published in Nature Communications by experts at the University of Sydney has shown that people around the world who consume more plant-based proteins, such as chickpeas, tofu, and peas, have longer life expectancies. Alistair Senior, PhD, PhD candidate Caitlin Andrews, and their team at the Charles Perkins Centre studied food supply and demographic data between 1961 and 2018 from 101 countries to understand whether the type of protein consumed had an impact on longevity.

Said Andrews, “Our study suggests a mixed picture when it comes to comparing the health impacts of meat- [and] plant-based protein at a population level. For the under-5s, a food system that supplies large amounts of animal-based proteins and fats, such as meat, eggs, and dairy, lowered rates of infant mortality. However, for adults, the reverse was true, where plant-based proteins increased overall life expectancy.”

To understand the impact of plant- and animal-based protein diets on human longevity, the researchers analyzed publicly available data about the food supply across a 60-year period. The data included the amount of food produced per country, along with the levels of calories, proteins, and fats. The countries studied represented a range of food systems, including those where the consumption of animal-based protein is higher, such as Australia, the US, Sweden, and Argentina, and those where the consumption of plant-based foods is more prevalent, such as Pakistan and Indonesia.

To compare the impact of different countries’ food supplies on life expectancy, the researchers corrected the data to account for differences in wealth and population size between countries. They then found that countries where the overall availability of plant-based proteins was higher, such as India, people had relatively longer life expectancies than countries where animal-based proteins were more readily available, such as in the US.

Eating high levels of animal-based protein, particularly processed meat, has long been linked to a range of chronic conditions such as cardiovascular disease, type 2 diabetes, and certain types of cancer. Plant proteins, including legumes, nuts, and whole grains, are associated with a lower risk of chronic diseases and overall mortality rates, with studies suggesting that plant-based diets have contributed to longevity in the most long-lived communities on the planet, such as Okinawa, Japan; Ikaria Greece; and Loma Linda, California.

“Protein is a crucial part of the human diet, but as eating habits change and developed countries look to decarbonize, where we get our protein from has come under greater scrutiny,” said Dr. Senior. “The knowledge that plant-based protein is associated with a longer life is really important as we consider not only how our diets impact our own longevity, but the health of the planet.”

Easing Concerns About Soreness After Activity

Healthy seniors doing yogo and high-fiving

A study done by researchers from multiple institutions in the UK, published in the Journal of Aging and Physical Activity, has overturned the widespread belief that aging muscles are less resilient; they found that older adults experience less muscle soreness than their younger counterparts. 

The research provided a comprehensive analysis of how aging affects muscle function, soreness, and biochemical markers of muscle damage after exercise. By pooling data from 36 studies, the scientists found that older adults do not experience greater muscle function loss after exercise than younger individuals. Younger adults were categorized as between 18 and 25 years old and older adults more than 35 years old. 

The findings suggest that, despite physiological changes with age, muscle resilience remains relatively stable, allowing older people to continue engaging in regular physical activity without increased concern for prolonged weakness or loss of function.

One striking discovery was that muscle soreness was consistently lower in older adults, around 34 percent at 48 hours and 62 percent at 72 hours, compared with soreness in younger individuals. Creatine kinase level, an indicator of muscle damage, was approximately 28 percent lower in older adults at 24 hours post-exercise.

Interestingly, sex appeared to play a role in muscle function recovery, with males showing slightly greater decreases in muscle function after exercise than females. There was no observed impact of upper- or lower-body or exercise type (resistance training or endurance training) on muscle damage markers.

“These findings are significant because they challenge the widespread belief that aging muscles recover more slowly or are more prone to exercise-induced damage. This misconception often discourages older adults from engaging in regular physical activity due to fears of prolonged soreness or weakness,” said senior author Lawrence Hayes, PhD, of Lancaster University Medical School.

If older individuals experience less muscle damage symptoms than previously thought, recovery strategies, training programs, and post-exercise care could be adjusted accordingly. For example, older adults may not require significantly prolonged recovery periods compared with younger individuals, potentially allowing for more frequent or intense training sessions, leading to better long-term health outcomes.

Overall, this study reinforces the importance of staying active throughout life and dispels myths that aging equates to frailty or impaired recovery. These findings could contribute to greater participation in fitness activities among older adults, improving overall health, mobility, and quality of life.

“This means exercise has no age limit, so move more to live longer and healthier,” Dr. Hayes said. “Aim for 150 minutes of activity each week, add strength training twice per week, and most importantly, find a workout you love. When you enjoy it, you’re more likely to stick with it.”

Muffaletta-Style Olive Salad Recipe, Spotlight on Anchovies, Roasting Bell Peppers, Napping: A Sleep-Cycle Foe and Walk This Way

One of the classic New Orleans specialties, muffaletta, is a delectable mix of meats and cheeses served on crusty bread. But its uniqueness comes from the olive salad that fills the hollowed-out top half of the loaf. I always make more than I need because it’s such a tasty condiment, as well as a great topping for grilled bread slices, a wonderful dressing for green salads, and a “sauce” for grilled fish, chicken, and other proteins. 

Most people don’t realize that good sleep is one of the building blocks of health and fitness or that an innocent nap can be a roadblock to restorative ZZZs. Even more important, needing to nap often can be a sign of a health condition. Something else important for wellness is good posture—remember Mom always telling you to stand up straight? Scientists have developed special shoe sensors that may soon help you follow her directive more easily! 

Muffaletta-Style Olive Salad

  • Muffaletta-style olive salad Muffaletta-Style Olive Salad

    This flavorful mix of peppers, olives, and onions defines the muffaletta sandwich—you can choose a mix of your favorite meats and cheeses, like capicola, prosciutto, salami, mozzarella, and provolone, but don’t leave off the olive salad! A batch will stay fresh in the fridge for about a week.

    Ingredients

    • 1 small red onion, peeled and quartered
    • 1 cup pitted kalamata olives
    • 1 cup pitted Castelvetrano olives
    • 2 cups frozen artichoke hearts, thawed
    • 8 Italian hot peppers
    • 1 large red bell pepper, roasted and seeded (see “Quick Kitchen Nugget in weekly newsletter)
    • 6 tablespoons capers, drained
    • 4 anchovy fillets or 1 tablespoon anchovy paste
    • 1 tablespoon dried oregano 
    • 1 teaspoon crushed red pepper flakes
    • 1/4 cup extra virgin olive oil
    • 1/4 cup best-quality red wine vinegar

    Directions

    Step 1

    To the bowl of a large food processor add the onions, olives, and artichokes and pulse until coarsely chopped. Add in the hot peppers, bell pepper, capers, anchovies, oregano, and red pepper flakes and pulse again until finely chopped (don’t let the mixture turn into a paste).

    Step 2

    Transfer to a large bowl and fold in the olive oil and vinegar. Let sit for 30 minutes so that the flavors can meld before using or refrigerating.

    Yields about 4 cups

Healthy Ingredient Spotlight: Anchovies

Healthy Ingredient Spotlight

Anchovies

Anchovies might be the least-appreciated fish among Americans. An essential flavoring agent for dishes such as Caesar salad and puttanesca sauce, anchovies are typically sold here jarred or canned. They’re used in many cuisines, but around the Mediterranean, grilled or breaded fresh anchovies, briny yet mild tasting, are often on the menu. 

It’s the salt curing used to preserve anchovies that intensifies their taste—their saltiness lends depth of flavor to cooked dishes without imparting the full-throated taste of an anchovy eaten right out of the can or jar. Indeed, they quickly dissolve right into the other ingredients. Look for tins of anchovies from Italy. If they are packed in olive oil, drain them well before using.

Roasting Bell Peppers

Grilled bell peppers

Whenever I’ve got my outdoor grill going, I’ll throw on two or three bell peppers, char them well, then peel, deseed, and store them in olive oil in the fridge to use for the coming week. When you need a roasted pepper without turning on the grill, the oven is the way to go. Here’s how.

Preheat your oven to 400°F. Grab a rimmed sheet pan and line it with high-heat parchment paper (it will be marked as safe to use up to 400°F or higher). Place one or more bell peppers on their sides and lightly drizzle with olive oil. Roast for 20 minutes, flip, and roast for another 20 minutes, or until the skin chars and wrinkles. Take them out of the oven and, with your oven mitts still on, fold up the parchment to make a packet that seals in the peppers. This creates steam, which will make it easy to peel off the skins. Wait 15 minutes, then unwrap the parchment and remove the skins. Transfer the peppers to a cutting board, halve them, cut out the stems, and use a spoon to remove the seeds.

Napping: A Sleep-Cycle Foe

Woman napping in hammock

According to a Pew Research Center survey, about 30% of American adults take one or more naps per week, with more than 50% of adults age 80 and older reporting that they had napped in the past day. Among every other age group in the survey, including both young people ages 18 to 29 and older people ages 70 to 79, about a third said they napped in the past 24 hours.

But is all the snoozing good for you? Maria V. Suurna, MD, professor of clinical otolaryngology at the University of Miami Miller School of Medicine and director of sleep surgery at UHealth, the University of Miami Health System, set the record straight on the pros and cons of napping.

“Short naps of no more than 30 minutes during the day can help restore alertness and productivity, making you feel more awake. It’s similar to the effect of drinking a cup of coffee. There’s nothing wrong with taking a nap, but it’s important not to make it too long. It may be helpful to set an alarm for 30 minutes, especially if it’s late in the afternoon, to avoid interfering with your nighttime sleep,” said Dr. Suurna. “If you have trouble sleeping at night, it’s generally not recommended to nap during the day, as it can make it harder to fall asleep and get a full 7-9 hours of sleep at night. 

“If you feel excessively sleepy during the day, often falling asleep during meetings or, more dangerously, while driving, it’s important to consult a sleep doctor. Needing to take multiple naps throughout the day could be a sign of sleep problems such as sleep apnea, hypersomnolence, or other sleep disorders. A medical evaluation can help identify and address any underlying issues,” she added.

As a reminder, you may be able to boost nighttime sleep quality with these good sleep habits: 

  • Review your medications with your doctor, as some may have sedating side effects while others may act as stimulants, making it harder to stay asleep. 
  • Go to bed and wake up at the same time every day.
  • Avoid electronics, TV, and other screens starting at least 30 minutes before bedtime.
  • Reduce exposure to bright lights in the evening.
  • Keep your bedroom cool, dark, and quiet.
  • Avoid alcohol and caffeine starting in the early afternoon, as they can interfere with sleep quality and contribute to insomnia.

Walk This Way

A new smart insole system that monitors how people walk in real time could help improve posture and provide early warnings for conditions from plantar fasciitis to Parkinson’s disease, according to a study published in the journal Science Advances. Constructed using 22 small pressure sensors and fueled by small solar panels on the tops of shoes, the system offers real-time health tracking based on how a person walks, which is a biomechanical process as unique as a human fingerprint.

This data can then be transmitted via Bluetooth to a smartphone for a quick and detailed analysis, said Jinghua Li, PhD, co-author of the study and an assistant professor of materials science and engineering at The Ohio State University. “Our bodies carry lots of useful information that we’re not even aware of,” said Dr. Li. “These statuses also change over time, so it’s our goal to use electronics to extract and decode those signals to encourage better self-healthcare checks.”

It’s estimated that at least 7% of Americans suffer from ambulatory difficulties, often having a hard time with basic activities that include walking, running, and climbing stairs. While efforts to manufacture a wearable insole-based pressure system have risen in popularity in recent years, many previous prototypes were met with energy limitations and unstable performances. To overcome the challenges of their precursors, Dr. Li and Qi Wang, the lead author of the study and a current PhD candidate at Ohio State, sought to ensure that their wearable is durable, has a high degree of precision when collecting and analyzing data, and can provide consistent and reliable power. 

“Our device is innovative in terms of high resolution, spatial sensing, self-powering capability, and its ability to combine with machine learning algorithms,” she said. “So, we feel like this research can go further based on the pioneering successes of this field.”

Their system is also unique because of its use of AI. Thanks to an advanced machine learning model, the wearable can recognize eight different motion states, from static ones like sitting and standing to more dynamic movements such as running and squatting. Since the materials used for the insoles are flexible and safe, the device, much like a smartwatch, is low risk and appropriate for continuous use. For instance, after the solar cells convert sunlight to energy, that power is stored in tiny lithium batteries that don’t harm the user or affect daily activities.

Because of the distribution of sensors from toe to heel, the researchers could see how the pressure on parts of the foot is different in activities such as walking versus running. During walking, pressure is applied sequentially from the heel to the toes, whereas during running, almost all sensors are subjected to pressure simultaneously. In addition, during walking, the pressure application time accounts for about half of the total time, while during running, it accounts for only about a quarter.

The smart insoles could support gait analysis to detect early abnormalities associated with foot pressure-related conditions like diabetic foot ulcers, musculoskeletal disorders such as plantar fasciitis, and neurological conditions such as Parkinson’s disease.

Because the system uses machine learning to learn and classify different types of motion, it offers opportunities for personalized health management, including real-time posture correction, injury prevention, and rehabilitation monitoring. Customized fitness training may also be a future use, the researchers said. “The interface is flexible and quite thin, so even during repetitive deformation, it can remain functional,” said Dr. Li. “The combination of the software and hardware means it isn’t as limited.”

Researchers expect the technology will likely be available commercially within the next three to five years. Next steps to advance the work will be aimed at improving the system’s gesture recognition abilities, which, according to Dr. Li, will likely be helped with further testing on more diverse populations. “We have so many variations among individuals, so demonstrating and training these fantastic capabilities on different populations is something we need to give further attention to,” she said.

Whole Roasted Cauliflower with Pea Pesto Recipe, Spotlight on Cauliflower, Time-restricted Eating and Exercise, plus Exercise to Fight Mental Fatigue

Perfect for spring, this week’s recipe brings together the goodness of superfood cauliflower and the freshness of pea pesto. It’s a side dish satisfying enough for a main course. Next, I’m sharing two studies with the value of exercise at their core—why exercise is a smart adjunct to time-restricted eating and how it can help you feel less mentally exhausted by challenging tasks.

Whole Roasted Cauliflower with Pea Pesto

  • Whole roasted cauliflower with pea pesto Whole Roasted Cauliflower with Pea Pesto

    This dish gets a double dose of flavor from the cheesy crust on the cauliflower and the pesto sauce. 

    Ingredients

    For the cauliflower:

    • 1 head cauliflower, about 2 pounds
    • 4 tablespoons extra virgin olive oil, divided use, plus more for drizzling
    • 2 garlic cloves 
    • 1/4 cup finely minced fresh herbs or 1 teaspoon dried herb mix
    • 1 teaspoon fine sea salt
    • 1/2 teaspoon fresh ground black pepper
    • 1/3 cup finely grated Parmigiano-Reggiano cheese

    For the pea pesto: 

    • 10 fresh basil leaves
    • 4 ounces shelled green peas
    • 2 garlic cloves
    • 1/4 cup freshly grated Parmigiano-Reggiano cheese
    • 1-1/2 ounces shelled walnuts
    • 1/4 cup extra virgin olive oil
    • 1/4 cup cold water
    • Coarse sea salt and freshly ground black pepper, to taste

    Directions

    Step 1

    Preheat your oven to 400°F. Drizzle 1 tablespoon olive oil in a Dutch oven or baking dish large enough to hold the cauliflower; set aside.

    Step 2

    Peel off the outer leaves of the cauliflower and trim the core just enough for the cauliflower to sit flat. 

    Step 3

    Place the remaining olive oil in a small bowl and use a microplane grater to grate the garlic cloves into it. Add the herbs, salt, and pepper and whisk well. Brush the mixture over the cauliflower, then press on the cheese. Cover the Dutch oven or baking dish and roast for 40 minutes. Carefully uncover and roast for another 15 minutes to lightly brown the crust.

    Step 4

    While the cauliflower is roasting,make the pea pesto: Place the basil, peas, garlic, cheese, and walnuts in a food processor and pulse until very finely minced. With the machine running, add the olive oil and process until smooth. Add the water and pulse a few times. Season to taste with salt and pepper if needed. 

    Step 5

    To serve, cut the cauliflower into wedges, plate, and drizzle with the pea pesto and a few drops of olive oil.

the Iowa State University Extension. Over time, white cauliflower evolved thanks to selective breeding and became the norm. (White cauliflower stays creamy white if not exposed to direct sunlight.) So the return to cauliflower of different hues, while again a result of selective breeding, is actually cauliflower getting back to its roots.

With a difference in color comes a (slight) difference in nutrients. Purple cauliflower gets its shade from anthocyanin, the naturally occurring phytochemical that also gives bright red, blue, or purple fruits and vegetables their rich colors. By contrast, orange cauliflower gets its hue from the same carotenoids that are in orange and yellow fruits and vegetables. Green cauliflower, a hybrid of broccoli and cauliflower, has beta carotene, though not as much as pure broccoli.

All shades of cauliflower can be eaten raw or cooked.

Cauliflower Prep 

This vegetable needs only minimal prep. Roasting a whole head just involves removing the outer leaves and trimming the core flush with the base of the head. It can be drizzled with any marinade you like and then sliced into wedges or steaks after cooking. 

You can cut a raw head into steaks if your prep calls for it, but keep the core intact for slicing, then use a sharp paring knife to cut out the core from each steak—you’ll lose fewer florets this way.

If you want to make florets for a dish, turn the cauliflower on its head and use a paring knife to cut pieces away from the stem, rotating the head as you go. Halve or quarter any large florets as needed.

Time-restricted Eating and Exercise 

Time-restricted eating—eating within a set number of hours—is an approach that many use to try to lose weight. One concern when dieting is how to lose fat while protecting muscle. A study from the University of Mississippi, published in the International Journal of Obesity, showed that when healthy adults paired an eight-hour eating window with regular exercise for at least four weeks, they lost more fat without sacrificing lean muscle compared to exercise alone. That lean mass preservation is key, Said Nadeeja Wijayatunga, MD, PhD, RDN, assistant professor of nutrition and hospitality management. 

Dr. Wijayatunga and tactical dietitian Michael Hays, PhD, RD, CSCS, began their study after seeing the dramatic rise in time-restricted eating. Together, they conducted a systematic review and meta-analysis of 15 studies on time-restricted eating with exercise from the past decade. “People like time-restricted eating because they feel it’s easier to adhere to…they don’t have to think too much,” said Dr. Wijayatunga. “It’s all about time, not calorie-counting or watching out for certain foods.”

According to the 2023 International Food and Health Survey, 12% of Americans have tried time-restricted eating, but the science surrounding it is still developing, Dr. Hays said. “For some people, this may be a good technique to help with body composition goals. It’s just another tool, but more studies need to come out to really understand how this works in humans.”

While the difference between those who exercised while following a time-restricted diet and those who used exercise alone was slight, the individuals in the two groups in the studies were very healthy. “They were already physically fit and already had exercise routines. When you already have athletic, lean people and you decrease their body fat percentage, that’s significant,” explained Dr. Hays.

Time-restricted eating has been criticized for possibly leading to a loss of lean mass—all the muscles, organs, and other tissues that make up the human body. “We need healthy muscles,” Dr. Wijayatunga said. “Muscles are really important for the body and for your metabolism. If we lose muscle, it may impact our metabolic systems, and it just decreases mobility overall.”

“That’s why you want to couple diet with exercise,” Dr. Hays adds. “When you’re losing weight, you never want to lose lean tissue. You want to lose fat.”

While the results are promising, Dr. Wijayatunga warned that more research is needed to confirm the findings and to learn how this would impact people who are not in shape and/or not exercising regularly. “What I’d recommend is implementing healthy habits in a way that you, as an individual, can maintain with guidance from a healthcare professional.”

Exercise to Fight Mental Fatigue

Ever feel mentally fatigued after a challenging task? It can happen later in life, even if you’re retired. Researchers from the University of Birmingham in the UK and the University of Extremadura in Spain have found that older people who exercise regularly are more able to fight the impacts of mental fatigue. Their study, published in the Journal of Aging and Physical Activity, looked at whether age increased and regular exercise decreased the impact of mental fatigue on a series of cognitive and physical performance tests.

In the first study, sedentary men ages 65 to 79 performed worse in tests than those 52 to 64, and these impairments were greater when they were tested in a state of mental fatigue. A second study with retired men and women ages 66 to 72 found that performance when mentally rested or fatigued was better in the physically active older adults than in their sedentary peers.

Chris Ring, PhD, professor of psychology at the University of Birmingham and corresponding author of the study, said, “This study shows how important physical activity is for adults as they get older and in general for avoiding the worst impacts of mental fatigue on cognitive and physical performance. This research from our ongoing international collaborative venture confirms that regular physical activity has a host of benefits, with increased physical fitness associated with improved cognition, increased exercise capacity, and greater mental fatigue resilience. For older adults in particular, regular exercise represents a simple but effective means to stave off the effects of age in a host of areas, including avoiding the negative effects of feeling mental fatigued after a particularly taxing task.”

Dr. Ring suggested that the following three active steps can be taken by older adults wishing to perform better in demanding situations:

  • First, increase your level of regular physical activity.
  • Second, warm up using a combination of cognitive and physical tasks to better prepare for an upcoming physical performance, especially when feeling mentally fatigued.
  • Third, train using a combination of cognitive and physical tasks, a method called Brain Endurance Training, or BET, to improve mental fatigue resilience and enhance physical performance.
