Burrata and Stone Fruit Salad Recipe, Spotlight on Plums, Storing Stone Fruit, Is Black Coffee the Secret to a Longer Life, and Matching Workouts to Your Personality

’Tis the season … for stone fruit, that is. Nature’s bounty of plums, apricots, and peaches is at its height in late summer, and a composed salad is a fantastic way to enjoy them—no cooking required! Love your morning joe? I’m sharing new insights into its health benefits and why, in order to reap benefits from exercise, it’s so important to focus on activities you truly enjoy.

Burrata and Stone Fruit Salad

• Burrata and Stone Fruit Salad

  This dish is delicious any time of day—from breakfast to dessert. I love to mix different varieties of the same fruit, such as yellow, red, and purple plums, and white and yellow peaches, but most important is to buy local for the sweetest, freshest fruits.

  Ingredients

  For the dressing:

  • 2 tablespoons extra virgin olive oil
  • 2 tablespoons honey, preferably a variety local to your area
  • 1 tablespoon balsamic vinegar of Modena

  For the salad:

  • 2 plums
  • 2 peaches
  • 4 apricots
  • 1/4 lemon 
  • 1 fresh burrata
  • Fresh thyme, oregano, or basil leaves
  • Black pepper

  Directions

  Step 1

  Make the dressing by whisking together the oil, honey, and balsamic; set aside.

  Step 2

  For the salad, halve the fruit, remove the pits (the “stones”), and slice into wedges. Place in a large bowl and squeeze on the juice from the lemon.

  Step 3

  To compose the salad, cut the burrata in half and center a half on each of two plates. Arrange the fruit around the cheese and drizzle with the dressing. Top with fresh herbs and a few twists of black pepper from your grinder.

Plums

Rich in antioxidants thanks to their high flavonoid content, plums deserve a place on your fruit list, and with dozens of varieties available, you can have fun hunting for the ones you like best. Of course, the deeper the color—which comes from its anthocyanins, a type of flavonoid—the more benefits you’ll reap. Plums are anti-inflammatory, have a respectable amount of fiber, and may even help keep blood sugar levels on an even keel. Eating dried plums, AKA prunes, has been linked to better bone health, too. Just avoid those with added sugar and limit quantities since they’re high in calories.

Storing Stone Fruit

Peaches, plums, and apricots can be stored at room temperature until ripe. If you’re not yet ready to eat them, move them to the fridge—that buys you a few days, though they may not taste as sweet. An ideal vessel is an empty egg carton (paper, not plastic or foam) because it offers cushioning to avoid bruising and moisture absorption to avoid mold.

Is Black Coffee the Secret to a Longer Life?

Coffee might be doing more than fueling your morning routine—it could be extending your life. But here’s the catch: The benefits drop when sugar and saturated fats like cream are added in excess.

In a new observational study, published online in The Journal of Nutrition, researchers from the Gerald J. and Dorothy R. Friedman School of Nutrition Science and Policy at Tufts University found that having one to two cups of caffeinated coffee per day was linked to a lower risk of death from all causes and death from cardiovascular disease, but that the benefits dropped depending on what was added to it.

Black coffee and coffee with low levels of added sugar and saturated fat were associated with a 14% lower risk of all-cause mortality as compared to no coffee consumption. The same link was not observed for coffee with high amounts of added sugar and saturated fat.

“Coffee is among the most-consumed beverages in the world and, with nearly half of American adults reporting drinking at least one cup per day, it’s important for us to know what it might mean for health,” said Fang Fang Zhang, PhD, senior author of the study and the Neely Family Professor at the Friedman School. “The health benefits of coffee might be attributable to its bioactive compounds, but our results suggest that the addition of sugar and saturated fat may reduce the mortality benefits.”

The study analyzed data from nine consecutive cycles of the National Health and Nutrition Examination Survey from 1999 to 2018, linked to National Death Index Mortality Data. The study included a nationally representative sample of 46,000 adults aged 20 years and older who completed valid first-day 24-hour dietary recalls. Coffee consumption was categorized by type (caffeinated or decaffeinated), sugar, and saturated fat content. Mortality outcomes included all-cause, cancer, and cardiovascular disease. Low added sugar (from granulated sugar, honey, and syrup) was defined as under 5% of the Daily Value, which is 2.5 grams per 8-ounce cup or approximately half a teaspoon of sugar. Low saturated fat (from milk, cream, and half-and-half) was defined as 5% of the Daily Value, or 1 gram per 8-ounce cup or the equivalent of 5 tablespoons of 2% milk, 1 tablespoon of light cream, or 1 tablespoon of half-and-half.

In the study, consumption of at least one cup per day was associated with a 16% lower risk of all-cause mortality. At two to three cups per day, the link rose to 17%. Consumption beyond three cups per day was not associated with additional reductions, and the link between coffee and a lower risk of death by cardiovascular disease weakened when coffee consumption was more than three cups per day. No significant associations were seen between coffee consumption and cancer mortality.

“Few studies have examined how coffee additives could impact the link between coffee consumption and mortality risk, and our study is among the first to quantify how much sweetener and saturated fat are being added,” said first author Bingjie Zhou, a recent PhD graduate from the nutrition epidemiology and data science program at the Friedman School. “Our results align with the Dietary Guidelines for Americans, which recommend limiting added sugar and saturated fat.”

Limitations of the study include the fact that self-reported recall data is subject to measurement error due to day-to-day variations in food intake. The lack of significant associations between decaffeinated coffee and all-cause mortality could be due to low consumption among the population studied.

Matching Workouts to Your Personality 

According to researchers at University College London (UCL), the key to sticking with and reaping the rewards of exercise over the long term, like boosting fitness and slashing stress, may be as simple as doing activities you enjoy and that align with your personality.

Previous research showed that the personalities of people who engage in different types of organized sport tend to vary. But what was less clear was how personality affects the types of exercise people actually enjoy doing. The new study, published in Frontiers in Psychology, explored whether individual personality traits corresponded to the enjoyment of different types of exercise, whether participants completed a prescribed exercise program, and the subsequent impact on their fitness levels.

Flaminia Ronca, PhD, associate professor at the UCL Institute of Sport, Exercise, and Health, and first author of the study, said, “We know that the global population is becoming increasingly sedentary. You often hear about people trying to become more active but struggling to make lasting changes. In this study, we wanted to understand how personality can influence this to support the development of effective interventions for changes in health behavior. We found some clear links between personality traits and the type of exercise the participants enjoyed most, which I think is important because we could potentially use this knowledge to tailor physical activity recommendations to the individual and hopefully help them to become and remain more active.”

For the study, the team assessed 132 volunteers from the general public with a range of fitness levels and backgrounds, who were assigned either to an 8-week cycling and strength training program (the intervention group) or to a resting control group. There were three weekly cycling sessions that varied in intensity: a 60-minute light ride at an easy pace, a 30-minute threshold ride at a moderate but sustainable effort, or high-intensity interval training (HIIT) where the level of exertion varied.

Participants’ benchmark fitness levels were assessed at the beginning of the program. Strength was tested using press-ups, performing a plank to failure, and countermovement jumps (jumping again immediately after landing). This was followed by a low-intensity cycling session for 30 minutes, then a cycling test to measure peak oxygen capacity (V̇O₂ max test) after a short rest.

The team also assessed participants’ perceived stress levels on a scale of 1 to 10, as well as their personality traits using the Big 5 model, a common personality test in the field of sport and exercise psychology that groups people according to whether their dominant trait is extroversion, agreeableness, conscientiousness, neuroticism, or openness. During the exercise program, participants were asked to rate their enjoyment of each exercise session. 

Their fitness level was tested again once the program had been completed. Of the 132 starters, 86 people completed the intervention and all of these participants got fitter and stronger regardless of personality. While not all personality traits had a link to exercise enjoyment, several connections were uncovered by the study:

• Extroverts tended to particularly enjoy high-intensity exercise, such as HIIT and a fitness test of maximum-intensity cycling.

• Those with a strong neuroticism trait engaged well with the exercise intervention but preferred bursts of intensity rather than prolonged intensity. They also preferred not being monitored, such as not having their heart rate recorded while undertaking the program, suggesting that these individuals might appreciate being given space for independence and privacy when engaging in exercise.

• Those who were conscientious tended to have a well-rounded fitness level, meaning that they tended to score more highly on aerobic fitness as well as core strength, and were generally more physically active. However, conscientiousness didn’t predict higher enjoyment of a specific form of exercise. The authors said this might be because conscientious individuals tend to be driven by the health-related outcomes of engaging in physical activity rather than enjoyment, suggesting that adherence to the program may be less about enjoyment than because it was good for them.

At the beginning of the study, the stress levels of the intervention group and the control group were similar. However, the only group to experience a significant reduction in stress levels after exercising were those who scored highly in the neuroticism trait. “This suggests that there may be particular benefits in stress reduction for those with this trait,” said Professor Paul Burgess, PhD, professor of cognitive neuroscience and an author of the study.

The researchers concluded that the most important thing people can do to improve their activity levels is to find something that they enjoy, which will make it more likely that they’ll stick with it.

Tropical Shrimp Salad Recipe, Spotlight on Shrimp, Choosing and Deveining Shrimp, Fasting to Manage Type 2 Diabetes, plus Weight Gain Despite Exercise

When it comes to classic warm-weather dishes, shrimp salad is often at the top of the list. But when summer’s heat is raging, the traditional mayo dressing can feel heavy. This recipe pairs shrimp with sweet mango and creamy avocado for a tropical taste sensation. Need to tweak your diet for better diabetes control? A new study compared three top options to uncover the best option, while other research I’m sharing found that too many calories rather than a lack of exercise is what’s behind weight gain.

Tropical Shrimp Salad

• Tropical Shrimp Salad

  This shrimp salad refresh uses a light vinaigrette to bring out the flavors of the shellfish as well as the mango and avocado. For ease, zest the citrus fruits before juicing them.

  Ingredients

  For the vinaigrette:

  • 1 tablespoon orange zest
  • 1/4 cup fresh orange juice
  • 2 tablespoons lime zest
  • 1/4 cup fresh lime juice
  • 2 teaspoons honey
  • 1 teaspoon low-sodium soy sauce
  • 1/4 cup extra virgin olive oil
  • 1 tablespoon finely chopped fresh cilantro or flat-leaf parsley

  For the salad:

  • 1 pound jumbo or extra-large shrimp, preferably wild caught, peeled and deveined if needed
  • 1 large ripe mango, diced
  • 1 large ripe avocado, diced
  • 12 cherry tomatoes, halved
  • 6 cups mixed lettuces such as arugula, radicchio, and green leaf, rough chopped

  Directions

  Step 1

  Boil the shrimp in a large pot of salted water until they turn pink, 3 to 5 minutes; drain and set aside to cool.

  Step 2

  In a small bowl, whisk together the zests, juices, honey, and soy sauce. Keep whisking as you drizzle in the olive oil. Fold in the cilantro or parsley.

  Step 3

  In a large bowl, combine the shrimp, mango, avocado, and tomatoes. Drizzle on half the vinaigrette and toss gently. 

  Step 4

  Divide the lettuces among four plates and top with equal amounts of the shrimp mixture. Pass the rest of the vinaigrette separately.

Choosing Shrimp

According to the National Fisheries Institute, each American eats about 5 pounds of shrimp a year. To meet the demand both here and around the world, many countries, including Indonesia, India, Thailand, and Vietnam, farm shrimp for export, often under conditions that could be unsafe and hard to check on. Farmed shrimp clustered in ponds require antibiotics and chemicals to ward off diseases—they’re not only in these shrimp, but they also leech into waterways, raising concerns for the environment. One positive step forward is recirculating farms, which are in early stages in the US, that raise shrimp in large indoor tanks or under hoop houses.

For a variety of reasons, many people choose wild-caught shrimp over farm-raised. The shrimp may be healthier, but there has been the problem of bycatch—other fish and sea creatures that get caught in shrimp nets. Fortunately, more sophisticated equipment and innovations have reduced bycatch amounts in some waters, especially in the Gulf of Mexico and around Oregon’s pink shrimp fishery.

While there’s no single right answer, you can look for packaging that bears the label of an organization that looks out for consumers. The Marine Stewardship Council or MSC is the main certifier of sustainable wild fisheries, and 36 shrimp fisheries currently carry its blue fish label. The Monterey Bay Aquarium Seafood Watchis a program that provides science-based recommendations about which seafood to buy based on sustainability. 

Also to keep in mind: Whole Foods stores have their own standards for both wild shrimp and farmed shrimp. The company’s standards for farm-raised shrimp ban antibiotics and preservatives and prohibit the conversion of sensitive ecosystems such as mangrove forests into shrimp farms, a practice that has devastated parts of Southeast Asia.

Deveining Shrimp

What looks like a vein running the length of a shrimp’s back is actually its digestive tract. If the shrimp ate before getting caught, the tract can be very noticeable. Though it might be safe albeit gritty to eat, many people like to “devein” their shrimp before cooking. Allow yourself a few minutes: since you’ll be using a sharp knife, you don’t want to rush through the process, which is simple enough.

Once the shrimp is peeled, simply run the tip of a paring knife down the length of its back to expose the digestive tract and then pop it out. Rinse the shrimp under cold water and place it in a colander before moving to the next one.

Fasting to Manage Type 2 Diabetes

A new study from the Endocrine Society is the first to compare three popular diets head-on—intermittent fasting (also known as 5:2 intermittent energy restriction or IER), time-restricted eating (TRE), and calorie cutting (continuous energy restriction or CER). 

Researchers found that all three can help people with type 2 diabetes lose weight and lower blood sugar, but one diet stood out: intermittent fasting. This involves eating normally five days a week and restricting calories on the other two. It led to better results in fasting blood sugar, improving insulin sensitivity, lowering triglycerides, and sticking with the plan.

“The research fills a gap in directly comparing 5:2 intermittent energy restriction with 10-hour time-restricted eating in patients with obesity and type 2 diabetes. The findings provide scientific evidence for clinicians to choose appropriate dietary strategies when treating such patients,” said Haohao Zhang, PhD, chief physician at The First Affiliated Hospital of Zhengzhou University in Zhengzhou, China. 

Dr. Zhang and colleagues performed a single-center, randomized, parallel-controlled trial at the First Affiliated Hospital of Zhengzhou University from November 19, 2021, to November 7, 2024. Ninety patients were randomly assigned to one of the three diet plans, with consistent weekly caloric intake across all groups. A team of nutritionists supervised the 16-week intervention.

At the end of the study, there were no significant differences in HbA1c reduction and weight loss between the IER, TRE, and CER groups. However, the absolute decrease in HbA1c and body weight was greatest in the IER group. The IER group had the highest adherence rate at 85%, followed by the CER group at 84% and the TRE group at 78%. Dr. Zhang said these findings highlight the feasibility and effectiveness of dietary interventions for people who have obesity and type 2 diabetes.

Weight Gain Despite Exercise 

We aren’t moving less—we’re just eating more, according to a Duke University study showing that diet, not laziness, is fueling the obesity epidemic across industrialized nations. Our diet, not our activity level, is what has changed the most. 

“Despite decades of trying to understand the root causes of the obesity crisis in economically developed countries, public health guidance remains stuck with uncertainty as to the relative importance of diet and physical activity. This large, international, collaborative effort allows us to test these competing ideas. It’s clear that changes in diet, not reduced activity, are the main cause of obesity in the US and other developed countries,” said Herman Pontzer, PhD, principal investigator with Duke University’s Pontzer Lab, part of the department of evolutionary anthropology at the Trinity College of Arts & Sciences.

The researchers analyzed thousands of measurements of daily energy expenditure, body fat percentage, and body mass index from adults aged 18 to 60 across 34 populations spanning six continents. The more than 4,200 adults included in the study came from a wide range of lifestyles and economies, including hunter-gatherer, pastoralist, farming, and industrialized populations. To further categorize the level of industrialization, the researchers also integrated data from the United Nations Human Development Index to incorporate measures of lifespan, prosperity, and education.

“While we saw a marginal decrease in size-adjusted total energy expenditure with economic development, differences in total energy expenditure explained only a fraction of the increase in body fat that accompanied development. This suggests that other factors, such as dietary changes, are driving the increases in body fat that we see with increasing economic development,” said Amanda McGrosky, PhD, a Duke postdoctoral alumna and lead investigator for the study, now an assistant professor of biology at Elon University.

The researchers hope the study helps clarify public health messaging and strategies to tackle the obesity crisis and explain that the findings do not mean that efforts to promote physical activity should be minimized. Instead, the data support an emerging consensus that both diet and exercise should be prioritized. “Diet and physical activity should be viewed as essential and complementary, rather than interchangeable,” the study noted. The researchers will next work to identify which aspects of diet in developed countries are most responsible for the rise in obesity.
