Higher Vitamin D Levels Linked To Better Fitness
There’s another reason to make sure you’re getting enough of the sunshine vitamin: High levels of vitamin D in the blood are now linked with better fitness, according to research from the Virginia Commonwealth University School of Medicine. In the study, published in the European Journal of Preventive Cardiology, 20- to 49-year-olds with better vitamin D status also tended to have greater cardiorespiratory fitness, a measure of aerobic fitness often determined by measuring maximal oxygen consumption (VO2max) during exertion.
Something’s Fishy With Fish Oil
Don’t like fish? Well, you might not be able to turn to the supplement aisle to get the same benefits for your heart. A Cochrane report exploring 79 randomized trials of more than 112,000 adults (both with and without heart disease) showed that increasing omega-3 intake, mainly from fish oil pills taken for at least 1 year, did not significantly prevent heart attacks, strokes or deaths in general.
Food, Not Pills
Count this as more proof that we shouldn’t rely on pills and powders to make up for dietary shortfalls.
Belly Fat vs. Vitamin D
Here’s another good reason for people to reduce their Buddha-bellies: improving their vitamin D status. According to data presented at the 2018 European Society of Endocrinology’s annual meeting in Barcelona, Spain, researchers from the Netherlands found that more body fat around adults’ waistline is associated with lower vitamin D levels. Beyond raising the risk of weak bones, poor vitamin D status could set the stage for other health issues, including heart disease and compromised immunity.
Understanding Soy Safety
The growing popularity of soy products in U.S. and European diets has raised considerable controversy. While the soy-rich diets of Asia generate documented health benefits, questions persist about the safety of soy in some products, especially infant formula.
To make sense of this debate, it helps to understand the nature of dietary compounds called phytoestrogens—plant-based compounds whose chemical structure resembles estrogens, the female sex hormones of mammals. Also called isoflavones, phytoestrogens are most prevalent in soybeans and red clover.
Recipe For Health: Raspberry Quinoa Lentil Salad
For years, we’ve heard that eating more dietary fiber delivers a range of health
benefits, from greater weight loss to better blood sugar control to lower cholesterol
levels. Now, scientists increasingly suggest that much of the power of fiber
is due to its impact on the human microbiome—our internal colonies of bacteria.
Eating a wide range of high-fiber foods appears to nourish the microbiome
in our digestive tracts.
Who Is (and Isn’t!) Reading Food Labels
The Nutrition Facts panel displayed on all packaged food can relay critical nutrition information like calorie, sugar and fiber content—but only to those who read the label.
An investigation by the University of Minnesota’s School of Public Health and Medical School found that a mere one-third of adults aged 25–36 report frequent use of the Nutrition Facts label. Women, people with more education and income, those who cook more of their own food, and people who exercise regularly were more likely to examine their food purchases carefully.
Question of the Month

Or do you believe the reported dangers are overblown? Send your responses to Sandy Todd Webster at [email protected]
Caffeine Boosts Performance in Athletes Who Use It Rarely
Caffeine stimulates the central nervous system, allowing athletes of all stripes to complete longer, harder workouts. But new research suggests that people who usually avoid coffee and energy drinks likely benefit the most from caffeine.
Magnesium Boosts Power of Vitamin D
Your clients may believe they’re getting ample vitamin D, but they won’t get the full benefit if their diet lacks magnesium. A study published in the Journal of the American Osteopathic Association found that vitamin D is not properly metabolized when magnesium levels are low. Thus, it remains largely inactive in the body, leaving people vulnerable to disorders related to poor vitamin D status, including weak bones.
Go Fish for Stronger Bones
A trip to the fishmonger can help your bones and your heart. Scientists have long noted a link between eating omega-3 fats in certain fish and improving heart function, but these mega-healthy fats are not a one-hit wonder. Critical Reviews in Food Science and Nutrition published a meta-analysis of previous research (which included 292,657 people)—and reported an inverse relationship between fish consumption and risk of hip fracture. Mechanisms still need to be sussed out, but in the meantime it’s a good idea to work fish into our diets at least twice per week.
Environmental Endocrine Disruptors Partly to Blame for Weight Regain in Women?
Maintaining weight loss is extraordinarily difficult for most people for myriad reasons, some understood and others less so.
In February, PLOS Medicine published results of the first randomized controlled human study looking for connections between weight loss and exposure to synthetic chemicals called perfluoroalkyl substances (PFAS). The researchers found that higher blood levels of PFAS don’t affect weight loss but are associated with greater weight regain, especially in women.
Question of the Month: McDonald’s Makes Kids’ Menus Healthier—Are They Healthy Enough?
A Happy Meals makeover is underway at McDonald’s. As of June, all Happy Meals in the U.S. will contain fewer than 600 calories. By 2022, they will have less than 650 milligrams of salt, and under 10% of calories will come from saturated fats and added sugars. Water is now the default beverage. Cheeseburgers are off the Happy Meal menu, while chicken nuggets and hamburgers are served with fruits, vegetables or a 110-calorie mini-side of fries.
Stuffed Portobello Burgers With Caramelized Onions
Fungi. Ewww. That’s true if it’s fuzz on your loaf of bread or mold in the corners of the gym shower. But mushrooms, redolent of the earth and presenting in a dizzying array of shapes, are fruiting bodies worth cozying up to.
Trending: Sparkling Water
Out with soda and in with . . . sparkling water. Health-conscious Americans looking for a carbonated-beverage fix are in luck as sparkling water takes over store shelves across the country. The sugar-free bubbling water is a great hydration source and is free of artificial sweeteners and other processed ingredients common in diet sodas.
Childhood Obesity Stats Remain Grim
A February study in the journal Pediatrics debunked reports that childhood obesity rates were leveling off or in decline. In fact, the study found that despite substantial efforts to curb the epidemic in recent years, obesity rates have increased for every demographic—especially preschool children and adolescent girls. Moreover, the study cited a substantial rise in severe obesity in children.
Cure For Peanut Allergies On the Horizon
Peanut allergies affect 2% of U.S. children and are the leading cause of death by food allergies. Unlike many of them, peanut allergies are rarely outgrown, and there are currently no treatments. People with peanut allergies must scrutinize everything they eat and keep a lifesaving epinephrine injection pen on hand in case of an accidental exposure.
What Are the Most Nutritious Eggs?
Question: What are the most nutritious eggs? There are so many kinds in the supermarket—brown, white, omega-3, free-range. Are there any differences?
Answer: Egg nutrients include protein, fat, vitamin A and choline. Eggs do have cholesterol, but cholesterol in food has little impact on cholesterol in your blood.
Do different eggs have different nutrition profiles? First of all, there is no nutritional difference between white and brown eggs. Different breeds of chickens simply lay eggs of different colors, from white to brown to green.
Cracking The Nutrition Code On Toddler Drinks
An April study looked at the marketing and promotion of toddler drinks—formulas, milk drinks and other beverages for children aged 9–36 months. The research, published in the journal Preventive Medicine, found that these drinks are heavily marketed to parents, poorly regulated, and nutritionally inferior to whole cow’s milk and a balanced diet. The drinks consist primarily of powdered milk, corn syrup solids or other added caloric sweeteners, plus vegetable oil. They also have more sodium and less protein than cow’s milk.
Summer Reading: Devoured
2016) is the book for you.
Sophie Egan, MPH, RD, food writer and program director at The Culinary Institute of America, takes readers on an eye-opening journey through the American food psyche, examining connections between our eating habits and the values that define our national character—work, freedom and progress. Egan explores why these values enable such an unstable and often unhealthy food culture while, paradoxically, making America’s cuisine really impressive.
