For Would-Be Soldiers, Healthier Diets Pay Off
Active-duty males involved in the U.S. Army Special Forces Assessment and Selection course who had higher Healthy Eating Index (HEI) scores—used to assess compliance with the U.S. Dietary Guidelines for Americans—performed better on the demanding Army Physical Fitness Test and were up to 75% more likely to be selected for the elite unit than those with the lowest diet-quality scores, according to a study in Medicine & Science in Sports & Exercise.
Plant-Based Foods Curb Chronic Disease
Here’s another good reason to embrace the trend of eating more plants: A cohort study in Nature Communications involving 56,048 adults in Denmark found that people who over a 23-year period habitually consumed moderate to high amounts of foods rich in flavonoids—naturally occurring chemical compounds found predominantly in plant-based foods—were less likely to die from cancer or heart disease.
March 2020 Question of the Month: Is Red Meat No Longer the Enemy?
For years, nutrition and health experts have been telling us to cut back on our intake of red meat. Now, a controversial new analysis says this advice was largely unwarranted.
Weighing In on the Keto Diet
While extremely low-carbohydrate diets like fat-forward keto can aid in short-term weight loss, they have mixed effects on other health markers, according to a scientific statement issued by the National Lipid Association and published in the Journal of Clinical Lipidology.
Why Dentists Don’t Approve of Energy Foods
Sports drinks, energy gels and bars can help athletes keep up the pace, but frequent use may land them in the dental chair. According to a study published in the British Dental Journal, regular consumption of these products is likely a major reason why professional athletes have higher rates of tooth decay than the general public, despite eating a healthy diet overall and practicing good oral hygiene, like twice-daily brushing. The sugar content and acidity of energy products can expedite gum inflammation and tooth decay, leading to poor oral health.
Athletes Have an Appetite for Social Media
Social media platforms like Instagram and Facebook continue to open up new opportunities for athletes to learn about nutrition. Based on a questionnaire administered to 306 athletes, a report in the International Journal of Sports Nutrition and Exercise Metabolism found that 65% of study participants reported using social media to glean nutrition information over the previous 12 months.
Insomnia Linked to Refined Carbs

Hunger on the Mind
British researchers found that hunger can significantly influence the choices we make. For the study, reported in Psychonomic Bulletin & Review, a group of 50 participants answered questions at two separate times, once 2 hours after eating and once after fasting for 10 hours. Participants had the option of immediately receiving a reward (including money) or waiting for a more substantial reward later on.
Another Win for Gluten
People without a gluten-related disorder (for instance, celiac disease or nonceliac gluten sensitivity) did not experience gastrointestinal symptoms like bloating after consuming gluten flour twice daily for 2 weeks, according to a double-blind, randomized controlled study in the journal Gastroenterology. This is more evidence to counteract the belief that eating gluten-free as a lifestyle choice is the healthier way to go.
What’s the Word on Keto for Weight Loss?
Finally! Gone are the days where fats were a 4-letter word. Research has dispelled the myth that a diet rich in energy-dense butter, marbled meats, and nuts can make you, well, fat. Informed eaters are now seeking out formerly forbidden coconut oil, fatty fish, and ALL the avocados.
Americans Are Still Eating a Lousy Diet
Health organizations have given advice on nutritious eating for decades, and yet a diet “report card” published in JAMA shows that American adults are still consuming too many nutritionally poor carbohydrates and more saturated fat than is recommended. The study, conducted by researchers from Tufts and Harvard universities, examined data on food choices recorded between 1999 and 2016 by almost 44,000 participants in the National Health and Nutrition Examination Survey.

Prenatal Nutrition is Lacking
Based on data collected from 1,003 pregnant women between 2001 and 2014, a study in JAMA Network Open suggests that many expectant mothers in the U.S. don’t get enough of some nutrients that are vital for a healthy pregnancy.
The Rise of Orange Corn

Healthy Diet Pays Off for Gut Health

January 2020 Question of the Month: Are Nutrition Supplements a Flop?
Supplements are a multibillion-dollar industry in America, but recent studies continue to call into question their usefulness. In a large analysis of 277 randomized trials, researchers from West Virginia University, Johns Hopkins and elsewhere found no proof that vitamin, mineral and other nutritional supplements could help stave off heart disease or prolong life.
