Physical Activity Plus Moderate Calorie Reduction Helps Cardiovascular Health

As we age, the aorta (the body’s main artery) gets stiffer. Arterial stiffness is associated with increased risk of cardiovascular events, dementia, and death. Excess body weight tends to accelerate the problem. Aerobic activity may help. A recent trial set out to see if aerobic exercise alone could improve aortic stiffness in older adults with […]

“Metabolically Healthy Obesity” May Not Protect Against Heart Disease

If you are obese but all of your “numbers” are good (blood pressure, cholesterol, triglycerides, blood sugar…), a new study suggests you are still at greater risk for cardiovascular disease (CVD) than a normal-weight person with similar numbers. The study used data from nearly 9,500 adults with an average age of 56 years at the […]
“Net carbs” do not include fiber, since fiber is not digested. Food labels are not required to carry this industry term.

Q. What are “net carbs” and why are they only included on the labels...

A. Judith C. Thalheimer, RD, LDN, managing editor if Tufts Health & Nutrition Letter, answers: “Some carbohydrates—specifically fiber but also, to some extent, sugar alcohols—are not fully broken down by the body, and therefore provide few (if any) calories and cause little or no rise in blood sugar levels. The term net carbs refers to […]
Cut oats have more intact structure to slow blood sugar rise, but rolled oats are also a nutritious, whole grain option.

Q. Why are steel-cut oats preferrable to rolled oats? They can’t be used for...

A. Nicola McKeown, PhD, an associate professor at the Friedman School and whole grain expert, answers: “Nutrition publications (including this one) often recommend oatmeal—and steel-cut oats in particular—as a healthy, whole-grain, breakfast option. “After the inedible husk is removed from an oat grain, the resulting groat (inner kernel) can be cut into smaller pieces or […]
A well-nourished population would have been less severely impacted by COVID-19. Personal and policy changes can help us be better prepared in the future.

COVID-19, Nutrition, and You: Lessons from a Pandemic

The COVID-19 epidemic laid bare some stark realities about nutrition in the United States: our food system is fractured, and the resulting poor nutrition and inequities are major contributors to the devastation caused by this disease. The fact is, the overall severity of COVID-19 cases might have been reduced had there been nationwide access to […]

Top 10 Swaps for Good Health

We asked Tufts experts for one small change they would recommend for the biggest benefits. Here’s what they said: 1. Try Barley, not White Rice … or any whole grain instead of any refined, really. Research shows choosing mostly whole grains and 100 percent whole grain products instead of refined grains is associated with many […]
High triglycerides usually have no symptoms. Make sure you have your blood tested as part of your regular wellness care.

Manage Triglycerides for a Healthy Heart

A recent nationwide survey found that around 35 percent of men and 25 percent of women in the U.S. have high blood triglyceride levels (hypertriglyceridemia). Like high LDL (bad) cholesterol levels, high triglyceride levels are associated with increased risk of heart disease, heart attack, and stroke. Dietary and other lifestyle changes can help keep your […]
Fermented foods appear to be good at nourishing a gut microbiome that may decrease inflammation.

Fermented Foods Can Support Health

The microbes that live in our intestines help break down food, and they create byproducts that can impact the immune system and inflammation. A study recently published in the journal Cell looked at how including dietary fiber and fermented foods in one’s dietary pattern may impact this gut microbiome. The small randomized controlled trial fed […]
Researchers have demonstrated that whole grain intake is linked to better cardiometabolic health.

Switch from Refined Grains to Whole to Improve Cardiometabolic Health

Greater whole grain consumption is known to be associated with lower risk of cardiovascular disease. A recent study by Tufts researchers looked at the impact of refined and whole grain intake on specific intermediate risk factors that might be responsible for that association. These factors include fasting blood glucose levels, waist circumference, systolic blood pressure, […]
Simply counting steps may help you get more of them.

Step Counters and Fitness Trackers May Boost Activity Levels

A study that analyzed data from 38 randomized clinical trials involving over 4,200 participants concluded that activity trackers do improve physical activity levels among adults with cardiometabolic conditions like diabetes and heart disease. Over approximately 15 weeks of follow-up, wearing a pedometer (step counter), fitness tracker, or accelerometer (which records movement) significantly increased the amount […]
