How many push-ups can you do in a minute? The number may predict your risk of heart disease, suggests a study published online Feb. 15, 2019, by JAMA Network Open.

Harvard researchers analyzed data from 1,104 healthy firefighters, average age 40, who did not have cardiovascular disease. Each man performed as many push-ups as possible in one minute. The men also had treadmill tests to measure their cardiovascular health and aerobic fitness. After 10 years, the researchers found that the men who had originally performed the most push-ups were least likely to get heart disease.

Need another reason to monitor your intake of ultra-processed foods? Cutting down on your amounts could help you live longer.

In an observational study published online Feb. 11, 2019, by JAMA Internal Medicine, almost 45,000 adults ages 45 and older completed several dietary assessments over a two-year period. On average, ultra-processed foods made up about 15% of their daily diet as measured in grams.

Fried foods linked to earlier death

Updated May 1, 2019

Healthier options, such as baking, can offer similar taste without the health drawbacks.

Fried foods are crunchy, crispy, and tasty, but as tempting as they are, eating them too often might shave years off your life.

A study published online January 23 by The BMJ found that women who ate one or more servings of fried chicken daily were 13% more likely to die prematurely from any cause and 12% more likely to die from heart-related causes than women who didn't eat any fried food.

Chronic inflammation may put your brain at risk

Updated May 1, 2019

Research we're watching

Not only might chronic inflammation affect your heart health, but it could also lead to cognitive decline, according to a study published in the February issue of Neurology. Researchers measured inflammation in more than 12,000 middle-aged adults, assigning each a composite score using four inflammation-related biomarkers found in the blood. They then assessed the cognitive function of the participants in three separate visits over the next 20 years. They found that after adjusting for demographic and other variables, inflammation appeared to be associated with increased cognitive decline. People in the study who had higher inflammation scores experienced 7.8% greater cognitive decline when compared with study participants who had lower scores.

Even brief periods of movement can reverse the harmful effects of sitting

Updated May 1, 2019

Research we're watching

You've probably heard that it's harmful to your health to spend too much time sitting around. But a study published January 14 in the American Journal of Epidemiology shows that it may be possible to reverse some of that harm by engaging in short periods of movement throughout the day.

Researchers recruited 8,000 people ages 45 and older and asked them to wear an activity monitor for a week. The device tracked them throughout the day to see how much they sat and how much they moved.
