The long-held assumption that light to moderate drinking is good for a person’s heart is likely inaccurate. A new study using sophisticated genetic tools suggests that the risk of high blood pressure and coronary artery disease rise for any quantity of alcohol consumption. The added risk is low when people consume up to a single drink per day but rises exponentially at levels above seven drinks per week. This added risk applies to a first-time diagnosis of heart disease and not to people already diagnosed with a heart problem (who might well face even greater risk).

Unsweetened cocoa powder has variable amounts of health-promoting flavanols, depending on how it is processed. Fruits and vegetables are better sources of these compounds, which may improve blood pressure and blood sugar.

Compared with eating carbohydrates, eating protein—particularly protein from plants— was associated with lower odds of later developing cognitive declines, according to a Harvard study in the January 2022 issue of The American Journal of Clinical Nutrition.

In a study published online Feb. 14, 2022, by the journal Heart, people ages 65 or older who exercised at least 20 minutes per day—especially men ages 70 to 75—had fewer heart attacks and a lower risk of premature death, compared with people who didn’t exercise.

Among people with chronic heartburn, sleeping on the left side appears to help backed-up stomach acid leave the esophagus faster than sleeping on the right side or back, according to a study in the February 2022 issue of The American Journal of Gastroenterology.

Two important types of fat in the body are white fat and brown fat. White fat is located in the chest, abdomen, and upper legs; too much of it constitutes obesity. Its function is to provide insulation against the cold, store fats derived from food, and continually release small amounts of the fats to be converted into energy. Brown fat is found in small amounts in the neck, shoulders, chest, and abdomen. Its main function is to burn the fat it stores, creating heat that keeps the body warm.

Water sports that use oars or paddles are effective forms of exercise with many health benefits. However, the sports may pose health risks, especially after age 60. The sports have a repetitive component to them. Paddling can stress the shoulder tendons. Rowing can lead to low back strains. Neither sport would be a good idea for people with tendinitis at the shoulder, elbow, or wrist; a diagnosed back problem such as a disc injury or spinal stenosis; or a previous back surgery.

When doctors say that it’s okay to take proton-pump inhibitors (PPIs) “on demand” for chronic heartburn, the advice doesn’t apply to everyone. PPIs inhibit the production of stomach acid, which can back up into the esophagus and can cause pain (heartburn) and damage the lining of the esophagus. People with damage to the esophagus often stay on PPIs long-term to prevent further problems. People without damage to the esophagus can take a short course of PPIs as needed.

The ability to function relies on maintaining a core body temperature. In a hot environment, body temperature starts to rise and the body releases heat by sweating or by carrying blood away from the body’s core to the skin surface, where heat leaves the body. But those functions wane in older age. As a result, heat can build up, putting organs at risk for severe damage. To avoid such problems, it helps to stay hydrated; avoid going outside during the peak temperatures of the day; stay inside in an air-conditioned environment; and wear lightweight, light-colored clothing in warm weather.
