Sugar is a carbohydrate that provides the body with energy and has an important role in nutrition. It is found in many healthy whole foods, but it is also abundant in unhealthy processed foods. The problem many people have with sugar is that they consume too much of the refined kind added to many processed food products, and not enough of the natural kind in fruits, vegetables, and grains.

A 2022 study found that people who recover from COVID-19 face significantly higher risks of developing type 2 diabetes than those who had short-term upper respiratory tract infections, which are often caused by other viruses.

Strength training triggers many body reactions that protect people against chronic disease. For example, strengthening muscles helps reduce blood sugar, lower blood pressure, burn calories, and discourage chronic inflammation. Evidence suggests that getting 30 to 60 minutes of weekly strength training leads to the highest amount of health benefits. That's in line with the recommendation from the 2018 Physical Activity Guidelines for Americans. But doctors say any amount of strength training can help health.

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.

Over two decades ago, the Diabetes Prevention Program study showed that type 2 diabetes could be slowed or even prevented in people with early signs of it. Now, a long-term follow-up study focusing on death rates from several causes has produced some surprising results.

A study compared eating a serving of French fries every day for a month to eating a serving of almonds with the same number of calories, and found that levels of some health markers were similar between the two groups — but those numbers don't tell the full story.

In American Indian and Alaska Native tribal communities, poor housing conditions have led to high rates of health problems and disability, underscoring the need for adequate, affordable housing designed for people of all ages and abilities.

Heart attacks occur when a blocked coronary artery prevents blood flow to part of the heart. Cardiac arrest is caused by an electrical misfire that causes the heart to abruptly stop beating.

For people in their 80s and beyond, the advice for preventing and treating heart disease is similar to that for young people, especially with respect to staying physically active. But octogenarians may need to adjust their medication regimens. Low-dose aspirin is not recommended after age 70, and doses of anti-clotting medications may need to be reduced. Some people may also need to dial back their blood pressure medications if they experience side effects such as dizziness.

Moderate-to-vigorous exercise appears to be the best way to boost cardiorespiratory fitness (CRF), which quantifies how well the heart and lungs supply oxygen to the muscles during physical activity. Higher CRF during midlife is linked to a lower risk of conditions closely tied to heart disease (including early signs of atherosclerosis, high blood pressure, and diabetes) later in life.
