Does exercise help protect against severe COVID-19?

A study examining data from a large health care provider on more than 48,000 people who had COVID-19 found that those were consistently inactive had a significantly higher risk of hospitalization or death, while those who engaged in more than 10 minutes of activity per week had some protection against severe illness or death, and people who were active for at least 150 minutes per week had the most protection.

Should we track all breakthrough cases of COVID-19?

Despite the effectiveness of the COVID-19 vaccines, a small number of people develop cases even after being fully vaccinated. Most of these "breakthrough" cases are mild or moderate, and the CDC has decided to track only the ones that require hospitalization, which has disadvantages.

The numbers add up for eating your five-a-day of fruits and vegetables

Nutritional guidelines continue to advocate eating five daily servings of fruits and vegetables—the so-called five-a-day. New research found that eating more than this amount does not offer extra benefits, and that a ratio of two servings of fruit and three of vegetables might offer the most health benefits.

Coming out of COVID

As Americans begin to slowly move out of the COVID-19 pandemic, they may face old and new challenges. People should use this transition period to prepare mentally and emotionally for a post-COVID world. Steps include planning how to safely return to social gathering, restarting health habits that have fallen away, and addressing mental health issues.

No equipment necessary

People who are not ready to return to the gym can get an all-around workout at home by using only their body weight. Body-weight exercises are often comparable to using weights and machines, and help people return to fitness after an injury or long layoff. They also can help older adults improve everyday movements. A simple workout might include chair squats, step-ups, and push-ups.

Facts about fiber

Fiber improves digestion and may help lower a person’s risk for heart disease, diabetes, and cancer. But according to the 2020–2025 Dietary Guidelines for Americans, most people meet only half their daily fiber needs. The main reason is not following a basic healthy diet with foods high in fiber. Making small changes in dietary habits and adopting new fiber-rich foods can help people reach their quota.

The weighty issue of weight loss

A majority of adults are now considered overweight or obese. Poor diet and lack of exercise are the main contributors, but age also is a factor. Declining muscle mass means the body burns calories at a slower rate. Changing one’s diet to cut out liquid carbs and eat more whole grains and following a regular exercise routine that includes strength training is the best formula for weight loss.

Why do I bruise so easily?

Noticeable bruises as a person ages are related to the tiny blood vessels in the outer layer of skin becoming more fragile. There is not much people can do about this, but they should see their doctors if bruises resemble red or purple spots, appear only on the lower legs, or become painful.
