Benefits of Sunlight Beyond Vitamin D

Too much sun exposure can cause skin cancers, but getting small amounts of sunlight on your skin for short periods may have some benefits beyond providing vitamin D The problem is that nobody really knows how much sun exposure an individual can tolerate without increasing skin cancer risk.

How to Avoid Skin Cancer

Almost all skin cancers are caused by repeated damage to the DNA in skin cells from excessive exposure to sunlight. Every cell in your body is programmed to live for a limited time and then die. This is called apoptosis. For example, red blood cells live for only around 120 days and then die. A new skin cell starts on the inner bottom layer of your skin and then progressively moves to the outside, where it is sloughed off as dander or dandruff at about 28 days.

What to Eat and Drink for Hot Weather Exercise

When you exercise in hot weather, you don't need special sports drinks or power bars. A review of 46 studies shows that a person can prolong endurance by eating before and during exercise (Scand J Med Sci Sports, 2018 May;28(5):1476-1493). However, even the most elite athletes can get the nutrients they need from ordinary foods, water and salt. Healthy and fit people usually don't need to drink or eat when they exercise at a casual pace for less than two hours.

Ancel Keys and John Yudkin Were Both Right about Meat and Sugar

Ancel Keys was a prolific American scientist who is best known for his early work on heart attack risk factors in the 1950s. His theory was that dietary saturated fats and cholesterol raise blood cholesterol and blood pressure to increase risk for heart attacks.. Also in the 1950s, John Yudkin was the leading spokesman for the theory that sugar and other refined carbohydrates were the main culprits. Yudkin and Keys argued continuously, in journals and at medical meetings, about whether sugar or saturated fats were the prime cause of heart attacks.

Intermittent Fasting and Risk for Heart Disease
