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

President John F. Kennedy: Should Health Records Be Released?

John F. Kennedy was probably the sickest U.S. President ever. He suffered from a disease called Autoimmune Polyglandular Syndrome, which was not described until 1981, 18 years after he was assassinated (Medicine, 1981;60(5):355-62). This disease made him miserable by knocking off his thyroid and adrenal glands, and probably his parathyroid glands also.

If you feel discomfort or pain in the skin of your feet while you are exercising, stop exercising immediately and correct the problem. Continuously rubbing your skin can cause very painful blisters that can break and leave you with open painful areas for many weeks.

Normal Fasting Blood Sugar Does Not Rule Out Diabetes

A new position statement from the International Diabetes Federation says that a blood sugar level greater than 155 mg/dL (8.6 mmol/L) one hour after eating a meal means that a person should immediately be referred to a diabetes prevention center and instructed to follow all the lifestyle rules recommended for diabetics.

Best Times to Brush Your Teeth

Dentists do not agree on whether it is better to brush before or after breakfast. I think you should brush after breakfast, but you should try to wait and brush at least 30 minutes after eating. If that doesn't fit into your schedule, do whatever works best for you. Any brushing is better than no brushing.
