Exercise Preserves Brain Function
People who exercise into later life are smarter than those who do not exercise. To prove that exercise preserves brain function, studies must show that the loss of brain function with aging is not just genetic. Identical twins have exactly the same genes, so a study on twins can yield stronger results to show which environmental factors help to prevent loss of brain function.
Who Gets High Blood Sugar After Meals?
Some foods raise blood sugar far more than others, and a high rise in blood sugar after meals can increase risk for diabetes, heart attacks and premature death. A study from Israel shows that some people develop surprisingly high blood sugar levels after eating foods such as bread, pizza, potato, tomatoes or bananas, while others do not develop the expected rise in blood sugar even after drinking a sugared soft drink or eating a cookie.
Jerry Quarry: Dementia from Head Injuries
Jerry Quarry was one of the toughest fighters who ever lived. He was never world champion, but: • He fought main bouts from 1965 through 1975, a time when there were arguably more good heavyweights than at any other time period. • He was never knocked out in his 66...
Angioplasty’s Questionable Results
Angioplasty may not boost survival for heart disease patients. A 15-year follow-up shows that those who have had angioplasties do not live longer than those who received just medication. This supports other studies that have shown that some angioplasties should not have been done
Good Fats in Nuts
Nuts are a rich source of fat, but the fat in nuts is absorbed very poorly (Am J Clin Nutr, Jan, 2015;101(1):25-33). For example, the fat in almonds is located inside the cells of the almond kernel. Even after prolonged chewing, most of the almond cells remained intact and the fat is still inside the cells. Humans lack the enzymes to break down these cell walls. You have to liberate fat from inside cells to absorb it into your body.
Whole Milk or Skim? Cheese and Yogurt are Better
All types of milk and milk products are high in sugar, unless the milk is fermented to make yogurt or cheese. Skim milk may be more harmful to your health than whole milk because skim milk may have higher levels of a sugar called galactose that causes inflammation.

Low-Carbohydrate, High-Fat Diets for Endurance?
Can athletes improve their performance by following a diet that is low in carbohydrates and high in fat (LCHF)? Several popular sports magazines have carried articles advocating LCHF diets, even though at present there is no data to support this regimen for sports that require speed, including marathon running and long-distance bicycle racing. LCHF diets can slow you down in both training and racing.
Ty Cobb: Anger in Athletes
Ty Cobb was probably the most aggressive baseball player who ever lived. He was better than everyone else at almost every baseball statistic except fielding, for which he still holds the American League record for errors (271) by an outfielder. During his baseball...
Sitting Will Not Harm Vigorous Exercisers
I think that asking people to stand at work, rather than sit, is harmful advice because standing and not moving is no better than sitting and is just going to make you too tired to exercise vigorously when you are not working.
