Hepatitis C

Dangers of Processed Foods
Many processed foods are full of sugar and salt that raise blood pressure, increasing risk for heart attacks, strokes, and premature death. Most dietary salt does not come from the salt shaker and most dietary sugar does not come from the sugar bowl.
Placebos to Race Faster
Fifteen endurance-trained runners, average age 27, ran three kilometers (1.8 miles) 1.2% faster after injecting themselves with a placebo than they did after taking no injections (Med Sci Sports Exerc, published online Nov 19, 2014). The runners were initially...
Predict Your Heart Attack Risk
Heart attacks are usually caused by an unhealthful lifestyle and are prevented far more effectively by lifestyle changes than by drugs. A healthful lifestyle can prevent more than 80 percent of heart attacks
Weight Loss with Intermittent Fasting
Eating regular meals five days a week and markedly reducing calories for the other two days may be the best way to lose weight and keep it off. This approach to weight loss is called “intermittent fasting.” We have some good data on how effective this diet regimen is for animals, but we are just starting to see the results of research on humans. Most of the studies on humans do not ask participants to avoid all food on their “fast” days.

Sunscreens Only Partially Block the Sun’s Rays
Sunscreens offer only partial protection from the sun. It is dangerous to expose large areas of your sun screen-coated skin to sunlight. If you want to really protect your skin from sun damage, get under a roof when the sun is out in full force. Clothes are next best, and sunscreens are a poor third.
Sodas with Sugar May Age Cells
Researchers led by Elizabeth Blackburn, PhD, winner of the 2009 Nobel Prize in Physiology or Medicine for telomere-related discoveries, measured the telomeres in white blood cells of 5,309 participants, ages 20 to 65, with no history of diabetes or heart attacks. They found that people who drink sugared sodas daily have shorter telomeres than those who drink fruit juices or artificially sweetened drinks
More Mitochondria for Better Athletes?
The huge number of mitochondria in dogs’ muscles explains why sled dogs can run more than 100 miles a day, at sub-8-minute-mile pace for weeks on end, while humans could not possibly run as long or as fast and recover from such abuse of their muscles.
