Branched Chain Amino Acids

A study from Sacred Heart University in Fairfield, Connecticut showed that taking branched chain amino acids decreased the amount of muscle damage from exercise in untrained volunteers. Branched chain amino acids are protein building blocks that can be converted easily to sugar by your body. A likely explanation for the advantage shown in this study is that muscles become damaged when they run out of their stored sugar and start to burn protein in the muscles themselves for energy.

However, it makes no sense to spend a lot of money on these expensive protein supplements. You will get the same benefit from any food that contains protein. Eat some cheese, seafood, peanut butter, chicken, nuts or any other convenient source of protein when you exercise for more than an hour.

Eggs Do Not Raise Cholesterol

For more than 50 years eggs have been called unhealthful because they are among the foods that contain the highest levels of cholesterol. However, in recent years eggs have been rehabilitated. This month, a team of researchers at Mahidol University in Bangkok showed that adding an egg a day to the diets of healthy people in Thailand raised the good HDL cholesterol that prevents heart attacks. It did not affect the bad LDL cholesterol or triglycerides (Journal of the Medical Association of Thailand, March 2008).

Adding as many as three eggs per day to your diet will not raise cholesterol. More than 80 percent of the cholesterol in your body is manufactured by your liver, and less than 20 percent comes from the food you eat. When you eat more cholesterol, your liver makes less. When you eat less cholesterol, your liver makes more. However, if you add eggs you must subtract another equal source of calories, because increasing caloric intake will raise cholesterol. So this is not an invitation to eat an unlimited amount of eggs. The study supports other research showing that eggs in moderation are not harmful, and that up to one egg a day may have specific health benefits. How to lower cholesterol
