High-Protein Diets Dehydrate Even the Very Fit

Mon Apr 22, 2002

By E. J. Mundell

NEW ORLEANS (Reuters Health) - High-protein diets place such a strain on the kidneys that even very fit athletes can become dehydrated, according to researchers.

"Personally, I would not recommend a protein intake of over 2 grams of protein per kilogram of weight per day, as it may have negative long-term effects," said researcher William Forrest Martin, a graduate student at the University of Connecticut in Storrs. He presented the findings here Monday at the Experimental Biology 2002 conference.

Short-sightedness may be tied to refined diet

by Douglas Fox

The food children eat might play as big a role as books and computer screens when it comes to causing short-sightedness.

Diets high in refined starches such as breads and cereals increase insulin levels. This affects the development of the eyeball, making it abnormally long and causing short-sightedness, suggests a team led by Loren Cordain, an evolutionary biologist at Colorado State University in Fort Collins, and Jennie Brand Miller, a nutrition scientist at the University of Sydney.

Blood Flow to Heart Hampered After High-Fat Meal

Mon Apr 1, 2002

NEW YORK (Reuters Health) - While a lifetime of fatty meals can lead to a heart attack, a study released Monday suggests that chowing down on just one high-fat meal can interfere with blood flow to the heart in healthy young men.

In the study, 15 healthy men in their 20s or early 30s consumed a shake containing a whopping 1,200 calories and 100 grams of fat--roughly the equivalent of eating a fast-food meal plus dessert. All of the men underwent a heart test and had blood samples taken before and after consuming the liquid meal.
