High-Protein Diets May Raise Cancer Risk
It’s become easier.Photo by Salah Malkawi/Getty Images Trying to find gluten-free foods? But in a new survey, nutrition experts predict that gluten-free diets will reign as the top diet trend in 2014, reported KSAT on March 14 . Conducted by Today’s Dietitian magazine, the survey asked more than 500 dietitians to cast their predictions for various diet trends. And although gluten-free diets used to be limited to individuals with celiac disease, now many dieters are choosing to ban wheat and other grains containing gluten for reasons ranging from weight loss to brain health. What’s the connection between going gluten-free and weight loss?

Eat more, die young: Why eating a diet very low in nutrients can extend lifespan
Results showed that both high and moderate protein groups were at a higher risk for diabetes mortality compared to the low protein group. Researchers noted however that this needed further study to solidify the link. Results also showed that among those between the ages of 50 and 65, high protein levels were linked to significantly increased risks of all-cause and cancer mortality. In this age group, those in the high protein group were four times more likely to die of cancer than their low protein group counterparts. When researchers analyzed the animal-plant protein variable, they found that when they removed animal protein from the statistical sample, the link between high protein consumption and mortality disappeared.

Scientists have known for decades that severely restricted food intake reduces the incidence of diseases of old age, such as cancer, and increases lifespan. “This effect has been demonstrated in laboratories around the world, in species ranging from yeast to flies to mice. There is also some evidence that http://www.reuters.com/article/2014/01/13/idUSnHUGdsQR+73+ONE20140113 it occurs in primates,” says lead author, Dr Margo Adler, an evolutionary biologist at UNSW Australia. The most widely accepted theory is that this effect evolved to improve survival during times of famine.
