A high protein diet could lead to early death, claim researchers
|(Thierry de Lestrade) Salvatore Caruso, 108|
This is a fascinating study based on a large sample of adults tracked during nearly two decades. The data is compelling but additional research is needed to further understand the biological mechanisms at work. The researchers have been criticized for comparing smoking deaths with those (potentially) from eating high protein diets.
According to the Guardian newspaper: "Gunter Kuhnle, a food nutrition scientist at Reading University, said it was wrong "and potentially even dangerous" to compare the effects of smoking with the effect of meat and cheese as the study does."

High-protein diets: Bad for the middle-aged, good for the elderly
Photo: Like others in the small town of Molochio, with one of the highest prevalence of centenarians in the world, Salvatore maintained a low-protein, plant-based diet for the majority of his life, but switched to a higher-protein diet after moving in with his son's family once he became frail.

Note: Dr Longo (cited above) devised the periodic fasting program that I am experimenting with this year. I am intrigued - but not necessarily convinced - by the low/zero animal protein argument. But after two months on a Vegan diet, I feel good and my weight management issues have all but disappeared. I will be fasting again soon for five days.
