High-protein cancer link
A high-protein diet can increase levels of hormones linked to cancer according to new research published in the American Journal of Clinical Nutrition. This study showed that people who ate what was called a ‘low-protein’ diet (0.73 grams of protein per kg of body weight – which is just under the recommended daily amount of 0.75 grams), had significantly lower serum levels of growth factors and hormones linked to certain cancers than people consuming 1.23 grams – the amount of protein a standard Western diet, high in sugars, processed and refined grains and animal products, contains.
