Dietary Intervention and BRCA Penetrance

"The main aim of the trial is to reduce serum levels of IGF-I and IRm with a a low- calorie and low-protein diet. In humans, calorie restriction alone does not seem to significantly lower IGF-I; protein restriction is also required. In detail, recommendations for participants included in the intervention arm include:~* reducing protein intake, mainly milk and animal protein (except fish), down to 10-12% of total calorie intake.~* reducing high glycemic index food and high insulinemic foods.~* reducing sources of saturated fat (red and processed meat, milk and dairy products).~* eating mostly food of plant origin, with a wide variety of seasonal products."
