Summary

This pilot study tested whether a diet designed to lower insulin levels could reduce breast cancer risk in 34 high-risk women. The diet is rich in fruits, vegetables, whole grains, and plant protein, and low in animal protein and fat. The main goal was to see if women could stick to the diet, not yet to measure cancer outcomes.
