The higher the ratio of protein intake from vegetables to the protein intake from animal products, the fewer hip fractures occur.8 The magnitude of difference was substantial: While a vegetable-to-animal-protein intake ratio of 1:1 or less was associated with as many as 200 hip fractures per 100,000 population, a vegetable-to-animal-protein intake ratio of between 2:1 and 5:1 was associated with less than 10 hip fractures per 100,000 population—a reduction of more than 95 percent. (At the highest intakes of vegetable protein, the incidence of hip fracture practically vanished.)
