The authors "investigated the associations between total, animal, and vegetable protein and incident type 2 diabetes (T2D) in 72,992 women from the Nurses' Health Study (1984-2008), 92,088 women from Nurses' Health Study II (1991-2009) and 40,722 men from the Health Professionals Follow-up Study (1986-2008)"

Key Findings

Key Findings: Authors found that substitution of one serving of animal protein with a serving of plant protein significantly lowered diabetes risk. They also noted, "substituting 5% of energy intake from vegetable protein for animal protein was associated with a 23% reduced risk of type 2 diabetes. In conclusion, higher intake of animal protein was associated with an increased risk of T2D, while higher intake of vegetable protein was associated with a modestly reduced risk." Plant proteins were from peanuts, peanut butter, legumes, and wheat products.
