You can explore the research related to each disease in the tabs below, but heres the evidence-based takeaway: eating healthy protein sources like beans, nuts, fish, or poultry in place of red meat and processed meat can lower the risk of several diseases and premature death. ScienceDaily. Nature 275, 416420 (1978) doi:10.1038/275416a0, Levinthal, C. Are there pathways for protein folding?
