Dietary intake of branched-chain amino acids (BCAAs), serum BCAAs, and cardiometabolic risk markers among community-dwelling adults.

Dietary BCAAs in poultry, whole grains and nuts, soy, and vegetables and fruits may be favorably, while BCAAs in red and processed meat, fish, and refined grains were unfavorably associated with cardiometabolic health. Serum BCAAs showed a detrimental association with cardiometabolic risk markers.
