The protein in eggs can significantly increase the levels of tryptophan in the blood. Tryptophan is the building block of serotonin; the brain chemical that both stabilizes mood and boosts pain threshold. Tryptophan also raises endorphin levels in the brain and body!
Cheese, salmon, and turkey are also excellent sources of tryptophan. Vegan and vegetarian options include nuts and seeds, pineapples, and tofu.
Lamb is an excellent source of zinc, an essential mineral with many functional roles in the human body. According to the Arthritis Association, “Studies show significantly lower zinc levels in people with rheumatoid arthritis compared to those without it.” Individuals whose tests revealed “the lowest levels (of zinc)” tended to have it worse off.
Other meat sources of zinc include seafood, red meat, and poultry. Fortified cereals; bean, nuts, seeds (especially pumpkin!), and whole grains are good non-meat sources of the mineral.
