Turmeric
Turmeric is a yellow spice that many people use in cooking (it is what gives curry its yellow color). But it is also used in some alternative medicines. Consuming turmeric may improve a person’s immune response due to the qualities of curcumin, a compound in turmeric (This same compound is what lends turmeric its signature vibrant orange-yellow color). In traditional Chinese medicine, turmeric is used as an anti-inflammatory.
According to a study published in the Journal of Clinical Immunology, curcumin activates the production of T-cells, which are the main cells fighting for your health in your immune system. It’s also known to reduce LDL cholesterol and to enhance cognitive abilities.
