Coffee

There is some evidence that coffee may induce a Th1 response.

Arabinogalactan, a coffee bean polysaccharide, increased the production of macrophages as well as of Th1 cytokines IL-12p40 and IFN-gamma. It also ameliorated allergic response in a mouse model of dermatitis.

Coffee reduces the risk of liver, kidney, premenopausal breast cancer and colorectal cancer.
