It has to do that you are either th1 or th2 dominated or even t 17 then it means you are both , then there are certain foods what will make you worse if you are one or another , and there are foods what will make you feel better. I am both and both groups make me severe depressed.
Th1 Stimulating Supplements:
Generally, immune-boosting herbs such as echinacea, astragulus, licorice root, ashwaganda, panax ginseng, chlorella, grape seed extract, and common immune-boosting medicinal mushroom extracts, like maitake, reishi, and shitake, will stimulate Th1.
Th2 Stimulating Supplements:
Antioxidants like resveratrol, pycnogenol (found most notably in apples), curcumin from turmeric, genistein, quercetin, and green tea will stimulate Th2.
