Does it ever say which foods to eat???
Nutrition factor 1 scores (vitamin C, quercetin, β-carotene and β-cryptoxanthin)
Nutrition factor 2 scores (vitamin E, lysine, DHA omega−3 and LA omega−6)
Nutrition factor 3 scores (epigallocatechin 3-gallate)
Various foods have each of these, except the last one, which is EGCG that primarily comes from green tea, followed by white tea, and basically nothing else.
DHA Omega-3 comes from salmon and other ocean-based fatty fish. Omega-6 comes from some plant fat and animal fat.
I will leave the rest as an exercise for others to add to, but there are plenty of websites that tell you foods high in each.
