Ginger and garlic would be a good start
Good recommendations here, and definitely things you can pretty easily incorporate into your diet.
As for supplements, there are several of these things that I like to add to my diet as supplements (along with where you can get them from whole foods):
-Kyolic Aged Garlic Extract (garlic, obviously)
-Lycopene (tomatos)
-Bromelain (pineapples)
-Curcumin (tumeric)
-Spirulina (itself, I just prefer tabs to the taste of the powder)
-Boswellia (probably best to just get a supplement for this one)
I don't really enjoy eating a lot of vegetables, and I really don't like salads, so I make a lot of shakes and soups in the Vitamix blender.
