I can only think that foods and activities that help boost nutrition and reduce stress would contribute something - - though may not be preventative of anything. We can only do the best we can do. Increase fresh (hopefully not pesticide treated) raw or steamed veges, ingest anything and everything rich in anti-oxidants, lots of good water, plenty of rest, , little or no white stuff (sugar, wheat, salt)!

Now if I was only better at these things myself!!
