French and Italian drink mostly red. Red has the Zn. They drink white with seafood but seafood is loaded with Zn. Either way they get it.
Here our red meats should have lots of Zn but unfortunately don’t. Our soils are depleted of Zn and other nutrients.
I predict there will be years of study how we can get nutrients in our diets that provide protection.
But for now, Dr. Z’s Zinc supplement is plenty and it’s cheap.
I’m taking no chances.
