I grow a lot of my own food as you known, I cook a lot of my own food, I shop very carefully,
I am very conscious about what I eat and I also take a good multivitamin/multimineral
and a few other supplements every day as insurance against gaps in my diet. As conscientious
as I am, for various reasons, if I am traveling, if I am running around town, I cannot eat
optimally every day. So I don't see dietary supplements as substitutes for the foods that
contain them because at best they are a partial representation of the spectrum of micronutrients
that are in foods. But I think they are very useful as insurance against gaps in the diet
and also some of these products in higher doses you can get from foods have specific
or therapeutic properties. Vitamin D would be an example which looks as if it is strongly
preventive of many types of cancer and other diseases and I think that it is best taken
as a supplement.
