Many places have co-ops which go out and find sustainable healthier raised meats and often other food
products like vegetables, seafood, butter, lard, etc. There's no guarantee, and people throw around
monikers like natural and organic to sell food products. But many or most co-ops are making a serious
effort to upgrade what you eat, at a not huge extra cost. Most of these co-ops focus on locally produced
food and smaller family farms which can produce in a more healthful way and need to, to maintain their
market niche. This isn't a cure-all, but it is one approach to trying to eat food with actual nutritional
content and without serious contamination issues. Most chain restaurants buy food without regard to
its sources. Think agribusiness farms, many overseas, coated in pesticides, and meat entirely from suspect
industrial confinement and feedlot sources. This is not really food; it is a food substitute aimed at sales.
Little food value is present. Also true of most corn and soy based processed food products, many of them
made with genetically modified crops. Ingredients are listed with the highest percent first, so anything with
fructose or other synthetic sugars in the first two or three ingredients is probably without much nutritional
value. Eat variety. No tuna sandwich four lunches a week, maybe twice a month. Seasonal vegetables are
fine if you buy them at a farm stand from the farmer; you can overeat those, if you feel secure they are
local and not pesticide laden. In my opinion.
