Foods that were once thought to be very good for your health, are still good for your health. BUT, many of them also have added problems and dangers associated with them that they never had before.
There are some more commonly known problems such as the use of pesticides, toxins and other dangerous chemicals that now exist in non-organic foods. These can lead to various health problems and conditions. Just do a search for "side effects of pesticides" and see what you come up with.
But aside from these issues, there is a very big problem even worse than pesticides; Genetically Modified Foods. The US does NOT require labeling of GMO foods. Fruits and vegetables are some of the most commonly modified foods. They are created in labs and then patented as something the said company owns. There are no laws about the safety of these foods being put into distribution. They are only required to have a patent. Some foods that are VERY likely genetically modified are soy, corn and it's products (canola oil, high fructose corn syrup, etc.) and wheat.
So just by eating the way our pre-agricultural ancestors ate, we can avoid some of our present day dangers all together. We already know that grainfed animals are the "protein equivilant of cardboard." We also now know that there are some potentially dangerous effects of the other foods we are eating as well. So if we are trying to live as healthy and disease-free as possible, let's think more carefully about what we put in our bodies. Buying organic, grassfed, local products is good for the local community, good for your health, and good for future generations.
"A plant, fruit, or animal grown without the administration of artificial pesticides, herbicides, or insecticides, chemical fertilizers, antibiotics or growth hormones (in the case of animal products), most closely replicates wild or untampered-with growing conditions" - Mark Sisson
