First of all, I agree with the idea of eating natural food as opposed to processed, artificial foods. This, however, is not as easy as it seems, as it may difficult and expensive to obtain organic foods if you don't know where to look, but the benefits definitely outweigh the monetary cost. This article from MSNBC warning of the high sodium content in processed foods is just one of the hundreds of thousands of articles in opposition to these foods.
The next point I agree with is his argument regarding the flood of artificial food is caused by big companies trying to make a profit. They pump all of those chemicals into the food for flavoring, as they know good flavor will sell the product, and nutrients, which also cause it to sell thanks to nutritionism. This seems reminiscent of the big tobacco companies selling a product while trying to downplay its negative effects.
