Actually, regarding the contamination of foods, look no further than Aspartame, Ritalin, fluoride, and others found in most of our popular food and drink. During the Nazi concentration camps, fluoride was used in the water supply to make prisoners more docile and easy to control. That?s why they put fluoride in our water supplies and toothpaste.
P.s. Soft Drinks are heavily contaminated with Aspartame, which in the old days was known as Hemloch, apparently.
