       | There also isn't a fundamental difference between a synthetic and

             |

           | chemicals: that is, compounds, preservatives, dyes, and

           | food item and were added for their shelf life, taste,
           | aesthetic, or addictive properties.
           | 
           | Next time you visit your grocery store, go read the
           | ingredients list of a few different boxed and frozen items.
           | It's not uncommon to see three- or four- dozen ingredients on
           | items that should have less than 10.
           | 
           | While all of these compounds may have FDA approval and
           | studies verifying their safety for ingestion, please keep
           | several things in mind:
           | 
           | 1. Studies use large, population-based sample sizes and their
           | effects are based on their statistical significance on these
           | populations. In other words, "side effects" are a population-
           | level phenomenon, not an individual phenomenon. It is
           | plausible that individual side effects are hidden as
           | statistical noise. This is a problem with pharmacological
           | studies as well and there is no easy solution to it AFAIK.
           | 
           | 2. We have a massive obesity crisis in this country (and
           | increasingly globally). Sedentary lifestyles and increased
           | caloric intake is no doubt part of this, but it is blindingly
           | obvious (to me, at least) that the meat of the problem is
           | environmental, primarily diets, and these compounds are
           | wreaking havoc on the endocrine systems of the population
           | causing a massive uptick in obesity and diabetes.

             | 
             | 4. Interactions are even harder to establish, since the

             | explode. This is the primary reason for a precautionary

         | The sheer percentage of artificial food dyes that have been

         | American farms and the entire supply chain is pretty hardwired
         | to corn and soy, for the same reasons punjab/haryana farms are
         | hardwired to rice (even tho it's arid land, rice isn't even
         | native, thus uses up groundwater too fast).
         | 
         | Government-set/subsidized price floors, insurance, storage
         | programs specifically for 4 program crops, of which one was
         | corn, and to which soy was a later addition. India has the same
         | thing for rice etc.
         | 
         | Soy/corn rotation also caused extreme lock-in, since soy leaves
         | a lot of nitrogen in the soil after harvest, and corn needs a
         | lot of nitrogen.
         | 
         | There are many other factors, but essentially, the entire farm
         | supply chain is locked in to corn/soy in most American farmland
         | similar to how most punjab/haryana supply chain is stuck in
         | rice/wheat alternation and resulting farmland/aquifer overuse.
         | 
         | In america too corn soy are not native. And the excess nitrogen
         | goes down the rivers and causes hypoxia in the gulf of
         | (mexico|america). Very symmetric problem.
         | 
         | It's extremely expensive to get them to grow anything
         | different. For starters, removing the price floors and such is
         | electoral suicide. Most of the farmers (that remain) depend on
         | these things heavily. You can complete the rest...
         | 
         | More random stats: 40% of us corn goes to animal feed, 40% goes
         | to ethanol (for blending with petrol among other things), and
         | the rest is other stuff.
         | 
         | Even more: 70% of soy goes to animal feed, primarily broiler
         | chicken, 15% goes to oil. Margarine, processed crap, lots of
         | fried goods, all use this. I think you can even make plastic
         | with it. I forgot what the other 15% was... And the people
         | actually eating tofu, soy milk, etc are a tiny percentage and
