A mother is bi polar, the daughter is likely to have it too because of DNA. A kid is fat, is likely to be fat forever because of DNA. We go to DNA because we have no solutions for these problems in the mass media. We know that mental diseases are not hereditary, are not something you must deal with, but actually are directly caused by what you eat. I think SAD sends negatively impacts you one way or another. There are tons of websites out there of awed parents who discovered that following a cooked paleo diet does for their autistic children. Reading those really makes you feel like you've been fucked with by the corporate elite by being brainwashed about what's food, and what's not.
Of course we are like our parents, but the emphasis on DNA is crap. As long as I know it I'm happy, I don't care about helping anyone else, I guess I'm just venting on here.
