Going through life, thinking that a your diet that deprives you of cake, sugar, wheat would be a tough think indeed. Going through life knowing these are low grade poisons, and should not be in the food supply, along with trans-fats, lubricants, alcohol, and the like makes some editable products akin to Russian roulette. No temptation to consume these. End of story. I do not want to eat traces paint thinner either (seed oils), so fast food is out.
No deprivation thinking either. It is all just chemicals. Just avoid the chemicals as best we can.
