Many food "beliefs" have, upon further study, shown to be inaccurate. As for GMO foods, well as you said, there are many, many more people than in decades past....more mouths to feed with the same amount of land available for growing. Genetic manipulation in plants is far from new. People are easily frightened by what they do not understand. Organic is not necessarily better. We have to remember, that food is just that. Eating ANYTHING in excess isn't good. Learning to modify eating habits will do more for those who might be ingesting in excess than trying to adhere to so many unproven or disproven food facts. Low fat my ***...
It's just food....eat what you want, in amounts that keep you happy and healthy.
As has been written, the amount makes the poison, not necessarily the ingredient.
The media "grabs" little tidbits, incomplete study info and takes it for the touchdown...when in reality, there may be no actual SCIENCE to support those bits of "information."
