Is what we're eating making us unhealthy?

What to eat, what not to eat..what to feed to our children. Where to buy, from who..in season or not? Organic or regular..local or from across the seas?  Being vegetarian, vegan, or nothing?
OGM, MSG, HFCS.. Healthy/Unhealthy..
We have so many choices nowadays of what to put into our bodies. How and when and where to buy it. What brands, types of food..
It is enough to make you crazy. Then to top it off, we have the Internet..which can give you hundreds of opposing sides to any argument, depending on their ulterior motives, advertising, misled information/people trying to share their knowledge or information/or personal bias.
Here's one example..
Organic..it's the best thing in the world.for our bodies, the environment, for the smaller farms that grow these foods..it's a win-win situation for everyone.
Then you read some random articles like these..and it makes you think twice about things.

An article here at livingmaxwell

Why tofu wrecks your brain

And this article on Born free USA

Which isn't necessarily a bad thing. Personally, I feel  that we don't think enough of where our food sources come from.
But again..it just makes you crazy, always doubting, second-guessing, justifying things(one way or the other).
What is one to do? Anyone have some ideas? What do you think?
We'd love to hear your thoughts/opinions!
