Yes, more people need to know about this, if they realized how much was in the food they wouldn't be eating it.
If you can't afford everything to be organic, then think carefully about how much weedkiller a specific item will have absorbed, like for example strawberries and raspberries, they absorb it easily, whereas a banana is fine as any weedkiller will be in the skin. Always wash fruit/veg that you buy.
Avoid corn flakes and other cereals, unless organic. There is one good make of cereal to look out for, Nature's Path, their soil has never grown crops using weedkiller, so everything is top notch as it should be.

On another note, avoid tap water (unless you have good filter or distiller), it's got chlorine, while it does have to be there it's not good for you, only use it for washing. Look specifically for 'mineral water', as that means it is untouched, nothing added. Some mineral waters are better than others, look into if there is farming on the land above the water, and see if you can find out how long it gets filtered for (through rocks). I'd give a strong recommendation for Volvic, and as an added bonus it's known for removing aluminum from the body, thereby lowering the risk of Alzheimer's.
