Well, one should be concerned with GMO's in their food. Genetically Modified food is absolutely disgusting. And it is very dangerous games they are playing because some of these genetics are reproducing destroying real natural food. One unfortunately should avoid Big agriculture foods and most in grocery store chains are stocking their shelves with them. One instance is Heinz Ketchup. They use GM Tomatoes and God only knows what else. They are strong arming Local Ketchup producers off the shelves. Russia used to have like 15 varieties of ketchup and 5 different companies, now one goes to a grocer to find Heinz everywhere. TV commercials, Heinz... And you can see they pay money to make you buy the product and you don't get what you bargain for, but a Science lab project goes in your stomach. Not very healthy. One should always be aware of GM foods. Greenpeace has a blacklist of products that contain them.

Processed foods are dangerous. So many have soy in them, back in past Soy was only used in paint and paint thinners. Now it is everywhere. Health food shops buy in bulk so natural products are cheaper than in supermarkets. I am 74 years old. Mg foods have protected my heart from attacks even though I have had Irregular Heart Beat Episodes since 1995. Selenium foods protects brain from strokes. A mouthful of dry rolled oats is natural food remedy for Gastric Reflux. Doctors now are peddlers of drugs getting Freebies from Drug companies. Doctors of my generation can be proud that they kept Hippocratic oath.
