Thankfully in Europe it's pretty much isolated to livestock feed at the moment, if it ever becomes mainstream you can also be sure it will be clearly labeled (like everything else is these days here). This also goes for high fructose syrup use, which is another ongoing health and safety issue people need to look into more (imo).
Really anything Corn based (including the hfs) is considered bad. As Corn is one of the biggest GMO'd crops out there. The problem is, everything we eat is refined to the point where it is no longer nutritionally good. We break sugar down until all it is is sweet, without any of the nutrients that are originally found. Vegetables used in oils are no longer healthy and don't provide the benefits of eating olives, or others. Meat is so injected, and.. well.. fake in most cases that there is no nutrition value like it used to have.
I buy 99% of my meat from a local market which gets all their meat locally and grain fed (also get veggies there). We also get free range chickens from a guy who lives near a farmer, as well as free range eggs. I also avoid gluten when possible, and try to only eat organic sweets. I buy chocolate bars, but they are 100% cane sugar, organic cocoa, etc. They cost a pretty penny, but after eating like I do, a standard chocolate bar would be way way too sweet, and wouldn't taste near as good. Same with pop, I buy pop but it's made out of organic cane juice, natural flavors (ie real ginger). None of the High Fructose Corn Syrup ####.
