It seems that many people in the U.S. maintain a special kind of hatred for things like Coca-Cola and McDonald’s. I have been consuming both for my entire life w/o problems. I might say “everything in moderation” but I drink more than two liters of Coke every day and have done for around fifty years. Some would say that was immoderate. But McD can be consumed in moderation and in health. Take a look at this link. Most of us are familiar with the move “Super Size” where a guy ate nothing but McD all month and got fat and unhealthy. It was mendacious. The man simply consumed lots of fat and calories. Do that with any diet and you get fat.
The link here shows a science teacher in Iowa, who ate nothing but McD and LOST weight, while lowering his cholesterol. He ate Big Macs, but also other things available at McD and did so in moderation with a healthy lifestyle.
I enjoy a Big Mac at least once a week. I also regularly eat pizza, tacos & processed flower. I am happy if my food has GMOs. I drink around 30 liters of Coke Zero each week. I almost never drink water unless mixed with extracts of things like cola nuts, barely, hops, or corn. And I love salt. I do also like vegetables; I eat them with my Rammen. My health is exceptionally good because it is possible to be very healthy w/o going organic.
You just don’t need to worry that much. Pretty much everything you eat, drink, breathe or touch CAN cause cancer if you consume too much. But most of us don’t. So eat that Big Mac and take large fries if you want. But walk more and be sensible. And, yes, Coke Zero and McDonald’s can be part of a sensible diet.
If you eat nothing but rice cakes and organic food, while avoiding Coke, candy, fast foods, booze and donuts, you will not live longer, although the boredom might make it seem that way.
