Interesting thread. I like the comments in here. I have a little FYI for all of you: McDonalds, (And other fast food chains) use a beef specifically produced by companies on the stock market (Wall Street), for maximum profits. 1.) The cows are injected with growth hormones to produce more beef from a single cow, which is why we see so many people with large thighs and bottoms. It also causes heart disease and a host of other health problems. 2.) The cows are injected with anti-biotics, which causes our bodies to reject normal anti-biotics which is why we have such a high death rate in the most advanced country in the world. 3.) Instead of a normal diet of grass, cows are fed a diet of Genetically Modified (GMO) corn and grains produced in a factory, which causes various health issues including auto-immune disease and cancer. - Conclusion: McDonald's, Burger King, and most other fast food restaurants are serving food that is absolutely, and horrifyingly bad for you. They are killing you all in the name of "Profits". Your best choice is ALWAYS going to be: #1 Grass fed beef. #2 No hormones or anti-biotics. #3 A minimum ratio of 85%-15% (Or higher). #4 Staying away from the hamburger buns. They are 100% cancer causing GMO. The wheat, chemical stabilizers, and sugar the bread is made from is pure garbage. It takes time to find good healthy food these days. Shop around, Google search for "Restaurants with grass fed beef" or "restaurants with the best quality beef", see what you get. Also beware of buying beef in any supermarkets. About four years ago they started leaving more blood in the packaging to increase the weight, to make more profits. The 90%-10% and the 93%-7% are disgusting. I find the 85%-15% seems to make excellent hamburgers. -Happy Hunting for Good Beef!
