healthy 'eart'?

From reading the first reason, the only thing that is apparent is that the author of this Article missed the evolution boat fantastically.

1: By that logic, animals that only eat meat should be building supercomputers. The correlation of meat + intelligence may be from things like, say, cultures evolving from hunters bartering with villlagers for food. 2: Again, uncontrolled correlation doesn't say anything. By your logic, the regions where people tend to die after long sicknesses are hospitals, therefore we should not go to hospitals? 3:Protein can be sourced from all-plant sources - it's inconvenient, but it's also convenient to steal from a store rather than pay. 4: This is true, but it's also true that first-world countries (read - basically everyone able to afford internet) pretty much don't have problems with zinc, iron, or magnesium deficiencies. 5: If only, say, cows have vitamin B12, where do they get it? There are bacterial methods of producing B12, and "animal sources" doesn't mean you have to eat the cow to get the B12. 6: Your body makes its own carnatine, and plenty of plants make it, too. A sip of milk will basically give you all you need. 7: You have to test the whole package to make that claim. Beef and lamb may have other things that greatly increase cancer risk that overpower linoleic/palmioteic acids (check all the primary literature involving beef and increased incidence of colon and prostate cancer) I write this all as I eat my chicken pesto pizza. Go on, eat your meat - but be honest and say you eat meat because you like the taste of it. 1: By that logic, animals that only eat meat should be building supercomputers. The correlation of meat + intelligence may be from things like, say, cultures evolving from hunters bartering with villlagers with excess meat from a hunt. 2: Again, uncontrolled correlation doesn't say anything. By your logic, the regions where people tend to die after long sicknesses are hospitals, therefore we should not go to hospitals? 3: Protein can be sourced from all-plant sources - it's inconvenient, but it's also convenient to steal from a store rather than pay. And if analogy doesn't suit you, check the reduced mortality study Clifton showing heart attacks being less serious if you switch out animal protein with vegetable protein, for instance. 4: This is true, but it's also true that first-world countries (read - basically everyone able to afford internet) pretty much don't have problems with zinc, iron, or magnesium deficiencies. Meat is nutrient-rich - but when was the last time you (or anyone around you) was actually worried about malnutrition? 5: If only, say, cows have vitamin B12, where do they get it? There are bacterial methods of producing B12, and "animal sources" doesn't mean you have to eat the cow to get the B12. 6: Your body makes its own carnatine, and plenty of plants make it, too. A sip of milk will basically give you all you need for the day. 7: You have to test the whole package to make that claim. Beef and lamb may have other things that greatly increase cancer risk that overpower linoleic/palmioteic acids (check all the primary literature involving beef and increased incidence of colon and prostate cancer) I write this all as I eat my chicken pesto pizza.

You need to cite your sources.

Our brains grew because we ate meat? I think the real reason our brains evolved is because if we didn't learn to use weapons and build shelters the human race would have been wiped out pretty quick. Look at the T-Rex it ate nothing but meat and it had a tiny brain compared to it's body. In fact if we carry your theory to it's logical conclusion then all meat eating animals would be super intelligent. By the way it's not brain size that denotes intelligence it's brain type. Not to mention the fact that our ancient ancestors would have been eating meat from wild animals, not from factory farmed animals pumped full of growth hormones and other dangerous chemicals.

Simple rule. Can you kill a cow with ONLY your hands? NO! Beef was never meant to enter the human body. Same goes for dairy. Chicken, turkey, rabbit can be captured and killed with only your hands. It should be eaten. Vegetables, fruits, pasta(wheat), rice, etc... are things that are easily gathered and easily digestible. If you have to use toilet paper to wipe yourself. Your eating something that was never meant to enter your body.

This is one of the reasons india never produces world class atheletes. They need to start eating cow meat to get stronger and smarter.
