No. We as humans are designed to eat meat, vegetables, fruit, grains, and a small amount of oils and sugars (your basic food pyramid). As with anything, too much meat CAN be bad for you. It is better to eat red meats in moderation as they can cause high cholesteral, but so can a lot of things. Lean meats like turkey, chicken and fish are very healthy for you. Meat has proteins that we need to survive and function properly. You should also make sure your meat doesn't have a fat content of higher than 80/20. 90/10 or even 95/5 is what we usually eat, and it is healthiest for you. As long as you eat meat in the proper proportions (a serving should be no bigger than the size of your fist) and balance it out with fruits and veggies, you will have a normal healthy diet. Besides, meat is too delicious to not eat! As for the person who said that humans are the only ones to get sick from the wrong food, they must not spend much time around animals. Animals are constantly eating things that are bad for them and getting sick. Just because they don't cart themselves off to the doctor doesn't mean it doesn't happen.
