They can do as they wish, but they should stop conning others into their drivel. And drivel it is, as the evidence shows.
FACT: Vegetarians die younger, according to census data
FACT: Vegetarian kids are sicklier, according to the Archives of Pediactric Adolescent Medicine that tracks such things
FACT: Vegtarian diets do NOT make you more "regular". Even teen vegetarians are 8 times more likely to need and use laxatives
FACT: Researchers at the University of Massachusetts Medical School have linked meatless, low protein diets to slumping sex function and muscle loss and bone damage.
FACT: Nature dictates what any creature is supposed to eat, and each animal (Man is an animal) has the teeth necessary for the diet best suited to them and their survival. Herbivores (i.e. cows, sheep, rabbits etc.) have incisors and molars, suited to eating plants. Carnivores (i.e. wolves, cats etc.) have canine teeth for ripping flesh. Man has the teeth of an omnivore - an animal that eats both plant and flesh. We have incisors and molars, but also bicuspids and canine (eye) teeth. Ergo, nature says we need meat in order to maintain our health.
And here is more news - the deadliest factor in heart disease is not cholesterol, as many believe. Cholesterol is harmless until it "catches" on a rough spot in your arteries, and then builds up from that. And the thing that causes those "rough spots" is a little thing called homocysteine, which corrodes arteries like a rusty pipe. And can you guess what the best way to reduce homocysteine is? You guessed it - eating red meat.
For those who believe in the Old Testament, it is written in Genesis that God tells us what our sources of food shall be. It includes meat.
And for those of you who may still doubt the veracity of this, perhaps you should spend time sitting outside a vegetarian store and watch the customers. You will find that the majority of them are more sickly looking than the average person who walks into a butcher shop. I'm not kidding. Check it out for yourself.
Vegetarianism has other problems as well, including some serious problems for the ecology and the economy. If Man were to become vegetarian, there would be no raising of livestock (reducing jobs and eliminating many businesses). No livestock means no fertilizer for all the plants we would have to grow. This would result in a reduction of food sources, driving prices up and increasing hunger throughout the world. If you doubt that, the simple act of mandating 10% ethanol in our gas resulted in food shortages and higher prices worldwide.
Anyone who wants to be a vegetarian has every right to eat what they want. But don't BS the rest of us with your bogus excuses and disproved myths of better health. It ain't so.
