      No matter what your reasons for eating more vegetarian food are, there is no denying the

obvious health benefits that result from the elimination (排除) of red meat from your diet. In

general, vegetarians have lower levels of blood fats,  cholesterol  (胆固醇) and  triglyceride 

 (甘油三酸脂) than meat eaters of a similar age and social status.

      High levels of blood fats are associated with an increased risk of heart disease. Lacto-ovo

vegetarians (乳类蛋类素食者), who eat eggs and dairy products, have higher cholesterol levels

than vegans  (绝对素食者). Even among lacto-ovo vegetarians, however, cholesterol levels

are generally lower than they are among meat eaters.

      Researchers have found that older men that eat meat six or more times a week are twice as

likely to die of heart disease as those that don't have meat. Among middle-aged men, meat eaters

were four times more likely to suffer a fatal heart attack, according to the study.

      As for women, who are partly protected by their hormones and generally develop heart disease

later in life than men, the risk of fatal heart disease has been found to be lower only among older

vegetarians. In a 1982 study of more than 10 000 vegetarians and meat eaters, British researchers

found that the more meat people consumed, the greater risk they had of suffering a heart attack.

      Though eliminating meat from the diet is likely to reduce your consumption of heart-damaging

fats and cholesterol, continuing to eat large amounts of high-fat dairy products and cholesterol-rich

eggs can reduce the benefit. The introduction of more vegetables, fruit and raw foods will definitely

enhance the benefits of giving up eating meat.
