According to Kathy Freston, the New York Times bestselling author of "The Lean, Veganist, and Quantum Wellness", vegetarians and vegans have significantly longer life expectancy. Based on doubtful studies and media claims, vegetarians are trying to push us eliminate meat from our diet. But there are other findings, which conclude that a vegetarian diet conferred no more benefit than a diet that included plenty of unrefined plant foods together with animal protein.
According to a recent report on the largest study on vegetarians and vegans, they live an average 8 years longer than the general population. The study was based on our leading causes of death, such as heart disease, cholesterol level, cancer, stroke, COPD, Alzheimer disease, kidney failure, and depression. According to this study, all mentioned causes of death may be prevented or even treated using plant-based diet.
Statistic from CDS (Centers for Disease control and Prevention) shows that heart disease is a leading cause of death in the United States. A long-term study on older women's health was recently published, showing that "consuming the amount of cholesterol found in just a single egg a day may cut woman's life short as much as smoking five cigarettes daily for fifteen years, whereas eating a daily cup of oatmeal's worth of fiber appears to extend a woman's life as much as four hours of jogging a week." (Freston, 2012). In this study dietary cholesterol intake (only found in animal foods) was associated with living a lot shorter life and fiber intake (only found in plant foods) was associated with living a much longer life. According to Dr. Dean Ornish heart disease could not be only stopped but even reversed with a vegan diet, arteries opened up without drugs or surgery.
It is a known fact that high cholesterol levels cause a build-up of plaque in our arteries which leads to heart disease, but it is hard to believe that eating one egg a day can be as harmful as smoking five cigarettes daily for fifteen years. One chicken egg has about 186 mg of cholesterol and all of it is in the yolk. However recommended daily limit on cholesterol in your diet varies from person to person. If you are healthy, it is recommended that you limit your cholesterol intake to 300 milligrams a day, but if you have cardiovascular disease, diabetes, or high blood cholesterol level, you should limit your dietary cholesterol to less than 200 mg per day. According to Dr. Thomas Bechrenbeck, eating eggs can increase you cholesterol, but eating up to four eggs on a weekly basis hasn't been found to increase your risk of heart disease. So, if you decide to eat an egg it is important to limit other sources of cholesterol on that day. When it comes to meat, it is a similar story, you have to watch for how much you can eat daily, in order not to increase your cholesterol. Any kind of 8-oz. steak has about 200 mg of cholesterol, which is a recommended daily limit by The National Heart, Lung and Blood Institute. So if your consider eating meat, you should not eat more when 8-oz of lean meat on any given day and avoid any other foods, which can contain cholesterol. According to American Heart Association on occasional 8-oz. steak won't significantly impact your heart health, but frequent or large servings do make a difference.
Second biggest cause of death is cancer. According to the study on the subject of diet and cancer, "the incidence of all cancers combined is lower among vegetarians." But there is a different study from 2006, which found no differences in "cancer rates between vegetarians and non-vegetarians." (Who's Healthier - Vegeterians or Meat Eaters?, 2012). However, same study showed that vegetarians have lower body mass index, lower cholesterol level, and they also had 20% fewer deaths from ischemic heart disease. The European Prospective Investigation into Cancer and Nutrition-Oxford study showed that in the...
