Introduction

Ever since 1977 and the United States Senate report on Dietary Goals, we’ve been asked to decrease our consumption of meat. During the 1980’s, the emphasis was on choosing lean meats rather than fatty cuts. During the 1990’s, the Dietary Guidelines published by the U.S. Department of Agriculture and the Department of Health and Human Services actually started telling us to limit our daily meat intake to 2-3 servings. But more recently, we’ve also been hearing many organizations, like the Harvard School of Public Health or Physicians for Social Responsibility, telling us we should move toward a vegetarian style of eating that includes meatless meals on a regular basis. So is it o.k. or not o.k. for us to eat meat on a daily basis?

Vegetarians Are Healthier Than Meat Eaters

Large-scale research studies, sometimes involving over 75,000 subjects, have repeatedly shown meat-eating populations to be less healthy than vegetarian ones. When large groups of people who eat no chicken, pork, or beef are compared to large groups of people who regularly eat these foods, the chicken, pork and beef eaters have consistently higher rates of arthritis, colon cancer, hypertension, diabetes, ischemic heart disease, obesity, and prostate cancer. While it’s impossible to draw conclusions from large, population studies to the diet of any one particular individual, the trend here is to move away from routine meat eating if you want to decrease your risk of chronic disease.

Meat Is Limited In Its Nutrient Composition

We include lean, organic beef as one of the WHF, and it is indeed a concentrated source of nutrients, including being an excellent source of vitamin B12. It also ranks as a very good source for numerous nutrients such as protein, niacin, vitamin B5, selenium, zinc, and phosphorus. If you compare lean beef to a vegetable like Swiss chard, however, the differences are striking. Swiss chard ranks as an excellent source of nine nutrients and a very good source of another 7 nutrients. The phytonutrient composition of beef is also very limited in comparison to a leafy vegetable like chard.

Another major consideration when comparing meat to plants is fiber. Animals have bones and muscles for physical support. Plants have fiber. By definition, the greater the percentage of animal products in our diet, the lower our intake of fiber. Since deficiency of fiber is related to many chronic diseases, including colon cancer, diabetes, and high cholesterol, many healthcare experts recommend a shift toward vegetarian eating as a way to lower our risk of these diseases.

Evaluating Your Personal Meat Intake

Before you can decide whether more meatless meals are for you, you need to ask yourself several questions about your current nutritional intake.
