dr. mercola has another, as does dr. fuhrman:
Confusion of ideas
Mercola’s views on diet and health fail Nutrition 101: too much science contradicts him. But not everything he says is incorrect. He correctly points out that most vegetarians may not have excellent health because of their overdependence on grains. The literature is abundant with evidence that demonstrates that the foods with the best correlation with longer life and resistance against later-life diseases are vegetables, beans, raw seeds, fruit, and raw nuts.
Notice that grains are not included on the list. Eliminating animal products and continuing the consumption of processed grain foods is not a recipe for health or longevity. The bottom line is most vegetarians are unhealthy: they eat too much processed food. Whole grains are not nutrient-rich foods. They can form a minor part of your diet, but when they are baked, fried, toasted, shot out of cannons or otherwise processed or adulterated, they become low-nutrient junk foods that are powerfully disease-promoting.
There is good science to back up Mercola’s contention that some people are not going to get all of their nutritional needs met on a vegan diet and will need to add supplements to make their diet complete or even eat small amounts of animal products.
There are two very critical areas where Mercola departs from universally accepted science. First, if you add the large amounts of animal products he recommends (including red meat and butter)—and especially the large amounts he recommends for his “protein-type”—you will have a diet that powerfully promotes heart disease and cancer. There is no genetic “type” that has immunity from such a high-saturated fat, disease-causing diet.
All Americans, not just some, develop atherosclerosis when they eat a diet so high in animal products. Over 90% of Americans eventually develop atherosclerosis and hypertension from the low intake of unprocessed vegetable, fruits, beans, nuts and seeds, and high intake of animals products. Diets like the ones Mercola recommends—especially if they include processed foods—also lead to premature death from heart attacks or stroke.
The second critical departure is that his metabolic typing questionnaire is not an accurate way to determine a person’s nutritional needs. When he advises his “protein type” to eat a diet in which most calories are supplied by animal products, he is appealing to that person’s food preferences and addictions. The more you crave something and the worse you feel when you stop consuming it, the more likely that you are addicted to it and that it is harming you, not helping. Encouraging people who are addicted to meat or other animal products to eat more of them will lead to even shorter life spans.
No need to be vegan
Keep in mind, I am not arguing that a person who eats no animal products (a vegan) will be healthier or will lead a longer life than one who eats small amounts of animal products (such as a small amount of fish or eggs). What I am pointing out s that as animal products increase in the diet (and natural plant foods are forced off the plate), the modern diseases that kill over 80 per cent of Americans (heart disease, stroke, cancer, diabetes) will occur in greater and greater likelihood in every genetic type.
My review of over 60,000 articles in the scientific literature supports the conclusion that if animal products are consumed they should constitute no more that 10% of total caloric intake. Remember, animal products are high in calories and very low in nutrients-per-calorie compared with vegetables. The higher animal product consumption compared to a vegetable-based diet, the lower the nutrient intake. The typical American gets 40% of total calories from animal products (those on the Zone and South Beach diets get 60%, and Adkins adherents get 80%). Mercola’s high protein type diet is in the 60-80% range. Diets like these are extremely high in dangerous fats and extremely low in nutrients and phytonutrients.
