Dr. Mercola’s Advice vs. Conventional Nutrition Guidelines

Well-known proponent of alternative medicine and natural health approaches, Dr. Joseph Mercola regularly offers opinions on nutrition that contradict accepted wisdom. Especially with relation to the use of fats, carbohydrates, and processed foods, his viewpoint differs greatly from accepted dietary advice. Although health organizations like the USDA and the World Health Organization (WHO) provide certain dietary recommendations, Dr. Mercola contends that many of these conventional suggestions might not support best health. His method stems from his conviction that improved long-term health results from a more individualized and comprehensive approach to diet.

The Part Carbohydrates Play in Dr. Mercola’s Diet

Dr. Mercola disagrees with traditional wisdom that says daily calorie consumption should mostly come from carbohydrates. Advocating a low-carb, high-fat diet, he feels it supports improved metabolic health and weight control. Dr. Mercola advises against refined carbohydrates and sugars and supports the eating of organic, low-glycemic fruits and non-starchy vegetables. Dr. Mercola claims that overconsumption of processed foods heavy in carbohydrates can cause insulin resistance, obesity, and other chronic diseases. This kind of view runs opposed to the advice of groups like the USDA, who still stress whole grains as the foundation of a healthy diet.

Give whole, natural foods top priority.

Dr. Mercola’s advise also deviates from accepted wisdom in conventional nutrition in his focus on whole, organic foods. Although conventional wisdom says many processed foods fit a balanced diet, Dr. Mercola contends highly processed, industrial foods damage the body. To guarantee the body gets the nutrients it requires free from the dangerous chemicals and additions present in processed foods, he advises consuming fresh, organic fruits and vegetables, grass-fed meats, and wild-caught fish. Dr. Mercola emphasizes the need of avoiding preservatives, artificial sweeteners, genetically modified organisms (GMOs), and chemicals that he thinks cause many health concerns including metabolic diseases and digestive problems.

The Discussion on Dairy Intake

Another issue of dispute between Dr. Mercola’s recommendations and accepted wisdom on diet is dairy intake. Although many popular health groups advise dairy as a significant source of calcium and vitamin D, Dr. Mercola has voiced reservations about the possible negative effects of eating traditional dairy products. For those with lactose intolerance or sensitivity to casein specifically, he thinks dairy especially from conventionally bred cows may aggravate inflammation and intestinal problems. As better substitutes, Dr. Mercola advises organic, raw dairy or plant-based choices include almond milk. This is not in accordance with the guidance given by conventional nutrition recommendations, which support dairy as a necessary component of a balanced diet for bone strength.
