Joel Furhman

Joel Fuhrman is an American celebrity doctor who advocates what he calls a "micronutrient-rich diet". His practice is based on his nutrition-based approach to obesity and chronic disease, also referred to as a nutritarian or restrictive diet, as well as promoting his products and books. He has written several books promoting his dietary approaches including the bestsellers Eat to Live, Super Immunity, The Eat to Live Cookbook, The End of Dieting (2016). and The End of Heart Disease (2016). He sells a related line of nutrition related products.

Fuhrman was born in New York City, on December 2, 1953. He is Jewish. He was a competitor in the amateur figure skating circuit. He was a member of the US World Figure Skating Team and placed second in the US National Pairs Championship in 1973. In 1973, he suffered a heel injury which prevented him from competing. Fuhrman claims that an alternative medicine therapy recommended by a naturopath helped speed his recovery, and led him to become interested in alternative medicine.

He came in 3rd place at the 1976 World Professional Pairs Skating Championship in Jaca, Spain, skating with his sister, Gale Fuhrman, but due to short-term massive muscle loss from fasting was unable to make the Olympic team. In 1988, he graduated from the University of Pennsylvania School of Medicine. Fuhrman is a board-certified family physician and serves as Director of Research for the Nutritional Research Foundation.

Fuhrman has advocated eating at least one pound of raw vegetables and another pound of cooked vegetables each day with an emphasis on green vegetables along with beans, onions, mushrooms, berries, nuts and seeds. He also recommends eating at least one cup of beans a day to benefit from the resistant starch and increased satiety. The Nutritarian diet does not allow dairy products, animal products, snacks between meals, fruit juice, oils or processed foods.

Fuhrman popularized the notion of nutrient density in what he calls the Health Equation: Health = Nutrients/Calories (abbreviated as H = N/C). Peter Lipson, a physician and writer on alternative medicine, has been heavily critical of Fuhrman's health equation, writing that since its terms cannot be quantified, it is "nothing more than a parlor trick". Fuhrman created what he calls the "Aggregate Nutrient Density Index" or ANDI, a ranking of foods based on his claims of micronutrient concentration and kale is at the top of this list. 

Whole Foods began using the scores as a marketing project and reported that the sales of high scoring foods "skyrocketed". David Gorski has commented that Fuhrman has promoted a vitalistic view of food and the pseudoscientific idea of detoxification. Fuhrman has heavily marketed his products and his infomercials have "become a staple during the self-improvement bloc of PBS pledge drives."

In the October 2012 edition of Men's Journal, Mark Adams stated that Fuhrman "preaches something closer to fruitarianism or Christian Science than to conventional medical wisdom". Adams also reported that Fuhrman believes that the flu vaccine "isn't effective at all". Dietician Carolyn Williams has described Fuhrman's nutritarian diet as a fad diet. According to Williams "This can be helpful for people who feel stuck in their weight loss journey and want to totally reset or detox their diet following a holiday or vacation. 

Although this diet is marketed as an eating pattern, it is essentially a fad diet. Those who do try this diet should go into it knowing that it is not sustainable for everyone long-term, and is only a temporary quick fix to lose weight." Harriet Hall who reviewed Fuhrman's nutritarian diet commented that he tends to incorrectly assume association studies show causation and that his diet has not been tested in controlled trials. Hall stated that "Fuhrman makes extraordinary claims for the Nutritarian diet, but extraordinary claims must be supported by extraordinary evidence, and the evidence he presents is far from compelling."
