Joel Fuhrman is a board-certified family physician, researcher, six-time New York Times best-selling author, and internationally recognized expert on nutrition and natural healing who specializes in preventing and reversing disease through nutritional methods. He writes about the importance of nutrient density—abundant in superfoods—in the following excerpt from his book, Fast Food Genocide: How Processed Food is Killing Us and What We Can Do About It.\r\n \r\n\r\nUnderstanding Nutrient Density\r\n\r\n \r\nThere are two kinds of nutrients: macronutrients and micronutrients. Macro­nutrients are protein, carbohydrate, fat, and water. Excluding water, they are the three calorie-containing nutrients. Micronutrients are vita­mins, minerals, and phytochemicals, and they are calorie-free.\r\n\r\n \r\nThe Standard American Diet (SAD) contains too many macronutrients and not enough micronutrients. A micronutrient-rich diet supplies your body with fourteen different vita­mins, twenty-five separate minerals, and thousands of phytochemicals that have a profound effect on human cell function and the immune system. Foods that are naturally rich in these micronutrients are also rich in fiber and water and are naturally low in calories.\r\n\r\n \r\nThe ratio of micronutrients to calories in a food is the nutrient density of that food. \r\n\r\n \r\n\r\n\r\n\r\n\r\nLive Past 100 \r\n\r\nJoel Fuhrman, MD\r\n\r\nJuly 14 - 19, 2019\r\nThe stats are in—during 2018 in the United States alone, there were over 1.7 million new cases of cancer, over 5 million people were living with age-related dementias, and heart disease remained the number-one cause of death. How are you...\r\n\r\nLearn More\r\n\r\n\r\n \r\nGiven the thousands of fragile phytonutrients in a berry or a sprig of broccoli, nutrient intake is more complex than originally thought. You cannot buy superior nutrition with a series of health-food store supplements; colorful plant food is just too complex and complete with beneficial substances, many of which have not even been identified yet.\r\n\r\n \r\nThe secret to a successful, healthy, and happy life is to eat a diet lower in calories and higher in micronutrients. \r\n\r\n \r\nIt’s all about nutrient bang per caloric buck. The nutrient density of your body’s tissues is proportional to the nutrient density of your diet. My “Health Equation” represents this concept of striving for micronutrient adequacy in fewer calories to improve health and life span: H = N/CHealth = Nutrients/Calories.\r\n\r\n \r\nThe SAD does the opposite; it contains lots of high-calorie foods that are deficient in micronutrients.\r\n\r\n \r\nTo achieve superior health and lon­gevity, we must eat more foods that are micronutrient-rich and have fewer empty calories. \r\n\r\n \r\nVery few people are aware of this simple concept, which explains why oils are NOT healthy. They are rich in calories but are virtually devoid of nutrients and fiber.\r\n\r\n \r\nIn addition, eating fewer calories or moderate caloric restriction in the environment of micronutrient adequacy slows the aging process and advances health and longevity. However, what is also convention­ally ignored is that little effort to restrict calories is needed once you consume a diet that is nutritionally superior. When you consume all the high-nutrient produce your body needs, you automatically desire the right amount of calories and no longer feel comfortable eating the amount of food that sustains an unfavorable weight.\r\n\r\n \r\nIn other words, it is actually difficult to remain overweight when your diet is excellent. \r\n\r\n \r\n\r\nThe Top 20 Superfoods\r\n\r\n \r\n1.
