As nutrition science has progressed over time, scientists have discovered vitamins, minerals, and other components that make up our foods, and surely, there are more yet to be discovered. Food groups simplify dietary recommendations by focusing on foods instead of nutrients. For example, it’s much easier to try to eat two cups of fruit a day than 75 milligrams of vitamin C and 25 grams of fiber. The USDA Food Patterns provide the recommended amounts of each food group and subgroup at 12 different calorie levels, ranging from 1,000 to 3,200. These patterns are developed using food pattern modeling. By eating recommended amounts, individuals can meet their nutritional needs without having to track dozens of individual nutrients.
