Macronutrients, especially protein, fat and carbohydrates, have been the focus components of the study of (human) nutrition since the 19th century. Until the discovery of vitamins and vital substances, the quality of nutrition was measured exclusively by the intake of nutritional energy .
In 2008, 35% of adults above the age of 20 years were overweight (BMI ≥ 25 kg/m 2), a prevalence that has doubled worldwide between 1980 and 2008. [112] Also 10% of men and 14% of women were obese, with a body mass index (BMI) greater than 30. [113]
Not only does a nutrient-rich diet provide the vitamins, minerals, fiber, antioxidants, and macronutrients (protein, fats, and carbs) needed, but it also supports healthy weight management. A few ...

This study found that a high percentage of people with type 2 diabetes tend to be deficient in three micronutrients: vitamins D and B12 and magnesium. These are also commonly deficient nutrients ...
These macronutrient intakes fall within the Acceptable Macronutrient Distribution Ranges (AMDR) for adults identified by the Food and Nutrition Board of the United States Institute of Medicine as "associated with reduced risk of chronic diseases while providing adequate intakes of essential nutrients," which are 45–65% carbohydrate, 10–35% ...
Macronutrients are defined as a class of chemical compounds which humans consume in relatively large quantities compared to vitamins and minerals which provide humans with energy. Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g).
