Acceptable Macronutrient Distribution Ranges (AMDR), are a range of intake specified as a percentage of total energy intake. Used for sources of energy, such as fats ...
These include: 2 grams per day of plant stanols or sterols and 10–25 grams per day of soluble fiber. Macronutrient Distribution of the TLC Diet. The Therapeutic Lifestyle Changes macronutrient profile includes: Total fat: 25–35% of total calories; Saturated fat: Less than 7% of total calories; Polyunsaturated fat: Up to 10% of total calories
Fat has a food energy content of 38 kilojoules per gram (9 kilocalories per gram) proteins and carbohydrates 17 kJ/g (4 kcal/g). [ 2 ] Water makes up a large proportion of the total mass ingested as part of a normal diet but it does not provide any nutritional value.
Some nutrients can be stored – the fat-soluble vitamins – while others are required more or less continuously. Poor health can be caused by a lack of required nutrients, or for some vitamins and minerals, too much of a required nutrient. Essential nutrients cannot be synthesized by the body, and must be obtained from food.
In the United States, the Institute of Medicine publishes a system of Dietary Reference Intakes, which includes Recommended Dietary Allowances (RDAs) for individual nutrients, and Acceptable Macronutrient Distribution Ranges (AMDRs) for certain groups of nutrients, such as fats.
In 2006 the typical American diet was about 2,200 kilocalories (9,200 kJ) per day, with 50% of calories from carbohydrates, 15% protein, and 35% fat. [7] 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 ...
The digestion products consisting of a mixture of tri-, di- and monoglycerides and free fatty acids, which, together with the other fat soluble contents of the diet (e.g. the fat soluble vitamins and cholesterol) and bile salts form mixed micelles, in the watery duodenal contents (see diagrams on the right).

Each gram of fat when burned or metabolized releases about nine food calories (37 kJ = 8.8 kcal). [5] Fats are also sources of essential fatty acids, an important dietary requirement. Vitamins A, D, E, and K are fat-soluble, meaning they can only be digested, absorbed, and transported in conjunction with fats.
