Since most parts of many animals are edible, there is a vast variety of meats. Meat is a major source of protein, as well as iron, zinc, and vitamin B12. The category of meats, poultry, and fish include beef, chicken, pork, salmon, tuna, shrimp, and eggs. The meat group is one of the major compacted food groups in the food guide pyramid.
Some "minerals" are essential for life, but most are not. [1] [2] [3] Minerals are one of the four groups of essential nutrients; the others are vitamins, essential fatty acids, and essential amino acids. [4] The five major minerals in the human body are calcium, phosphorus, potassium, sodium, and magnesium. [2]
The USDA promoted eight basic food groups prior to 1943, then seven basic food groups until 1956, then four food groups. A food pyramid was introduced in 1992, then MyPyramid in 2005, followed by MyPlate in 2011. Dietary guidelines were introduced in 2015 and slated to be rereleased every five years.
The seven major classes of nutrients are carbohydrates, fats, fiber, minerals, proteins, vitamins, and water. [7] Nutrients can be grouped as either macronutrients or micronutrients (needed in small quantities). Carbohydrates, fats, and proteins are macronutrients, and provide energy. [7] Water and fiber are macronutrients, but do not provide ...
Beans are a great source of fiber, vitamins and minerals like potassium, magnesium and iron—nutrients that many Americans aren't getting enough of, per the Department of Health and Human Resources.
For precise details about vitamins and mineral contents, the USDA source can be used. [1] To use the tables, click on "show" or "hide" at the far right for each food category. In the Measure column, "t" = teaspoon and "T" = tablespoon. In the food nutrient columns, the letter "t" indicates that only a trace amount is available.
[7] Human food can be classified in various ways, either by related content or by how it is processed. [8] The number and composition of food groups can vary. Most systems include four basic groups that describe their origin and relative nutritional function: Vegetables and Fruit, Cereals and Bread, Dairy, and Meat. [9]
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). [2]
