The increase in antioxidant capacity of blood seen after the consumption of anthocyanin-rich foods may not be caused directly by the anthocyanins in the food, but instead by increased uric acid levels derived from metabolizing flavonoids (anthocyanin parent compounds) in the food. [52]
Folate naturally found in food is susceptible to destruction from high heat cooking, especially in the presence of acidic foods and sauces. It is soluble in water, and so may be lost from foods boiled in water. [122] For foods that are normally consumed cooked, values in the table are for folate naturally occurring in cooked foods.
Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. [1] Poor nutrition is a chronic problem often linked to poverty, food security , or a poor understanding of nutritional requirements. [ 2 ]
Inulin-containing foods can be rather gassy, especially for those unaccustomed to inulin and these foods should be consumed in moderation at first. [citation needed] Inulin is a soluble fiber, one of three types of dietary fiber including soluble, insoluble and resistant starch. Soluble fiber dissolves in water to form a gelatinous material.
Because they are soluble in water, excess B vitamins are generally readily excreted, although individual absorption, use and metabolism may vary. [7] The elderly and athletes may need to supplement their intake of B 12 and other B vitamins due to problems in absorption and increased needs for energy production.
Dietary fiber is defined to be plant components that are not broken down by human digestive enzymes. [1] In the late 20th century, only lignin and some polysaccharides were known to satisfy this definition, but in the early 21st century, resistant starch and oligosaccharides were included as dietary fiber components.
Space-filling model of nicotinic acid. Nicotinic acid, [a] or niacin, [b] is an organic compound and a vitamer of vitamin B 3, an essential human nutrient. [4] [5] It is produced by plants and animals from the amino acid tryptophan.
Riboflavin, also known as vitamin B 2, is a vitamin found in food and sold as a dietary supplement. [3] It is essential to the formation of two major coenzymes, flavin mononucleotide and flavin adenine dinucleotide. These coenzymes are involved in energy metabolism, cellular respiration, and antibody production, as well as normal growth and ...
