b complex loss vitamin weight

It is carried out either in the kidneys, in reptiles and birds, or the liver, in mammals and perching birds. The last enzyme in the process, l-gulonolactone oxidase, cannot be made by humans because the gene for this enzyme is defective Pseudogene ΨGULO.

The loss of an enzyme concerned with ascorbic acid synthesis has occurred quite frequently in evolution and has affected most fish; many birds; some bats; guinea pigs; and most primates, including humans. The mutations have not been lethal because ascorbic acid is so prevalent in the surrounding food sources it may be noted that many of these species diet consists largely of fruit.

For example an adult goat will manufacture more than 13,000 mg of vitamin C per day in normal health and as much as 100,000 mg daily when faced with life-threatening disease, trauma or stress. Trauma or injury has been demonstrated to use up large quantities of vitamin C in animals, including humans.

It was only realised in the 1920s that some cuts of meat and fish are also a source of vitamin C for humans. The muscle and fat which make up the modern western diet are however poor sources.

As with fruit and vegetables cooking degrades the vitamin C content. Vitamin C is present in mothers milk and in less amounts in raw cows milk but pasteurized milk contains only trace amounts of the vitamin [30].

The following table shows the relative abundance of vitamin C in various foods of animal origin, given in mg of vitamin C per 100 grams of food: It is important to choose a suitable method of food preparation that conserves vitamin C content. When cooking vegetables, one should seek to minimize temperature and duration of cooking and not discard water used in preparation e.g., by steam cooking or by making soup.

Food source vitamin C is identical to that in supplements. The structure of vitamin C is well understood, see ascorbic acid, and there is no difference in benefit between natural and synthetic forms although fruits and vegetables contain various other nutrients, and vitamin C is not their only health benefit.

Recent observations suggest that the impact of temperature and cooking on vitamin C may have been overestimated: It also appears that cooking doesnt necessarily leach vitamin C in all vegetables at the same rate; it has been suggested that the vitamin is not destroyed when boiling broccoli.[40] This may be a result of vitamin C leaching into the cooking water at a slower rate from this vegetable. Copper pots will destroy the vitamin.[41] Some research shows that fresh-cut fruit may not lose much of its nutrients when stored in the refrigerator for a few days.[42] Vitamin C enriched teas and infusions have increasingly appeared on supermarket shelves.

Such products would be nonsense if boiling temperatures did indeed destroy vitamin C at the rate it had previously been suggested. It should be noted however that as of 2004 most academics not directly involved in vitamin C research still teach that boiling temperatures will destroy vitamin C very rapidly.

Vitamin C is the most widely taken dietary supplement.[43] It is available in many forms including tablets, capsules, drink mix packets, in multi-vitamin formulations and as chemically pure crystaline powder. Tablet and capsule sizes range from 25mg to 1500mg.
