The oyster belongs to the phylum Mollusca. It ranks among the bivalves in the family Ostreidae.
Like other mollusks, the oyster has appeared in high school.
Oyster consumption goes back, it seems, in ancient times, China and, at the beginning of the Quaternary, on our continent.

The oyster is a product of the sea and this is why she is the receptacle of all the goodness of the sea. Thus, it has restorative and therapeutic qualities indisputable. It is used as a medicine prescribed for children in poor health. It is indeed a source of vitamins, iron, copper and especially iodine, essential to the body.

Oysters are rich in protein and low in calories, fat, cholesterol. It is a food of choice because of its exceptional nutritional benefits but rare elsewhere in the diet.

Oysters are naturally rich in vitamins E, B, D, and to a lesser extent vitamin C (the vitamin C of lemon juice that often accompanies it is negligible). Consumption of oysters with lemon juice also has the defect almost immediately destroy the bulk of vitamin E, contrary to the nature or use vinegar with lemon often preferred by gourmets (and nutritionists) in Because of its lower acidity. Contrary to popular belief, the lemon has no effect on the health standard (it has no effect on potential toxins).

It is often advised not to consume the “first water” present in the shell at the opening that is anyway present in large quantities and contains water refining, sometimes a little sand unpleasant, or may be too salty (in the case of oysters insufficiently refined) or contain a little of their wash water (made prior to the sale in a slightly chlorinated water), which degrades or mask the taste (the more water more likely to still contain the live microalgae, if their washing was not enough, the toxins produced by these algae is causing digestive disorders): once opened, and emptied of the water, the oyster exfiltrate still alive in one or two minutes a purified water sufficient to assess its use and rich in nutrients and easily assimilated minerals.
