Health guide to spring and summer: The all kinds of delicacies are really so nutritious-
A lot of people thought the nutritive value related to price, so " does not ask best, it is most expensive to only ask " . In fact the price only subjects to the domination of economic law of the market, have nothing to do with the nutritive value. Gluttonous and expensive abalone, just in order to obtain satisfaction of taste and psychology. Needn't feel sorry to eat low priced razor clam and spiral shell's clam,etc. either to the person who afford to eats the abalone. " all kinds of delicacies " No matter its content composition of amino acid, or vitamin, inorganic salts or microelement,etc., there are very high places. And in the course of processing and drying, through the multiple process, the nutrient component is being destroyed constantly. So, pursue " all kinds of delicacies " blindly Really a high value of the price is not high. Bird's nest. The bird's nest is the nest of the esculent swift. The esculent swift begins to make the nest in spring, can secrete in its oral cavity out a kind of colloid saliva, spat out, dried up by the sea wind, turn into a semitransparent but pale yellow -tinged material, this is principal ingredients of a bird's nest. " bird's nest " Maintain the skin the good merchantable brand, first-class tonic at Chinese medicine, in terms of nutrition of Western medicine, its protein content 49.9%, not so good as the crab of the equal quantity, proteins included are mainly the collagen, belong to the not complete albumen, in this sense, the nutrition value of the bird's nest can not compare with the egg, meat. The carbohydrate content is 30.6%, not as the cereal of the equal quantity his fat content is 0.3%, not so good as meat of the equal quantity, soybean,etc. too, so the bird's nest does not have very high nutritive value. Shark's fin. The shark's fin is taken from the cartilage cartilage fish's fins such as the shark,etc., per hectogram of shark's fin (dry product) China includes 83.5 grams of proteins, 0.3 grams of fat, 146 milligrams of calcium, 194 milligrams of phosphorus, 15.2 milligrams of irons. The reason why everybody think shark's fin nutrition costly, because nutrient component of shark's fin collagen and chest amine sour mainly mainly, and there are these materials. His collagen quantity is it would be better pigskin, cow hide large, there is the sour content of amine of chest too in a lot of animal cartilages are organized. In a sense, the nutritive value of the shark's fin can not even compare with the pork, beef, because the collagen that the shark's fin includes lacks a kind of amino acid ' Tryptophane) ,It is incomplete protein, the absorption rate to this kind of incomplete protein human body is very low, difficult to digest. Bear's paw. Also called Xiong Fan, it is the soles of a black bear, brown bear. From seeing the poultry, domestic animal compared with nutrition of several kinds of wild animals, they are very nearly the same in major indicators such as protein, carbohydrate, energy,etc.. The fat of bear's paw is abundant, contain more smooth muscle and collagen, but from the viewpoint of nutrition, in food such as sheep's muscle, ox's muscle, duck's palm, chicken's tendon, pig's trotter, contain the same composition too, only their appearance is smaller than the bear's paw. The nutritionists have made an analogy, if 30 ducks slap equal to weight of a bear's paw, it will not be second to a bear's paw to eat up 30 pieces of nutrition which ducks absorbs after slapping. As the saying goes, " fish and bear's paw can't hold concurrently and have " ,Selected the fish or selected the bear's paw on earth? In fact, form and have comparing from fat and protein, the nutrient component of the fish is closer to the human body. Because contain essential many kinds of unsaturated fatty acid of human body in the fish, can prevent in the emergence fish of vascular disease of the heart brain effectively amino acid of protein included forms and is very close than with the human body, absorption rate and biological utilization ratio of all kinds of nutrient are higher. And the collagen contain rich amount of in the bear's pawed, it is difficult to be digested and assimilated by the human body. In this sense, fish nutrition surpasses the bear's paw.
