Simply eating a large number of two foods with opposite properties may lead to the following three situations:
⑴ Nutrients are antagonistic and mutually exclusive in the process of absorption and metabolism, so that one side hinders the absorption or retention of the other. Such as calcium and phosphorus, calcium and zinc, oxalic acid and iron. Another example is that tofu should not be eaten with spinach, because spinach contains more oxalic acid, which is easy to combine with calcium in tofu to form insoluble calcium salt, which can not be absorbed by human body, but has no clinical symptoms. Of course, if spinach is soaked in boiling water and destroys a lot of oxalic acid, it can also be used to make tofu and become a famous dish at home.
(2) In the process of digestion, absorption or metabolism, harmful substances or poisons, such as vitamin C or foods rich in vitamin C, will be produced if it is not conducive to the decomposition and combination of the body, which may reduce pentavalent arsenic in shrimp to toxic trivalent arsenic, thus causing certain arsenic poisoning.
⑶ * * in the body is both cold and warm, and belongs to nourishing greasy food or fire-dry food. For example, eating a large number of foods that are cold and hot, nourishing yin and strengthening yang is more likely to cause adverse physiological reactions.
Food antagonism is actually a kind of food antagonism. From the analysis of different chemical properties contained in various foods, it is actually the cause of food antagonism, and the principle that causes food antagonism is nothing more than the following three situations:
(1) Chemical association makes some nutrients in food form substances that are not easily absorbed by human body, such as phytic acid, phosphorus, zinc, copper and iron. Forming a metal association; Fat reacts with calcium to form insoluble calcium soap.
(2) Interacting and competing ligands. Mineral elements belonging to the same transport system in the metabolism of food in vivo will have antagonistic effects because of competing for ligands and different affinities with ligands. That is to say, when an element enters the body too much, another element will be excluded from the binding point of the same ligand, and the absorption of the excluded element will also be hindered.
(3) Parenteral factors such as high protein inhibit the accumulation of copper in the liver; High concentration of inorganic sulfate can prevent molybdenum from permeating renal tubular membrane and limit molybdenum reabsorption, thus increasing molybdenum excretion in urine.
In the process of digestion, absorption and metabolism, food antagonism will reduce the absorption and utilization rate of nutrients in food, and lead to the lack of some nutrients in the body over time, resulting in corresponding nutritional deficiency, which will further affect the normal function and metabolism of the body.
In a word, according to the analysis of relevant medical theories, TCM syndrome differentiation and treatment, and the symptoms of intestinal and gastrointestinal reactions of individual patients, it is not nonsense that people do eat each other in their daily diet.
From this point of view, as long as people pay attention to the balanced diet of thick and thin collocation, vegetarian collocation and diverse collocation in their daily diet, rather than fixed partial eclipse, partial eclipse and overeating some foods, it is generally impossible to have food cannibalism. Therefore, the phenomenon of cannibalism cannot be completely denied, and people should not follow suit.
