2008 Milk The Origin of the memory is still, by the end of 2009 "problem milk powder" revived, even swept the country during the Spring Festival of Hainan drug cowpea ... ... every year Two "Food security" is a hot topic, but it will happen every year in different types of food safety incidents, in the present that "everybody eats meat afraid of hormones, vegetarian fear toxin, Beverages Afraid of color "in the food environment, how should we respond?
Pesticides toxic to the brain invasion
food safety incidents 2010 2 21: Wuhan City, Hainan Province Agriculture Bureau said the banned pesticide containing cowpea isocarbophos; February 22: Anhui, Hainan drug test showed excessive cowpea triazophos 10 times; February 24: Nanjing Hangzhou, Guangzhou, Shenzhen and Hainan were found in drug cowpea.
toxicity mechanism Toxicology that the number of those who enter with less body, the body tissue with a chemical and physical functions, interfere with or disrupt the normal physiological function, causing temporary or permanent body of the pathological changes of chemical substances, known as the poison. The pesticide is a poison.
Fat-soluble and water-soluble pesticides are two types of water-soluble into the body, may with the urine; and fat-soluble can accumulate in the body. In the intestine, fat soluble pesticides are absorbed into the liver. In the liver that "detoxification facility", there are two important protease: Mixed function oxidase and detoxification enzymes, which can remove a small amount of poison into the body.
Liver detoxification, but there is a threshold, if the intake of pesticides more than this threshold, escape out of pesticides, can enter the blood, accumulate in, and the chemical structure of their affinity fat tissue. Accumulation point today, tomorrow, accumulation point, after a certain amount, would on the body harm people.
Originally, there was something called the blood-brain barrier brain barrier, can prevent invasion of harmful substances in the brain, but the fat-soluble chemicals (eg organophosphorus pesticides), as implicit in the integration into the fat after the body, can be easily penetrated to the brain. If the human brain dry weight, 60% by the fat composition, it became a fat-soluble chemicals in the brain (such as organophosphate pesticides) settled in the Promised Land.
The cowpea identified organic phosphorus pesticide poisoning in triazophos and isocarbophos exceeded, and the organic phosphorus to the brain or central nervous system, and the combination of cholinesterase. Biodegradable acetylcholine esterase, the role of inhibition of nerve excitement, if the role of cholinesterase by organophosphorus was inhibited, will result in the accumulation of acetylcholine in the body, causing over-excited nervous system, there salivation, muscle tremors , sweating and other symptoms, this is a typical example of organophosphate poisoning.
Enrichment of soluble poison in the body with the wet nurse's milk can be discharged, hurt the baby.
proposed 1, balanced Diet Improve the detoxification capacity. Study found that when food lacks essential fatty acids, phospholipids, protein and some vitamins (such as vitamin A, vitamin E, vitamin C, vitamin VB2), and essential minerals (such as zinc, iron, magnesium, calcium, selenium), all allows the body's metabolism of exogenous chemicals transformation change. Animals such as low protein diet can "liver microsomal mixed function oxidase system" activity decreased, affecting the liver's detoxification function.
2, eat-season vegetables grown more difficult because of-season vegetables require more pesticides to fight.
3, in order to reduce pesticide residues in vegetables, repeated washing with water, or the vegetables on the water, Taomi Shui for up to 30 to 60 minutes of immersion
