MSG: I am not "a pest"!Updated:2017-02-24    Click:
"Do you want to die? Put too much!" To this day, the "toxic MSG" is still circulating in thousands of kitchens, plagued by countless hands that are reaching out to the can.
The main component of MSG is a substance called glutamate, the standards of food additives in designated "flavor". Usually someone says MSG "toxic" is actually considered "toxic glutamate".
What is monosodium glutamate? In fact, the salt of sodium glutamate. Glutamic acid is an amino acid exists in organisms, the body can be produced, is the communication between the human nerve messenger; sodium, the essential elements of human body, eat salt all know. The two substances together, can make people feel fresh. Monosodium glutamate can use sugar cane, sugar beet, starch as raw materials, a large number of production by bacterial activity, can also be extracted from yeast. In addition, seaweed, mushrooms, tomatoes, beans, meat and other foods naturally contain sodium glutamate. From the beginning of the last century in Japan began commercial production, the human has been more than 100 years of adjustment with monosodium glutamate flavor.
If the above are not enough to have monosodium glutamate then look innocent, the standards of china. Food additives are generally limited to amount of monosodium glutamate, "said China's current standards of all food can according to need to use", "translation" is over "assured". In fact, as early as 1987, the Joint Committee of FAO and the World Health Organization food additives experts have to cancel the provisions of the daily intake of monosodium glutamate name, made 14 years ago (less than 120 milligrams per kilogram of body weight), and allow the baby to take less than 12 weeks. Since then, the United Nations decided not to do the investigation because the intake of sodium glutamate, after years of research, the safety of food additives undoubtedly, was included in the "safe" level.

To take an extreme example, relevant experimental data pointed out that mice given oral sodium glutamate LD50 (LD50) is 16.2 grams per kg of body weight, if this result is extended to a weight of 50 kilograms for adults, is eats a pack a pound loaded MSG is also all right (although feel very bad). It is worth mentioning that the mice oral salt LD50 is 5.25 grams per kilogram of body weight, an adult once eaten a pound of salt, comparable to the risk of monosodium glutamate. Of course, in real life, we will not be so normal daily intake of exaggeration, it can be seen eating MSG to eat poison is too difficult. From the perspective of promoting a healthy diet, the general experts recommend daily intake of monosodium glutamate should be controlled in 6 grams or less, can not control the actual need not be too tangled. Rather than worry about MSG to eat too much, it is better to pay attention to salt, the same to not more than 6 grams per day is appropriate, apparently exceeded the possibility of eating salt exceeded msg.
