Е621 is just another name for monosodium glutamate or MSG. This additive is used worldwide because it masks low quality foods, it lowers production costs.
Instead of throwing away certain goods, monosodium glutamate is added to them. Said food becomes tastier, we eat it and can't stop because it's like a drug for our taste buds.
Once having gotten used to foods with glutamate, people can't stop buying them. This is good for food makers, profits increase - it's all business!
For adults, the normal daily value is 1.5 g.
Monosodium glutamate increases appetite, makes people overeat. All this leads to obesity and many other diseases.
In psychiatry it's used to excite cells in the brain. The additive easily gets into the blood, changes our genes and taste sensations. Simply put - they're slowly killing us with the goal of making a profit!
Е621 was discovered by Kikunae Ikeda back in 1907. Through experiments he found that when added to food, MSG improved the quality and taste of low quality meat and frozen products.
Experiments on mice, who were regularly fed MSG, ended with permanent blindness in the animals.
We're eating all sorts of garbage and are being poisoned without a second thought! We have to carefully read the ingredients label on every food product and only then make our choice.
Cook with natural products only and be healthy!
