More “horrible” than sugar and salt, you probably eat it every day……

Sugar and salt are common and indispensable flavorings.And we all know that eating too much can lead to all kinds of health problems.Excess salt increases the risk of high blood pressure, cardiovascular disease, osteoporosis, increased kidney burden, damage to stomach mucosa, etc.And “sugar addiction is worse than smoking”, too much sugar will accelerate aging, affect intelligence, damage eyesight, induce obesity…Although many people have started to consciously control their sugar and salt intake for the sake of health.But you know, in fact, there are hidden around us more terrible than the two “health killer”!Too much MSG
Monosodium glutamate (MSG) and chicken essence are often used in cooking to improve the flavor of fresh, and in order to increase the taste of food, many people like to put more.But some people think MSG can cause cancer, can’t eat, choose chicken essence better…Are these ideas right?Chicken essence and MONOsodium glutamate, the main ingredients are the same
In terms of chemical composition, both are made of monosodium glutamate, and both have the function of fresh flavor, with little difference in function.The content of monosodium glutamate in chicken essence is less than monosodium glutamate, and on the basis of monosodium glutamate, chicken or chicken bone meal, spices, inosinic acid, guanylate acid, chicken flavor, starch and other substances are added to make it more delicious.MSG doesn’t cause cancer, but eating too much won’t help
Glutamate turns to pyroglutamate at temperatures above 120 ° C, but there is no evidence of carcinogenicity, except that it loses its umami taste.But although MONOsodium glutamate is non-toxic and harmless, it contains a lot of salt. If you eat monosodium glutamate without reducing the intake of salt and other sodium salts, it is easy to exceed the sodium standard.A high-sodium diet is linked to obesity and an increased risk of diseases such as type 2 diabetes, high blood pressure and coronary heart disease.It is safe to use correctly
① Put it in before serving
Monosodium glutamate is not easily dissolved at room temperature, and is best dissolved at 70℃ ~ 90℃, with the best umami taste.Therefore, whether it is cooking, or stew soup, should not be prematurely put MSG, chicken essence, and should be put in the pot.② Add vinegar, not MSG
When cooking sweet and sour fish, sweet and sour spareribs, vinegar center cabbage and other food, had better not put MSG, chicken essence again.Because MSG is heated in acidic food, it is easier to produce sodium pyroglutamate, making dishes stale.(3) to control the amount of
The safe intake of glutamate for humans is 30 milligrams per kilogram of body weight per day.For a healthy adult of 60 kg, this equates to no more than 1.8 grams per day.That’s about a third of a beer bottle cap.Peacetime cooking, can also add chicken juice soup, mushrooms and other fresh, reduce the use of MSG and other seasonings.Eating too many food additives
In order to extend the shelf life, improve the quality, increase the nutritional composition, etc., basically processed food (like carbonated drinks, ice cream, preserved fruit, preserves, hamburgers, canned food, etc.) will have the existence of food additives.However, this kind of food additive, as long as not beyond the scope, completely in accordance with the provisions of limited use to add, to human health is basically harmless.But some additives are found in many foods and can be consumed in excess.The ubiquitous high fructose corn syrup
From milk tea, beer, juice, to tomato sauce, bread, ready to eat cereal, high fructose corn syrup can be found everywhere.High fructose corn syrup has the characteristics of cold and sweet, high solubility, full fruit flavor, but also can prevent spoilage, low cost, so it has an unshakeable position in the field of food processing.But excessive intake, its harm is also the biggest of all additives!① Cause fatty liver and diabetes
High fructose corn syrup (HFCS), found in foods and beverages, is a liquid fructose that is absorbed by the body at the fastest rate after ingestion.Fructose catabolism is carried out in the liver, excessive intake of fructose, will make the liver overload work, so easy to lead to fatty liver for a long time;People are prone to insulin resistance after obesity, resulting in diabetes.② Induce gout
Fructose is metabolized in the liver to produce purine groups, and the final product of purine is uric acid. Excessive accumulation and crystallization of uric acid can form topout.So long-term consumption of foods containing HFCS additives may also cause hyperuricemia and increase the risk of gout.Exogenously added propionic acid that disrupts metabolism
Dairy products, ham sausages, bread, cakes, instant noodles, these familiar food due to the production, preservation, transportation and maintain flavor needs, will inevitably add some preservatives, and propionic acid is the most commonly used preservatives.Microbes in the human colon can decompose dietary fiber to produce propionic acid, which, as a short-chain fatty acid, can regulate immunity, improve systemic inflammation and reduce cardiovascular damage caused by hypertension.However, exogenous propionic acid, which is added to food, has a completely different effect on the human body.Exogenous propionic acid may contribute to obesity and insulin resistance, according to a report published in the journal Science Translational Medicine.Researchers at Harvard School of Public Health and other institutions conducted a controlled trial of 14 healthy people, who were randomly assigned to a diet supplemented with 1 gram of propionate or a placebo.The results showed that shortly after the meal, blood levels of hormones such as norepinephrine and glucagon rose significantly in the propionate group.This suggests that propionate may act as a “metabolic disruptor,” potentially increasing the risk of diabetes and obesity in humans.The more you eat the more stupid trans fatty acids
Trans fatty acids are more resistant to high temperature, not easy to go bad, and can improve the water holding capacity of products, increase the crispness of food, and thus prolong the shelf life of food. Therefore, they are widely used in the raw materials of various biscuits and cakes, including vegetable butter, margarine, shortening, salad dressing, cocoa butter substitute and so on.And these “artificial” trans fatty acids, is a kind of non-essential fatty acid, intake of too much, can cause great harm to health!Trans fatty acids may be a risk factor for all-cause dementia and Alzheimer’s disease, according to a study published in the international journal Neurology.In addition, it will increase blood viscosity, easy to cause atherosclerosis and thrombosis.Therefore, for health, it is best to eat less processed foods, choose more natural, less processed foods, and control the amount.BTV I am a big doctor, science popularization China editor: Wang Yitong shangguanhao author: Shanghai Putuo
