Both sugar and salt are common and indispensable flavoring agents.
And we all know that excessive consumption will induce various health problems - excessive salt, increase the risk of hypertension, cardiovascular disease, osteoporosis; but also increase the burden on the kidneys, damage to the gastric mucosa and so on.
And "sugar addiction is more harmful than smoking", too much sugar will accelerate aging, affect intelligence, damage vision, induce obesity...
Although many people have now begun to consciously control their sugar and salt intake for health. But did you know that there are actually more terrible "health killers" around us than the two!
1 Put more MSG
Monosodium glutamate and chicken essence are seasoning agents often used in cooking to improve freshness, and in order to increase the taste of food, many people like to put more.
But there are also people who think that MSG will cause cancer, can not eat, choose chicken essence is better... Are these ideas really right?
1 Chicken essence and MONOS, the main ingredients are the same
In terms of chemical composition, both are composed of sodium glutamate, both have the effect of fresh seasoning, and the function is not much different.
However, the sodium glutamate content of chicken essence is less than that of monosodium glutamate, and on the basis of monosodium glutamate, additional chicken or chicken bone powder, spices, inosinic acid, guanylic acid, chicken flavor, starch and other substances are added to make it more delicious.
2 MSG is not carcinogenic, but eating more is not beneficial
At temperatures above 120 ° C, sodium glutamate will become sodium pyroglutamate, but there is no evidence to prove its carcinogenicity, but it will lose its umami taste.
However, although MSG is non-toxic and harmless, it contains a lot of salt, if you eat MSG at the same time do not reduce the intake of other sodium salts such as table salt, it is easy to exceed the sodium standard.
A high-sodium diet can easily lead to obesity and may also increase the risk of diseases such as type 2 diabetes, high blood pressure and coronary heart disease.
3 Proper use is safe
(1) Put it before cooking
Sodium glutamate is not easy to dissolve at room temperature, and it is best dissolved at 70 ° C ~ 90 ° C, and the umami taste is the most sufficient.
Therefore, whether it is stir-frying or stewing, it is not advisable to put MSG and chicken essence too early, but should be put in when the pot is out.
(2) Add vinegar without MSG
When cooking sweet and sour fish, sweet and sour pork ribs, vinegar boiled cabbage and other foods, it is best not to add MSG and chicken essence.
Because MSG is heated in acidic foods, it is easier to produce sodium pyroglutamate, which makes the dish taste bad.
(3) Control quantity
The safe intake of glutamate for humans is 30 mg 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 one-third of the amount of beer caps.
When cooking, you can also add chicken juice soup, mushrooms and other freshness to reduce the use of seasonings such as monosodium glutamate.
2 Excessive intake of food additives
In order to extend shelf life, improve quality, increase nutrients, etc., basically processed foods (such as carbonated drinks, ice cream, preserved fruits, preserves, hamburgers, canned food, etc.) will have food additives.
However, such food additives, as long as they do not exceed the scope, are added in full accordance with the prescribed limited use, which is basically harmless to human health.
However, some additives are found in many foods, and if you are not careful, you will overdose.
1 Ubiquitous fructose syrup
From milk tea, beer, and juice to ketchup, bread, and instant cereal, there are fructose syrup, and it can be said that it is really everywhere.
Fructose syrup has cold and sweet characteristics, high solubility, full of fruit aroma, but also anti-corruption, low cost, so it has an unshakable position in the field of food processing.
But excessive intake, its harm is also the greatest of all additives!
(1) Cause fatty liver and diabetes
Fructose syrup in food and beverages is liquid fructose, which, when ingested, is absorbed by the human body at the fastest speed.
Fructose catabolism is carried out in the liver, excessive intake of fructose, will promote liver overload, long-term so easy to lead to fatty liver; people are prone to insulin resistance after obesity, resulting in diabetes.
(2) Induce gout
Fructose metabolism in the liver produces purine groups, the final product of purines is uric acid, too much uric acid accumulation and crystallization, will form tophi.
Therefore, long-term consumption of foods containing fructose glucose syrup additives may also cause hyperuricemia and increase the risk of gout.
2 Exogenous added propionic acid that destroys metabolism
Dairy products, ham sausages, bread, cakes, instant noodles, these familiar foods due to the production, preservation, transportation and preservation of flavor needs, it is inevitable to add some preservatives, and propionic acid is the most commonly used class of preservatives.
Microorganisms in the human colon can break down dietary fiber to produce propionic acid, and as a short-chain fatty acid, it can regulate immunity, improve systemic inflammation, and reduce cardiovascular damage caused by high blood pressure.
However, exogenous propionic acid, added to food, has a completely different effect on the human body.
A report published in the American journal Science Translational Medicine said that exogenous propionic acid may cause obesity and insulin resistance.
Researchers at harvard public health institutes and other institutions conducted a controlled trial of 14 healthy people, and the subjects were randomly divided into two groups, one group added 1 gram of propionate to their meals and the other group added a placebo.
The results showed that shortly after eating, the levels of hormones such as norepinephrine and glucagon in the blood of the subjects in the propionate group increased significantly.
This proves that propionate may act as a "metabolic disruptor," potentially increasing the risk of diabetes and obesity in humans.
3 The more you eat the more "stay" trans fatty acids
Trans fatty acids are more resistant to high temperatures, not easy to deteriorate and can improve the water retention of products, increase the crunchiness of food, thereby prolonging the shelf life of food, so they are widely used in the raw materials for making various types of biscuits and pastries, including vegetable cream, margarine, shortening, salad dressing, cocoa butter and so on.
And these "artificial" trans fatty acids are a non-essential fatty acid in the human body, and excessive intake will cause great harm to health!
A study published in the international journal Neurology suggests that trans fatty acids may be risk factors for all-cause dementia and Alzheimer's disease. In addition, it also increases the viscosity of the blood, which can easily cause atherosclerosis and blood clots.
Therefore, for the sake of health, it is best to eat less refined foods, choose more natural, less processed foods, and control the amount.
