What are the disadvantages of eating too much sugar? What happens when you eat too much sugar?

Many foods in life contain sugar. Sweet food will make people feel sweet, and eating it will make people feel better. However, sugar is a taboo for obese and diabetic patients, and it will be harmful for ordinary people to eat too much sugar. So what happens if they eat too much sugar? What are the disadvantages of eating too much sugar?

1, the disadvantages of eating too much sugar

(1) Tooth decay

Many people suffer from tooth decay when they eat too much sugar in childhood. Eating too much candy can cause tooth decay, and often eating candy without gargling in time can easily lead to dental caries (tooth decay) and various oral diseases. Dental diseases and oral diseases will bring a lot of trouble to our diet.

(2) causing anorexia

Eating too much sweets increases blood sugar, inhibits appetite and relies on sweetness. It is also an important reason for some children's anorexia.

(3) Reduce nutrient absorption

Children often eat sugar, especially on an empty stomach, which will destroy the body's absorption of protein and other important nutrients and affect physical development and intellectual development. Dr Harding, a British physiologist, found through experiments that the combination of sugar and protein can change the original molecular structure of protein and turn it into a concentrate, which not only reduces its nutritional value, but also is difficult to absorb.

(4) cause obesity

Sugar is also a nutrient for productivity, which has a great effect on human body. After sugar enters the human body, part of it is decomposed under the action of insulin to supply the energy needed by the human body, and the other part is also synthesized into glycogen under the action of insulin for emergency use. However, there is an upper limit for the human body to synthesize glycogen. More sugar will be converted into fat and stored in the body, which will cause obesity over time, and obesity will cause many chronic diseases, including cardiovascular and cerebrovascular diseases, diabetes, cancer and so on.

(5) cause diabetes

The human body has the ability to recognize. When a large number of sugary foods are ingested, the pancreas will work hard to secrete insulin and break down these sugars into glycogen. If a person often consumes a lot of sugar, insulin will often be overloaded, and every organ of the body has a life span. Overworking will lead to early functional failure and will stop working sooner or later. Diabetes will occur at this time.

(6) causing gout

Too much sugar can easily lead to the formation of endogenous uric acid, while uric acid is too high can easily lead to gout. Gout is really a tormenting disease. It can't kill people, but it hurts people. It has a nickname "Undead Cancer". A survey in the United States shows that the incidence of gout in people who drink a lot of sweet drinks is 120 times higher than that in people who don't drink sweet drinks. It can be seen that the harm of excessive sugar is terrible.

2. How to eat sugar correctly

(1) The sugar intake should not exceed 6 teaspoons per day.

A teaspoon of sugar doesn't sound like much, but it actually has about 4 grams. The World Health Organization suggests that if adults want to keep their body mass index (BMI) within the normal range (18.5~25) and keep healthy, the daily intake of white sugar should not exceed 6 teaspoons, accounting for less than 5% of the total daily calorie intake. It sounds easy, but in fact, many drinks and cakes contain a lot of sugar. For example, a can of soda contains about 10 teaspoon of sugar, which has greatly exceeded the recommended intake. Even according to the American Heart Association's looser standards, women should not consume more than 6 teaspoons of sugar a day, and men should not consume more than 9 teaspoons. To strictly control sugar, you need to quit almost all sugary drinks, cakes and sweets.

(2) China people eat 12 teaspoon of sugar every day on average.

Maybe you think that China people are not as sweet as Europeans and Americans, and they don't have the habit of drinking tea with sugar, so it should be easy to control sugar. However, according to the survey in China in 2008, each person in China eats almost 50g of sugar every day, which is equivalent to 12 teaspoon, which is also higher than the standard of 6 teaspoons. Braised pork, sweet and sour pork ribs, fish-flavored shredded pork and other home-cooked dishes all contain a lot of sugar. Even a spoonful of tomato sauce contains about 4 grams of sugar, and dried meat and bacon also contain a lot of sugar. Coupled with the increasingly westernized eating habits, there are more and more "invisible sugar" in food, and the intake of sugar is getting higher and higher. If you don't consciously control it, it is likely to be comparable to Americans (the average daily intake in the United States is 22 teaspoons).

(3) Sugar control is against nature.

In the process of evolution, in order to get enough calories to survive, sweets were the best choice for our ancestors, so we were born sweet. When we eat sweet things or drink sweet drinks, our brains release serotonin and feel good. Most of our brain cells are affected by serotonin, so our mood, sexual function, sleep, memory, learning ability and appetite are also affected by serotonin. Eating something sweet will really make us happy in all directions. Because of this, drinks with a lot of sugar are so popular. But we must see the crisis under sweetness. Sugary drinks have become our main source of added sugar. Drinking 1~2 cups of sugary drinks every day will increase the risk of type 2 diabetes by 26%, which is simply a chronic suicide.

(4) Syrup is as terrible as sugar.

Many drink shops, such as tea shops, coffee shops or juice shops, use high fructose corn syrup instead of white sugar to increase sweetness. In fact, both of them are as terrible as high calorie and low nutrition. Syrup and sugar are both composed of fructose and glucose, which have the same calories, but syrup is cheaper than sugar, so many businesses prefer to use syrup. Therefore, while beware of white sugar, don't miss high fructose corn syrup, and don't naively think that syrup is a healthy substitute for white sugar.

(5) When shopping in the supermarket, you should stroll along the periphery.

The best way to avoid all "sugar-coated cannonballs" such as syrup and sugar is to refuse all sugary drinks and only buy unprocessed ingredients such as milk, eggs, rice noodles, meat and fish when shopping in supermarkets. These fresh ingredients are generally placed against the wall of the supermarket, while refined foods such as cakes, soda and candy will be placed on the shelves in the middle of the supermarket. We should try to avoid shopping on the central shelf.

(6) Be cautious about sugar substitutes.

Sugar substitute refers to a sweetener with sweet taste but no calories or low calories, which can replace high-calorie white sugar or syrup. However, some sugar substitutes may bring some health risks, such as saccharin, which may lead to bladder cancer. 1977 Although a research report pointed out that the risk of bladder cancer increased obviously after eating a large amount of saccharin, saccharin was not banned and has been used until now because the experimental object was animals and there were no other sugar substitutes for diabetics at that time. For the sake of prudence, it is best not to choose saccharin as sugar substitute. Other sugar substitutes include aspartame, sucralose and neotame, but people still have doubts about the safety of these synthetic sweeteners. Stevioside is by far the most natural sugar substitute, extracted from stevia leaves, and it is a healthy sugar substitute advocated by many people.

(7) All sugar intake must be limited.

Are brown sugar, rock sugar and honey healthier than white sugar, and can they be taken without restriction? The main component of brown sugar and rock sugar is actually sucrose, so it is similar to white sugar, while honey is mainly fructose and glucose. Sucrose, fructose and glucose are actually small molecules, which are easily absorbed by the human body, causing blood sugar fluctuations and bringing burdens to the pancreas, so the intake of these sugars should also be strictly controlled. If you drink a cup of warm water with a spoonful of honey in the morning, you can only eat up to 5 spoonfuls of sugar for the rest of the day.

3. People who can't eat more sugar

(1) Acute infectious diseases

Include influenza, tuberculosis, pneumonia, etc. After these patients eat sugar, the bactericidal effect of white blood cells in the body will be inhibited. The more sugar they eat, the more obvious the inhibition will be, and the more rampant the bacteria will be, which will aggravate the disease.

(2) nephritis

The vascular system function of nephritis patients is damaged, and sugar can promote the disorder of vascular lipid metabolism, so eating more sugar will cause arterial vascular damage, increase the burden of renal artery and affect the recovery of the disease.

(3) Gastropathy

Include gastritis, gastric ulcer, gastric cancer, etc. Gastritis generally has symptoms of acid reflux and pain. Eating sugar will increase stomach acid and aggravate pain, so patients with stomach diseases should avoid eating sugar.

(4) rheumatism

Such patients have a small amount of alkali reserves in their bodies. Eating more sugar will increase the acidic substances in his body and aggravate rheumatism.

(5) Dermatosis

Sugar is converted into fat after metabolism in the body, which increases skin secretion and is not conducive to the improvement of skin diseases; Patients with suppurative dermatosis and seborrheic dermatitis will get worse if they eat more sugar, which is difficult to cure for a long time.

(6) Hyperlipidemia and hypertension

Eating too much sugar will lead to an increase in blood lipid content, which will lead to hypertension and even coronary atherosclerotic heart disease.

(7) Constipation

Sugar can weaken the peristalsis of gastrointestinal tract and aggravate constipation symptoms.

(8) neurasthenia

Eating more sugar will consume the vitamin B 1 that the human body lacks, interfere with the balance of nerve function, and is not conducive to the rehabilitation of diseases.

(9) Hepatitis

How easy it is for hepatitis patients to get diabetes when they eat sugar. Hepatitis not only damages the liver, but also damages the islets in the pancreas. If you eat too much sugar, it will increase the burden of islet and lead to islet failure; Too much sugar will also synthesize neutral fat in the liver, leading to fatty liver and aggravating liver function damage. Therefore, patients with hepatitis should eat sugar according to their illness and follow the doctor's advice. Never "the more the better".

(10) myopia

Too much sugar intake by myopia patients will reduce vitamin B 1 and calcium in the body, weaken the elasticity of the eyeball wall and promote the development of myopia.
