With the rise of fitness and weight loss fever, sugar substitutes are favored by young people. Now many drinks, biscuits and snacks advertise themselves as? 0 sugar 0 card 0 fat? . Look at the ingredient list. Most of them have added sugar substitutes. Sugar substitute has been controversial since its birth. Whether it is healthier than ordinary sugar depends on the situation. Sometimes, long-term consumption of sugar substitutes is more harmful than you think.

1, eating sugar substitutes for a long time may have side effects. Studies have found that long-term consumption of sugar substitutes will increase appetite, thus consuming more energy and increasing the possibility of obesity. Sugar substitute is suitable for diabetics and insulin resisters because it will not cause the blood sugar of human body to rise. Of course, healthy people can also eat it, but it may lead to decreased insulin sensitivity and disorder of blood sugar metabolism after a long time. In addition, long-term consumption of sugar substitutes may also destroy the balance of intestinal microorganisms and weaken the digestive ability. At the same time, it affects the normal secretion of neurotransmitters and easily leads to negative emotions such as anxiety and depression. Therefore, we should be careful to eat sugar substitutes, be careful not to overdo them and try to avoid eating them for a long time.

2. Sugar substitutes are addictive. Sugar replacer is considered as a substitute for sugar because it can combine with the sweet receptors of our tongue taste buds, making the brain mistake it for sugar, which leads to? Is it sweet? This feeling. Among them, artificial sweeteners such as saccharin, aspartame and sucralose are many times sweeter than sucrose, for example, aspartame is 250-350 times sweeter than sucrose; Saccharin is more powerful, and its sweetness is 300-500 times that of sucrose. However, sugar substitutes can't really satisfy people's desire for sweets, and they will want to eat again after eating. And eating these sugar substitutes for a long time will make the brain dependent on high sweetness.

3. Affect insulin secretion: Although sugar substitute will not stimulate the increase of blood sugar level, obesity and diabetes can be completely controlled by replacing natural sugar with sugar substitute, and no better effect can be obtained. If a large amount of sugar substitutes are ingested, the body will over-secrete insulin after sensing the sweetness signal. Long-term stimulation will lead to decreased insulin sensitivity, reduced lipolysis and increased synthesis, which is not conducive to controlling obesity and diabetes. Affect the metabolism of liver and kidney: because sugar substitutes do not contain natural sugar, they need to be decomposed by liver and kidney and excreted. If the intake is large, it may also affect the metabolism of liver and kidney. In addition, sugar substitutes are mostly added to processed foods, but there are many preservatives and additives in processed foods, which may also affect liver and kidney metabolism after long-term consumption; Stimulate taste buds: sugar substitutes need to stimulate taste buds on the tongue to achieve sweetness. If you eat too much, it will stimulate the taste buds. If it is to lose weight and control diabetes, it is not recommended to completely replace natural sugar with sugar substitutes. Instead, we should control diet and moderate exercise, and scientifically control weight and blood sugar by reducing energy intake and increasing energy consumption.
