What is the Truth About Fructose Raising or Lowering?

Using sugar substitutes is an alternative for sugar lovers. Fructose, known as the "sweetest natural sweetener", is also mistaken for a safe sugar by many people because it comes from nature.

Is this the truth? Fructose is a monosaccharide, an isomer of glucose, with the molecular formula C6H12O6. It exists in a large amount in fruit juice and honey in a free state, and fructose can also combine with glucose to form sucrose.

There are many natural fructose products on the market, all claiming that their products are 100% extracted from fresh fruits and vegetables, and will not directly affect insulin secretion and glycemic index, so diabetics can eat them with confidence. Is it really?

1. The truth of fructose "hypoglycemic"

Starting from lychee disease: some people have symptoms such as dizziness, sweating, pale complexion, fatigue, palpitation, thirst, and hunger after eating a lot of fresh lychees. , and even symptoms such as convulsions and sudden coma.

why? It was later discovered that these symptoms were all a reaction to hypoglycemia. In our understanding, lychees are high-sugar fruits. Why do low blood sugar still occur after eating fruits with high sugar content?

It turns out that there is a hormone called insulin in our body, and its main function is to lower blood sugar. And his secretion is also affected by sugar, which means that when the sugar in the blood suddenly increases, it will be secreted rapidly.

Therefore, if a large amount of litchi is eaten at one time, the invertase is in short supply, and the fructose cannot be converted into glucose in time. In addition, the α-methylenecyclopropylglycine contained in the seeds of lychee has the effect of lowering blood sugar, thus leading to the occurrence of lychee disease. If you eat more lychees and reduce your meal intake, it will aggravate the occurrence of hypoglycemia.

This is why fructose also "lowers blood sugar", which is not only short-lived, but can also pose a very high risk to the health of people with diabetes.

2. Too much fructose is harmful

Eating too much fructose not only increases your risk of obesity, but it also dulls your insulin response, which can lead to diabetes, a new study shows.

In recent years, the medical and academic circles have paid more and more attention to the harm of corn syrup, fructose, and sucrose to the body. Many people believe that these additional sweeteners are likely to cause problems such as obesity and insulin resistance.

Numerous studies suggest that the health risks mentioned above may be caused by the additional sweeteners that people add.

Researchers at the University of Colorado School of Medicine conducted experiments on mice and found that the liver can convert glucose into fructose, and such mice quickly developed obesity and insulin resistance if they ingested additional glucose.

Published in the journal Nature Communications, the study found that not only is fructose from the diet, but the liver also makes fructose from carbohydrates that don't contain fructose, and that fructose made in the body increases Fatty liver, insulin resistance risk.

In fact, fructose does harm the body, and eating high-glycemic foods will also increase the body's fructose concentration, so it is not advisable to eat more high-glycemic foods.
