Does sugar increase the risk of cancer?

Myth: Sugar increases the risk of cancer.

There is a long-standing article "The Harm of Teacher Ni's Artificial Sugar" on the Internet, in which the hazards of sugar are enumerated in detail. The article said: Long-term consumption of sugar products will cause fatal cancers such as esophageal cancer and gastric cancer, and sucrose belongs to "alkaline macromolecules", so we should eat sucrose instead of refined sugar.

Interpretation of the truth:

Eating too much sugar is really bad for your health, but saying it causes cancer is a bit like "looking for it if you want to add a crime."

After evaluating the relationship between sugar intake and health, the World Health Organization believes that adding too much sugar will increase the risk of dental caries and obesity. Of course, obesity will also increase the risk of various chronic diseases and cancers, but this is not directly related to sugar, nor is it a pot of sugar alone.

The latest WHO sugar intake guidelines suggest that we should not consume more than 50 grams of sugar every day, and if possible, it is best to control it within 25 grams. It should be pointed out that sugar here refers to free sugar, not sugar naturally occurring in food. Free sugar refers to sugar added to food, including sugar in honey and fruit juice. Sucrose mentioned in this paper is generally used as added sugar. It is not an "alkaline macromolecule" and needs to be restricted. Fructose in fresh fruit, lactose in milk and starch in cereals and potatoes are all sugars existing in natural foods.

Finally, the author of this article, Ni, died on 20 12. Through the introduction of the founder of official website, we can see that he is not a professional who studies food nutrition, but is known as "proficient in classical medicine, numerology, divination and geomantic omen".
