Why does eating sugarcane easily cause mouth ulcers?

There are several main reasons why eating sugarcane can easily lead to mouth ulcers: 1. High sugar content: Sugarcane contains about 18–20% sugar, primarily glucose and fructose, which are readily absorbed and utilized by the body. Excessive sugar intake may promote bacterial growth in the mouth, creating conditions favorable for the development of oral ulcers. 2. Coarse and tough fibers: Sugarcane has thick, hard fibers that can easily scratch the tongue and oral mucosa during consumption, causing wounds. These injuries may develop into mouth ulcers under bacterial influence. 3. Nutritional imbalance: Although sugarcane contains nutrients such as vitamin B1 and vitamin B2, excessive consumption may lead to nutritional imbalances, negatively affecting the health of the oral mucosa. When consuming sugarcane, it's important to do so in moderation and maintain good oral hygiene habits.
