Apples are very nutritious, containing a variety of vitamins and acids. When eating an apple, it is important to chew it slowly. This not only aids digestion, but more importantly, it is highly beneficial for oral hygiene and reducing the risk of human diseases. According to experiments by botanists: if it takes 15 minutes to finish an apple, the organic acids and fruit acids in the apple can kill 99% of the bacteria in the mouth. Therefore, eating apples slowly is very beneficial to human health.
As for eating candy, some people take several minutes to eat a single piece, which is a bad habit. This is because there is a type of lactic acid bacterium in the human mouth that ferments sugar to produce acid. The longer sugar stays in the mouth, the more lactic acid is produced, and the greater the likelihood of developing cavities, which is very detrimental to dental health. Therefore, when eating candy, one should try to minimize the time it stays in the mouth. After eating candy, it is best to rinse the mouth with plain water to maintain oral cleanliness.
