White sugar is refined sugar made from molasses squeezed from sugar cane and sugar beets. White sugar is white, clean and sweet. White sugar can easily contaminate pathogenic microorganisms during production, packaging, transportation, and storage. In particular, white sugar that has been stored for more than a year and whose color turns yellow is often contaminated by roundworms. According to the experiment, 15,000 locusts were detected from 500 grams of white sugar. If a person eats the white sugar contaminated by the mites, the mites enter the digestive tract and cause symptoms such as abdominal pain and diarrhea, and some may even cause allergic reactions. If such contaminated raw white sugar is directly added to the food of an infant or an elderly person, it may cause asthma or hemoptysis due to coughing or the like, thereby causing bronchitis or pneumonia.
Sugar is a nutrient but it should be controlled within a certain amount. How much sugar a person eats in one day is appropriate. The more consistent opinion abroad is that the daily weight per kilogram is controlled at about 0.5 grams. In other words, a child weighing 20 kg does not exceed 10 grams per day and an adult weighing 60 kg has about 30 grams per day. Therefore, it is usually necessary to grasp the amount of sugar in food so as not to overfeed.
