Sugar is refined sugar from cane and beet molasses squeeze made. Sugar in the production, packaging, transportation, storage process, it is easy to contaminate the pathogenic microorganisms. Especially to store more than one year, the color yellow sugar, often contaminated meats. According to the experiment, from 500 grams of sugar, he even checked out 15,000 mites. If people eat sugar was contaminated mites, parasitic mites enters the digestive tract, causing abdominal pain, diarrhea and other symptoms, and some even cause allergic reactions. If the infant or elderly foods directly into the pollution raw sugar, probably due suffocation and other mites into the lungs and cause asthma or hemoptysis, complicated by bronchitis or pneumonia and easily.

Sugar, divided into two categories, namely, sugar, white sugar and cotton. White sugar is sucrose crystals, generally more than 99.8% purity, from a chemical point of view, this is a very pure substance. White sugar has a pure sucrose sweetness, in addition to direct consumption, but also the main varieties of industrial sugar. Cotton, sugar, cane sugar is fine grains are wrapped in a layer of invert sugar syrup made of, its purity and white sugar considerably. Here invert sugar plays a soft, flavored, functions as a co sweet. This is because the invert sugar having a honey-like scent (the main component of honey is invert sugar) which is greater than the sweetness of sucrose (sweetness of sucrose is 1, the conversion of sugar sweetness 1.2), invert sugar than the ability to maintain a strong absorption of sugar pills soft, so soft sugar taste better than white sugar. Soft white sugar optimum direct human consumption, it is preferred to eat cold drinks cold, but not used to make advanced pastries.

Sugar is one of the main source of nutrition for the body, the body’s consumption of thermal energy produced should be maintained after glucose oxidation, the energy needed by the body activity by about 70% of the sugar supply. Sugar nutrients, but should be controlled within a certain number range. In the end how much sugar a person the right of foreign opinion more consistent day to eat are: daily per kilogram of body weight control in about 0.5 grams. That is, the weight of 20 kg per day for children less than 10 grams, 60-kg adult, about 30 grams per day. So, usually to grasp the amount of sugar in food, in order to avoid over-feeding.
