(1) Contaminated food: It can cause food poisoning, such as chemical poisoning, bacterial poisoning, animal and plant poisoning and their toxins. Long-term contact with contaminated food can cause chronic harm, carcinogenesis, teratogenesis and mutation. For example, food contaminated by aflatoxin can cause liver sensation.

Many foods in our daily life contain food additives. Food additives refer to natural substances that are chemically synthesized in food to improve the color, aroma and taste of food and meet the needs of preservation and processing technology. Commonly used food additives are as follows:
(1) Preservatives: such as benzoic acid and its sodium salt, sorbic acid and its potassium salt.
(2) Antioxidants: such as butyl dysprosium mushroom, dibutylhydroxytoluene, gallic acid propionic acid, sodium erythorbate, etc.
(3) Color fixative: such as sodium nitrate (0.5 g/kg) and sodium nitrite (0. 15 g/kg).
(4) Sweeteners, such as sugarcane pond, fructose, glucose and other natural sweeteners. Synthetic sweeteners such as saccharin, sodium cyclamate and sodium cyclamate. (5) odorant, such as sodium glutamate (monosodium glutamate).
(6) Colorants, such as natural colorants such as monascus pigment, turmeric, carotene, and synthetic colorants such as amaranth and yellow fat red.
Are we sure and convinced that the three meals a day we eat are normal staple food and non-staple food, and there is no genetic harm and pesticide herbicide residue? I ate old rice and drank additive drinks in my last life. How many people really care about their health.
Therefore, we must eat reasonably and keep healthy in our daily life.
