Normally, the use of aluminum pots and pans for steaming and cooking is not harmful to human body. However, the long-term use of aluminum pot may cause aluminum elements in the body to retain, when accumulated to a certain extent, the human body has a certain degree of harm, may cause the body lack of calcium, premature aging, digestive disorders, anemia, liver and kidney damage and a series of negative effects: 1, the body lack of calcium: the use of aluminum pot frequency, may cause excessive intake of aluminum elements, aluminum can block the body’s calcium absorption, leading to slow growth and development, osteoporosis and other problems; 2. 2, premature aging: when the body has too much aluminum, can cause oxidative stress in the body, resulting in premature entry of cells into the aging state, and then accelerate the aging of the body; 3, digestive disorders: aluminum in the gastrointestinal tract, can have a certain inhibitory effect on pepsin activity, and then gastric acid secretion will be reduced, and ultimately may cause digestive disorders; 4, anemia. Long-term use of aluminum pot may induce aluminum poisoning, resulting in reduced red blood cell production, some people have dizziness, headache, nausea, vomiting, anemia symptoms; 5, liver and kidney damage: often occur in their own liver and kidney disease, excessive accumulation of aluminum in the body, can intensify the deterioration of liver and kidney function, and even infection, hyperparathyroidism, etc.; 6, neurological degeneration: if the body in excess of aluminum elements invade the brain tissue, may cause mental retardation, memory loss, dementia, children’s mental retardation, etc.
