In recent years, research has shown that eating large amounts of food containing kojic acid and salicylates, as well as eating food contaminated with condiments, artificial colors and lead, can cause hyperactivity to occur in children with the genetic quality to develop hyperactivity, or make hyperactivity symptoms worse. Huntington’s chorea patients should pay attention to the following points in their diet: 1. They should eat less food containing kojic acid. Such as hanging noodles, pastries, etc. Eat less food containing methyl salicylic acid, such as tomatoes, apples, oranges, etc. Do not add spicy condiments to the diet, such as pepper and so on, and should not use tartar yellow pigment, such as shellfish, big red is, citrus olive and other foods. 2, should eat more food rich in zinc. This is because zinc is a trace element in the human body, and the human body’s growth and development is closely related. Zinc deficiency often makes children’s appetite, developmental delays, and mental retardation. Studies have found that most students with good academic performance have high zinc content in their hair. Therefore, often eat zinc-rich food, such as eggs, liver, beans, peanuts, etc. to improve intelligence will help. 3, should eat more iron-rich food. Because iron is the raw material of blood production, iron deficiency will make the brain’s function disorder, affect the mood of children and aggravate the symptoms of hyperactivity. Therefore, children with ADHD should eat more iron-rich foods, such as liver, poultry blood, lean blood, etc. 4, should eat less food containing lead. Because lead can make children’s visual movement, memory and sensory, image thinking, behavior and other changes, hyperactivity, so children with ADHD should eat less lead-containing eggs, shellfish and other foods. 5, should eat less food containing aluminum. Because aluminum is a kind of metal that threatens human health. Eating too much aluminum can cause mental retardation, memory loss, loss of appetite, indigestion. ADHD children should eat less doughnuts, because the production of doughnuts need to add alum in the flour, and the chemical composition of alum is potassium sulfate. Therefore, eating doughnuts is not good for the intellectual development of children.
