1. Foods containing lipid peroxides
Lipid peroxides can damage certain metabolic systems, destroy brain cells, and promote premature aging or dementia of the brain. They are commonly found in foods high-temperature fried or exposed to sunlight for long periods, such as smoked fish and roast duck.
2. Foods containing aluminum
Aluminum can inhibit the activity of brain enzymes, leading to a gradual decline in human memory and reduced thinking ability, and even inducing dementia. Alum in fried dough sticks is an aluminum-containing inorganic substance and should not be eaten in large quantities; also, avoid using aluminum cookware to prepare food.
3. Foods containing lead
Lead is a major killer of the brain. When you consume lead-containing foods, such as popcorn, century eggs, and canned foods, lead enters the brain through the bloodstream, causing an insufficient supply of oxygen and nutrients to the brain, damaging brain cells, leading to memory loss, and causing damage to brain tissue.
4. Too sweet foods
An excessive intake of sugar is not easily digested and broken down by the human body. Sugar can seep into the bloodstream, damaging cells throughout the body and making the body's constitution acidic. Therefore, eating less sweets, especially those containing granulated sugar or saccharin, will keep your mind sharp.
5. Monosodium glutamate (MSG) seasoning
The main component of MSG, glutamic acid, produces a nerve-inhibiting substance during human digestion, affecting the nervous system and damaging brain tissue. In particular, infants whose brains are not fully developed and pregnant women should avoid consuming foods seasoned with MSG.
6. High-fat foods
The body requires a large amount of blood to metabolize the fat consumed. Over the long term, this can easily lead to a lack of oxygen in the brain, making thinking sluggish.
7. Foods containing pesticides
Most pesticides are neurotoxic and their long-term accumulation can easily lead to brain degeneration.
8. Overly salty foods
Regularly eating salty foods can damage arterial blood vessels, affecting the blood supply to brain tissue, and keeping brain cells in a state of ischemia and hypoxia for long periods, leading to a decline in memory and premature aging of the brain. The daily salt intake for a normal adult should be controlled to less than 5 grams.
9. Foods containing preservatives and colorings
Some foods are added with preservatives, colorings, and flavor enhancers to improve taste and extend shelf life, and these can also be harmful to the brain. Examples include canned foods, caffeinated beverages, bubble gum, and pastries with artificial colorings. Frequent consumption can lead to problems such as irritability, lack of concentration, memory loss, and slow reactions.
