Xiao Wu, 35, has always had headaches in the past year and his memory has declined a lot, but he doesn’t pay attention to it. It was not until one night that he got lost and didn’t come back all night. His family sent him to the hospital for examination. As a result, he was diagnosed as
. Alzheimer’s disease is a kind of brain degenerative disease, which is usually related to age. Why is it that young people are not safe? The doctor speculated that this might be related to the fact that the patient insisted on eating breakfast for more than ten years
in the past ten years, the breakfast of the patients was fried dough sticks almost every day, and the puffing additives used in the fried dough sticks contain a lot of aluminum, such as alum, baking powder and soda, which may cause long-term excessive aluminum intake.
aluminum is an element that the human body does not need. When a large amount of aluminum is not metabolized out of the body, it is easy to slowly deposit in the body and cause damage to the brain!
brain tissue has a certain affinity for aluminum, so excessive aluminum is more likely to deposit in the brain, and has a toxic effect on brain nerve cells, causing pathological damage such as neurofibrillary tangle and degeneration and necrosis of nerve cells in the brain, resulting in brain aging, memory loss, behavior retardation, intelligence decline, etc.
relevant animal experiments have found that aluminum can be directly measured in the brain of rats after drinking water treated with aluminum salt. And the relevant hospital detection also found that the aluminum content in the brain tissue of Alzheimer’s disease patients was 5-30 times higher than that of normal people.
as early as 1989, the World Health Organization listed aluminum as one of the sources of food pollution, suggesting that the daily intake of adults should be controlled below 0.004 G. Although there are no aluminum expanders, most of the puffed food such as steamed bread, cakes, bread, biscuits, potato chips, shrimp chips and other puffed foods still use aluminum containing expanders, fermentation agents or food additives, so it is necessary to control the consumption of aluminum.
and some non regular food production may have the problem of excessive aluminum content. The aluminum content of every 100 grams of food can reach more than 100 mg. We must pay attention to distinguish.
there is a layer of dense oxide film on the surface of aluminum cookware, which is stable and safe under normal circumstances. However, due to the surface of aluminum products is easy to be scraped off, it is not ruled out that aluminum element spills out occasionally.
especially after the solution containing strong acidity or alkalinity is stored, the oxide film is destroyed, and many aluminum elements may be mixed into food. It is suggested that aluminum cooking utensils should not be used or used less, and stainless steel, glass, ceramics and other materials can be used instead.
in January 2012, a study was published in the journal. After tracking and measuring 137 patients with mild cognitive impairment for an average of 9 years, it was found that amyloid beta protein, the main substance that induces Alzheimer’s disease in the brain, has begun to accumulate in 5-10 years before the onset of the disease.
there are more than 6 million Alzheimer’s patients in China, and the average age of Alzheimer’s disease has gradually advanced from 65 years old to 55 years old, which indicates that brain degenerative diseases have a trend of youth.
but at the same time, it should be noted that long-term excessive mental work may also lead to brain fatigue syndrome, which causes the accumulation of many harmful substances such as free radicals produced by metabolism in the brain, blocking the nutrient channels, resulting in the decrease of blood oxygen content, poor blood circulation and brain cell activity, and finally accelerate the aging of the brain.
teenagers, people with heavy work and mental workers are prone to brain fatigue. According to a survey in Shanghai, 80% of white-collar workers who work late into the night may suffer from brain fatigue, with memory disorders, language errors, fatigue and facial numbness.
long-term insomnia, anxiety, depression, stress, mental stress, etc., are easy to make people enter the stress state, and secrete adrenaline, and enhance the activity of gamma secretase, thereby promoting the formation and accumulation of brain harmful substances such as beta amyloid, and increasing the incidence rate of Alzheimer’s disease.
3. High incidence of chronic basic metabolic diseases, such as hypertension, hyperlipidemia, diabetes, etc., may cause blood viscosity of cerebral capillaries, decrease of oxygen saturation, frequent inflammation of vascular wall, and even induce cerebral hemorrhage or cerebral infarction.
only when the brain is in deep sleep can it clean harmful substances through cerebrospinal fluid. Studies have found that in people who stay up all night, beta amyloid protein in the brain can increase by 5%, and accumulate in the right hippocampus, which is in charge of short-term memory.
even during the day, the possibility of amyloid beta protein aggregation is three times higher than that of normal workers, so it is difficult to make up for the damage to the brain caused by staying up late.
nicotine in cigarettes can activate the acetylcholine receptor of the brain, stimulate the nerve to continue to excite, and has strong addiction. Long term smokers, leaving cigarettes will lead to mental depression, dizziness, headache, mental retardation and other adverse reactions, and cigarettes are easy to induce DNA mutations.
there are other reports that alcohol can paralyze the nerve center and cause conduction block. Some people who drink alcohol for a long time still have atrophy of cerebral cortex, and the cerebral cortex is a very important physiological functional area. Once damaged, it will have adverse effects on exercise, diet, thinking and sense organs.
brain aging is something that everyone must face, and the physiological decline is difficult to reverse, but we can try our best to delay brain aging. Two things are very important.
1. The brain needs five kinds of nutrition. Good nutrition is the basis of brain health. Each of these five kinds of nutrients has its own use, so we should take it appropriately.
glucose is the only energy required for the normal operation of the brain. 250 ~ 400g of cereal and potato food can meet most of the daily needs. However, high blood glucose level will also damage cerebral blood vessels. Therefore, it is necessary to supplement certain dietary fiber to regulate blood glucose, such as oats, green leafy vegetables, fruits, beans, etc.
after brain aging, the ability of blood vessels and brain cells to metabolize oxidation products of free radicals is reduced, and excessive free radicals will accelerate aging. Therefore, supplementing foods rich in vitamin E and vitamin C, such as broccoli, carrots, grapes, soybeans, tomatoes, etc., will help to resist oxidation and enhance memory function.
high quality fat can not only strengthen brain tissue structure, but also help self repair and renewal, especially omega-3 fatty acids. EPA and DHA among them can regulate blood lipid and blood pressure, and protect nerve and cerebrovascular health. The main food sources include salmon, tuna, flax oil, rapeseed oil, wheat germ, eggs, nuts, etc.
tryptophan can generate 5-hydroxytryptamine, which can make people feel happy, relax brain pressure and ensure good sleep. Tryptophan rich foods are mainly millet, walnut, bean curd, laver, black sesame and so on.
lack of water can lead to blood viscosity in the brain, which can easily reduce the efficiency of oxygen delivery, thus causing loss of mental power and memory. Therefore, we should ensure that daily drinking water is not less than 1000 ml, and more water should be added in hot weather.
