An Indian study found that compared with healthy adults, the contents of calcium and phosphorus in cerebrospinal fluid of patients with Alzheimer's disease were abnormal.
There are two kinds of minerals in the human body, which are called macro minerals and trace minerals. Among them, a large number of minerals mainly include calcium, phosphorus, magnesium, sodium, potassium, chlorine, sulfur and so on.
When we take a blood test, the report given by the hospital often surprises us. Eating healthily will still lead to calcium and magnesium deficiency. These elements, which are in great need of human body, will do great harm once they are lacking.
Calcium exists in various forms, accounting for 1.4% of body weight. 99% of calcium in human body exists in bones and teeth. But this is not the most important function of calcium. When calcium appears in the blood in the form of ions, it can affect the regulation process of protein.
In addition, the study found that the proportion of calcium and phosphorus in the brain of patients with Alzheimer's disease changed, which led to neurotoxicity. The decrease of calcium ion concentration will lead to the decrease of vitamin D synthesis and the imbalance of parathyroid hormone (responsible for regulating calcium/phosphorus ions) in serum, which will lead to the abnormal accumulation of calcium ions in the brain, promote the formation of neurofibrillary tangles and cause cognitive impairment in the brain.
Insufficient calcium ions in the blood will also affect the permeability of cells, interfere with the normal development and growth of nerve cells in the brain region, and cause symptoms of limb cramps. Insufficient calcium in bones and teeth can lead to osteoporosis and other dental problems. Getting calcium from diet in time is very important for maintaining human bone health and brain health.
The best foods to supplement calcium are milk, shrimp, sesame, fungus, sesame, kelp, laver and black beans.
Phosphorus accounts for 1% of body weight. Like calcium, phosphorus exists in the form of minerals in bones and teeth. Phosphorus also exists in nucleic acids and energy molecules, and is an important component of phospholipids that constitute cell membranes. Under normal circumstances, the ratio of calcium and phosphorus in human body is 2: 1. Phosphorus deficiency can cause abnormal development of bones and teeth, osteoporosis, rickets and loss of appetite.
An Indian study found that compared with healthy adults, the contents of calcium and phosphorus in cerebrospinal fluid of patients with Alzheimer's disease were abnormal. Specifically, serum calcium ion decreased and phosphorus increased slightly. This increase is not simply caused by the increase of age, that is to say, by supplementing food and preventing the abnormal change of calcium and phosphorus ratio in the body, aging and senile cognition can be effectively prevented.
People can supplement phosphorus by increasing the intake of steak, mushrooms, shrimp skin, radish, lotus seeds, scallops and black sesame seeds.
Potassium accounts for about 0.25% of human body weight. The electrochemical balance in human body depends on the positive and negative balance between ions, among which potassium is the most important cation, which is used for nerve conduction and heartbeat regulation. All cells in the human body also need potassium to function normally.
A recent study in Archives of Neurology provides evidence that antihypertensive drugs, especially potassium-sparing diuretics, can reduce the risk of Alzheimer's disease. Another study by Johns Hopkins University researchers confirmed the importance of ensuring the potassium content in the whole circulation to prevent Alzheimer's disease. It is found that the decrease of serum potassium level in middle-aged people will increase the risk of hypertension and stroke, and cardiovascular factors will also increase the risk of cognitive impairment in the elderly. In addition, other normal physiological functions, such as heart, kidney and adrenal function, are closely related to potassium content.
To supplement potassium, besides bananas, you can also eat kelp, laver, sweet potato, spinach, pig liver, coix seed and corn.
Sulfur accounts for about 0.25% of human body weight. Sulfur mainly exists in several important amino acids and is mainly used to construct protein in vivo. Sulfur exists in biotin, protein acid, thiamine and cysteine.
Sulfur can help the human body to produce an important antioxidant-glutathione. Can protect cells from harm. Sulfur also helps to form joint connective tissue. Without enough sulfur, joint pain, acne, arthritis, convulsions, depression, memory loss, rash and other problems will often occur. Sulfur deficiency in the body may also lead to obesity, heart disease, cognitive and chronic fatigue. Sulfur deficiency can lead to pain and muscle and bone diseases related to inflammation.
A study in the journal Nutrition and Metabolism found that if there is not enough sulfur, it will be difficult for the body to remove toxins through the liver. Sulfur deficiency can also cause cells to get insufficient oxygen, which is harmful to normal brain function and cell activity.
If you want to supplement sulfur through diet, beans, garlic, onions, spore cabbage, asparagus, wheat germ, eggs, cheese and fish are all good sources.
Scientists at Cornell University Medical College in new york fed rats a high-sodium diet, which was 4-6 times the recommended salt. Two months later, the researchers found that the blood flow in the hippocampus and cortex of these mice decreased by 25% and 28% respectively. These two areas are the key to determine people's learning ability and memory ability. Three months later, rats fed a high-salt diet developed Alzheimer's disease.
Magnesium accounts for about 0.005% of human body. Magnesium is an important auxiliary factor of enzymatic reaction. Magnesium is also related to the health of teeth and bones.
Dutch 20 17 study shows that too much or too little magnesium intake will increase the risk of Alzheimer's disease. In a study involving more than 9,500 subjects and followed up for 8 years, they found that too much or too little magnesium in the blood would increase the incidence of dementia by 30%.
If magnesium is deficient, consider increasing foods rich in magnesium, including spinach, almonds, cashews, soybeans, black beans, whole grains, yogurt and avocados.
All kinds of minerals are inseparable from health and are very important to ensure the normal operation of muscles, bones and brain. In order to balance nutrition, fruits, vegetables and whole grains are indispensable secrets. If you are not sure whether you are missing any elements, the blood test report of the hospital will show whether the content of elements in your body is normal. According to the test results, it is enough to supplement the elements that the body lacks.
