Why should patients with high blood pressure pay more attention to calcium supplementation?

People with high blood pressure also need calcium supplements, and studies have shown that low levels of calcium in the blood can lead to an increased risk of cardiac arrest. If the body lacks calcium, it will promote the normal contraction and relaxation of vascular smooth muscle, resulting in increased vascular resistance, which may cause blood pressure to increase and cause other complications. Therefore, patients with high blood pressure should take more calcium supplements.

So how should patients with high blood pressure supplement calcium?

The first step is to ensure that the calcium content is at least 300 mg per day, which is the most helpful to maintain blood pressure stability。Most of the calcium is through food, although food contains more calcium, but many people will still be deficient in calcium. This is because the amount of calcium absorbed by people every day is fixed, so calcium supplementation should be done in a method, and not too much at one time, which may also lead to hypercalcemia.

Therefore, if you want to get calcium from food, you should eat some foods with high calcium content, such as soy milk or milk, but some calcium cannot be completely absorbed, but will be excreted, so you should still take an appropriate amount of calcium tablets every day to supplement.

In addition, when supplementing calcium, you must eat less salt, salt will take away most of the calcium in the body, because the kidneys will excrete sodium when digesting, so eat too much salt, the body will take away a lot of calcium when excreting sodium, and the body will be prone to calcium deficiency. In addition, we should eat more fruits, fruits can promote the absorption of calcium, and there is potassium in fruits to reduce the excretion of calcium, so eating more fruits containing vitamin C can promote calcium absorption, and can also increase bone density and avoid fractures.

Soy products are also very good calcium supplements, and soy products are very rich in calcium. If it is made into tofu, its calcium content will be greatly increased, so in addition to soy milk, you can also eat more tofu, in addition to the magnesium and vitamin K in soybeans can promote the absorption of calcium, so you can also eat more soybeans. Eat more green vegetables, such as spinach, leeks, chrysanthemum, and lettuce, which can promote the body's calcium replenishment and effectively control blood pressure.

Because when calcium intake is high, it has a diuretic effect, which can help the excretion of potassium, which in turn can lower blood pressure.

The main reason for this is that patients with high blood pressure are prone to electrolyte imbalance in the body, and supplementing more calcium is also to maintain the electrolyte balance in the body, which is more conducive to controlling blood pressure.

A lack of calcium in the body can lead to high blood pressure, so people with high blood pressure should take calcium supplements. In addition to being rich in high-quality protein and vitamins, milk has a high calcium content and a high utilization rate, containing nearly 300 mg of calcium per 250 ml, so it is a good natural calcium**.

Clinically, it has been found that patients with essential hypertension accompanied by osteoporosis are obviously deficient in calcium, taking calcium and vitamin D, the patient's blood pressure is stable, many people reduce the dose or type of antihypertensive drugs, and patients with mild hypertension in the early stage can even stop taking antihypertensive drugs. After a period of time**, osteoporosis and muscle spasms can be reduced, and the symptoms of osteoarthropathy can be relieved.

Calcium does have a lot to do with essential hypertension. There are calcium ions in human cells, and extracellular fluid calcium ions have different effects from intracellular calcium ions. Calcium ions cannot pass freely inside or outside the cell, and only enter the cell through a special channel called a membrane protein (calcium channel).

Calcium ions need a calcium pump to come out of the cells, and when the concentration of calcium ions in the cells increases, it can activate the muscle contraction system, which causes blood vessels to constrict, resulting in an increase in blood pressure. Calcium antagonists taken by hypertensive patients can bind to the special membrane proteins of the cell membrane, that is, to combine with calcium channels, prevent calcium ions from entering the cell, relax smooth muscle, relax blood vessels, and thus reduce blood pressure. Studies believe that increasing calcium can regulate the central nervous system and sympathetic nervous system, increase the formation of endothelial relaxation factor, reduce the effect of calcium pump activity decline caused by insulin resistance, and reduce the degree of high sodium blood pressure, so calcium supplementation is very beneficial to lower blood pressure.

When the body is deficient in calcium, the secretion of thyroxine increases, which allows calcium from the bones to be released into the blood to maintain serum calcium levels. Parathyroid hormone can also increase the permeability of cell membranes to calcium ions, which promotes the influx of extracellular fluid calcium into cells, and calcium deficiency increases blood pressure. When calcium is adequately supplemented, parathyroid hormone decreases, and extracellular calcium ions are not easily introduced into the cell.

It has been reported that calcium and vitamin D supplementation will not cause arteriosclerosis, and blood cholesterol will be reduced by 6% and LDL by 11% after calcium supplementation, while the amount of HDL will remain unchanged. Calcium supplementation along with vitamin D supplementation can also prevent kidney stones.

Supplementation of appropriate calcium in patients with hypertension is beneficial to blood pressure, and the use of calcium and antagonists at the same time has a synergistic effect on blood pressure lowering, which will increase the antihypertensive effect. However, the primary causes of hypertension are multifaceted, and calcium and vitamin D supplementation should be used in combination with antihypertensive drugs to help maintain blood pressure stability. Moreover, the more calcium supplementation is not better, especially the excessive use of vitamin D can cause toxicity.

A large number of clinical investigations have shown that dietary calcium deficiency is an important factor causing hypertension. Regarding the mechanism of calcium deficiency causing hypertension, Japanese experts believe that it is because the lack of calcium causes hypersecretion of parathyroid hormone, which causes osteolysis to release calcium, and a large amount of calcium enters the blood, resulting in a state called "calcium abnormality". In recent years, Canadian scholars have also believed that about 40% of elevated blood pressure is related to the parathyroid glands.

The parathyroid glands can produce a high-heat-resistant substance, which is the main culprit of high blood pressure, called "hypertensive factor" The reason why a high-calcium diet inhibits high blood pressure is that it can inhibit the production of high blood pressure factors, thereby lowering blood pressure.

Calcium is also inversely correlated with high blood pressure. A lack of calcium in the diet can increase blood pressure. Research data have shown that those with an average daily calcium intake of 450 500 mg are twice as likely to develop hypertension as those with a daily calcium intake of 1400 1500 mg.

Research data have also proved that daily calcium supplementation of 1000 1400 mg can lower blood pressure and restore blood pressure to normal in patients with mild hypertension.

Calcium supplementation can reduce sodium and water retention by increasing sodium excretion. Calcium supplementation can help prevent sodium from elevating blood pressure.

The dietary calcium intake of Chinese residents is lower than that of Western diets. About 2 3 districts have a per capita calcium intake of less than 600 mg per day, leading to an increase in the incidence of hypertension. This is mainly due to the fact that there are few animal foods in China's diet, especially milk and dairy products, and cereals are the mainstay.

Milk contains 120 mg of calcium per 100 grams, while cereals contain 10 30 mg of calcium per 100 grams.

Calcium-rich foods are listed as follows:

Essential hypertension is a common adult disease, in recent years, foreign medicine has done a lot of research on the relationship between hypertension and calcium, and found that patients with essential hypertension have the phenomenon of "three highs and one low", that is, higher intracellular calcium, higher urinary calcium, higher parathyroid hormone levels, and calcium deficiency in the body. If there is too much calcium in cardiomyocytes and vascular smooth muscle cells, the cells are easily excited, causing vasoconstriction and high blood pressure. According to the study of hypertensive people in the United States, under the same nutritional conditions, there are more hypertensive patients in people with low calcium intake, and there are fewer hypertensive patients in high-calcium areas, and the effect of sodium salt in raising blood pressure is more obvious under low-calcium dietary conditions, and when calcium ** is sufficient, this effect is not obvious, in China, the effect of sodium salt in the diet of the population on blood pressure is more obvious than that in Western countries, which may be related to the insufficient intake of ordinary calcium in our population.

Surveys have also shown that for every 100 mg increase in calcium intake per day, systolic blood pressure decreases in Hg levels. Therefore, to prevent high blood pressure, drinking hard water rich in minerals such as calcium and magnesium is beneficial to softening blood vessels and lowering blood pressure.

Therefore, it is not that high blood pressure cannot be supplemented with calcium, but the intake of sodium salt should be reduced in the diet to reduce intracellular sodium retention and reduce smooth muscle excitability. At the same time, a reasonable supplement of a part of the highly absorbed calcium can play a role in lowering blood pressure, and the recommended one here is milk calcium.

Milk calcium is a pure natural active high milk protein calcium extracted directly from milk. Milk calcium is rich in milk minerals, which are naturally extracted from cow's milk**, and the advantages of these ingredients not only provide a balanced nutrient composition, but also promote the absorption and utilization of calcium, such as phosphorus, magnesium, lactose and protein. Calcium in milk calcium in science phosphorus 2:

1. It is conducive to the absorption and utilization of the human body. Because milk is rich in lactose and protein, its absorption rate is much higher than that of other ordinary calcium, and the absorption rate of milk calcium is as high as 62% 70%, which is twice that of calcium carbonate and calcium gluconate, twice that of calcium lactate, and twice that of shellfish calcium. Consumption of milk calcium will not cause flatulence, edema, or constipation.

Milk calcium can be separated and presented in an ionic state without much gastric acid in the human body, and then directly absorbed and utilized by the human body, quickly regulating the blood calcium balance and enhancing physical fitness. Milk calcium is recognized as a food-grade calcium supplement with a high known "bioavailability" of calcium, because milk calcium also contains a moderate amount of protein and a reasonable ratio of calcium to phosphorus2 1;At the same time, because there are no chemical components and processes in its production process, there is no burden on the gastrointestinal tract. Therefore, milk calcium is more suitable for infants, pregnant nursing mothers, children, and the elderly to supplement calcium.

Calcium is one of the most important elements in the human body, is the main component of bones and teeth, and maintains the normal excitability of neuromuscles, participates in the coagulation process of blood, and has important physiological functions such as activating a variety of biological enzymes. Some people say that too much calcium preparation can cause abnormal calcification, aggravate arteriosclerosis and high blood pressure. There is some truth to this.

Therefore, relevant experts believe that patients with hypertension should be cautious about calcium supplementation.

Low calcium is a factor in high blood pressure, so pay attention to calcium supplementation. A simple, safe and effective way to supplement calcium for patients with blood pressure is to choose appropriate foods high in calcium, especially to ensure the intake of milk and its products. 1 sachet of 250ml fresh milk per day is needed for patients with high blood pressure.

If you are lactose intolerant, you can switch to sour milk, soy milk or replace it with lactose-free milk powder.
