Research by many experts in the world has concluded that calcium deficiency is a serious disease that currently threatens humanity. It has caused hundreds of millions of people in the world to suffer from mental and physical torture, which directly affects the improvement of human quality. Experts called for all sectors of the community to pay great attention!
Of the calcium that the fetus gets from its mother, 99% is used to make bones, leaving only 1% free in the form of ionized calcium in the blood called serum calcium. However, the data show that after birth, everyone has entered a different degree of calcium deficiency. People of all ages lack calcium and children and older people are more severe. Scientists have found that since the age of 20, the total weight of bone has been decreasing at a rate of 1% per year, and after 50 years of age, the total weight of bone has been reduced by 30% - this is a scientific and surprising conclusion.
Due to calcium starvation, the so-called calcium removal in the body was caused. That is, the calcium in the bone continuously escapes into the blood to maintain the normal level of serum calcium. The ratio between bone calcium and serum calcium must maintain a long-term balance, otherwise it will produce calcium migration, such an abnormal balance of calcium metabolism. A person’s calcium hunger within a few days or one or two months does not affect serum calcium temporarily, but if this continues, calcium deficiency disorders will occur: Children exhibit hair thinning, anorexia, restless night terrors, rickets, etc.; Skeletal dysplasia, visual impairment, etc.; pregnant women's low back pain, and affect fetal development, and even teratogenic; osteoporosis, bone degeneration, stone disease, hypertension, diabetes, dementia in the elderly and many more.
Obviously, calcium plays an important role in life.
Why do we eat calcium-containing foods every day, such as beans, dairy products, aquatic products, shells, and bones, and the body will suffer from calcium deficiency. It turns out that the calcium contained in food is mostly dissolved calcium salts and is not easily absorbed. Furthermore, when eating with cereals and dishes, the phytic acid contained in the grains or the fatty acids contained in the meat will turn calcium into an insoluble calcium salt and cannot be absorbed. According to the calculation of modern nutrition standards, the biological dose of calcium (referred to as ionized calcium) for adults in China should not be less than 800 milligrams, and the infant should not be less than 1,000 milligrams. It is a pity that for a long time, the medical community calculated that calcium was mistakenly treated as pure calcium (ie, ionized calcium), so that in the past, many medicinal calcium did not provide true calcium supplementation. Fortunately, this fallacy has been discovered in recent years and corrected. A molecular calcium, an ionized calcium, only one word difference, has led to a world-wide human calcium revolution!
Calcium deficiency has calcium, everyone should raise the awareness of calcium, the problem is, what kind of calcium supplement, how to make up? Although for a long time, the medical community recognized that calcium supplementation is a difficult problem, the ideal calcium agent should have three major conditions, namely that 1 contains both high amounts of high-quality pure calcium; 2 can be fully dissolved; 3 is easily absorbed after taking it. ,use. At present, many new, safe and effective calcium nutrition enhancers have been developed that are more and more in line with scientific requirements.
In daily foods, calcium is best sourced from cow's milk and dairy products. It is rich in content and high in absorption rate. It has been found that the calcium content of the shrimp head shell is very high, reaching 2000 mg/100 g, and the solubility is good. It is an ideal calcium supplement for biological protein calcium crystals. It is unscientific to eat shrimp shell meat! Calcium-rich common food, in addition to the above there are beans (soybeans, green beans, black beans and other products), walnuts, sesame, seaweed, kelp and so on.
However, please keep in mind: calcium is best taken one hour before meals on an empty stomach.
(1) Balanced diet is the foundation. The Dietary Guidelines for Chinese Residents formulated by the Nutrition Society proposed to eat milk, beans and their products frequently. These foods have high calcium content. Reasonably arranged balanced meals, where the calcium content can meet the recommended supply standards. The Soybean Action Plan and the Student Milk Program promoted by the State Council are the best ways to supplement calcium.
(2) Prevent calcium from nutrition. In view of the lack of related diseases and the reduction of the degree of osteoporosis in the elderly, there should be sufficient calcium in the diet. After the meal is improved, the insufficient part uses calcium as needed:
(a) Calcium preparations must not contain harmful ingredients. For calcium preparations made from natural shells or animal bones, the use of contaminated raw materials and the avoidance of gastrointestinal irritation should be avoided.
(b) The chemical form of calcium present in the diet does not appear to be a major factor affecting calcium absorption. The subject’s age, physiological condition, retention of calcium in the body, the amount of calcium intake, and other components of the diet (such as protein, phosphorus, etc.) have a greater impact on the absorption and utilization of calcium. In general, the amount of elemental calcium contained in each calcium product and the consumer's affordability for the calcium supplementation program is the reference standard for selecting the type of calcium formulation.
(c) Granules of calcium supplements should be able to disperse and be better absorbed when mixed with foods or after meals; fractionation is more effective than concentration. In the presence of gastric acid, calcium carbonate can also be absorbed. In patients with gastric acid deficiency, organic acid calcium, such as calcium gluconate, calcium citrate and other water-soluble preparations are more easily absorbed.
(d) On the basis of the original calcium level in the food, the dose of supplemental calcium is preferably such that the total amount of calcium in the diet can reach the recommended daily dietary level.
(e) Calcium supplementation is a long-term process and it is impossible to see results in the short term. Studies have confirmed: the twin children and youth in the test
