The negative effects of taking calcium tablet in overdose.
Introduction of calcium tablet.
Excessive supplement calcium, harmful and unhelpful to the body, if daily dosage exceeds 2000 ~ 2500 milligram calcium, possibly damage kidney function, still can produce other adverse reaction. The main hazards are as follows:
The negative effects of taking calcium tablet in overdose.
Excessive supplement calcium, harmful and unhelpful to the body, if daily dosage exceeds 2000 ~ 2500 milligram calcium, possibly damage kidney function, still can produce other adverse reaction. The main hazards are as follows:
✵1. Excessive calcium supplementation increases the risk of osteoporosis: Studies in western countries have found that calcium does not effectively reduce the incidence of osteoporotic fractures. On the contrary, patients with osteoporosis have a 50% increased risk of hip fracture after taking high calcium.
✵2. Excessive calcium supplementation increases the risk of stone disease: Calcium is not so easy to be absorbed by the body, if intakes too much can not be absorbed, and at the same time intake of oxalate substances(contained in a variety of vegetables, such as spinach), may combine to form calcium oxalate stones, the larger stones can not be excreted with urine, may cause renal colic, severe cases will cause kidney damage.
✵3. Taking too much calcium increases the risk of heart damage: Excessive calcium supplementation may lead to an increase in the amount of calcium in the blood, and hypercalcemia may accelerate the formation of deposits in the arteries, leading to ectopic calcification, and ultimately to the formation of heart disease due to atherosclerosis.
✵4. Excessive calcium supplement affects mineral absorption: Nutrient content in the body needs to be in a stable and balanced state, which is conducive to mutual promotion of absorption, otherwise vice versa. The results show that the absorption of iron, zinc, magnesium, and phosphorus can be significantly inhibited by adding high calcium.
✵5. Hypercalcemia: Early manifestations of hypercalcemia include severe constipation, progressive dry mouth, persistent headache, loss of appetite, irritability, mental depression, metallic taste in the mouth, and weakness. Later symptoms are known including drowsy, fuzzy consciousness, hypertension, arrhythmia, nausea and vomiting, increased urine. It can be seen that any supplements should be understood with two sides, should not only see the goodness.
✵6. Adverse gastrointestinal reactions: Excessive calcium supplementation can stimulate gastric mucosa to promote reflux gastric acid secretion, leading to a large amount of gastric acid and gastric juice secretion, can cause mucosal congestion and swelling, mucosal erosion or ulcer. Excessive calcium can also induce constipation, adverse effects on health.
How to avoid taken excessive calcium?
✵Taking calcium supplements should follow scientific method, calcium tablets are not the more the better, daily calcium intake of about 800 ~ 1500mg is appropriate, not more than 2000mg is appropriate. Eat calcium tablets, and it is better to drink a lot of water at the same time, to promote the discharge of calcium can not be used out of the body, maintain a dynamic balance.
✵ Most calcium tablets on the market are in the form of calcium carbonate and calcium citrate, as well as other forms of calcium such as calcium lactate, calcium gluconate and calcium phosphate. Among these different types of calcium, calcium carbonate is relatively cheap, containing up to 40% calcium, which can only be absorbed better under sufficient gastric acid conditions. It is better to take calcium tablets at the time of eating or shortly after eating, when gastric acid secretion reaches its peak, with a relatively high absorption rate. Calcium citrate is more expensive, calcium content is lower than calcium carbonate, at about 21%. Calcium citrate can also be absorbed without gastric acid, so the elderly gastric acid secretion is less, more suitable for eating this calcium tablet.
✵The calcium absorption rate of Calcium carbonate is the highest, adults use more. However, the body absorbs calcium in a process. Under the action of gastric acid, part of calcium carbonate will turn into calcium chloride and enter the intestine to form calcium phosphate. These calcium salts are difficult to be absorbed and inhibit intestinal peristalsis, which may cause constipation. Especially for the elderly or those lack of dietary fiber in the diet, this situation is more common.
✵Drink some yogurt when taking a calcium supplement, the lactic acid that it contains combines with calcium, can promote calcium absorption. Yogurt also contains a large number of active lactic acid bacteria, can promote gastrointestinal peristalsis, ease constipation. Secondly, the intake of crude fiber should be increased. Vegetables with more crude fiber include dried bamboo shoots, cauliflower, cabbage, cole, etc.; nuts with more crude fiber include black sesame seeds, pine nuts, almonds, etc.; fruits include apple, pear, cherry, jujube, pomegranate, etc.
Infants eat calcium tablets is similar as adults eat junk food.
For ethical reasons, no one tests baby to see how much calcium a human child needs. Scientists only know from animal experiments that the absorption rate of calcium in all kinds of calcium agents on the market, no matter how fancy advertising words are used, is less than 30%, and the absorption rate of calcium in milk powder is more than 80%. There is evidence that breast milk absorbs more calcium than milk powder, leading nutritionists to believe that the total amount of calcium in a baby's breast milk daily equals the amount of calcium a baby needs daily.
For infant calcium supplements, how to understand related truth and its harm?
✵1. Normal breastfeeding infants do not need additional calcium supplements.
✵2. The calcium content of formula milk meeting national standards is higher than that of breast milk, and the absorption rate is higher.
✵3. It is generally believed that the safe medicinal calcium agent is the refined calcium carbonate, which is also the most common calcium tablet at present. Due to its low absorption rate and great stimulation to the digestive tract, it is only suitable for adults who should not eat milk. In fact, calcium carbonate is a common lime, often used in calcium supplements for laying hens and other poultry.
✵4. No matter how fancy calcium tablets get their name, they enter the digestive tract as calcium ions, no more powerful than calcium carbonate.
✵5. Some enterprises like to use oyster shells or calcined oyster shells as calcium, and take the name and call it "natural calcium." In fact, because such shellfish grow in the offshore areas, sometimes they are heavily contaminated by heavy metals(lead, cadmium, etc.), and there is no safety guarantee for feeding children with such shell calcium.
Therefore, calcium tablets are really junk food for baby! Try to let your baby stay away from it.
