A large number of calcium supplements are available on the market, and the target consumers are often the elderly, women and children. However, a foreign study has found that excessive calcium supplementation in women increases the chance of coronary heart disease by 25%. If a large amount of calcium is consumed, it may cause damage to the health of the cardiovascular system. Therefore, we should be more cautious about calcium supplementation in women who are not advanced in age, and for those who have been diagnosed with coronary heart disease, it is even more important to avoid it. Long-term calcium supplementation can lead to coronary heart disease? This may be related to the deposition of calcium and phosphorus in the walls of blood vessels. Generally speaking, calcium will be absorbed into the blood through the gastrointestinal tract, and then blood calcium will be formed, and blood calcium will undergo calcium salt deposition and eventually form bones. But this is not one that the more calcium supplementation, the more bones will be formed. Because the blood calcium concentration increases, it will also accelerate the generation of deposits in the arteries, causing vascular sclerosis, thus inducing the occurrence of coronary heart disease. Therefore, it is not the more calcium supplement the better. Daily dietary calcium supplements are safer and more effective Nowadays, many filial sons and daughters buy calcium supplements for the elderly, not knowing that too much calcium may lead to an increased risk of coronary heart disease. In addition, calcium supplements are not easily absorbed and add extra burden to the gastrointestinal tract of the elderly. The safest and most effective way to take calcium supplements should be from the daily diet. For example, eat more calcium-rich foods such as dairy products, shrimp, soybeans and their products every day. Next, choose a healthy lifestyle, drink less or no coffee or cola, and quit smoking. Finally, insist on sunshine and outdoor sports every day, which is also beneficial to calcium absorption and utilization. The elderly should take calcium supplements in moderation and be clear about the usage and dosage of calcium supplements and medications. When in doubt, it is good to consult a professional doctor to avoid excessive calcium supplementation “physical and mental suffering”.
