Calcium tablets increase the risk of heart disease in the elderly

Calcium tablets increase the risk of heart disease in the elderly

Too many people take calcium tablets to strengthen bones and prevent osteoporosis.

But New Zealand researchers say that the strong bones of calcium tablets are not obvious, but they will increase cardiovascular disease in middle-aged and elderly people.

The study was published on July 30th by the online edition of the British Medical Journal.

  Value Added Risk Institute Researchers at the University of Auckland’s Department of Medicine and Health Sciences in New Zealand analyzed about 11 previous studies involving approximately 1.

Data for 20,000 people.

  They found that people who took calcium tablets over the age of 40 had a 30% increased risk of heart disease and a slight increase in the risk of stroke and death.

After eliminating various factors such as age, gender and calcium type, the researchers were still identified as the same.

  The US Health Life website quoted research director Ian Reid as saying on July 30: “When analyzing the comparative experiments, we found that the calcium tablets in the experiment were more likely to have heart disease than the placebo users. the risk increasedThe fracture completely decomposes the positive effect of calcium tablets.

Reed said that 30% is not a big increase in the strict sense, but there are many users of calcium tablets, and the hidden dangers should not be underestimated.

  Lack of effectiveness Reid believes that calcium tablets may increase blood calcium levels, change blood chemical composition, and threaten heart health.

  The researchers said that calcium tablets have little effect on bone health and have little effect on preventing fractures; therefore, it is recommended that middle-aged and elderly people who take calcium tablets to prevent osteoporosis should rethink.

  Dr. John Cleland of the University of Hull in the United Kingdom said in a commentary accompanying the study: “Calcium tablets may not reduce the chance of fracture, and certainly cannot reduce the mortality rate, which can be invalid.

It is unclear whether calcium tablets will actually increase the risk of heart disease or stroke.

However, taking calcium tablets is time consuming and expensive, and people should stop doing so.

Reed and colleagues acknowledged the lack of research, such as the effect of taking vitamin D and calcium tablets at the same time.

  Dietary Reed suggests that people can eat enough calcium in a reasonable and reasonable diet.

“Based on available evidence, we believe that calcium supplements are not good,” he said. People should get calcium from foods such as mineral supplements.

Previous studies have not found that eating certain foods may cause heart problems.

“We recommend that patients give up calcium tablets and switch to foods high in calcium to keep them healthy,” he said. People use bone density to assess the risk of osteoporosis.

“If the risk is high, you should consider using drugs instead of eating calcium tablets.”

  Duffy Mackay, deputy director of the American Nutritional Supplement Manufacturers Association’s Responsible Nutrition Intervention, believes that Reid and his colleagues are untenable because none of the experiments they studied were specifically for calcium.The film is designed with a risk of heart disease.

  McKay recommends that people take 1,000 mg to 1,500 mg of calcium per day from food.

If you do not get enough, you need to take calcium tablets.

He said that calcium tablets should be taken several times a day to prevent calcium levels in the blood from exceeding normal levels.
