Excessive consumption of some dietary supplements can reduce life expectancy

Excessive consumption of some dietary supplements can reduce life expectancy

Dr. Fang Fang Zhang, an associate professor at the Friedman School of Nutrition Science and Policy at Tufts University, and her colleagues had explored the effects of dietary supplements on adults living in the U.S. They have gathered data from 27,725 participants who are at least 20 years old, that had signed to be part of the NHANES project. Dietary intake of nutrients from foods was assessed using 24-hour dietary recalls.

High doses of calcium can increase your risk of dying from cancer, and taking vitamin D supplements when you don't need them is associated with early death.

The study used data from more than 27,000 United States adults ages 20 and older to evaluate the association between dietary supplement use and death from all causes, cardiovascular disease (CVD), and cancer.

Another shocking revelation made by the research was that if you are not deficient in Vitamin D but were still taking vitamin D supplements, you could be at an increased risk of death from all causes including cancer.

The objective of the study was stated to be to "evaluate the association among dietary supplement use, levels of nutrient intake from foods and supplements, and mortality among U.S adults".

According to a report in PTI, the research found that supplemental doses of calcium exceeding 1,000 milligrams per day were associated with a lower risk of death, while adequate intakes of vitamin A, vitamin K, and zinc were associated with a lower risk of death from cardiovascular diseases. However, extracting such nutrients and consuming them in the form of dietary supplements confers no such benefit, according to the new study. In addition, people who consume adequate levels of vitamin A, vitamin K, zinc or copper had a lower risk of death from heart disease, compared with those who didn't get adequate levels of these nutrients. There was no cancer death risk increase linked with calcium intake acquired from food rather than pills. It's important to note that the study involved self-reported dietary supplement use and dosage, and it's unclear whether specific usage durations may influence the outcome.

The researchers had a keen observation on the death rates, which were related to intake of foreign Supplements.

Those who reported supplement use were asked the product name, frequency and duration for each nutrient. "It would also be worth exploring whether supplements might be helpful among those who have nutritional deficiencies". The ones that had used supplements had to give more details about it.

As for the finding that high levels of calcium might shorten life, Kumar advises people to get as much calcium from their diet as possible. They say it is always better to consume foods, which are rich in Proteins, Minerals, and Vitamins. But with an abundance of uncertainty and a lack of evidence for supplements, Zhang says the average person should just eat a balanced diet that contains plenty of fruits, vegetables and whole grains, rather than turning to over-the-counter solutions.
