Avoid Supplements; Have Natural Foods For Nutrition

A link was found with calcium supplements but not calcium in food

"As potential benefits and harms of supplement use continue to be studied, some studies have found associations between excess nutrient intake and adverse outcomes, including increased risk of certain cancers", said Fang Fang Zhang, M.D., Ph.D., associate professor at the Friedman School of Nutrition Science and Policy at Tufts University and senior and corresponding author on the study. It will even be price exploring whether or not dietary supplements is likely to be useful amongst those that have dietary deficiencies."With greater than half of US adults utilizing dietary supplements, Zhang and her colleagues explored their results, in addition to the impression of vitamins present in meals, with knowledge from 27,725 adults collaborating within the Nationwide Well being and Diet Examination Survey".

More than half of the study participants reported using dietary supplements in the previous 30 days and 38.3 percent reported using multivitamin and mineral supplements.

The study recorded 3,613 deaths in the median follow-up period of 6.1 years.

On the other hand, risk of death from cancer is only associated to excess calcium from dietary supplements, not from food. This includes calcium from supplements. These deaths included 945 deaths from cardiovascular disease and 805 deaths from 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 study used 24-hour diet recall data from six two-year cycles of the National Health and Nutrition Examination Survey, through 2010.

In addition, excess calcium intake was linked to an increased risk of cancer death, which the researchers found was associated with supplemental doses of calcium exceeding 1,000 mg/day. Meanwhile, getting the right nutrients by eating the right amount of food is associated with longer life.

When the team accounted for the nutrient source, they discovered that the reduced risk for death and death from cardiovascular diseases were only associated with nutrient intake from food, not supplements. And in fact, some supplements were linked to increased risk of death. They found that insufficient intakes of magnesium and vitamin K were associated with lower risk of death. There was no connection between dietary supplement use and a lower risk of death. In 2011, a large study found that use of vitamin E supplements was linked to an increased risk of prostate cancer in men. While certain nutrients may contribute to a longer life, they need to come from a food source, the study found.

One thing that the researchers can not say is whether the association is between the nutrients themselves or other components in the foods, Zhang said. Each person provided information about their supplement use in the past month - more than half had used at least one - as well as their dietary habits.
