A link was found with calcium supplements but not calcium in food
While getting the right nutrients in the right quantities from food was associated with a longer life, the same wasn't true for nutrients from supplements, saysstudy co-author Fang Fang Zhang, an associate professor of epidemiology at the Tufts UniversityFriedman School of Nutrition Science and Policy. 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". Association between dietary supplement use, nutrient intake, and mortality among USA adults: a cohort study.
The study recorded 3,613 deaths in the median follow-up period of 6.1 years.
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". Those that mentioned that they had used dietary supplements had been requested for particulars, together with how typically they took the merchandise. For the survey, interviewers asked participants about what they ate in the last 24 hours, and whether they had taken supplements in the last 30 days.
However, no link was found between increased consumption of foods containing calcium and the disease.
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. Excess consumption of calcium was associated with a higher risk of death from cancer.Food sources of vitamin K include leafy greens such as kale, spinach and broccoli rabe. Researchers then used that information to determine participants' nutrient levels. And eating adequate amounts of vitamins A and K, magnesium and zinc from a food source could also lower death risk. In addition, some past research has indicated that taking supplements - rather than getting the nutrients from food - may increase the risk of certain health problems rather than protect against them.
Instead, the team found indications that use of vitamin D supplements by individuals with no sign of vitamin D deficiency may be associated with an increased risk of death from all causes including cancer.
"This study also confirms the importance of identifying the nutrient source when evaluating mortality outcomes".
Our results support the idea that, while supplement use contributes to an increased level of total nutrient intake, there are beneficial associations with nutrients from foods that aren't seen with supplements. However, more than half of the participants declared the use of dietary supplements, and 38.3 percent claimed the use of multivitamin and mineral supplements.
