Some nutrients, such as magnesium, zinc, vitamins A and K, reduce the risk of premature death, according to a new study. However, it is important that the source of nutrients is natural foods, not supplements.
The latter does not reduce the risk of dying. On the contrary, some may benefit from cancer.
Doses of calcium over 1000 milligrams per day therefore increase the risk of cancer death. The study of 27,000 adults was published in the Annals of Internal Medicine.
Since the potential benefits and injuries of dietary supplements continue to be investigated, some studies have identified relationships between excessive nutritional intake and side effects, including increased risk for certain cancers Fang Fang Zhang of the Friedman School of Nutrition Science and Policy at Tufts University explains. in Massachusetts.
It is important to understand the role of the nutrient and its source for the health effects, especially if the effect cannot be beneficial.
For the connection between nutritional intake and the risk of dying, the researchers found that: A sufficient intake of vitamin K and magnesium was associated with a lower risk of death connected  An adequate intake of vitamin A, vitamin K and zinc was associated with a lower risk of death from cardiovascular disease
Excess calcium intake was associated with a higher risk of cancer death
When evaluating nutrient uptake sources (food vs
- The lower risk of dehydration with sufficient intake of K vitamin and magnesium were limited to nutrients from foods and not from food supplements
- The lower risk of dying from cardiovascular disease was with adequate intake of vitamin A, vitamin K and zinc are limited to food substances, not food supplements
- Calcium intake from supplements of at least 1000 mg / day were associated with an increased risk of cancer death but not associated with calcium intake ag for food
The researchers found that dietary supplements do not affect the risk of death in people with low nutritional intake. Instead, the team found evidence that vitamin D supplements of humans without evidence of vitamin D deficiency may be associated with an increased risk of death.
