Nutrients from food, not supplements, linked to lower risks of death, cancer

The sample comprised data from 30,899 United States adults aged 20 years old and above.

In 2015, only 12.2 percent of Americans met the recommendations for eating fruit, and just 9.3 percent ate enough vegetables - even though eating enough fruits and vegetables as part of an overall healthy diet reduces the risk of many chronic diseases, including cardiovascular disease, type 2 diabetes, some cancers, and obesity. Meanwhile, excess calcium is shown to increase risk of death from cancer. "This study also confirms the importance of identifying the nutrient source when evaluating mortality outcomes".

"As potential advantages and damages of enhancement use keep on being contemplated, a few investigations have discovered relationship between overabundance supplement consumption and unfriendly results, including expanded danger of specific malignant growths", said Fang Zhang, partner educator at Tufts University in the US.

Excess calcium intake in the context of this study was defined as doses exceeding 1,000 mg a day. 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 USA 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".

But excess calcium from food was not associated with a similar uptick in mortality risk, Zhang says, which suggests that the body may not be able to clear excess supplemental calcium as well as it can natural calcium. Association between dietary supplement use, nutrient intake, and mortality among USA adults: a cohort study.

Its elite force, Saiqa (Lightning), numbers some 3,500, while Haftar's sons also have well-equipped troops, LNA sources say. Allied groups from Misrata down the coast have been moving pickup trucks fitted with machine guns into Tripoli.

During the median follow-up of six years, 3,613 of the study participants died. Nutrients found in foods "can protect us from diseases, so focus on your diet rather than buying supplements".

To calculate the daily supplement dose of each nutrient, the frequency and the product information for ingredient, amount of ingredient per serving, and ingredient unit were combined. Instead, researchers recommend getting nutrients from food.

Nutrients consumed via supplements do not improve health and longevity as effectively as those consumed through foods, according to the study. Too much intake of calcium from supplements is associated with an increased risk of cancer death.

They showed that adequate consumption of vitamins A and K, as well as magnesium and zinc, reduced the risk of death. However, excess calcium was linked to an increase risk of cancer mortality.

'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. In 2011, a large study found that use of vitamin E supplements was linked to an increased risk of prostate cancer in men.
