Nutritional Supplements Do Not Work Daily Mail Online



They are usually taken by consciousness healthy, with the hope of adding years to life.

But the study found in the supplementation has little effect, and only nutrients found in foods can lower your chances of death.

some supplements such as calcium and vitamin D were actually associated with a higher risk of developing cancer.

Experts suggest that the results are complemented by growing evidence that supplements can not be used as "insurance" and that diet and lifestyle are key

The study, which focused on more than 27,000 adults in the United States, that certain nutrients in food – but not the day ki – were usually surf & # 39; connected with a lower risk for all causes and for cancer dea

Researchers at Tufts University compared the consumption of a number of nutrients with mortality from all causes, cardiovascular disease and cancer.

They showed that adequate intake of vitamins A and K, as well as magnesium and zinc

But this conclusion was only applied to nutrients in food, and not to supplements.

Scientists have said that people may inadvertently put themselves at greater risk by taking doses of calcium in excess of 1,000 milligrams a day. 19659002] This was associated with a 53% higher risk of death from cancer, although the relative risk remained low.

They found no evidence of a relationship between calcium in food and death from cancer

. Zhang said: "It is important to understand what role the nutritional substance and its source can play in the life-effects, especially if the effect may not be useful.

"Our results support the idea of ​​t, while supplementation helps to increase the overall nutrient intake, there are beneficial associations with nutrients from products that are not seen with supplements.

ADVANTAGES are important for the production of red blood cells that carry oxygen around the body.

Lack of iron can cause anemia.

The Department of Public Health states that most people should be able to get their entire iron intake from the diet.

Good sources of food include:

  • Liver (this should be avoided during pregnancy)
  • Mace
  • Beans
  • Nuts
  • Dried fruits
  • Whole grains [19659026] green leafy vegetables such as feces

How much iron do people need per day?

  • Men older than 18: 8.7mg
  • Women age 19-50: 14.8mg
  • Women older than 50: 8.7mg 19659033] Women with severe periods or pregnant women may require supplements

    Acceptance of iron more than 20 mg per day can lead to constipation, nausea, vomiting and abdominal pain.

    Very high doses can be fatal,

"This study also confirms the importance of determining the source of nutrients in assessing mortality rates."

Sales of additives increased by six percent over the past few years, and the British spent about £ 442 million on them in 2018, according to the Mintel Market Research Group.

Approximately 34 percent of British people daily take supplements, while the figure in the US is approaching 50 percent

. for many years with many studies showing that the additive does not reflect the effects of intake in nature

In this study participants were asked if they used any dietary supplements in the last 30 days

.

Consumption of nutrients from foods was also evaluated using a 24-hour diet list conducted by trained interviewers.

In addition, researchers have found that dietary supplements do not affect the risk of death in people with low intake of nutrients.

Excessive consumption of vitamin D supplements by people without vitamin deficiency may increase the risk of death for any reason, researchers found.

Professor Judy Butriss of the British Food Fund said that the results are added to the growing number of evidence that micronutrient supplements do not reduce the risk of death.

She said: "Dietary research is increasingly considering the effects on health of dietary models rather than on individual nutrients, and it is clear that this is a diet in general and not isolated nutrients in isolation that may have the greatest A beneficial effect on health. "

Professor Tom Sanders of the London College said:" People who are self-medicated with supplements are often "disturbed" or have a health problem. [19659002] & # 39; In addition, there are those who eat low-quality diets but accept the supplement as an insurance policy.

"You can not Putting a bad diet on a good diet with a handful of pills. "

Professor Montgomery of the Institute for Human Health and Disability UCL said:" Any health benefit can be harmful. "[19659002] In the meantime, it's clear that diets with high levels of these components are healthy.

"The addition of some vitamins and / or minerals may benefit those in the risk group (eg, folic acid in pregnancy ) or who may benefit from specific medical reasons (such as osteoporosis).

"In general, those who are otherwise healthy can better focus on consuming a healthy diet rich in vegetables, nuts, seeds, whole grains and fruits, rather than spending money on supplements.

"The latter, as a rule, is not an effective replacement or addition to the first."
