Harvard researchers found that in healthy people the risk is reduced by 38%
People who take extra amounts of vitamin D have a lower risk of developing metastases and advanced cancers. This shows a new study by scientists at Harvard University.
According to the study, 17% of patients over 50 who take this vitamin on a daily basis are less likely to develop cancer to fatal levels. And for those of a normal, healthy weight, the percentage increases to 38 percent.

– minerals crucial for maintaining healthy bones, teeth and muscles. But in recent years, experts have discovered that it is involved in a number of segments of the life cycle and growth of many types of cells, including those of the immune system, writes the Daily Mail.
The new study corrects another test from 2018, conducted among 25,000 people. Then a research team concluded that taking extra amounts of vitamin D did not reduce the number of cancer patients. However, over time, cancer deaths have been shown to have decreased among those taking the supplement.
According to the current analysis published in the main scientific journals, this trend is due to the appearance of vitamin D

“Vitamin D is an affordable and inexpensive supplement, we have been using and researching it for years. The current finding, especially the effect against complications and the spread of cancer in people of normal weight, provides new information on the link between this vitamin and advanced cancer, ”said Dr. Polett Chandler, an epidemiologist at the Harvard Women’s Clinic in Boston.

25,000 people,

at 5 years old
Participants included men older than 50 and women older than 55 who did not have cancer when the study began.
The patients were divided into four groups. At first, they were given a daily dose of the vitamin plus omega-3 fatty acids. The second received vitamin D plus placebo. The third is omega-3 plus placebo. The fourth, just a placebo.
Initial results did not show a reduction in the number of cancer patients, but fewer deaths were reported.
At a later stage, Dr. Chandler and her colleagues found that the risk of advanced cancer and metastasis was different in different groups of patients.
1617 of them over 5 years developed invasive forms of the disease, including the breast, prostate, colon and lungs. Among those who took vitamin D, there were 226 cases and 274 among those who took placebo.
In healthy patients, this number was 58 for those who received vitamin D and 96 for those who received placebo, respectively.
An association between omega-3 fatty acid intake and advanced cancer has not been established.
According to the team, being overweight and related inflammatory processes are likely to reduce the effect of vitamin D.
“Our findings, as well as previous research, support the view that vitamin D protects against metastatic cancer. But the role of being overweight needs more research,” said Polette Chandler.
With sufficient amounts of vitamin D, fewer cases of aggressive cancer and a lower risk of death were found. But
exactly what
happens
between this
vitamin and cancer,
oh coronavirus,
It is not yet clear, writes the Daily Mail. In laboratory tests, the use of the vitamin against cancer cells shows that it can reduce their growth and prevent their spread. The additive involved in cellular processes may kill malignant cells, but what happens in test tubes has not yet been shown to apply to the human body as well.
Since 2016, the British health services recommend that everyone take a daily dose of vitamin D of 10 micrograms in autumn and winter.
The advice for people who rarely go out, especially during the quarantine period, is to drink the supplement in spring and summer.
How to get it
Sunlight is the most important source of vitamin D, doctors say. Ultraviolet light in reaction with cholesterol unblocks the production of the vitamin. But people with darker skin have more melanin, which makes it harder for the skin to absorb ultraviolet rays and therefore makes it harder for vitamin D.
We can get the vitamin, albeit in smaller doses, from food. Recommended products include:
– Fish: preferably as fatty as salmon, trout, mackerel, sturgeon, swordfish, sole, cod, herring, sardines, tilapia
– Mushrooms – like human skin, they synthesize vitamin D, but for this they must be exposed to the sun for half an hour before consumption. The most suitable are portobello, crow’s feet, mushrooms, Japanese shiitake
– Milk, including low-fat, soy, almond, rice
– Yogurt, yogurt
– Boiled eggs
– Pork
– Orange juice enriched with vitamins
– Fortified cereals.
