Vitamin D, Omega-3, and Exercise Can Effectively Protect the Elderly: Healing Practice

Measures to prevent cancer: risk decreases by 61%.

A simple combined treatment of high doses Vitamin D, omega-3 fatty acids is one training program can older people according to a large international study effectively protect against cancer.

researchers of University of Zurich reports that a combination of high-dose vitamin D, omega-3 fatty acids and a simple home exercise regimen Reduce the risk of cancer in healthy adults over 70 by up to 61%. candies. The findings were recently presented in the journal Frontiers in Aging.

Cancer prevention needs to be improved

After heart disease, cancer is the second cause of death. The risk of developing cancer increases with age. Simple preventive measures to protect against cancer are therefore of great importance for public health.

However, currently available offers for cancer prevention they are quite limited. “For middle-aged adults and the elderly, they are now largely limited to screening and vaccinations.”underlines the dean, prof Heike A. Bischoff-Ferrari.

Three simple steps to protect yourself from cancer

As part of the so-called DO-HEALTH study, the working group led by Bischoff-Ferrari has now for the first time examined the combined benefit of three simple and inexpensive measures to prevent cancer: Vitamin D, Omega-3 and exercise.

  • Studies in recent years have already confirmed that vitamin D inhibits the growth of cancer cells.
  • Omega-3 supports this process by slowing the transformation of normal cells into cancerous cells by fatty acids.
  • Physical activity improves immune function and reduces inflammation, which often underlies cancer.

Are the measures complementary?

To date, however, it has not been examined whether the effects of the individual measures complement each other. This knowledge gap has now been filled. The international research team tested the effectiveness of the combined measures on 2157 participants from five European countries.

The risk of cancer decreased by 61%.

Evaluation of the three-year study showed that daily intake of high-dose vitamin D3 in combination with omega-3 fatty acids and implementation of an exercise program in healthy people over the age of 70 significantly cumulative jobs.

Each measure already has an effect in itself. If all three measures were combined, it decreased Cancer risk in subjects for a total of 61 percent.

The group found that they had the lowest cancer risk received daily 2000 IE Vitamin D3 And one gram of omega-3 fatty acids. In addition, the participants drove Independent strength training three times a week through home.

High security at low cost

“Although our findings need to be replicated in a long-term and even larger study, the three measures already qualify due to their high safety and low cost to reduce the high cancer burden in the elderly.”, summarizes Bischoff-Ferrari. (vb)
