FRUIT - VEGETABLES CITED IN PROSTATE RESEARCH.

Low fat, plant based diets may help prevent or slow the progression of prostate cancer, according to a new research review. A number of studies, though not all, have suggested that eating plenty of fruits and vegetables may help ward off prostate cancer, while "Western" style diets heavy in animal fat and dairy products may increase a man's risk of developing the disease. In the current study, researchers reviewed 25 previously published studies that examined the effects of plant-based diets on prostate cancer development or progression.

Vitamin D increases life expectancy, study finds

An intriguing new study finds that those who take vitamin D supplements can increase their life expectancies by one to two years.
The study, published in the Archives of Internal Medicine, is just the latest to add to the growing body of evidence that "the sunshine vitamin" is not just good for strengthening bones but also appears to increase survival.
Past studies have suggested that vitamin D deficiencies might be associated with a higher risk of death from cancer, heart disease and diabetes -- illnesses that account for 60 to 70 per cent of deaths in high-income nations.
This study finds that taking extra vitamin D brings health benefits, even in the short term.
This study looked at the results of 18 previously published studies involving a total of 57,311 participants.
Dr. Philippe Autier, of the International Agency for Research on Cancer, Lyon, France, and Sara Gandini, of the European Institute of Oncology, Milano, Italy, analyzed the studies and evaluated doses of vitamin D ranging from 300 to 2,000 international units, with an average dose of 528 international units.
Most commercially available supplements contain between 400 and 1,000 international units.
After an average of 5.7 years, those participants who took vitamin D had a seven per cent lower risk of death than those who did not.
"We had a reduction in all-cause mortality after a follow-up of about six years. So it means that may represent something like an increase of two to three years of your life expectancy," Autier told CTV News.
"With vitamin D, you could say yes, finally, if there is one supplement to take, with all the evidence so far, the best is to take vitamin D -- ordinary doses of vitamin D, not high doses."
The editorial that accompanies the article points out that the study did not consider specific causes of death. The studies were generally short, so the impact of vitamin D was seen on diseases that express themselves in a shorter period of time. For chronic diseases that have a long period of time to develop, the impact of vitamin D would be underestimated by this analysis.
The authors note that it's not clear how vitamin D supplementation lowers death risk. They say it could be that the vitamin inhibits some mechanisms by which cancer cells multiply and grow. Or, it may boost the function of blood vessels or the immune system, they note.
Where the sun don't shine
The editorial notes that vitamin D supplements may simply be compensating for a deficiency that many people appear to have.
"In recent years, an increasing number of researchers from various fields have been arriving at the conclusion that the levels of vitamin D in many people are inadequate for optimal health," the editorial reads.
Heather Chappell of the Canadian Cancer Society says this latest study supports the growing body of evidence of the health benefits of vitamin D. It also supports their recommendations, issued earlier this year, that the entire adult population of Canada begin taking vitamin D supplementation.
"We want to remind Canadians that in Canada, the sun is not strong enough in the fall and winter to produce enough vitamin D. So the Cancer Society recommends that adults start talking 1,000 IU of vitamin D daily.
"The sun's rays become less strong as we move into the fall, so people should start taking a supplement in the fall and winter... probably near the end of September."
Toronto physician, Dr. Linda Rapson says she finds that many of her patients with chronic pain and other ailments are also deficient in vitamin D.
"I have seen people with levels so low that their muscles are weak and they can't get out of a chair easily. After a couple of weeks of taking vitamin D, there is a huge change," she says.
"I think people should be aware vitamin D is essential, that you have to take it. And you don't just take it for a while and you are fine; you have to keep taking it."

Six Simple Tips for Prostate Health

Benign prostatic hyperplasia (BPH) is a noncancerous enlargement of the prostate gland, common in American and European men over the age of 50. While the actual cause is not completely understood, experts believe it is closely linked to hormone levels. Try the following to help reduce the risk of BPH:

Eat a diet low in saturated and trans-fats, focusing instead on the healthier monounsaturated and omega-3 fats.

Eat more whole soy foods. Asian men have a lower risk of BPH and some researchers believe it is related to their intake of soy foods.

Avoid symptom triggers such as caffeine and alcohol, which increase the need to urinate and may irritate the bladder.

Avoid constipation by increasing fiber in your diet. The pressure from constipation may make the symptoms of BPH worse.

Have regular check-ups. The National Institute on Aging recommends that men get regular medical checkups including a prostate exam.

Try Saw palmetto (Serenoa repens). If symptoms of BPH do occur, try managing them with saw palmetto. The best form to use is an extract standardized to 85-95% total fatty acids. Use 160 mg twice a day. Although saw palmetto does not shrink the size of the prostate, it often helps promote healthy function and decreases symptoms.

Consider herbs and nutrients such as green tea extract, stinging nettle root, ginger, rosemary, zinc, lycopene, and selenium. All have been shown to help maintain and promote normal prostate health.

Keep in mind that it may take at least eight weeks of using these supplements before you see a positive change in your symptoms. Be sure to consult your physician and discuss any medications you are taking - including supplements - to avoid interactions.
