Probiotics arm immune system against cancer cells and germs

Probiotics arm immune system against cancer cells and germs
The functional foods with probiotics that you can buy in the supermarket make your immune cells attack cancer cells and germs more aggressively. This is apparent from a meta-study published by American researchers in Nutrition Research.

Study
The researchers collected 17 previously published studies, in which healthy people aged 40-84 were given a portion of probiotics every day for 3-12 weeks. In the studies, test subjects received the Bifidobacters or Lactobacilli that you can buy in the supermarket. The subjects usually received the probiotics in the form of functional foods such as yogurt or milk.

Here you will find more details about the studies used.

In the studies, the researchers looked at two types of immune cells: granulocytes and Natural Killer Cells. The researchers had derived those immune cells from the test subjects' blood, and had brought them into contact with germs and cancer cells in test tubes. They then determined how quickly the immune cells switched off the germs or cancer cells.

Results
The use of probiotics enhanced both granulocytes [first figure below] and Natural Killer Cells [second figure]. Those effects were statistically significant.

Conclusion
"Short-term probiotic supplementation enhances cellular immune function in healthy elderly adults," the researchers summarize. "The influence of probiotic supplementation on clinical parameters such as resistance to infection was not evaluated and requires further investigation."

Almost forgot. The researchers were paid by DuPont, a producer of probiotics.

The healthier your lifestyle, the better your Natural Killer Cells function Couple of grams Phellinus linteus daily makes Natural Killer Cells 15 percent more deadly More trees in your area, more Natural Killer Cells in your body

The healthier your lifestyle, the better your Natural Killer Cells function
The Natural Killer Cells are the body's first line of defense against infectious diseases and cancer. How well that defense line functions depends, among other things, on your lifestyle.

Couple of grams Phellinus linteus daily makes Natural Killer Cells 15 percent more deadly
Because we've already bombarded you with posts on the immuno-regulatory properties of mushrooms we thought... we can do it again, no problem.

More trees in your area, more Natural Killer Cells in your body
The most underestimated part of your immune system is that of the innate immune system: the part of your immune system that reacts almost reflexively when a germ enters your body, or if a cell turns into a cancer cell. Natural Killer Cells are key players in this innate immune system.
