Vitamin D Crucial To Activating Immune Defenses

*

Scientists at the University of Copenhagen have discovered that Vitamin D is crucial to activating our immune defenses and that without sufficient intake of the vitamin, the killer cells of the immune system – T cells – will not be able to react to and fight off serious infections in the body.

For T cells to detect and kill foreign pathogens such as clumps of bacteria or viruses, the cells must first be ‘triggered’ into action and ‘transform’ from inactive and harmless immune cells into killer cells that are primed to seek out and destroy all traces of a foreign pathogen.

The researchers found that the T cells rely on vitamin D in order to activate and they would remain dormant, ‘naïve’ to the possibility of threat if vitamin D is lacking in the blood.

Chemical Reaction that Enables Activation

In order for the specialized immune cells (T cells) to protect the body from dangerous viruses or bacteria, the T cells must first be exposed to traces of the foreign pathogen.

Low Low levels of Vitamin D linked to muscle fat, decreased strength in young

There’s an epidemic in progress, and it has nothing to do with the flu. A ground-breaking study published in the March 2010 Journal of Clinical Endocrinology and Metabolism found an astonishing 59 per cent of study subjects had too little Vitamin D in their blood.

Treatments for Muscle Cramps

Most cases of muscle cramps never get reported to public health authorities, so it’s difficult to say how common they are. But you probably know someone who’s had them.

Study shows soluble fiber boosts immune system

A new University of Illinois study touts the benefits of soluble fiber—found in oats, apples, and nuts, for starters—saying that it reduces the inflammation associated with obesity-related diseases and strengthens the immune system.

“Soluble fiber changes the personality of immune cells—they go from being pro-inflammatory, angry cells to anti-inflammatory, healing cells that help us recover faster from infection,” said Gregory Freund, a professor in the U of I’s College of Medicine and a faculty member in the College of Agriculture, Consumer and Environmental Sciences’ Division of Nutritional Sciences.

This happens because soluble fiber causes increased production of an anti-inflammatory protein called interleukin-4, he said.

The study will appear in the May 2010 issue of Brain, Behavior, and Immunity and is available online.

In the experiment, laboratory mice consumed low-fat diets that were identical except that they contained either soluble or insoluble fiber.
