    To share with all (especially my fellow gardeners) from the BBC News 4/3/07

    Dirt exposure 'boosts happiness'

    Exposure to dirt may be a way to lift mood as well as boost the immune system, UK scientists say.
    Lung cancer patients treated with "friendly" bacteria normally found in the soil have anecdotally reported improvements in their quality of life.

    Mice exposed to the same bacteria made more of the brain's "happy" chemical serotonin, the Bristol University authors told the journal Neuroscience.

    Common antidepressants work by boosting this brain chemical.



    A lack of serotonin is linked with depression in people.

    The scientists say more work is now needed to determine if the bacterium Mycobacterium vaccae has antidepressant properties through activation of serotonin neurons.

    Lead researcher Dr Chris Lowry said: "These studies help us understand how the body communicates with the brain and why a healthy immune system is important for maintaining mental health.

    "They also leave us wondering if we shouldn't all spend more time playing in the dirt."

    The work could also help experts' understanding of why an imbalance in the immune system leaves some individuals vulnerable to mood disorders like depression, he added.



    Canadian researchers have also been exploring the links between serotonin, mood and immunity.

    A team at Georgetown University Medical Center recently discovered serotonin is passed between key cells in the immune system, and that the chemical can activate an immune response.

    This suggests that serotonin may restore a healthy immune function in people who are depressed and prone to infections.

    On the flip side, it is also possible that serotonin, and serotonin-boosting antidepressants, end up bolstering immunity to the point that they trigger autoimmune disease where the body attacks itself.

    Gerard Ahern, lead researcher on the study, explained: "At this point we just don't know how these drugs might affect immunity, so we really need to clarify the normal role of serotonin in immune cell functioning."

    Thank You for posting this. Very interesting information. I wonder how they figured out the dirt thing in the first place? Maybe I should go out in the backyard and play with some dirt :) Maybe we should all take a few lessons from kids.

    Thanks,

    There are a few indicators that cleaning up our lives has depressed our immune responses.

    Basically, our bodies develop in such clean environments, that they over-react to bugs when they come in contact with them e.g. there is one school of thought that the rise of asthma in recent years is due to the fact that our homes are cleaner. There are fewer dust mites etc, so our bodies are less tolerant when they come into contact.

    Also, there's the idea that some bowel disorders are due to us eliminating bacteria from our environment - hence the need for probiotics to stimulate the growth of "good" bacteria in our gut.

    a high quality soil based organisms product I used in 1999 and just started again a few days ago. My natuopath says I am ready for this after 2 mths of high quality probiotics (10 billion/day)

    This stuff is not cheap but I am becoming ever more convinced that our guts are a major problem for many of us. They say 70% of immunity lies in the gut too. And no I dont sell this product, just posting for informational purposes

    Peace

    What are HSMs?
    Homeostatic Soil Micro-Organisms are highly specialized soil-based organisms that possess powerful health benefits when ingested by humans. They play a vital role in the cyclical ecosystem of healthy soil. HSMs engulf the mould, fungi, and putrefactive bacteria in rotting plant matter. They then transform this waste into nutrients and growth promoting hormones, which they release into the soil to fertilize new plant growth.

    HSMs and Human Health
    The purifying and nourishing effects of these bacteria in soil are duplicated in the human digestive system when HSMs are ingested. Clinical studies have shown HSMs to be capable of dramatically improving intestinal health by reducing intestinal pathogens and by dislodging hardened waste material. As HSMs metabolize undesirable microbes, they release by-products that support human health. In addition, they stimulate the production of self-healing substances and mechanisms (i.e. alpha-interferon, super oxide dismutase, lactoferrin and antibodies). The HSMs' powerful healing potential was discovered in the 1970s. The strain has since been purified, cultivated and tested in clinical trials.

    What are the Therapeutic Benefits of HSMs?
    HSMs improve colon health, immunity, digestion and assimilation, and increase antioxidant levels (super oxide dismutase in particular). They temporarily colonize the intestinal walls, for as long as they are consumed.

    Colon Health
    These fascinating bacteria enhance intestinal health in several ways. They engulf pathogenic organisms such as yeasts, moulds, and putrefactive bacteria. They also burrow into and consume old, hardened fecal material on the intestinal walls, thereby helping dislodge it. And by reducing the populations of antagonistic organisms (most of which produce undesirable chemical by-products), HSMs reduce bowel toxicity. This allows bacteria essential to health, such as Lactobacillus-acidophilus, bifidus, rhamnosus and faecium to thrive. When levels of harmful organisms are high, these bacteria are suppressed. Proper levels of these beneficial bacteria act as powerful immune regulators. They also balance intestinal pH and produce vital hormones, vitamins and enzymes.

    The HSMs also support digestive health by producing short chain fatty acids that help balance the pH of the intestinal tract and support the healing of the intestinal lining.

    Immunity
    HSMs have been shown in laboratory tests to stimulate the human body's production of alpha-interferon and to stimulate an increase in antibody production.

    Alpha-interferon
    Alpha-interferon is a powerful immune compound produced by leukocyte cells. It is well known by the medical community for its effectiveness against moulds, fungi, viruses, and bacteria. For years, scientists have worked to perfect a man-made version of this substance. The synthetic alpha-interferon, currently available is exorbitantly expensive and must be taken in high doses, which can create side effects. Furthermore, artificial alpha-interferon is only able to mimic one sub-species of the 20 that a healthy leukocyte can produce. HSMs, on the other hand, stimulate the production of 16 natural alpha-interferon sub-species.

    Antibody production
    The body reacts to the biomass formed by an HSM colony the same as it does to an antigen (foreign substance) and produces extra B-lymphocyte antibodies in response; these, in turn, stimulate the production of "multi-purpose" antibodies. According to Dr. Peter Rothschild, MD (who has performed extensive research on HSMs), these "multi-purpose" antibodies can be stored and then encoded and used for immune defense as the need arises.

    Digestion and Assimilation
    HSMs have been shown to improve the assimilation of nutrients by improving intestinal absorption, assisting with digestion and releasing lactoferrin (an iron-binding protein).

    Intestinal Absorption
    HSMs act to improve nutrients absorption by removing the barrier created by accumulations of waste on the intestinal wall. As a result of this removal, the intestinal villi, (the hair like "fingers" on the intestinal wall that absorb nutrients), are cleaner and therefore more efficiently absorb nutrients.

    Enzymatic Digestive Supports
    HSMs have enzymatic-like action that supports digestion by helping to break foods down, thereby further enhancing nutrient assimilation.

    Lactoferrin
    Human studies have demonstrated that, as a normal by-product of their metabolism, HSMs release lactoferrin, an iron-binding protein. According to Ann Louise Gittleman, MS, in her book, Beyond Probiotics, humans can absorb up to 95 percent of dietary iron when it is bound by lactoferrin, as compared to 7 percent of non-bound iron.

    Lactoferrin-bound iron is also unavailable to pathogens such as Candida. This is of tremendous benefit to those suffering with the chronic anemia commonly associated with Candida-related illness and other imbalances in intestinal bacteria. Pathogenic intestinal organisms thrive on iron and therefore tend to steal it from their host. Lactoferrin deprives these microorganisms of iron and makes it more available to the host. Adequate iron levels, of course, are essential for immunity, energy, and healing.

    Superoxide Dismutase
    HSMs have been clinically proven to release superoxide dismutase, a powerful cellular antioxidant. This nutrient is well known for its protective effect against free radical induced tissue damage. It is also believed to be protective against carcinogens and radiation.
