We are constantly looking to preserve the world around us in order to make it a happier and healthier place, but for optimum health, it seems we need to look within.

We may not care to think about it, but we are never actually "alone": our gut plays host to around 100 trillion bacteria, or flora, at any one time, meaning that there are ten times more bacteria than cells in the human body. We are conditioned to be fearful of bacteria, and in some cases this is not without good reason, but not all bacteria are harmful; in fact our health depends on the activity of the "friendly" bacteria that live in synergistic harmony with us inside our intestines.

How much a person eats may be only one of many factors that determines weight gain. A recent study suggests that a breath test profile of microorganisms inhabiting the gut may be able to tell doctors how susceptible a person is to developing obesity.

How you tell if YOU’RE one of those unlucky people? Take a breathalyzer test!

On the LiveScience.com website, Christopher Wanjek reports that doctors say they can smell obesity on your breath, because certain gas-emitting microbes living in the human gut may be responsible for one person’s propensity for gaining too much weight. These microbes can be detected by the presence of methane and hydrogen on our breath.

Think you have gut feelings. Well, they’re real! The gut contains 100 million neurons – more than the spinal cord. Major neurotransmitters like serotonin, dopamine, glutamate, norephinephrine and nitric oxide are in the gut. Also two dozen small brain proteins, called neuropeptides are there along with the major cells of the immune system. Enkephalins (a member of the endorphins family) are also in the gut. The gut also is a rich source of benzodiazepines – the family of psychoactive chemicals that includes such ever popular drugs as valium and xanax.
