British researchers have recently carried out an interesting study, which may contradict the advice some mothers have been giving for years!
They found that certain bacteria contained in soil may have a beneficial impact on people suffering from depression. The study reports that treatment of mice with a “friendly” bacteria, normally found in the soil, altered their behaviour in a way similar to that produced by antidepressant drugs. The results of the report have been published in the the scientific journal Neuroscience.
The scientists first recognised the effect when cancer patients treated with the bacteria reported an unexpected improvement in their quality of life. When investigated further, they now believe the bacteria, Mycobacterium vaccae, may cause an increase in the metabolism of serotonin.
Serotonin is a neurotransmitter that most likely contributes to the regulation of sleep, appetite, and mood. People experiencing depression or anxiety often have serotonin deficiency. Increasing metabolism of the transmitter may help to improve mood, amongst other things.
Future studies will determine if this bacteria found in soil actually has antidepressant properties in practice.

This reminds me of a story my elderly neighbour told me, I think about one of his grandchildren.
The child was fond of playing in the fields around the house, she was always climbing trees, and falling, and their Doctor was visiting, and said about her…” that is the dirtiest,healthiest wean I have ever seen!”
Good “clean” dirt will not do any harm!
Glenn – that’s funny!! My mum always says “clean meat never fattened a pig”!!!
