Mushrooms lower risk of prostate cancer?

If you go down to the woods today you're sure of a big surprise.  Mushrooms.

A new study published in the International Journal of Cancer has found an inverse relationship between mushroom consumption and the development of prostate cancer among middle-aged and elderly Japanese men, suggesting that regular mushroom intake might help to prevent prostate cancer.

A total of 36,499 men, aged 40 to 79 years who participated in the Miyagi Cohort Study in 1990 and in the Ohsaki Cohort Study in 1994 were followed for a median of 13.2 years. During follow-up, 3.3% of participants developed prostate cancer.

Compared with mushroom consumption of less than once per week, consumption once or twice a week was associated with an 8% lower risk of prostate cancer and consumption three or more times per week was associated with a 17% lower risk.

So what to look out for? Is there any particular type of mushroom that produces a better outcome?

“Since information on mushroom species was not collected, it is difficult to know
which specific mushroom(s) contributed to our findings. Also, the mechanism of the beneficial effects of mushrooms on prostate cancer remains uncertain,” says lead author Shu Zhang, PhD, of the Tohoku University School of Public Health, in Japan.

The lion and the wildebeest

Birds flock, fish school, bees swarm, but social being is more than simply sticking together.  Social groups enable specialisation and a sharing of abilities, and enhances ability, learning and creating new tricks. The more a group works together, the more effective they become as a team.  Chimpanzees learn from each other how to use stones to crack nuts, or sticks to get termites.  All around us we see cooperation and learning in nature.  Nature is inherently creative.  Pulling together becomes a rallying cry during a crisis.  We have heard it throughout the coronavirus pandemic.  "We are all in this together", a mantra that encourages people to adopt a common strategy. In an era of 'self-interest' and 'survival of the fittest,'  and 'selfish gene', we lose sight of the obvious conclusion from the evidence all around us.   Sticking together is more often the better approach.  This is valid for the lion as it is also for the wildebeest.   We don't

Noise pollution puts nature at risk

 "I just want a bit of peace and quiet!" Let's get away from all the hustle and bustle; the sound of endless traffic on the roads, of the trains on the railway, and the planes in the sky; the incessant drone; the noise. We live in a world of man-made noise; screeching, bellowing, on-and-on in an unmelodious cacophony.  This constant background noise has now become a significant health hazard.   With average background levels of 60 decibels, those who live in cities are often exposed to noise over 85 decibels, enough to cause significant hearing loss over time.  It causes stress, high blood pressure, headache and loss of sleep and poor health and well-being.   In nature, noise has content and significance.  From the roar of the lion, the laughing of a hyena,  communication is essential for life; as the warning of danger, for bonding as a group or a pair, finding a mate, or for establishing a position in a hierarchy - chattering works.  Staying in touch is vital to working

Therapeutic animal stress

Interacting with animals is known to be therapeutic,  particularly in reducing stress.  But do we consider sufficiently the effects this may have on the animals involved?   We might assume that because it is calming for us, then it must be so for the therapeutic animals, but is this so?  New research suggests that it isn't always without stress for the animals involved.  Positive human-animal interaction relates to changes in physiological variables both in humans and other animals, including a reduction of subjective psychological stress (fear, anxiety) and an increase of oxytocin levels in the brain.  It also reduces the 'stress' hormone, cortisol. Indeed, these biological responses have measurable clinical benefits.  Oxytocin has long been implicated in maternal bonding, sexual behaviour and social affiliation behaviours and in promoting a sense of well-being .  So far, so good.  We humans often turn to animals for stress relief, companionship, and even therapy.  We kno
