A study published in Oct of this year (in the journal Advances in Nutrition) aimed to evaluate the benefits of antioxidants on sperm count and quality1. There have been numerous studies in this field but, as often in science, it can be hard to pin down a definitive answer. This is a well-designed meta-analysis which tries to take into account data from lots of different studies and apply rigid statistical analysis to make sure that the effects seen are true (or to be as sure as we can be). This meta-analysis amalgamated data from 18 separate studies including almost 1800 men.

But with the average person gaining an extra 3 – 7 pounds over Christmas, that is not going to make January feel any less dismal.

The nervous system in our gut has been called the ‘second brain’. It is connected to our brain via sympathetic and parasympathetic pathways and has bi-directional activity. In simple terms, this is the gut-brain axis, and it works both ways. A review published in October 2021 discusses the roles of gut bacteria and intestinal cells in chronic pain, neuropathy and hyperalgesia (increased sensitivity or response to pain)1. It is important to note that many studies which explain pathways and signalling are carried out in mice. This is very common in cell signalling and in nutrition. [Read more…]
Many of us may be able to relate to feeling better when we eat dark chocolate. Several of it’s constituents have known positive effects on mood. These include theobromine and tryptophan, the precursor to our feel good neurotransmitter serotonin. However, new research has shown another way in which dark chocolate enhances mood – by changing our microbiome. This community of bacteria, archae, yeasts and other organisms that reside mainly in our gut profoundly affects our mood and immune system as well as our digestion.
For many years, scientists and healthcare professionals believed the urine to be almost sterile. Now we know much more about the bacteria that live in our body and know that we have a microbiome not only in our gut, but in the mouth, vagina, the placenta and in the urinary tract. [Read more…]
