Maybe we shouldn't be surprised that light and microbes are good for us. They are two of the most influential evolutionary influences on human biology

If, like me, you are interested in how gut microbiota affect human health, read on. Long under-investigated and poorly understood gut fungi appear to affect health much more than their small numbers suggest and likely influence what happens to the much more numerous bacteria each of us have in our gut.

Did you know that an editorial recently published in the British Medical Journal has called for the UN to think about ultra-processed food in the same was as it does tobacco? This follows a review of how ultra-processed food affected the health of almost 10 million people.

This paper describes a pathway through which a well-known toxic metabolite from seed oils may have caused my heart disease. We’re still only just beginning to understand how industrially processed ingredients in our food may cause malnutrition.

Our gut microbiome is continually in contact with our environment and the consequences can be significant. We can easily create and expose our microbiome to a healthy natural environment. This gives us the best chance of maintaining gut health. Attempts to return a damaged gut microbiome to a healthy state are not always positive. Intrusive interventions should be undertaken with great care.

The main ingredient in seed oils is called linoleic acid. It is harmful to our body because it damages our immune system. Its effects on our liver are so dramatic that linoleic can act alone to cause liver disease progression all the way to liver cancer.

I’m in the second half of a century well lived and suffer from age-related muscle loss. This is natural and easily managed by eating enough bioavailable protein and exercising properly. I recently read a great paper about how to get enough bioavailable protein to retain and build back muscles and strength. I describe it here.

Are you interested in finding out more about human nutrition but don’t have the time or patience to search the academic literature? I am interested and find that when I translate that literature into simpler language, it helps me to understand and retain what is being said. This is the first in what may be a series of simple summaries of articles that interest me.
