It has been known for more than 40 years that vitamin D is of vital importance in the escalation of defensive immunity at the time of infection. Vitamin D deficiency leads to health issues such as respiratory infections, post-operative infections and recovery from surgery, problems in pregnancy, the development of diabetes, certain cancers and more.
When faced with a pandemic of Covid-19, a virus against which we have no learned immunity, the rapid time-scale brought disadvantages of vitamin D deficiency and impaired immunity into sharp focus. It was soon after the onset of the pandemic that we learned of the high susceptibility of those with low blood levels of vitamin D to critical and fatal Covid-19. It was obvious that a public health imperative to minimise ICU admissions and deaths, would be to correct vitamin D deficiency as soon as possible.
We now have the results of a new study from Israel. It looks at the outcome of Covid-19 related to pre-infection Vitamin D status, and "Guess What?" The outcome is far better in people with the highest (not toxic) blood levels of Vitamin D

Sebastian Rushworth M.D has been thinking about starting a podcast of his own for a while now, where he talks to the most interesting and original thinkers in health and medicine. He listens to a lot of medical and health science podcasts, and there are some that are truly excellent, such as The Drive with Peter Attia, Ivor Cummins' Fat Emperor podcast, and the Diet Doctor podcast with Bret Scher, but they're still far too few to keep him satisfied. There are of course many more, often organized by the big medical journals themselves, which are also ok, but they shy away from interviewing the people with really groundbreaking things to say, because those things often fall outside of the current dominant dogmas. And as we know, the big medical journals are all about maintaining the status quo.
So, since there clearly aren't enough of the types of podcast that he wants to listen to out there, He figured that I have to start one of my own. Well, voila!
In this first episode he talks to Dr. Malcolm Kendrick about his new book "The Clot Thickens". They discuss why the traditional LDL/cholesterol hypothesis of heart disease is wrong, and why the scientific evidence actually supports an alternate hypothesis much more strongly. That alternate hypothesis is the thrombogenic hypothesis, which they go through in some detail. Finally, Malcolm tells us what people should be doing in order to protect themselves from heart disease.

When we are stressed one thing we can’t do to help us stop being stressed is tell ourselves to calm down or worse still someone else telling us to calm down. Fortunately there is a tool we can use to help calm us down in a time of stress and that is the physiological sigh. We do this all the time but we don't know we are doing it, we can do this in a controlled way so we can access the benefits it gives us in stress control. If you think about stress in the natural world something that frightens us will get our heart beating faster so we can run away or fight that thing that threatens us. We don't have control over this.
In our heart there are a group of neurons called the sinoatrial node. These will send information to the brain about the heart so as we take a deep breath our diaphragm will move down and the space the heart has will get bigger. This will slow the blood down in the heart and the brain will tell the heart to beat faster, inhale longer and inhale faster, increasing stress so we can deal with that situation.
So we can do the physiological sigh to calm us down in this situation and here is how it works. When we exhale the diaphragm will move up making the space for the heart a bit smaller and the brain will tell your heart to slow down as the blood will be moving through the heart a bit quicker. Why this tool is so good is because it works in real time when you are stressed and you can calm down right away. .
Here is what to do: breathe once and then twice though your nose without breathing out, then we breathe out in a long flow and repeat. Once then twice in and one long breath out and repeat until you feel the calmer.
