Welcome to the Dr. Berg's Healthy Keto and Interminute Fasting podcast, where Dr. Berg takes you on the journey for the truth about getting healthy and losing healthy weights.

Well, hello. Today we're going to talk about vitamin D in relationship to your immune system.

Now, I had this idea that I already had this video and I searched and I couldn't find it.

There may be a video out that I just can't find that I already did, but I'm just going to do a video specifically on the immune system. First thing you need to know is that vitamin D is intimately

connected to every single immune reaction. In fact, the white blood cells have the ability to make

vitamin D active. So vitamin

is very important. In fact, viruses, as one of their strategies, is to downgrade or turn

off the vitamin D receptor. So you can't get any more vitamin D because apparently they know

that vitamin D is very,

very important. And so that's one way that they thrive. So vitamin D deficiencies occur when there's

not enough sun right in the winter. Why do you think we have the spike of flu and other viral infections. It's because the vitamin D is low. In fact,

in the pandemic of 1918, the Spanish flu, it peaked in January, which is in the winter.

Now, another thing that's interesting about the winter months,

or basically between November and March, we have much higher incidence of autoimmune diseases like lupus, MS, type 1 diabetes, rheumato arthritis, irritable bowel disease. Why? Because vitamin D

is a natural, kind of a steroid, anti-inflammatory, and so it has a

key function in reducing inflammation. When you have an autoimmune disease, the thing that

really creates the damage is the inflammatory process. So if you have enough D, you can have a lot less inflammation.

It's the inflammation that causes all the collateral damage. And what's wild about this is our

own body is creating the damage. And so that's just, it's just really bizarre.

Vitamin D is a immunomodulator. What does that mean

modulator? It means that it helps to normalize something that is too much or too little.

So it brings into a normal range. And specifically, when we talk about like the cytokine storm, where you have this hyper-inflammatory
