Welcome to the Dr. Berg, Healthy Keto and Intermittent Fasting Podcast.

Now, your host, the man taking your health to a whole new level.

Dr. Eric Berg.

So in this video, I want to talk about how to repair an old, weak, damaged immune system.

When you age, what happens is your immune system starts going downhill.

You have less natural killer cells.

That means you cannot eliminate viruses as well as you did when you're in your 20s.

You're not going to be able to get rid of the tumor cells as efficiently.

Your B cells go down, so that means your antibodies go down.

So your immune system loses the memory, so it doesn't remember past pathogens, so it's not as prepared.

So your immune system is a bit weaker.

Also, you lose your T cells.

And that's like a really, really important part of your immune system with killing off microbes,

preventing autoimmune diseases, decreasing inflammation after an infection,

and also the quantity of parasites won't be there like it was.

So you just have less of these cells eating bacteria and cleaning up stuff.

So you can see that age really creates a huge impact on the immune system.

And so if you also, like myself, had a long history of taking antibiotics as a child or a teenager or adult,

that can greatly weaken your immune system as you get older.

And then if you have chemotherapy, that just kills immune system or steroids.

Now, this was me.

In my 20s, I had really bad poison ivy every single season in the fall.
