What if just one lifestyle change could help you avoid getting cancer or diabetes or heart disease or high blood pressure?

This one change could cut your risk of chronic disease and add years to your life.

Well, the simple solution to so many of these problems is to eat a healthy diet.

In other words, one centered around whole plant foods.

Welcome to the Nutrition Facts Podcast. I'm your host, Dr. Michael Greger.

What if you only ate foods that took into account your specific metabolism, your family history, how much you exercise?

Would that be helpful?

Today we start with the question, how useful is personalized nutrition?

Personalized nutrition is rooted in the concept that one size does not fit all and who doesn't want to think they're special?

And others have celiac disease and have to avoid gluten or genetically or lactose intolerant.

There's an enzyme mutation common in some parts of Asia that protects against alcoholism because people with the can't metabolize alcohol is efficient.

So, toxic metabolites build up.

I did a fascinating video about fast versus slow caffeine metabolizers in the difference in health benefits that actually extends to athletic performance.

Caffeine is ergo-genic, performance enhancing, but only in fast metabolizers.

Shaving more than a minute off 10 kilometers of cycling, where slower metabolizers got no benefit or caffeine actually slows them down.

Adding two minutes to their cycling time, depending on which kind of genes they have that codes the enzymes that breaks it down.

But for most people, in most situations, we are more similar than different.
