There are lots of things we want to do in life.

Climb a mountain, write a song, watch our grandchildren go up.

But guess what? We can't do any of those things if we don't have our health.

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

And I am here to bring you evidence-based research that takes the mystery out of the best way to live a healthier, longer life.

Today on the show we continue our series on potential super foods.

Today's show is looking at the Asahi Berry.

Whenever a new so-called superfood hits the market, the first thing researchers tend to look at is its chemistry and antioxidant capacity.

Based on one measure of antioxidants, the Asahi Berry had the highest of any food reported to date in a report from 2006.

In our first story, we look at the antioxidant content of 300 foods by serving.

The average antioxidant content of much of what Americans eat, peas and carrots, corn, lettuce, bananas, just as a reference.

Let's go in reverse order for the top dozen superfoods starting with number 12, a tablespoon of cocoa powder, which I talked about in my 2007 review.

Number 11, a half cup of blueberries. Blueberries didn't even make the top 10 this year.

In 10th place, a pomegranate, 9th, 1 black plum, 8th, a handful of pecans, 7th, 1 pear, 6th,

I have a cup of cranberries, 5th, and apple, 4th, a teaspoon of cinnamon, 3rd, and an orange joke.

And the runner up, a half cup of goji berries.

And if you're given a choice to eat a single serving of any food on the planet, in terms of antioxidant power,

wouldn't be going to the Himalayas for gojis, you'd go to Brazil.

Way off the charts, nearly 75,000 antioxidant units, a half cup serving of aside berries.

They're so purple, they're black. In fact, the color is so intense that they sometimes actually give

these berries to people before abdominal MRIs, because it actually stains the inside of your

intestine and can kind of act as contrast. Okay, a few observations on our dozen. First,
