In the spirit of cooperation, I want to contribute to the author and the steemit community what I've learned about antioxidants.

First, I researched the OTAC scale and it is not an antioxidant measure. This scale was referenced in a source link in the article which lead to a Dr. Axe article. Dr Axe also incorrectly references OTAC without a breakout of the acronym or a link to the scale.
I found this and it isn't what we're looking for...http://www.otac.info/

The scale people should seek out for antioxidant scores is
ORAC (Oxygen Radical Absorption Capacity)...the website for this is: https://www.superfoodly.com/orac-values/

What has been learned from studies of blue zone cultures and longevity (see Dr. Joel Wallach's book, Immortality) is that the minimum daily ORAC for good health is 20,000 ORAC per day. And if one is suffering with severe oxidative damage, then the daily values need to be raised to 100,000 to 200,000.
Most people only consume approximately 1500 ORAC per day. Should we be surprised at the numbers of people suffering from inflammatory disease?

Antioxidants are just one of three essential categories of ingestibles for humans to consume each day in order to support the structure and function of the human body...to repair and maintain optimal nutritional wellness.

I agree with the author about the high ORAC available in cinnamon.
I hope my comments are helpful.
