It is great to see these reports that are starting to paint a clear picture of the relationship of antioxidants with the reduction, reversal and likely prevention of free radical diseases or oxidative stress. I am a proponent and I hope we will see researchers gather together and start support recommendations for expected free radical levels.
My primary concern presently, is the recommendation for diets high in antioxidant rich foods. It seems research supports that this does little if anything in providing a measurable reduction in free radicals. As food based antioxidants can only fight free radicals on a one to one ratio, it isn't possible to consume enough food to provide the needed antioxidants needed. I have reviewed a study that suggested it would take over 300 oranges, or up to 15 pounds of blueberries daily, to reach a consumption level of free radicals that would be able to measurable reduce free radicals. The reason for this is these are direct antioxidants work at reducing free radicals on a one to one ratio.
There is a herbal product available on the market that is an indirect antioxidant. It is an Nrf2 activator elevating the production of our bodies antioxidants. These antioxidants can control free radicals on a one to one million ratio. This can equate to an average free radical reduction of 40 percent. To my knowledge, there is nothing on the market that can offer this level of protection.
