I am including as a super food, any food that has been shown to cure something. It is not enough that a food is good for us. It must also be reputed to cure something, even if mainstream medical research has not confirmed this.
There is anecdotal evidence reported every day that some food has cured some disease. There was the person who cured Hep C with canned beetroot, or the person who cured cancer with asparagus. The world is full of these stories.
We can’t know for sure if the stories are true, but we do know that the foods they cite are almost always very high in anti-oxidants. Anti-oxidants are very good for us, whether we are healthy or sick, so the stories could be true.
If we eat a range of foods that are extremely high in anti-oxidants, they should protect us from just about every disease and perhaps even cure a few.
