dispite the great popularity of acai and my great interest in south america, I would be more supportive of broccoli as the greatest superfood. It prevents cataracts and a wide range of other ilnesses, strongly prevents cancer has ever nutrient you need except vitamin B12 and complete protien which are only found in animals and to top it off it is low calorie. besides, unlike broccoli, acai can't even be bought fresh unless one finds themself in the Amazon. To top it off broccoli is relatively cheap, and very cheap at some times. Acai is expensive, broccoli is cheap and with more health benefits anyway. So when you are thinking of buying a healthy superfood you might want to think about spending a couple dollars on lots of broccoli instead on a tiny bit of acai.
