Robert Valerde and Brenda Im just apprised me of a list of worst American drinks. I was blown away at the totals of calories and sugar! Even if they were only half-right, these beverages would not be good choices to improve one's brain function. Do you know what you are drinking? My beverages of choice are pure water, herb tea, and delta-E that is produced by IMPaXworld.com (you can obtain more information about delta-E at www.realizations.impaxworld.com).
