Beware of junk food!!

Beware of eating junk - the food that you eat affects your brain. Over a million students in New York were studied. When preservatives, artificial colourings and other additives were removed from the cafeteria menu, 70,000 students performed TWO OR MORE grade levels higher than before - so if you want to be sharp, eat natural, unprocessed foods and wave bye bye to the chips and curry sauce.
