What we eat/drink does have an effect on our brains. The American Journal of Clinical Nutrition has suggested that wise food and beverage choices can fuel our brains to work better, sharpen our memory, improve our concentration and may help to prevent dementia and Alzheimer's disease. And it doesn't take complicated or expenses items to do so. One of the simple things recommended by Nutritionist Amanda Albers is to follow the simple 8x8 rule. That is to drink eight 8-ounce glasses of water a day. This one simple thing is an easy way to improve our health and our minds.
