The First Rule of Proper Nutrition

"Proper hydration is a critical factor in maintaining and improving your mind as you age."
 Dr. Daniel G. Amen

The brain is 80% water, so proper hydration is key to good health and good cognition.  According to Dr. Amen even slight dehydration increases the body's stress hormones, which decrease one's ability to think clearly.  Over time, increased levels of stress hormones are linked with memory difficulties.  Current recommendations are to drink 8-10 glasses of pure water every day, along with lots of water-rich foods.  This is one, easy way we can support our health.
