Continuing today with more brain information from Dr. Fotuhi, credentials given in previous post, research shows that getting a certain type of DHA can increase the size of your hippocampus in about six months. (The hippocampus is the part of the brain responsible for short-term memory.) This is a type of omega-3 fatty acid found in fish, fish oil and algae. However, according to Dr. Fotuhi, it is almost impossible to get enough from your diet therefore this is an area where supplements are useful. He does state that you should buy supplements that come from algae rather than fish due to impurities such as mercury that might be in the fish oil. Dr. Fotuhi stated, "I really believe DHA is a super brain food. I take 1 gram a day, and so does my wife."
