Scientists used to think that you were born with all the neurons you’d ever have. If you drank alcohol and killed brain cells, well, good luck. Then in 1998 researchers discovered the birth of new neurons in individuals who were near death. Turns out your brain–no matter how old or young–can generate new neurons.
One key to brain growth? Diet. What you eat helps generate healthy neurons with bushels of dendrites (nerve receptors). It also keeps nerve endings firing and allows you to maintain brain flexibility. Even if your memory’s so fried you can’t remember your spouse’s cell phone number, food still provides brain sustenance.
We’ve been in food information overkill ever since scientists discovered that you are what you eat. Contradictory studies analyze every type of food, vitamin, mineral, herb, and combination thereof. Even so, research does reveal old-time wisdom: what you swallow makes you smarter and happier (or slower and more blue).
