I just ran accross the article by Dr. Dean Ornish where he explains that regular excercise can actually cause the reversal of the aging process, especially when combined with a good diet. He writes:
"You don’t need to read this column to know that exercise is good for you. You probably already know that regular, moderate exercise is one of the best things you can do for your health and well-being. What you may not know is that new research is showing that exercise beneficially affects your genes, helps reverse the aging process at a cellular level, gives you more energy, makes you smarter, and may even help you grow so many new brain cells (a process called neurogenesis) that your brain actually gets bigger.
Really.
So does improving your nutrition. A diet high in sugar and saturated fat diminishes neurogenesis, whereas other foods increase it, including chocolate (in moderate amounts), tea and blackberries, which contain a substance called epicatechin that improves memory. Small amounts of alcohol increase neurogenesis, whereas larger amounts decrease it. Chronic emotional stress decreases neurogenesis, but stress management techniques increase it. Drugs such as nicotine, opiates and cocaine decrease neurogenesis, whereas a study published in the Journal of Clinical Investigation in 1995 showed that cannabinoids (found in marijuana) increase it, at least in rats. (Uh, what were we just talking about?)"
Check it out, then get to the gym!
