Found this article on ADHD, Diet and Exercise. It's about a miracle cure a young adult had of his ADHD when he improved he diet and got LOTS of exercise. He went off his meds cold turkey and is doing great, so long as he runs 3-6 miles a day.
So, is it a miracle cure? Sure, if you believe there was actually something wrong with him in the first place. From my perspective, his environment and life style were out of sync with his physical needs. When he found the balance that worked for him he didn't suddenly have an ADHD cure. He just found what he needs to be healthy.
What's sick is our modern lifestyle. Refined foods like white sugar and flour are ubiquitous. Natural and whole foods are expensive. Children are confined to small indoor spaces, made to sit quietly at desks for most of their day. Many adults are chained to desk work on a daily basis. Just to get enough exercise to maintain basic health people PAY MONEY for the right to exercise at gyms. What's up with that?!? Most of us don't spend even an hour in natural light in a day. This isn't how we evolved to live.
We evolved to move our bodies regularly, to be in the sunshine daily, and to eat foods whose origins don't have to be guessed at. Books like "The Edison Trait" and "Right Brained Children in a Left Brained World" tell us that what we call ADHD is really just another way to live in the world, a way that has served us well in the past and is still valuable today.
Let's stop calling people dysfunctional if, when you improve their environment, they are not dysfunctional. Let's notice the environmental damage that so injures these folks, and let's appreciate them for being our canaries in the coal mine of modern life.
