>>70470623i have add and i grew up in austria eating a very balanced diet and the only thing that helped me during my childhood was lots and lots of sports and reading stuff that interest me. but i definitely agree that dietary issues especially during growing up leads to your brain not developing correctly.
the habits you form (like crashing from a sugary breakfast during school not being able to focus etc) can alter your brain in ways which only therapy, a lots of movement and a balanced whole food rich diet can fix.
now as an adult im on a tiny amount of add medication (dexa) and i am considerably calmer and can think clearer which improved my life considerably. for the record i still lift and eat well aside a cheat meal a week.
