I suffer from a chronic thyroid condition, Hashimoto Thyroiditis, and while its not written anywhere in regular medicine manuals, I can keep an active and healthy life if I pay attention to what I eat.
Half an hour exercise a day and healthy food (lots of greens if possible organic) makes a difference to my life like night and day. I like to compare my body to a car. It really matters how you maintain it and unlike cars, you cant buy a new one.
