This month my wife and I started a new "diet." Although we've both been moderately active and have eaten quite healthily for the last decade, we've both been hit with cancer (me once, my wife twice within a period of 18 months).
Like most people who have been dealt a traumatic health blow, we tried to exert control where we could, and this meant our eating habits and immediate environment. We started reading labels of EVERYTHING—food, lotion, shampoos, medicines... everything. We stopped buying items with unhealthy ingredients—Parabens, preservatives such as BHT & BPA. We greatly lessened our intake of processed sugars and sweeteners. We started eating mostly vegetarian, mostly organic....
And still, we suffer from aging and health issues—bad knees, aching joints, pre-diabetes, failing eyesight, increasingly worse allergies. Basically, we're getting older and feeling it.
