I am certain of one thing and one thing only in this regard. If we eat the food, breathe the air, and drink the water, we will die. I've mainly quit listening to the experts. According to them I should have been dead many years ago but actually have very few health problems. There is no one thing that is good for every single person, we're all different and what works for one doesn't for another. I don't see doctors because they will not listen when I tell them I have odd side effects from prescription drugs and if they do listen then the only solution they've offered is another drug to counteract the side effects. A doctor would prescribe drugs for arthritis; I cut out dairy products and take turmeric and my joints are mostly close to pain free most of the time. To each her/his own, may we all be as healthy as possible!
