Alternative treatments

I have a pretty good education and I am a capable woman but discerning among alternative treatments makes me want to run away. I have friends who swear by Chiropractors, others who love naturopaths, and still others who cannot live without accupunture- just to name the most common ones. I am reaching an age where I really need to face that focusing on my health is a now or never sort of proposal. It is not that I am a disbeliever, but I just cannot evaluate whether they are worth spending money on. Supplimentary vitamins for example are not supported by research that I have read and have been referred to as "expensive pee". My biggest reservation is that I am not yet doing all the things I KNOW are valid and that I should be doing. For example, I still eat some sugars and white grains in my diet. I should lose weight and exercise more. Right now, I am fairly healthy (at least symtomatically) and I cannot get excited about any new treatments when I have not plugged in all the recommended ones.
