I was diagnosed with something a few years ago which if I didn't change my diet (no beef, pork, fried foods, no foods with preservatives, low to no salted foods, increase water intake to 3/4 a gallon a day & started eating fresh fruit)that in ten to 20 years id be stuck in bed too tired to do anything/ enjoy life. For me that forced me to eat healthy daily and it has almost healed my affliction upon religiously following such a diet.
