Yes And Yes

I am on this nutrition kick. I guess its because I an attending a fitness class where we discuss what is good and what is not so good to eat. Ideally, all of the nutrition we need can come from the food we eat. Unfortunately, in todays world, it usually doesn't. Even if food was grown in nutrient dense soil without contaminates, much of the nutrition is lost in its journey from the field to our table. If your diet consists of a wide variety of nutrient dense, organic whole foods, with lots of raw produce, locally grown (preferably in your backyard) and your digestive system is working at peak performance, then you have little use for supplements. That's a lot of ifs. Avoid processed foods and do not eat anything with artificial flavors, colors, preservatives, trans fats or GMO's. A full 80% of your diet should consist of fresh, raw, organic produce, more veggies than fruit. If this is not possible, then I suggest vitamins and probiotics to supplement your diet.
