Well, I guess that all depends on who you ask. Relatively, whole grain bread is healthier and more nutritious than white bread...it provides more nutritious "stuff" for your body to use. Some diet plans discourage grain consumption and some have grains as a part of the plan. So my opinion....it's good for you, but not a part of some diet plans.
"There's no such thing as failure. There's only feedback. Stop judging yourself & start recognizing it for what it is, an entry point for learning. The truth is, if you're not failing then you're not really reaching & really trying. If you don't like the outcome of a situation, learn from it, make corrections & reapproach wiser & stronger until you achieve your goals."
