Protein is important for stamina. But don't be fooled by companies promoting protein bars. Most of these bars have enough sugar in them to rob them and erase most of the benefits of the vitamins, minerals and protein that they so proudly tout. Look at the label. Let's be perfectly clear here.
Sugar is white table sugar, brown sugar, honey, maple syrup, corn syrup, sucrose, and fructose.
There are other names for sugar that you will see on food labels but these are the most common. Yes, but it is a synthetically derived fruit sugar without the natural enzymes and other fine nutrients found in REAL fruit that only mother nature can provide. When you eat fructose or any other of these new names for sugar in a cookie or health bar, be honest with yourself. I gave the Dance Street Performers a little lecture on sugar a few days ago and drew a picture of a little man with all his muscles screaming for vitamins. I showed the man eating sugar instead.
