There are basically three macronutrient food categories, protein, carbohydrate and fat. However there are other minor nutrients which do not fit clearly into any of the three groups. These include ethyl alcohol, glycerin, and sugar alcohols.

Ethyl alcohol, contained in alcoholic beverages, cannot be used directly by the body as a source of energy. Instead, the alcohol that is consumed goes to the liver, where it is converted into fat and carbohydrates.

Sugar alcohols, like sorbitol, are chemically alcohols, but they are derived from sugar molecules. They are much slower to be absorbed from the intestine than sugars and are metabolized differently. Therefore, they have little or no effect on insulin production.

Glycerin is a by-product of fat metabolism. It can also be ingested as an ingredient in some foods. Glycerin is metabolized much like carbohydrates, except that there is no corresponding increase in either insulin levels or blood glucose.

Technically ConsumerLabs.com is correct in their analysis, the practical reality is the functional carbohydrate level will actually cause insulin levels to rise. Insulin is the major concern that will cause metabolic havoc with the body.

Glycerin does appear to be a safe "atypical carbohydrate" since it does not cause insulin levels to rise.

To the best of my knowledge -- until now - there's been no healthy energy bars. My team and I have been researching this market for quite a few years. But for the many reasons listed in the above article, I've never been satisfied with even the very best bars on the market. And that's why we decided to make an energy bar of our own.

It hasn't been an easy task. I had to bring in one of the world's top biochemists. It's taken a full year of detailed research ... and of course -- tens of thousands of dollars. Even after we had our basic formula, we had to change it 16 times to improve it to the point where we truly believe it is the healthiest and best-tasting bar on the market.

But we finally did it! The Protein Bar is a nutritional powerhouse loaded with a perfect balance of healthy fats, protein and fiber that will truly nourish your body rather than contribute to disease (like so many of the unhealthy bars on the market today do) ... Plus, it really tastes delicious!

I still believe that whole, unprocessed high-quality food is the optimum choice, but there are many of us who live a life where it is just virtually impossible to consume this type of food daily. With Protein bars on hand, you can rest assured that you are making a truly convenient, delicious and completely healthy choice!
