I am not an expert. I have just tried to help those who are interested in purchasing protein bars for their diet, but not an expert in protein bars. It is important to note that not all proteins are created equal.
The protein content of the protein bars I am reviewing are as follows: Mango (100%) - Very low protein, but has the highest content of leucine and is very tasty Ginger (100%) - Has a medium protein to low fiber content, and contains a high concentration of beta-carotene (a cancer fighting agent) Pecans (100%) - Low protein, but contains high concentrations of polyphenols, making it a great source of vitamin C. Cocoa (100%) - Moderate protein to high protein, with a low glycemic index Peanut Butter (50% fat, 25% fiber, 100% sugar) - Moderate protein, high in fiber and contains significant amounts of omega-3 fatty acids. Chewy Chocolate (100% fat, 50% fiber, 50% sugar) - Has a high protein content, with a high glycemic index. Note that the protein content of the chocolate bars I reviewed above can vary between 50-75% depending on the manufacturer. The nutrition information for protein bars listed on the website of the manufacturer was a little off from the amount that I was purchasing. I have been using a protein bar for over 12 years and have never had any trouble with the protein content.
