The picture shows a comparison of the nutritional values of a Snickers classic chocolate bar and its protein alternative. It is obvious that protein Snickers contains fewer carbohydrates (and sugars) and less fat (and satturated fatty acids). On the contrary, protein content is five times higher in protein bar than the classic Snickers.
However, energy value of a 50g protein bar is as a hearty snack, such as a slice of toasted bread with ham, cottage cheese and vegetables.
What will fill your stomach more? What gives you more nutrients? – 50g snickers or sandwich with vegetables?
