Simple sugars are carbs with one (monosaccharide) or two (disaccharide) sugar molecules. They literallly are sugars. If you are attempting to assert that all non complex carbohydrates are sugars, you are wrong. A potato or a serving of pasta is not at all like a candy bar. Bros science diets might be bad for your brain, btw.
