Candy bars are like sodas. You may already be taking in 200 – 300 calories per bar. Each bar also provides at least 20 grams of sugar. It may also contain nuts and chocolate which are both good for you, however, some have less than what is advertised. If you really like chocolate, then, buy the ones that offer 75% dark cacao. 2 – 3 squares of it should be enough to satisfy that sweet tooth while basking on its antioxidants.
