I appreciate that you cited Harvard Health—it definitely boosts your argument’s credibility. One thing to note, though: the claim that “dark chocolate contains about 70% cocoa” can be misleading since cocoa content varies a lot between brands. Usually, chocolates labeled “dark” have at least 70% cocoa, which is when the health benefits tend to increase. Also, the study you referenced shows a correlation rather than a direct cause-effect relationship, so it’s good to be cautious about making definitive claims. Finally, while dark chocolate generally has less sugar than milk chocolate, some brands still pack a surprising amount of sugar. It might help to include a nutrition label comparison next time to give readers clearer context. Overall, great job—but adding those nuances will make your points even stronger!
