This claim is true, as the source provided found in a study that men who ate "dark chocolate released less cortisol". Cortisol is the primary stress hormone found in the body, as I learned from the article. While dark chocolate might be the best, most effective stress reliever, people in another study who ate milk chocolate "lowered the stress they felt by two to three points". This VeryWell study was more focused on men, so I also utilized another source to check this claim in women. The National Library of Medicine found that consumption of different chocolate types is an "effective way to reduce perceived stress in women". Overall, my research concluded that both milk and dark chocolate can help decrease specific hormones such as cortisol, which directly influence stress levels. However, dark chocolate might be more effective in doing so.
