In recent years at least two studies demonstrated the benefits of flavonoid-rich dark chocolate over milk chocolate as to improved vision. That was good news for chocolate lovers.
In a new double-blind randomized clinical trial (Department of Ophthalmology Ludwig-Maximilians-University, Munich, Germany), the short-term benefits of dark chocolate were once again put to the test.
Unfortunately, this time they saw no benefit to visual function of either dark or milk chocolate. Researchers admit sample size was small (22 participants) and further trials would be needed to rule in or out possible longterm benefits.
Conclusion: Chocolate tastes good!
