Chocolate lovers often find themselves torn between taste and health. With shelves full of options—from dark and milk chocolate to nut-filled and white varieties—many people assume chocolate is unhealthy and avoid it altogether. However, not all chocolates are bad for your health. The key lies in choosing the right kind.
A video by Harvard-based doctor and health educator Dr. Saurabh Sethi has recently gone viral on social media, where he explains which chocolates are healthier and which ones should be avoided. In the video, Dr. Sethi reviews seven types of chocolate, rating each based on its nutritional value and health benefits.
Let’s take a closer look at which chocolates made the cut—and which didn’t.
Dark Chocolate Tops the List
According to Dr. Sethi, dark chocolate is one of the healthiest choices available. It is rich in flavonoids, low in sugar, and supports heart and brain health. He rated dark chocolate 9 out of 10, making it an excellent option for regular consumption in moderation.
Milk Chocolate: Tasty but Sugary
Milk chocolate contains more sugar and fewer antioxidants. Dr. Sethi suggests that while it can be enjoyed occasionally, it should not be eaten daily due to its high sugar content.
Milk Chocolate with Nuts: Not as Healthy as It Sounds
Many believe that adding nuts makes milk chocolate healthier. However, Dr. Sethi clarifies that despite the nuts, milk chocolate remains high in sugar and should still be limited.
White Chocolate Falls Short
Dr. Sethi is particularly critical of white chocolate, stating that it contains only cocoa butter and sugar, with no antioxidants. “I don’t even understand why people call it chocolate,” he remarks.
White Chocolate with Nuts: Still Unhealthy
Even with added nuts, white chocolate remains a poor choice nutritionally, as it lacks cocoa flavonoids, which are responsible for most of chocolate’s health benefits.
Nut-Coated Dark Chocolate: The Healthiest Option
The top spot goes to nut-covered dark chocolate, which Dr. Sethi rates a perfect 10 out of 10. This variety is rich in protein, fiber, healthy fats, and polyphenols, making it the best choice for both taste and health.
Ultra-Processed Chocolate: The Worst Choice
At the bottom of the list is ultra-processed chocolate, which contains excessive sugar, refined oils, and artificial additives. Dr. Sethi warns that these chocolates are harmful to gut health and metabolism and should be avoided.
Final Takeaway
If you love chocolate but care about your health, opt for dark chocolate—especially nut-coated varieties—and stay away from highly processed and sugar-loaded options. With the right choice, chocolate can be both delicious and nutritious.
