Research indicates that dark chocolate containing 50 to 70% cacao can alleviate stress, improve gut health, and enhance blood flow, indirectly strengthening the immune system.
The flavonoids or polyphenols found in dark chocolate have been linked to disease prevention, including cancer and heart disease. Cocoa powder is a rich source of polyphenols, antioxidants, potassium, magnesium, fiber, and arginine.
Flavonoids have anti-inflammatory and antioxidant properties that can help improve immune function. Dark chocolate can also increase blood flow and assist with immunity by protecting cells while the immune system fights infections and diseases.
Studies have shown that dark chocolate with a higher cacao concentration has a more positive effect on immunity, mood, memory, and cognition.
Additionally, fiber found in chocolate supports a healthy gut, which can also have a positive effect on immunity.
While there is no direct evidence that dark chocolate can protect against specific illnesses, it may indirectly support immune function.
