Dark Chocolate vs. Blueberries: Which Has More Antioxidants?

Antioxidants are compounds found in certain foods that help protect your cells from damage and disease caused by the build-up of unstable molecules called free radicals.

You can boost your antioxidant defenses by eating antioxidant-rich foods, including two of the richest sources: blueberries and dark chocolate.

Dark Chocolate vs. Blueberries: Which Has More Antioxidants?

When it comes to antioxidant content, dark chocolate versus blueberries, neither is necessarily better than the other. They each contribute unique antioxidant properties. Including both, along with other antioxidant-rich foods, in your diet is a great way to ensure your body has a constant supply of antioxidants to utilize.

Antioxidants in Dark Chocolate

The predominant types of antioxidants found in dark chocolate are flavanols and polyphenols.

Flavanols are known to:

• Neutralize free radicals so they can’t cause damage to cells
• Support healthy blood vessel function and blood pressure levels by boosting nitric oxide (which helps them relax and widen to improve circulation)
• Reduce inflammation

Flavanols are also linked to the cardiovascular benefits of dark chocolate.

Polyphenols are known to:

• Protect cells from oxidative damage
• Reduce chronic inflammation
• Support heart and brain health
• Improve gut health by feeding beneficial bacteria

Dark chocolate is extremely rich in polyphenols due to its high cocoa content, especially when you choose ones with a higher cocoa percentage (between 70% and 85%). Dark chocolate labeled as “Dutch-processed” or “alkalized” cocoa contains less flavanol content.

Antioxidants in Blueberries

The primary antioxidants found in blueberries include anthocyanins, vitamin C, and polyphenols. There’s some natural variability in their overall antioxidant content depending on whether blueberries are cultivated or wild, with the latter containing more antioxidants.

Anthocyanins are a type of flavonoid (a subclass of polyphenols) that act as powerful antioxidants and give fruits and vegetables their red, purple, and blue colors. While very high in blueberries, anthocyanins are found in other berries, red cabbage, and dark grapes.

Anthocyanins are known to:

• Neutralize free radicals that damage cells
• Reduce inflammation throughout the body
• Support brain health and memory
• Protect heart health by improving blood vessel function
• Support metabolic health and insulin sensitivity

The reason anthocyanins have special brain-related benefits is that they can cross the blood-brain barrier and have a direct impact on cognition.

Vitamin C also acts like an antioxidant and is known to:

• Directly neutralizes free radicals
• Helps regenerate other antioxidants (like vitamin E) after they’ve been oxidized
• Supports the immune system
• Protects DNA from damage

Unlike polyphenols, vitamin C acts immediately in your bloodstream and tissues.

Like all fruits, blueberries are especially high in vitamin C, whereas dark chocolate contains little to no vitamin C; its antioxidant effects instead come from the other compounds listed above.

How to Eat Them

Here are some tips for incorporating both dark chocolate and blueberries into your diet:

• Add wild or frozen blueberries and shaved dark chocolate to oatmeal
• Use blueberries as a base for smoothies
• Top waffles and pancakes with homemade blueberry compote and/or dark chocolate nibs
• Make a berry, granola, yogurt, and dark chocolate parfait for breakfast or an afternoon snack
• Add dark chocolate nibs to homemade trail mix, which includes nuts, seeds, and dried fruit (try dried blueberries for a unique addition).

Remember, no single food is enough on its own to meet all of your nutritional or antioxidant needs. Enjoy them both as part of a broader, nutrient-dense diet pattern for optimal benefits.
