The average American consumes roughly 12 pounds of chocolate each year, and over $75 billion is spent annually worldwide on chocolate. With this much chocolate eating going on, it’s essential to make smarter choices about what kinds you consume so you can enjoy your favorite treats guiltless and take advantage of all the health benefits of dark chocolate.
Although some types are brimming with important antioxidants and polyphenols, it’s important to note that not all chocolate is created equal. The potential perks of processed, highly sweetened chocolate are slim to none, but those of a high-quality dark chocolate are numerous and quite impressive.
So is eating chocolate healthy? Here’s what you need to know about this sweet treat and how you can enjoy it as part of a healthy diet.
Benefits of Dark Chocolate
1. Protection from Disease-Causing Free Radicals
One of the greatest advantages of eating chocolate is its ability to fight free radicals, which are harmful compounds created by cellular processes in the body that can contribute to inflammation and chronic disease.
Antioxidants are the compounds that are believed to neutralize free radicals and protect the body from damage and disease.
Dark chocolate is loaded with antioxidants, including flavonoids and polyphenols. The cocoa, in particular, has actually been shown to have a high count of polyphenols and flavonoids that is even greater than wine and tea.
Therefore, the higher the cacao/cocoa percentage of your next treat, the more awesome antioxidants you’ll eat.
2. Potential Cancer Prevention
It may be hard to believe, but that tasty chocolate you eat and love may also help you ward off cancer. That’s right — one of the benefits of dark chocolate is its potential as a cancer-fighting food.
Research shows that the flavonoids and antioxidants found in chocolate may be especially beneficial against colon cancer. For instance, one animal model found dark chocolate was able to effectively reduce the growth and spread of colon cancer cells in rats.
Another review noted that it could potentially help protect against colorectal cancer due to its ability to decrease oxidative stress, reduce inflammation and block the growth of cancer cells.
3. Improved Heart Health
Flavanols are the main type of flavonoid found in chocolate. According to Cleveland Clinic, research has shown that flavanols have a very positive effect on heart health by reducing blood pressure and improving blood flow to the heart as well as the brain, thereby reducing the overall risk of heart disease.
These flavanols can also help prevent blood platelets from clotting, which could reduce the risk of stroke.
A study published in International Journal of Cardiology had subjects consume either a daily dose of flavonoid-rich dark chocolate or non-flavonoid white chocolate for two weeks. The results showed that flavonoid chocolate intake significantly improved circulation in adults whereas the white chocolate had no positive impact on health.
Another study published in 2015 followed the health of over 20,000 people for 11 years and concluded that higher chocolate intake was associated with a lower risk of heart disease. In fact, among subjects who consumed the most chocolate, 12 percent developed or died of cardiovascular disease during the study compared to 17.4 percent of those who didn’t eat chocolate.
4. Good for Overall Cholesterol Profile
The cocoa butter found in chocolate is high in healthy fats and polyphenols, which are beneficial compounds that act as antioxidants in the body.
A 2009 study published in Southern Medical Journal looked at the impact of chocolate on 28 healthy subjects and found that just one week of dark chocolate consumption improved lipid profiles, decreased platelet reactivity and reduced inflammation.
Another review of ten studies showed that consuming flavonol chocolate was effective at reducing levels of total and bad LDL cholesterol, both of which are major risk factors for heart disease.
5. Better Cognitive Function
Some research suggests that flavonol dark chocolate could increase blood flow to the brain, which could potentially aid in the treatment of cognitive conditions like Alzheimer’s disease and Parkinson’s.
Not only that, but a 2009 study published in the Journal of Nutrition noted that consumption of flavonoid-rich foods — such as chocolate, wine and tea — was linked to better brain function and improved cognitive performance.
6. Improves Blood Pressure
Several studies show that because it increases nitric acid in the body, adding chocolate to your diet can reduce blood pressure levels, which could help protect against conditions like heart disease and stroke.
For example, one 2015 study found that consuming 25 grams of dark chocolate was effective at lowering blood pressure in those with type 2 diabetes and hypertension. Not only that, but it was also able to significantly decrease fasting blood sugar levels as well compared to a control group.
7. Antioxidant-Rich Superfood
In a study published in Chemistry Central Journal, the total flavanol and polyphenol levels as well as antioxidant activity of chocolate and cocoa powder were compared to super fruits like acai, cranberry, blueberry and pomegranate.
What did the study show? The researchers found that the flavanol count of cocoa powder (30.1 milligrams per gram) was significantly greater than all of the other super fruit powders.
It was also revealed that the antioxidant capacity of dark chocolate was higher than all of the super fruit juices except pomegranate. Plus, the total polyphenol levels per serving were also highest for chocolate (about 1,000 milligrams per serving), which was significantly higher than all of the fruit juices except pomegranate juice.
8. Potential Vision Booster
Although more research is needed, one June 2018 human clinical trial observed that contrast sensitivity and visual acuity of 30 participants improved after consuming dark versus milk chocolate, meaning that it could potentially help boost vision.
However, more studies are needed to evaluate how its components could impact vision long term.
9. Protects Skin Health
One of the top dark chocolate benefits for skin is attributed to its flavonol status and its ability to protect against sun damage. In fact, a study out of London found that eating flavonol chocolate could help prevent damage caused by ultraviolet light.
Meanwhile, other research indicates that regular consumption of chocolate may also reduce skin roughness, enhance hydration and improve blood flow to the skin.

10. Reduces Stress
A June 2022 study published in Nutritional Neuroscience evaluated the impact of eating dark chocolate for stress among rats. Researchers found that dietary patterns including dark chocolate reversed the harmful impact of chronic isolation stress on brain nerve cells that impact memory processing and learning.
Although more research is needed on the impact of chocolate for stress in humans, this study suggests that it may improve the brain’s ability to deal with chronic stress.

Risks and Side Effects
Despite the many dark chocolate health benefits, there are several side effects to consider as well. In particular, chocolate has been linked to:
- acne
- weight gain
- bloating
- headaches
- gas
- sleep disturbances
- mood changes
- cavities
- constipation
- nervousness
Additionally, many people wonder whether or not it’s a vegan-friendly food. That depends.
Whether you avoid eating dairy for personal or health reasons, it’s important to be extra careful about label reading to ensure that you get 100 percent dark chocolate. Milk is legally permitted to be put into dark chocolate, but since it’s one of the eight major food allergens, U.S. laws do require chocolate makers to list milk as an ingredient.
According to the U.S. Food and Drug Administration, chocolates are one of the most common sources of undeclared milk linked to consumer reactions. In addition, recent testing by the FDA found that you can’t always tell if a chocolate has milk just by reading the ingredient list.
Many manufacturers make their dark chocolate on the same equipment that they use for milk chocolate production, which increases the risk of cross-contamination. If you’re concerned about milk possibly being in your chocolate, it’s best to contact the manufacturer prior to consumption.
Another possible allergen to watch out for in chocolate (even organic brands) is soy lecithin, which is commonly added as an emulsifying agent. Soy lecithin does contain trace amounts of soy proteins, which have been shown to include soy allergens.
However, soy lecithin does not appear to contain sufficient soy protein residues to induce allergic reactions in the majority of soy-allergic consumers.
Chocolate is not a low-calorie or low-fat food, so these are some other good reasons not to overdo it. Plus, it does contain sugar, especially when it’s combined with other high-sugar ingredients, like dried cranberries or other fruits.
Simply put, the flavor is so rich that you can enjoy it and get the benefits of dark chocolate with just a little piece.
If you have pets, make sure they don’t get into your chocolate stash, since chocolate in all forms is poisonous to both cats and dogs.

How Much to Eat
Although chocolate can be a great addition to a healthy diet, it’s important to keep in mind that each serving packs in a high amount of calories.
To avoid overindulging, it’s best to eat a little piece by itself after a solid meal or include it in a recipe when baking at home. Start with around one ounce per day to keep your calorie consumption under control. Be sure to also make other adjustments to your diet as needed to account for extra calories if you’re enjoying it while on a weight loss diet.
If you have any dietary restrictions, it’s also best to moderate your chocolate intake. While you can enjoy it on a keto diet, for example, it’s best to select varieties with a higher dark chocolate percentage and stick to smaller servings to minimize your carb intake.
Selecting products with at least 70 percent cocoa can also help ensure that you get the best dark chocolate possible.
Additionally, if you’re sensitive to caffeine or looking to avoid caffeine entirely, it’s important to know that there are measurable amounts of caffeine in chocolate. Caffeine overdose side effects can include nervousness, increased urination, sleeplessness and a rapid heartbeat.
For reference, one ounce of chocolate contains around 12 milligrams of caffeine. While this is significantly less than a cup of coffee or an energy drink, it’s still something to be mindful of when picking your portion size if you’re sensitive to caffeine.
