Chocolate is often associated with indulgence and guilty pleasures, but did you know that it can also benefit your heart health? Studies have found that consuming chocolate in moderation can have several positive effects on the cardiovascular system.
Dark Chocolate and Heart Health
Dark chocolate, which is chocolate with a higher percentage of cocoa solids, is the type of chocolate that has been found to have the most heart-protective benefits.
This is because the flavonoids in cocoa, which are natural compounds with antioxidant properties, are more concentrated in dark chocolate.
One study found that consuming dark chocolate with at least 50% cocoa solids every day for two weeks lowered blood pressure and improved blood vessel function in healthy adults.
Another study found that eating dark chocolate twice a week was associated with a lower risk of developing calcified plaque in the arteries, which is a risk factor for heart disease.
Lowering Blood Pressure
High blood pressure, or hypertension, is a major risk factor for heart disease. Several studies have found that consuming dark chocolate can help lower blood pressure.
In one study, participants with high blood pressure were given 3.5 ounces of dark chocolate every day for two weeks.
At the end of the study period, their blood pressure was lower and their blood vessels were more relaxed compared to a control group that did not consume chocolate.
Another study found that consuming 1.6 ounces of chocolate every day for eight weeks lowered blood pressure and improved insulin sensitivity in people with high blood pressure and impaired glucose tolerance.
Improving Cholesterol Levels
Cholesterol is a type of fat that can build up in the arteries and increase the risk of heart disease. High levels of “bad” LDL cholesterol are particularly problematic.
Studies have found that consuming dark chocolate can improve cholesterol levels by increasing “good” HDL cholesterol and decreasing “bad” LDL cholesterol.
In one study, daily consumption of 3.5 ounces of dark chocolate for two weeks increased HDL cholesterol levels and decreased LDL cholesterol levels in healthy adults.
Reducing Inflammation
Inflammation is a natural response by the body to injury or infection. However, chronic inflammation can contribute to the development of heart disease.
Research has found that the flavonoids in cocoa can have anti-inflammatory effects. One study found that consuming 1 ounce of dark chocolate every day for two weeks reduced levels of inflammatory markers in the blood.
Protecting Against Oxidative Stress
Oxidative stress occurs when there is an imbalance between free radicals, which are unstable molecules that can damage cells, and antioxidants, which are compounds that neutralize free radicals.
Research has found that the flavonoids in cocoa can act as antioxidants and protect against oxidative stress.
One study found that daily consumption of 3.5 ounces of dark chocolate for two weeks increased antioxidant capacity in the blood and reduced oxidative stress.
Boosting Mood and Cognitive Function
While the cardiovascular benefits of chocolate are well established, chocolate can also have positive effects on mood and cognitive function.
Research has found that consuming chocolate can increase the production of endorphins, which are natural compounds that can improve mood and reduce pain.
Chocolate also contains caffeine and theobromine, which are stimulants that can improve mental alertness and focus.
Conclusion
In conclusion, consuming chocolate in moderation can have several positive effects on heart health.
However, it is important to keep in mind that chocolate is also high in fat and sugar, so it should be consumed in moderation as part of a balanced diet.
