Health Benefits of Cocoa: What You Should Know

Cocoa is made from the seeds of the cacao tree and has been used for centuries in foods and beverages around the world.

It is particularly valued for its rich flavour and contains several naturally occurring plant compounds and minerals.

Cocoa is especially known for containing flavanols, a type of plant compound with antioxidant properties. However, the nutritional value of a cocoa product depends on how it is processed and what other ingredients, such as sugar and fat, are added.

When consumed as part of a balanced diet, less processed cocoa products can provide several useful nutrients.

1. Contains antioxidant compounds

Cocoa contains flavanols and other compounds with antioxidant properties. Antioxidants help protect cells from oxidative stress caused by unstable molecules known as free radicals.

Including a variety of plant foods in the diet is generally a good way to obtain antioxidants, and cocoa can contribute to that variety.

2. May support cardiovascular health

Research has investigated cocoa flavanols for their possible effects on blood-vessel function and circulation.

Some studies suggest that cocoa flavanols may have beneficial effects on vascular function and blood pressure in certain people. However, this does not mean that cocoa can prevent or treat heart disease.

For better cardiovascular health, cocoa should be considered alongside established habits such as regular physical activity, a balanced diet, maintaining a healthy weight and avoiding smoking.

3. Provides minerals

Cocoa contains several minerals, including magnesium, iron, copper and manganese.

These nutrients perform important functions in the body. Magnesium, for example, contributes to normal muscle and nerve function, while iron is needed for the production of haemoglobin, which carries oxygen around the body.

The amount of these nutrients can vary depending on the type and quantity of cocoa consumed.

4. May contribute to normal brain function

Cocoa flavanols have been studied for their potential effects on blood flow and brain health. Some research has reported possible benefits for certain aspects of cognitive function, but findings are not strong enough to describe cocoa as a treatment for memory problems or other brain conditions.

Cocoa also naturally contains theobromine and smaller amounts of caffeine, which can have mild stimulating effects.

5. May support mood and wellbeing

Chocolate and cocoa products are often associated with feelings of enjoyment and comfort. Cocoa also contains several plant compounds that researchers have investigated for possible effects on mood.

However, mood is influenced by many factors, including sleep, physical activity, relationships and overall health. Cocoa should not be considered a treatment for depression, anxiety or other mental-health conditions.

6. May support digestive health

Cocoa contains fibre and plant compounds that have attracted interest in gut-health research.

Some research suggests that cocoa compounds may interact with microorganisms in the digestive system. However, more research is needed to fully understand how different cocoa products affect the gut microbiome.

Choosing minimally processed cocoa and consuming it as part of a varied diet can provide fibre and other nutrients.

7. Can be part of a balanced diet

Cocoa can be added to foods such as porridge, smoothies, yoghurt and homemade baked products.

However, it is important to distinguish between unsweetened cocoa powder and highly processed chocolate products.

Some chocolate products contain substantial amounts of added sugar, saturated fat and calories.

Reading nutrition labels and keeping portions moderate can help you enjoy cocoa without consuming excessive amounts of sugar or calories.

Choosing cocoa wisely

When buying cocoa products, consider options with:

• Little or no added sugar
• Minimal processing where practical
• A reasonable portion size
• Ingredients that fit your overall dietary needs

Dark chocolate can contain more cocoa solids than some milk-chocolate products, but it can still contain considerable amounts of sugar and calories.

A final word

Cocoa contains flavanols, minerals and other naturally occurring compounds that make it an interesting addition to a balanced diet.

Research suggests that some of these compounds may support vascular function and other aspects of health, although cocoa is not a medicine and should not be used to treat disease.

For the greatest health benefit, enjoy cocoa in moderation alongside a diet rich in fruits, vegetables, whole grains, legumes, nuts and other nutritious foods.
