With chocolate’s growing recognition in the health and wellness community, it’s worth exploring the reasons behind this revered food’s nutritional benefits and distinguish between the different types of chocolate and their unique qualities.
The name for the cacao tree, Theobroma cacao L., comes from the Greek words theos (god) and broma (food), meaning "Food of the Gods." This name reflects the high regard ancient civilizations, such as the Mayans and Aztecs, had for cacao.
Who doesn’t love chocolate? Its appeal is so widespread that global chocolate consumption averages nearly 1 kg per person each year.
How is chocolate made and the different types
The journey from cocoa bean to cocoa powder and chocolate bar involves several steps, starting with the harvesting of the cocoa pods, followed by fermentation, drying, roasting, and grinding of the cocoa beans. This process yields cocoa liquor, from which cocoa mass, cocoa butter, and cocoa powder are extracted. These are key ingredients in the production of chocolate.
While chocolate, as we know it, is processed in these ways, this does not mean it should be classified as an ultra-processed food (UPFs) -which we are all learning are generally bad for our health- as it does not involve chemical synthesis or extraction of substances from whole foods and no unknown additives are used, unlike UPFs.
Dark, milk and white chocolate
Dark chocolate contains a higher percentage of cacao solids and less sugar, while milk chocolate includes milk solids and more sugar, resulting in a creamier texture and sweeter taste. Dark chocolate also has a higher caffeine content than milk chocolate - equivalent to green tea - so do not worry unless you overdose; it is not enough to affect your sleep. White chocolate, although technically not chocolate due to the absence of cacao solids, is made from cocoa butter, sugar, and milk solids.
Dark chocolate, containing at least 70% cacao, stands out for its high concentration of polyphenols, which have been linked to various health benefits such as improved cardiovascular health, reduced inflammation, and enhanced insulin sensitivity. These benefits arise from the antioxidant properties of these compounds in combating oxidative stress, a key contributor to many chronic diseases.
In addition to epicatechin and procyanidins, cocoa and dark chocolate are also rich in other bioactive compounds that contribute to their health benefits. For example, theobromine, a stimulant similar to caffeine, has been shown to improve mood, boost cognitive function, and support heart health. Cocoa is also a good source of magnesium, an essential mineral involved in hundreds of biochemical reactions in the body, from energy production to muscle function and nerve regulation.
Each stage of chocolate production significantly influences the flavor profile and nutritional content of the final product. For example, roasting not only develops the characteristic flavors of chocolate but also affects the stability of these essential compounds associated with cocoa health benefits. While the total amount of polyphenols may decrease, some studies suggest that certain polyphenols may become more accessible to the body after roasting, even if their overall concentration decreases. Fermentation is equally critical, enhancing the development of flavor compounds and increasing the bioavailability of antioxidants. Milk chocolate, having a lower percentage of cacao solids, does not contain the same health-promoting properties as darker chocolate.
How to choose your chocolate?
It follows from the above that not every type of chocolate is the same, and every chocolate bar will have a different nutritional profile according to where it is sourced and how it is processed. When choosing chocolate, a good starting point is to check the ingredient list. Ideally, cocoa should be listed first. Be cautious of dark chocolate that doesn’t specify a cocoa percentage, as it may contain only 50-60% cocoa. Avoid products with added butter, vegetable oils, artificial sweeteners, or milk substitutes. The fewer ingredients, the better! It's also wise to limit milk chocolate (10-50% cocoa) and white chocolate (which contains no cocoa and therefore no flavanols), as they tend to be high in sugar.
It’s also important to be aware of the environmental and social impacts of cocoa farming. The cacao industry is linked to deforestation, climate change, and poor labor practices, including child labor. To make more ethical choices, look for chocolate that is organic or fair-trade certified, as this supports sustainable farming and fair wages. Choosing smaller, ethical producers can also help promote transparency and more responsible practices within the industry.
In conclusion, how much chocolate should you eat?
Research suggests that consuming around 25 to 50 grams of dark chocolate per day can provide health benefits. However, it's important to note that while moderate consumption of dark chocolate can be beneficial, chocolate is a relatively energy-dense food. Consuming high amounts of it regularly can also contribute to weight gain, increase sugar intake, disrupt blood lipid levels, and potentially negate the health benefits associated with its bioactive compounds. The key is to integrate dark chocolate into a balanced diet, ensuring that it complements other nutrient-dense foods rather than serving as a primary source of antioxidants. Milk chocolate should be an occasional treat, and as always, moderation is key!
