Chocolate is more than just a delightful treat; it represents cravings, celebrations, and the warmth of comfort.
Its rich flavor, creamy texture, and indulgent experience make it no surprise that its scientific name translates to ‘food of the gods’ in Greek, according to Jen Messer, a registered dietitian and president of the New Hampshire Academy of Nutrition and Dietetics.
Our love for chocolate intensifies during specific occasions, particularly when it symbolizes romance and affection. For instance, around Valentine’s Day, a staggering 58 million pounds of chocolate are purchased each year.
However, chocolate’s allure extends beyond its delightful taste and traditions. Its true power lies in its effects on the brain and body, creating sensations of pleasure, comfort, and connection that can have both positive and negative implications.
What is Chocolate? How is it Made?
The creation of chocolate starts with cacao beans, the seeds harvested from the cacao tree, which thrives in tropical climates near the equator. Once cacao pods are picked, the beans undergo fermentation and drying, a vital process that enhances chocolate’s intricate flavor profile.
According to Messer, “The beans are ground into a thick paste known as cocoa liquor, which contains both cocoa solids and cocoa butter.”
From this point, “various types of chocolate are produced by adjusting the ratios of cocoa solids, cocoa butter, sugar, and milk,” explains Lisa Young, a registered dietitian nutritionist, author of “Finally Full, Finally Slim,” and an adjunct professor at New York University.
Dark chocolate boasts “the highest concentration of cocoa solids, resulting in a larger amount of beneficial polyphenols and bioactive compounds,” says Messer. It’s also lower in sugar and contains no milk.
Milk chocolate, on the other hand, incorporates added milk or milk powder, typically containing less cocoa and more sugar, resulting in a creamier texture and sweeter taste, according to Young.
White chocolate contains cocoa butter but lacks cocoa solids, which means it misses out on many of the classic chocolate favors and the beneficial antioxidants found in dark chocolate, points out Messer.
Why Does Chocolate Make You Feel Good?
Chocolate’s reputation for boosting mood is supported by biological evidence. “Several mechanisms explain how chocolate can elevate both mood and enhance mood,” Messer explains. One such mechanism involves “compounds like epicatechin found in dark chocolate, which promote nitric oxide production, enhancing blood flow to the brain,” she adds.
Additionally, chocolate activates the brain’s reward pathways. Cocoa contains compounds that boost serotonin and dopamine levels — neurotransmitters linked to happiness, motivation, and satisfaction. This helps clarify why chocolate is so gratifying and why cravings for it can be compelling.
Another factor contributing to the feel-good effects is the presence of methylxanthines like theobromine and small quantities of caffeine. “These compounds can enhance alertness, alleviate fatigue, and further uplift mood,” says Young.
Moreover, chocolate contains phenylethylamine, sometimes referred to as the “love chemical,” due to its association with “feelings of attraction and excitement,” according to Young. Yet, this idea is debated as phenylethylamine is broken down during digestion, leaving little impact on the brain.
Is Chocolate Also Good for Your Health?
Besides its mood-enhancing qualities, chocolate — especially dark chocolate — has been associated with various health benefits, “including long-term cognitive advantages,” notes Messer.
One notable advantage is that “the flavanols in cocoa may bolster neurogenesis (the development of new brain cells) in the hippocampus, the brain area responsible for memory and learning,” she adds.
Rich in flavanols, dark chocolate possesses antioxidants that aid in reducing inflammation and promoting heart health, according to Young. Studies suggest regular consumption of flavanol-rich dark chocolate may lead to modest improvements in blood pressure and cholesterol levels. Furthermore, dark chocolate’s antioxidant properties can alleviate oxidative stress, which may help in mitigating aging effects and chronic diseases.
“However, these benefits primarily apply to dark chocolate, not white or sugary milk chocolate,” cautions Messer.
Nevertheless, regardless of the type you prefer, chocolate remains calorie-dense and often contains high levels of saturated fats and added sugars, particularly in milk chocolate and chocolate confections. In fact, “some chocolates can contain up to 50% sugar,” warns Messer, highlighting the need for moderation. Excessive sugar consumption is linked to increased risks of heart disease, type 2 diabetes, and weight gain, according to Young.
For those prone to migraines, overindulging in chocolate can be problematic due to naturally occurring compounds that may trigger sensitivities. Additionally, people with GERD may find that chocolate exacerbates their symptoms, adds Messer.
Ultimately, chocolate can be integrated into a balanced diet when chosen wisely. “Especially if we opt for dark chocolate and savor it mindfully,” suggests Messer. “Just ensure that portions remain reasonable so that the added sugars and calories do not overshadow the health benefits.”
