Dark Chocolate for Depression
Recent findings may relieve some of the guilt that accompanies the consumption of chocolate, particularly during depressive episodes.
RESEARCH UPDATE
Dark chocolate lowers the risk of depression, according to a
The same effects were not seen with milk chocolate, suggesting that the benefits were not simply due to the pleasures of the food. Indeed, most people rate milk chocolate as the more pleasurable of the two. There is also the possibility that people who strive for a healthy lifestyle are more likely to consume dark chocolate. This treat, after all, has well-publicized health
It did not take much dark chocolate to achieve these antidepressant effects. On average, the consumers of dark chocolate ate only 12 grams a day, a little less than half an ounce. The cut-off for “dark” chocolate was ≥ 45% cocoa. In contrast, the optimal dose for physical health is 1 to 2 ounces a day of ≥ 70% cocoa. Keeping the percentage high and the ounces low maximizes the healthy ingredients while minimizing the calories and sugar.
Chocolate has long been associated with depression. Almost half (45%) of patients in a depressed episodes report craving for chocolate, and many believe that it relieves feelings of
There are several mechanisms that may explain the putative antidepressant effects of dark chocolate.1,4
1. Flavanols. These brain-protecting nutrients are particularly prominent in dark chocolate. They are also found in red wine, berries, apples, citrus, and green and black teas, all foods that are associated with improvements in mood and cognition.
2. Caffeine and theobromine. These adenosine-agonists have rapid effects on energy and cognition. Cocoa is the main source of theobromine, while caffeine is found in many foods.
3. N-acylethanolamines. This fatty acid is an analogue of anandamide, an endogenous cannabinoid with anxiolytic and euphoric effects.
4. Phenylethylamine. A natural monoamine that increases the release of norepinephrine, dopamine, and acetylcholine.
Studies in healthy volunteers attest to the
Though intriguing, these results are not definitive enough to foster sweeping recommendations of dark chocolate for depression. Dark chocolate is not without risks. It has been known to cause migraines, insomnia, kidney stones, and dental problems.
What this study does do is relieve some of the guilt that accompanies the consumption of chocolate, particularly during depression. Even in the studies of healthy subjects, where chocolate enhanced mood, guilt was sometimes noted as an adverse effect.4 Chocolate is one of life’s pleasures, and pleasant feelings help pave the way out of depression. They give rise to altruism, creative problem solving, and social engagement.5[
Clinicians, take note
Patients with depression are not the only ones who can benefit from those mental shifts. The cognitive benefits of chocolate apply to doctors as well.
In the 1990s a series of studies tested whether the positive mental state induced by chocolate could improve medical problem-solving skills.5[
