We have all been there: deadlines are looming, your anxiety is spiking, and suddenly you find yourself desperately reaching for a piece of chocolate. Before you feel guilty or blame a lack of willpower, you should know that this craving is deeply rooted in your biology.
When you are stressed or anxious, your brain is actively seeking chemical and emotional relief, and chocolate is uniquely equipped to provide it. Here is a look at the science behind why we turn to chocolate in times of stress, and how you can indulge this craving in a brain-healthy way.
1. The Serotonin Surge
When you are under chronic stress or anxiety, your brain’s “feel-good” chemicals can become depleted. Dark chocolate acts as a natural remedy because it actively increases serotonin in the brain. Serotonin is a critical neurotransmitter that regulates your mood, improves your sleep, and controls your pain and cravings. By reaching for chocolate, you are instinctively giving your brain the building blocks it needs to self-soothe and stabilize your mood.
2. Brain-Protecting Flavonoids
When your body is stressed, it generates inflammatory free radicals that can damage your cells. Fortunately, raw cacao is incredibly rich in flavonoids. These powerful plant-based antioxidants have been shown to directly protect your neurons from damage while simultaneously supporting a brighter mood.
3. A Boost in Blood Flow
Chronic stress and high cortisol levels can restrict your blood vessels. Cocoa is packed with flavanols, which are known to improve your cardiovascular system’s ability to pump blood throughout the body and brain. This increased blood flow delivers vital oxygen and nutrients to your brain, helping to clear out the mental fog that often accompanies high anxiety.
4. Deep Emotional Comfort
Beyond the biochemistry, eating something sweet simply provides genuine emotional comfort. Having a sweet treat can satisfy your emotional side and help comfort you when you are going through hard times in your life, such as a child being sick, dealing with a highly demanding boss, or navigating the intense hormonal shifts of menopause.
How to Stress-Eat Chocolate the Right Way
While your brain benefits from chocolate, it does not benefit from the massive amounts of refined sugar found in standard commercial candy bars. As we know, heavy sugar crashes lower blood flow to your brain dramatically and worsen anxiety. To get the stress-relieving benefits without the crash, here’s what I recommend:
- Stick to Dark Chocolate: Aim for about one ounce of sugar-free, dairy-free dark chocolate every day, or ensure your chocolate is at least 70% cocoa or higher. In fact, Dr Daniel Amen and his clinics recommend eating an ounce of dark chocolate as a daily intervention for dealing with too much stress.
- Pair it with Healthy Fats: Combine your chocolate with nuts or seeds. You can easily make Walnut-Cacao Energy Squares by blending raw cacao powder, walnuts, chia seeds, and dates. The omega-3s in the walnuts and chia seeds will further support your mood and protect your brain.
- Try Stuffed Dates: For a quick, comforting snack, take a Medjool date, stuff it with sunflower seed butter, and dip it in 70% dark chocolate. The sunflower seeds add a dose of vitamin E to calm brain inflammation, giving you the perfect, guilt-free sweet treat to combat your stress.
