We’ve all heard the reports that chocolate can be good for you. But it turns out there’s a healthier alternative: cacao! Discover all the chocolatey goodness about cacao, its top 5 nutritional benefits, and how you can incorporate this superfood into your diet.
Cacao: A semi-sweet history
The word cacao comes from the Olmec word kakaw. Cacao consumption can be traced back 4,000 years to the Maya, Toltec, and Aztec civilizations.
The Aztecs not only used cacao beans as currency, but also as a beverage for the wealthy and elite.
Moctezuma II, the famous Aztec ruler and namesake of Moctezuma’s revenge aka traveler’s diarrhea, would drink 50 cups of xocōlātl, which means “bitter water,” every day. (Legend has it he would drink one more before visiting his harem for its stimulating effects.)
Mayans, regardless of social status, would drink cacao during religious and wedding ceremonies.
It wasn’t until the 16th century that Spaniards had the idea to add cane sugar and milk to the chocolate beverage.
Cacao: A delicious & nutritional chocolate superfood
Cacao is the purest form of chocolate you can eat. While cacao has a chocolatey taste, it’s pretty bitter. This is because it’s not sweetened or processed like traditional candy bars. Because cacao is not heavily processed, it retains its high antioxidant content.
Raw cacao contains 4 times more antioxidants than regular dark chocolate and even 20 times more than blueberries. What’s more, research the antioxidant content in cacao is even more beneficial to your health than tea.
According to a 2008 study published in the “Journal of Agricultural and Food Chemistry,” 60-90% of the original antioxidants in cacao are lost through “Dutch processing.” So if you want to reap all the benefits from chocolate, stick to cacao.
In addition to being rich in antioxidants, flavonoids and phytochemicals, cacao is high in non-heme (plant-based) iron as well as zinc, potassium and magnesium.
5 Nutritional Benefits of Cacao
1. Cacao can improve your mood
Does eating chocolate make you happy? Because, same. However, there’s actually a science-backed reason why.
Cacao stimulates the brain to release neurotransmitters, which can trigger emotions like euphoria. When you eat cacao, the body produces a natural, adrenal-related chemical called phenylethylamine (PEA). It usually occurs when you feel excited or in love, causing your pulse to speed up. PEA also allows for more focus and awareness.
Cacao also contains anandamide, which is sanskrit for divine joy. Also known as the “bliss molecule,” it binds to cannabinoid receptors and mimics the effects of THC — the psychoactive molecule in cannabis. In addition to improving your mood, research shows anandamide can inhibit the growth of breast cancer cells.
2. Cacao can prevent heart disease
Do you love chocolate? It will love you back — or at least your heart.
Multiple observational studies support that dark chocolate (which contains less sugar and no dairy products) can prevent heart disease:
- A 2006 study that followed 470 men over a 15 year period found that cocoa reduced the risk of death from heart disease by 50%.
- The National Heart, Lung, and Blood Institute Family Heart Study found eating dark chocolate at least times per week lowered the risk of heart disease by 57%.
- A 2011 study published in “The American Journal of Clinical Nutrition” saw a 32% reduction of calcified plaque in the arteries when chocolate was consumed two or more times per week.
One of the many ways chocolate can protect the heart is by inhibiting the oxidation of LDL cholesterol (aka the “bad” cholesterol). When LDL oxidizes, it sticks to the walls of arteries, which increases the risk of stroke or heart attack.
The polyphenols (the protective chemicals found in plant foods) have an aspirin-like effect and prevents the clumping of blood platelets. This a good thing since the clumping of platelets can lead to atherosclerosis or the hardening and narrowing of the arteries due to a buildup of fat and cholesterol.
3. Cacao can lower blood pressure
According to the American Heart Association, high blood pressure is a “silent killer” because there are no obvious symptoms that indicate anything is wrong. In fact, most people don’t even know they have high blood pressure.
High blood pressure can lead to a variety of health problems, such as heart disease, stroke, kidney failure and more.
So how can chocolate help prevent high blood pressure? The flavonols in dark chocolate can stimulate the lining of the arteries, known as the endothelium, to produce nitric oxide. Nitric oxide signals the arteries to relax, which promotes normal blood pressure.
Research also shows that consuming a small amount of dark chocolate every day can lower blood pressure in those with mild hypertension.
While chocolate may help lower your risk of high blood pressure, following a heart healthy diet (especially rich in plants!) can have a greater impact.
4. Cacao is good for your brain
Have chocolate on the brain? That may not be such a bad thing. Chocolate is often listed as one of the top foods for brain health — and there’s plenty of research to back that up.
The flavanols in dark chocolate have been shown to relax the arteries and increase the flow of oxygen to the brain.
A 2012 study published in “Hypertension” showed that the regular consumption of cocoa flavanols might be effective in improving cognitive function in elderly people with mild cognitive impairment.
In addition to its brain-boosting benefits, a 2017 meta-analysis also found consuming up to 3 servings of chocolate a week can lower the risk of stroke.
5. Cacao can have anti-diabetic effects
For those who have type 2 diabetes, consuming dark chocolate may be beneficial.
Researchers at the Institute of Food Science and Technology and Nutrition found cocoa flavanols can slow down carbohydrate digestion and absorption in the gut, improve insulin secretion, reduce inflammation and stimulate the uptake of sugar out of the blood into the muscle. However, they do warn against consuming chocolate that is high in sugar.
The same 2012 study in “Hypertension” that showed positive effects of chocolate on the brain, also found cocoa flavanols reduced insulin resistance.
