It sounds like a simple question: What is the difference between a teaspoon of cocoa and a teaspoon of instant coffee? Both are dark powders, both come from natural beans, and both make up our morning or afternoon ritual. But once you dive in, you discover a whole world of active compounds, antioxidants and completely different effects on the body and brain.
Comparison in numbers: What is in our teaspoon? When comparing professionally, values are checked per 100 grams of dry powder (even though in practice we only use a teaspoon).
Natural cocoa (unsweetened): Contains on average about 229 calories per 100 grams, with a good presence of protein (about 20 grams) and quality fat (about 14 grams).
Instant coffee dry: Contains about 350 calories per 100 grams. It is indeed rich in protein (about 12 grams), but contains almost no fat.
Bottom line: In one teaspoon the caloric differences are negligible. The real "weight" of your cup will be determined by what you add around it – the amount of milk, sugar or sweetener.
Caffeine: Who wakes you up more - and who is suitable for the evening? Instant coffee contains a very high concentration of caffeine - on average over 3,000 mg per 100 grams of powder. In practice, in one cup this is usually about 40-80 mg of caffeine, depending on the amount of powder.
Cocoa, on the other hand, contains only about 200–250 mg of caffeine per 100 grams, meaning that in a tablespoon of cocoa there are around 10–12 mg of caffeine. A very significant difference. Cocoa also contains theobromine - a substance from the same family as caffeine, but with a more gentle and prolonged effect.
It is less "jumpy", raises the heart rate less, and is sometimes experienced as a calmer stimulant. This is one of the reasons cocoa may be more suitable for the evening, especially for those sensitive to caffeine. Of course, this is not a sleeping pill, but in terms of caffeine load - it is gentler.
Antioxidants: Not who has more - but what type:
Both coffee and cocoa are rich in polyphenols, but of different types and with different (positive) effects on the body.
In coffee: Chlorogenic acids and other antioxidants that have been widely studied are found. Reviews published in "Nutrients" and in "Journal of Clinical Nutrition" found a connection between moderate coffee consumption and a reduced risk of several chronic diseases, including metabolic diseases and some types of cancer.
In cocoa: Flavanols are found, which have been studied in the context of blood vessel and heart health. Studies published in "Nutrients" and in "American Journal of Clinical Nutrition" found that consumption of cocoa rich in flavanols was linked to improvement in vascular function measures and a slight reduction in blood pressure.
Coffee, brain and risk of Alzheimer’s: Recently, studies have accumulated that found a connection between moderate coffee consumption and a lower risk of Alzheimer’s and cognitive decline. A review that was recently in the headlines and published in "Journal of Alzheimer’s Disease" showed that consumption of 1-4 cups of instant coffee per day was linked to a reduction in risk, while very high consumption did not show an additional advantage.
How does this happen? It is hypothesized that there is an anti-inflammatory and antioxidant effect of coffee, as well as an effect on energy pathways in the brain. In any case, it should be remembered that the effect is not unlimited. Excess caffeine may harm sleep, and quality sleep is a central factor in maintaining memory over time.
Cocoa, heart and blood vessels: Cocoa has been studied extensively דווקא in other contexts, mostly in the field of heart health. Flavanols from cocoa can improve endothelial function (the lining of blood vessels) and slightly reduce systolic and diastolic blood pressure. The effect is not dramatic, but consistent: It can contribute to a certain reduction in blood pressure, especially with regular consumption of cocoa rich in flavanols.
You do not have to choose – you can vary: Those who drink several cups of coffee a day and feel a rapid heartbeat, nervousness or less good sleep can consider replacing the afternoon coffee - with a cup of hot cocoa. This way you also get a variety of antioxidants, reduce caffeine load, and maintain a warm and pleasant ritual.
Nutritional health is not a question of “either-or”, but of personal adjustment.
How to prepare light cocoa like instant coffee? So that the cocoa does not turn into a sugar-rich chocolate drink, you can prepare it just like instant coffee, in a simple way: A teaspoon of quality cocoa, a little hot water for initial mixing, and then adding hot water or low-fat milk/soy drink.
You can add cinnamon, vanilla or a calorie-free sweetener. This way you get a hot, heavy and satisfying drink, rich in flavor, with almost no added calories - and with less caffeine than coffee. So in conclusion the real question is not what is "healthier", because both are excellent. The question is what suits you - and the time of day when you drink it.
