What are the Side Effects of Dalgona Coffee?

4 min read

In 2020, Dalgona coffee became a social media sensation, with millions whipping up this visually appealing beverage at home. However, despite its simple and seemingly harmless ingredients—instant coffee, sugar, and milk—the drink can come with a range of surprising side effects, particularly with excessive consumption.

Quick Summary

An over-consumption of Dalgona coffee can lead to several health issues due to its high caffeine and sugar content, including anxiety, insomnia, stomach problems, and blood sugar spikes. Certain individuals with pre-existing conditions are at a higher risk of adverse reactions.

Key Points

  • High Caffeine Content: Standard recipes can deliver a large dose of caffeine, potentially causing jitters, anxiety, and sleep disruption.

  • Excessive Sugar Intake: The equal parts sugar in many recipes can lead to significant blood sugar spikes, energy crashes, and weight gain over time.

  • Gastrointestinal Distress: The high acidity and caffeine can trigger or worsen symptoms of acid reflux and heartburn in sensitive individuals.

  • Risk for Pre-existing Conditions: People with heart issues, diabetes, or anxiety disorders should be particularly cautious due to caffeine and sugar impacts.

  • Modification Options Available: Side effects can be mitigated by using decaf coffee, reducing sugar, or opting for dairy-free milk alternatives.

Understanding Dalgona Coffee's Ingredients

At its core, Dalgona coffee is a whipped concoction of equal parts instant coffee, granulated sugar, and hot water, which is then dolloped over milk. While the recipe seems straightforward, the key to its fluffy texture lies in the high concentration of both instant coffee and sugar used to create the stiff foam. This concentration is where many of the potential side effects originate.

The Impact of High Caffeine Content

Instant coffee generally contains a significant amount of caffeine, and standard Dalgona recipes often use two or more tablespoons per serving, creating a potent dose. For example, some recipes can pack over 270mg of caffeine into a single glass. This can have a variety of physiological effects on the body.

  • Anxiety and Jitters: High doses of caffeine can trigger the release of adrenaline, causing nervousness, shakiness, and heightened anxiety, especially in caffeine-sensitive individuals.
  • Insomnia: Consuming too much caffeine, particularly later in the day, can interfere with your sleep cycle and cause insomnia.
  • Increased Heart Rate: Caffeine is a stimulant that can increase heart rate and blood pressure, which is a concern for people with pre-existing heart conditions.
  • Dependency: Regular, high-dose consumption can lead to caffeine dependency, resulting in withdrawal symptoms like headaches and fatigue if intake is suddenly reduced.

The Health Concerns of Excessive Sugar

Many traditional Dalgona recipes call for one to two tablespoons of sugar per serving. With two tablespoons, that's up to 24 grams of added sugar in a single drink, which is a significant portion of the daily recommended limit.

  • Blood Sugar Spikes: The high sugar load can cause a rapid spike in blood sugar levels, followed by a subsequent "crash" that leads to fatigue and mood swings. This is particularly risky for individuals with diabetes or insulin resistance.
  • Increased Calorie Intake: The combination of sugar and milk can make Dalgona coffee a high-calorie indulgence. Over time, frequent consumption can contribute to weight gain.
  • Inflammation and Chronic Disease: Diets high in added sugar are linked to chronic inflammation, which is a risk factor for heart disease.

Comparison of Dalgona and Regular Coffee

To put the nutritional content into perspective, it is useful to compare a standard Dalgona recipe with a typical cup of brewed coffee.

Feature Standard Dalgona Coffee (approx.) Plain Black Brewed Coffee (8oz)
Caffeine Content High (often >150mg) Moderate (95-200mg)
Added Sugar High (24g+) Zero
Calories High (200+) Low (2-5 calories)
Fat Content Moderate (from milk) Negligible
Digestive Impact Potential for higher acidity, lactose issues Moderate acidity
Preparation Effort Requires vigorous whipping Simple brewing

Digestive and Other Potential Issues

Beyond caffeine and sugar, the specific ingredients can cause other problems for certain individuals.

  • Acid Reflux and Heartburn: Coffee's natural acidity can stimulate increased gastric acid secretions, leading to heartburn and acid reflux, especially for those prone to gastrointestinal issues. The higher concentration of coffee in Dalgona can aggravate these symptoms.
  • Lactose Intolerance: Traditional Dalgona coffee is served over milk. For people with lactose intolerance, this can lead to uncomfortable digestive symptoms like bloating and gas. Fortunately, alternatives like oat milk or almond milk can mitigate this issue.
  • Dehydration: High caffeine intake acts as a diuretic, increasing urination and potentially leading to dehydration if not balanced with sufficient water intake.

Mitigating Side Effects for Responsible Enjoyment

If you enjoy Dalgona coffee, there are several ways to reduce the risk of side effects while still savoring the drink. Moderation is key, but altering the recipe can also make a big difference.

  • Reduce Sugar: Use less sugar or substitute it with a natural, low-calorie sweetener like stevia or monk fruit powder to avoid blood sugar spikes and excessive calorie intake.
  • Control Caffeine: Use decaffeinated instant coffee to enjoy the whipped texture without the caffeine-related side effects like anxiety and insomnia. This is a simple and effective way to make the drink safer for sensitive individuals.
  • Consider Alternatives: Swap instant coffee for other whipped drinks, like a Dalgona hot chocolate made with cocoa powder, which provides a similar frothy texture without the high caffeine content.
  • Choose Dairy-Free Milk: For those with lactose intolerance, using plant-based milk alternatives is an easy fix that doesn't compromise the drink's appeal.

Conclusion

Dalgona coffee, while a visually appealing and satisfying trend, is not without its potential health drawbacks. The side effects are largely attributed to the high concentration of caffeine and added sugar inherent in many traditional recipes. These can lead to issues ranging from minor inconveniences like jitters and blood sugar crashes to more serious concerns like heart palpitations and exacerbated acid reflux. The good news is that with simple modifications, such as using less sugar or opting for decaf instant coffee and dairy alternatives, you can significantly reduce these risks. By being mindful of your intake and personal sensitivities, you can still enjoy this trendy beverage as an occasional treat rather than a daily habit.
