The Viral Myth vs. The Nutritional Reality
For years, a viral graphic has circulated suggesting that a 20-ounce bottle of soda contains the same amount of sugar as six donuts. While a comparison of specific products may show this to be true for sugar grams, it is a misleading oversimplification of their overall nutritional impact. The primary issue is that this simple equivalence ignores other critical factors, such as calories from fat, the type of sugar, and how the body metabolizes liquid versus solid food. A nutritional breakdown of these two popular indulgences reveals a far more complex picture than a simple sugar count.
Calorie and Macronutrient Breakdown
Donuts and soda are both calorie-dense, nutrient-poor items, but they get their calories from different sources. This difference is key to understanding their comparative health effects.
Donuts: A Mix of Fat, Sugar, and Refined Carbs
- Fat Content: Donuts are typically deep-fried, meaning they contain significant amounts of added fats and oils, which are calorie-dense. These are often unhealthy trans or saturated fats. Some donuts have as many calories from fat as from sugar.
- Refined Flour: The base of a traditional donut is refined all-purpose flour, which lacks fiber and nutrients. This provides a rush of simple carbohydrates to the body.
- Satiety: The combination of fat, sugar, and solid mass in a donut means it provides a sense of fullness, however temporary. It requires chewing and digestion, which engages the body differently than a liquid.
Soda: A Concentration of Liquid Sugar
- Liquid Calories: Soda's calories come almost exclusively from sugar, often high-fructose corn syrup, without any other meaningful nutrients, fiber, or fat.
- Empty Calories: Since soda provides no nutritional benefit, its calories are considered “empty.” It delivers energy without contributing to satiety, making it easy to consume a large number of calories quickly.
- Type of Sugar: The liquid sugar in soda, particularly high-fructose corn syrup, is metabolized rapidly, putting a different kind of strain on the liver and metabolic system compared to sugar from solid food.
The Metabolic Impact: Liquid vs. Solid Sugar
One of the most significant distinctions is how the body processes the sugar from each item. Liquid sugar, from sources like soda, is absorbed very quickly into the bloodstream. This causes a rapid, intense spike in blood glucose and requires a large burst of insulin production to manage. Over time, this constant metabolic stress can lead to insulin resistance and increase the risk of type 2 diabetes. Studies have even suggested that liquid sugar poses a greater risk for metabolic syndrome and cardiovascular issues than the occasional solid sweet treat.
Conversely, the sugar in a donut is absorbed more slowly due to its solid, fibrous food matrix and the presence of fat, which slows down the digestive process. While this still causes a significant blood sugar increase, it may not be as rapid or as severe as the spike from a large soda. However, this does not make the donut a healthy choice; its high fat and refined carb content present their own set of health problems.
Comparing a Typical Donut and Soda
| Feature | Average Glazed Donut | 20oz Bottle of Regular Soda |
|---|---|---|
| Calories | ~260-300 kcal | ~240-260 kcal |
| Sugar | ~12-20g | ~65g |
| Fat | ~14g | 0g |
| Carbohydrates | ~30g | ~65g |
| Primary Source | Refined flour, sugar, and fat | Liquid high-fructose corn syrup |
Long-Term Health Risks
When consumed regularly, both donuts and soda contribute to a range of chronic health issues.
- Obesity and Weight Gain: Both items provide excess calories with minimal nutritional value, leading to unhealthy weight gain.
- Type 2 Diabetes: Chronic, high intake of refined sugars from either source increases the risk of developing insulin resistance and type 2 diabetes.
- Cardiovascular Disease: High sugar intake and associated weight gain can increase the risk of heart disease.
- Liver Disease: The high amount of fructose in sugary drinks can be particularly harmful to the liver, contributing to conditions like metabolic dysfunction-associated steatotic liver disease (MASLD).
- Dental Issues: High sugar content contributes to tooth decay and cavities.
Conclusion: The Final Verdict
There is no clear winner in the debate of whether donuts are better than soda. Both are highly processed, unhealthy treats that should be limited in a healthy diet. While the sugar content might be higher in a single large soda, the total calories and fat are often higher in a single donut. The metabolic impact of rapidly absorbed liquid sugar is a significant concern with soda, but the combination of refined flour, sugar, and unhealthy fats in a donut presents its own set of dangers.
The wisest choice for your health is to replace both with more nutritious options. A truly healthy beverage choice is water, which carries no added sugars or empty calories. For a sweet treat, options like fresh fruit can provide fiber and nutrients along with natural sweetness. The core message from nutritionists is clear: understand the full nutritional picture, not just one metric, and know that frequent consumption of either item is detrimental to your health.

Choosing Healthier Options
- Substitute sugary drinks: Opt for water, unsweetened tea, or sparkling water with a splash of fruit juice instead of soda.
- Limit processed sweets: Choose whole fruits or small amounts of dark chocolate to satisfy a sweet tooth instead of donuts.
- Prioritize whole foods: Build your diet around nutrient-dense foods like whole grains, vegetables, lean proteins, and fruits.
Summary of Key Differences
- Donuts: Higher in fat and overall calories from frying. Solid form provides minimal, temporary satiety. Contain refined flour with little nutritional value.
- Soda: High concentration of liquid sugar, often high-fructose corn syrup. Causes a rapid blood sugar spike. All calories are empty and do not contribute to a feeling of fullness.
