The Highest Carbohydrate Foods by Dry Weight
When evaluating the highest carbohydrate foods, the method of measurement is crucial. By dry weight, some of the most concentrated sources are milled grains, stripped of moisture and most other nutrients during processing. According to nutritional data, both corn flour and white flour emerge as two of the most carbohydrate-dense foods available.
Corn Flour and White Flour Explained
Corn flour, made from finely ground whole cornmeal, is a staple ingredient in many culinary traditions. Per 100 grams, it can contain around 79.1 grams of carbohydrates, making it an exceptionally dense source of energy. This high concentration is due to the process of grinding and refining, which removes moisture and fiber, leaving behind a highly concentrated starch. Similarly, refined white flour contains approximately 75.1 grams of carbohydrates per 100 grams, a result of removing the bran and germ, which contain much of the fiber and nutrients. While both provide significant energy, their refined nature means they offer very little in terms of fiber and other vital nutrients, leading to rapid digestion and potential blood sugar spikes.
Carbohydrate-Rich Staples in Cooked Form
For most people, the question of which two foods contain the most carbohydrates pertains to staples in their cooked form. Here, the landscape shifts from dry ingredients to prepared meals. Rice and pasta are contenders for the title of highest-carb staples in a typical meal.
Rice vs. Pasta
Both rice and pasta are foundations of diets worldwide and pack a significant carbohydrate punch when cooked. A cup of cooked white rice can contain upwards of 45-53 grams of carbohydrates, while a cup of cooked pasta typically contains around 30-45 grams. The difference often depends on the specific variety and preparation method. Brown rice and whole wheat pasta are healthier alternatives, providing more fiber and a slower energy release due to their higher fiber content. In contrast, white rice and pasta are considered refined carbohydrates and can have a higher glycemic index.
Complex vs. Simple Carbohydrates: A Crucial Distinction
Not all carbohydrates are the same, and distinguishing between them is key to a healthy diet. Carbohydrates are broadly classified into simple and complex types, based on their chemical structure and how quickly they are digested.
- Simple Carbohydrates: These are quick-digesting carbs like sugars. They are found naturally in fruits and milk but are also prevalent in added sugars in processed foods and drinks, causing rapid spikes in blood sugar.
- Complex Carbohydrates: These are longer chains of sugar molecules that take longer to digest, providing a more stable and sustained release of energy. They are rich in vitamins, minerals, and fiber and are found in whole grains, legumes, and starchy vegetables.
Comparing Common High-Carbohydrate Foods
To help illustrate the differences in carbohydrate content and overall nutritional value, here is a comparison of several common carb-heavy foods.
| Food (per 100g dry/cooked) | Carbohydrates (g) | Fiber (g) | Type of Carb | Glycemic Index (GI) |
|---|---|---|---|---|
| White Flour (dry) | 75.1 | 2.3 | Refined Complex | High (approx 70) |
| Corn Flour (dry) | 79.1 | 5.5 | Refined Complex | High (approx 85) |
| Cooked White Rice (1 cup) | 45-53 | 0.5-1.6 | Refined Complex | High (approx 73) |
| Cooked White Pasta (1 cup) | 30-45 | 1.8 | Refined Complex | Low-Medium (approx 49) |
| Cooked Potato (1 medium) | 25-30 | 2-3 | Complex | High (approx 73-82) |
Making Healthier Carb Choices
While some foods contain high levels of carbohydrates, the quality of those carbohydrates is what truly matters for your health. Focusing on nutrient-dense, fiber-rich sources is the key to maintaining energy, controlling blood sugar, and supporting digestive health.
- Opt for Whole Grains: Replace refined grains like white bread and rice with their whole-grain counterparts, such as brown rice, whole-wheat pasta, oats, and quinoa.
- Load up on Legumes: Beans, lentils, and peas are packed with complex carbs and fiber, promoting satiety and stable blood sugar levels.
- Eat Your Veggies: Starchy vegetables like sweet potatoes and non-starchy varieties like leafy greens and broccoli offer vital nutrients and fiber alongside their carbohydrate content.
- Limit Added Sugars: Cut back on foods and drinks with high amounts of added sugars, which provide little nutritional value and can contribute to weight gain and disease.
How to Assess Carb Content on Food Labels
When reading a nutrition label, understanding the different carbohydrate components is important for managing your intake. The Total Carbohydrate value includes starches, fiber, and sugars. For those tracking digestible carbs, you can subtract the fiber content from the total amount. Note that added sugars are also listed separately, allowing you to identify sources of low-nutrient carbs.

Conclusion
Identifying which two foods contain the most carbohydrates depends on whether you consider raw ingredients or cooked staples. By dry weight, corn flour and white flour are exceptionally carb-dense. However, for everyday meals, rice and pasta serve as significant high-carb sources. More important than pinpointing the top two is recognizing that the source and quality of your carbohydrates dictate their impact on your health. Prioritizing whole-food sources like legumes, whole grains, and vegetables will provide the energy your body needs along with essential fiber, vitamins, and minerals. Healthy carbohydrate choices are about quality, not just quantity.
