Calorie and Macronutrient Breakdown
When comparing the caloric content of staple foods, it's essential to look at the cooked product, as preparation significantly impacts the final nutritional value. For a direct comparison, a 100-gram serving is the standard measure.
Cassava vs. Rice: Calorie and Carb Snapshot
Cassava, a starchy root vegetable, is notably more energy-dense than cooked white rice. Per 100 grams, cooked cassava provides approximately 160–191 calories, whereas cooked white rice contains about 130 calories. This difference is largely due to variations in water and carbohydrate content. Cassava has a higher percentage of carbohydrates by weight compared to cooked rice. While both provide a good source of energy, cassava's higher carbohydrate load makes it a more calorie-dense food option.
Macronutrient Profile Comparison
Beyond calories, the distribution of macronutrients—carbohydrates, protein, and fat—is a key point of comparison. As shown in the table below, both are predominantly carbohydrate sources but vary slightly in other areas.
| Nutrient (per 100g, cooked) | Cassava | White Rice | Brown Rice |
|---|---|---|---|
| Calories | 160-191 kcal | ~130 kcal | ~112 kcal |
| Carbohydrates | 38-40 g | ~28 g | ~24 g |
| Protein | 1.4-1.5 g | 2.7 g | 2.6 g |
| Fat | 0.3 g | 0.3 g | 0.9 g |
| Fiber | 1.8-2 g | 0.4 g | 1.8 g |
The Role of the Glycemic Index
The glycemic index (GI) measures how quickly a carbohydrate-containing food raises blood sugar levels. This is a critical factor for individuals managing diabetes or controlling weight. The GI of both cassava and rice can vary significantly based on variety and preparation method. For instance, some preparations of boiled cassava can have a high GI, but others, like analog rice made from cassava, can have a lower GI. Similarly, white rice typically has a medium-to-high GI, whereas brown rice has a lower GI. Cooking and processing methods directly impact a food's GI value.
Key Nutritional Differences and Health Implications
Choosing between cassava and rice depends on more than just calories; it's about the broader nutritional profile and individual health goals. Here are some key differences:
- Fiber Content: Whole-grain brown rice and appropriately processed cassava products can be good sources of fiber, which supports digestive health and prolonged feelings of fullness. However, plain white rice has very little fiber.
- Micronutrients: While white rice is often enriched with B vitamins and iron, brown rice naturally contains higher levels of magnesium and manganese. Cassava is a notable source of Vitamin C and copper. Whole-food forms of both are generally more nutritious than their highly processed counterparts.
- Resistant Starch: Cooked and cooled cassava develops resistant starch, a type of fiber that can improve digestive health and blood sugar control. Rice also develops resistant starch when cooled, offering similar benefits.
- Preparation Considerations for Cassava: It is crucial to properly prepare cassava by peeling, soaking, and cooking it thoroughly to remove harmful cyanogenic compounds. Rice does not require this specific preparation for safety.
Which Staple is Better for You?
Deciding whether cassava or rice is a better fit depends on your dietary needs and health objectives. For instance:
- If your primary goal is lower calorie intake for weight management, cooked white rice has a slight advantage on a per-100g basis. However, portion control is paramount for both.
- For higher fiber intake and more sustained energy release, brown rice is an excellent choice. Cassava products with high fiber content also offer these benefits.
- If you follow a gluten-free diet, both cassava and rice are naturally gluten-free staples.
Ultimately, a balanced diet incorporating a variety of nutrient-rich foods is recommended. Including whole-food options like brown rice or properly prepared cassava can contribute positively to your nutritional intake.

Conclusion
In conclusion, cassava does have more calories than rice per 100 grams when comparing cooked versions. This difference is driven primarily by cassava's higher carbohydrate concentration. However, a deeper nutritional comparison reveals that the health benefits of each food are complex and depend on the specific variety and how it's prepared. Brown rice offers more fiber and micronutrients than white rice, while processed cassava products can be tailored to have favorable nutritional properties. By understanding these nuances, you can make an informed choice that best suits your dietary goals.
