Macronutrient Breakdown: Raw vs. Cooked
One of the most important factors influencing the macronutrient content of broccoli is how it is prepared. Raw broccoli is a crisp, fresh source of nutrients, while cooking methods like boiling can slightly alter the nutritional profile, often due to water absorption or nutrient leaching. For those tracking their diet, knowing the difference between raw and cooked measurements is key.
Raw Broccoli Macros (1 Cup, Chopped, Approx. 91g)
A one-cup serving of raw, chopped broccoli is an excellent low-calorie option, primarily composed of water and dietary fiber. The macros for this serving are as follows:
- Carbohydrates: Roughly 6 grams, with about 2.4 grams coming from dietary fiber.
- Protein: Approximately 2.5 grams.
- Fat: A negligible amount, around 0.3 grams.
- Calories: Around 31 calories.
Cooked Broccoli Macros (1 Cup, Boiled and Drained, Approx. 156g)
When broccoli is cooked, especially boiled, it absorbs water, increasing its weight and volume for the same number of florets, which in turn can concentrate some nutrients and dilute others. A larger portion of cooked broccoli is needed to equal the amount of fiber in a smaller portion of raw broccoli, for example. The macros for a cup of cooked, boiled, and drained broccoli are higher than raw simply because a cup of cooked broccoli weighs more (approx. 156g vs 91g for raw).
- Carbohydrates: About 5.6 grams.
- Protein: Approximately 1.86 grams.
- Fat: Around 0.32 grams.
- Calories: Around 27 calories.
The Carb Story: Fiber's Role
The carbohydrate content in broccoli is not simply sugar. A significant portion of it is dietary fiber, which plays a crucial role in digestive health. This high fiber content is what makes broccoli a low-glycemic food, meaning it has a minimal impact on blood sugar levels. Fiber promotes a feeling of fullness, which can be beneficial for weight management. It also supports a healthy gut microbiome and aids in regular bowel movements. Most of the fiber found in broccoli is insoluble, helping to bulk up stool and prevent constipation.
Comparison Table: Raw vs. Cooked Broccoli (per 1 cup)
| Nutrient | Raw Broccoli (1 cup, ~91g) | Cooked Broccoli (1 cup, ~156g)* |
|---|---|---|
| Calories | ~31 kcal | ~27 kcal |
| Carbohydrates | ~6g | ~5.6g |
| Protein | ~2.5g | ~1.86g |
| Fat | ~0.3g | ~0.32g |
| Fiber | ~2.4g | ~2.57g |
*Note: Nutritional content for cooked broccoli varies based on method. Values shown are for boiled, drained broccoli, which absorbs water, changing the nutrient concentration per cup compared to raw.
Beyond Macros: Micronutrients and Health Benefits
Broccoli is celebrated far beyond its macronutrient content, as it is packed with a wide array of vitamins, minerals, and potent phytonutrients. It is an exceptionally rich source of vitamin C, an antioxidant vital for immune function and skin health. It is also high in vitamin K1, essential for blood clotting and bone health. Other important micronutrients include folate (vitamin B9), potassium, manganese, and iron.
The plant compounds in broccoli are particularly noteworthy. For example, sulforaphane is a sulfur-containing compound that may offer protective benefits against various types of cancer by reducing oxidative stress. The presence of indole-3-carbinol, kaempferol, and quercetin also contributes to broccoli's anti-inflammatory and antioxidant properties.

Conclusion
A single cup of broccoli, whether raw or cooked, is a nutritional powerhouse with very favorable macros. It offers a low-calorie, low-fat profile, with carbohydrates primarily consisting of healthy dietary fiber. While cooking slightly alters the density of nutrients due to water content, it remains a fantastic source of vitamins, minerals, and unique plant compounds with significant health benefits. Incorporating broccoli into your diet is a simple and effective way to boost your overall nutrient intake, support digestive health, and potentially reduce the risk of certain chronic diseases.
