Both broccoli and cauliflower are cruciferous powerhouses, known for being low-calorie and nutrient-dense additions to any diet. They are often discussed interchangeably in healthy recipes, especially low-carb or keto-friendly options. While their overall nutritional profiles are remarkably similar, a closer look reveals some interesting differences, particularly when it comes to their natural sugar content.
The Sugar Verdict: Raw vs. Raw
When comparing raw broccoli and raw cauliflower on an equal weight basis, cauliflower holds a slight edge in total sugar content. Per 100 grams of raw vegetable, cauliflower contains approximately 1.9 grams of sugar, while broccoli contains about 1.7 grams. This difference is minimal, and both vegetables remain excellent, low-sugar choices for most dietary needs, including those focusing on blood sugar management or weight loss.
The Specifics of Sugar Content
It's also interesting to note the types of sugars present in each. The sugars found in raw cauliflower are primarily glucose and fructose. Raw broccoli, however, contains a broader spectrum of natural sugars, including fructose, glucose, and sucrose, with trace amounts of maltose and lactose. For most individuals, this distinction is irrelevant, but it highlights the subtle chemical differences between these two closely related vegetables.
A Broader Look at Macronutrients
Beyond just sugar, a full macronutrient comparison provides a more complete picture of what each vegetable offers. Per 100 grams, broccoli is slightly higher in calories, protein, and carbohydrates, while also being richer in dietary fiber. Cauliflower contains slightly less of these macronutrients.
- Calories: A 100g serving of raw broccoli contains about 34 calories, compared to cauliflower's 25 calories.
- Carbohydrates and Fiber: Raw broccoli has approximately 6.6g of carbs, with 2.6g of that being dietary fiber. Raw cauliflower has around 5g of carbs and 2g of fiber. This translates to a small difference in net carbs, which is the total carbs minus the fiber.
- Protein: Raw broccoli contains more protein per 100g (2.8g) than raw cauliflower (1.9g).
- Fat: Both vegetables are extremely low in fat, with less than 0.5g per 100g.
A Side-by-Side Nutritional Showdown
To make the comparison clearer, here is a table outlining the key nutritional differences per 100g of raw vegetable, based on available data.
| Nutrient (per 100g, raw) | Broccoli | Cauliflower |
|---|---|---|
| Calories | ~34 kcal | ~25 kcal |
| Protein | ~2.8 g | ~1.9 g |
| Carbohydrates | ~6.6 g | ~5.0 g |
| Sugar | ~1.7 g | ~1.9 g |
| Dietary Fiber | ~2.6 g | ~2.0 g |
| Vitamin C | ~89 mg | ~48 mg |
| Vitamin K | ~101 µg | ~15.5 µg |
| Folate | ~63 µg | ~57 µg |
| Choline | ~18.7 mg | ~44.3 mg |
Beyond Macronutrients: Micronutrients and Health Benefits
While the sugar difference is negligible, other nutritional variations might influence your choice based on specific health goals. Both vegetables are rich in essential vitamins, minerals, and powerful antioxidants, but the balance differs.
Antioxidant Powerhouses
- Broccoli is a standout for its high levels of vitamins C and K, and contains vitamin A, which is absent in cauliflower. It is also known for compounds like sulforaphane, which has potent anti-cancer and anti-inflammatory properties.
- Cauliflower contains significant amounts of vitamin C, but its claim to fame is a higher concentration of choline, an essential nutrient important for brain health and metabolism. Like broccoli, it also contains health-promoting antioxidants, including glucosinolates.
Mineral Content
Broccoli contains higher levels of minerals like calcium, iron, zinc, and phosphorus. Cauliflower, on the other hand, contains higher amounts of choline. Ultimately, incorporating a mix of both into your diet is the best strategy to maximize your nutrient intake, as each offers a unique mix of beneficial compounds.
Culinary Uses and Dietary Considerations
Both vegetables are incredibly versatile, making them staples for many different diets. The minimal sugar and carb content make them perfect for low-carb and ketogenic diets, serving as excellent substitutes for higher-carb foods like rice and potatoes.
- Cauliflower's Versatility: With its neutral flavor, cauliflower is a popular alternative for grains and starches. It can be riced, mashed, or turned into pizza crust, offering a low-calorie, low-carb foundation for many dishes.
- Broccoli's Hearty Texture: Broccoli's texture and slightly stronger flavor profile make it a satisfying addition to stir-fries, salads, and casseroles. Both vegetables hold up well to various cooking methods, though steaming is often recommended to retain the most nutrients.

Conclusion: The Best Choice for a Healthy Diet
When it comes to the question of which has more sugar, broccoli or cauliflower?, the answer is that cauliflower has a slightly higher sugar content, but the difference is so marginal that it should not be a deciding factor for most people. Both are exceptionally healthy, low-sugar, low-calorie, and nutrient-dense vegetables. The best approach for a well-rounded and nutritious diet is to incorporate both broccoli and cauliflower, as they provide slightly different mixes of vitamins, minerals, and antioxidants. Your ultimate choice should be based on your flavor preferences and culinary needs, knowing that either option is a fantastic and healthy one.
