How Many Calories in 1 Head of Broccoli? Nutrition Facts

How Many Calories are in 1 Head of Broccoli?

Broccoli is one of the most nutritious vegetables you can eat. But many people wonder just how many calories this green superfood contains. Here is a detailed look at the calorie count and nutritional profile of broccoli.

Calories in 1 Head of Raw Broccoli

One head of broccoli weighing approximately 1 pound or 16 ounces (454g) contains about:

• 111 calories
• 34 calories from fat
• 77 calories from carbohydrates

So in total, there are 111 calories in 1 pound of raw, uncooked broccoli florets and stalks.

Calories in 1 Cup of Raw Broccoli Florets

If you measure out broccoli by the cup, 1 cup of chopped raw broccoli florets contains:

• 31 calories
• 9 calories from fat
• 22 calories from carbs

There are approximately 3 cups of florets in 1 pound or head of broccoli. So 3 cups would equal 93 calories, the same as 1 full head.

Calories in 1 Cup of Raw Broccoli Stalks

The stalks are denser and contain slightly more calories per cup than the florets. One cup of raw broccoli stalks has about:

• 18 calories
• 4 calories from fat
• 14 calories from carbs

Combine about 2 cups of stalks with 3 cups of florets to make up an entire head of broccoli.

Nutritional Profile of 1 Head of Broccoli

Broccoli provides this approximate nutritional profile per 1 pound or 16 ounce head:

• Protein: 12g
• Carbs: 34g
• Fiber: 16g
• Sugar: 10g
• Fat: 1.3g
• Vitamin C: 220% DV
• Vitamin K: 270% DV
• Vitamin A: 20% DV
• Folate: 28% DV
• Potassium: 21% DV

Broccoli is especially high in vitamins C and K. It also provides fiber, antioxidants, and phytonutrients like glucosinolates and sulforaphane that offer health benefits.

Benefits of Broccoli

With its outstanding nutrient profile, regularly eating broccoli provides many benefits:

Supports Immune Function

The vitamin C content helps strengthen the immune system and fights viruses, infections, and common colds. Just 1 cup of broccoli florets meets over 130% of the recommended daily vitamin C intake.

Powerful Antioxidant Effects

Broccoli is rich in antioxidants like vitamins C and E, beta-carotene, kaempferol, and quercetin that neutralize damaging free radicals to reduce inflammation and prevent chronic disease.

May Help Prevent Cancer

The sulforaphane in broccoli boosts liver detoxification enzymes and acts as a natural anti-carcinogen that may suppress tumor growth and cell mutation at early stages of cancer development.

Supports Heart Health

The anti-inflammatory nutrients in broccoli help keep blood vessels healthy and lower cholesterol levels. The folate also prevents buildup of homocysteine linked to heart disease.

Aids Blood Sugar Control

The fiber causes a slower, more steady release of sugar into the bloodstream. The chromium helps regulate insulin action as well, supporting diabetes management.

Promotes Digestive Regularity

The large amount of insoluble fiber softens stool and increases bowel movements to prevent constipation. The sulforaphane may also protect gut lining cells.

Strengthens Bones

The vitamin K1 improves calcium absorption for denser bones. The potassium and magnesium also help retain bone mineral density as we age.

Potential Health Risks

Broccoli is safe for most people when consumed in normal food amounts. But there are some potential health risks to consider at very high intakes:

Thyroid Problems

Very high cruciferous vegetable intake may impair thyroid function in those with iodine deficiency. Limit broccoli to 1-2 cups per day if you have a thyroid disorder.

Blood Thinning

Large amounts of broccoli could make the effects of blood thinning drugs stronger due to the vitamin K content. Monitor your medication dosage and consult your doctor if concerned.

Kidney Stones

For those prone to oxalate-containing kidney stones, excessive broccoli consumption might increase stone development risks. Eat broccoli in moderation if you have a history of calcium oxalate stones.

Gas and Bloating

Some people experience gas, bloating, or intestinal discomfort from broccoli due to sulfur-containing compounds and raffinose sugars. Cooking broccoli may help reduce digestive upset for sensitive individuals.

How Much Broccoli Should You Eat Per Day?

The recommended daily intake of broccoli is:

• 1-2 cups cooked or raw per day for most adults
• 1 cup cooked broccoli for children ages 1-3
• 1.5 cups cooked broccoli for children ages 4-8
• 2-2.5 cups cooked broccoli for children ages 9-18

Eating 1-2 pounds or heads of broccoli per week can provide significant health benefits without exceeding dietary limits.

Benefits Maximized at 1-3 Cups Per Day

Research found the antioxidant, anti-cancer, and cholesterol-lowering benefits peaked at around 1–3 cups of broccoli per day. Larger amounts did not increase advantages further.

Avoid Exceeding 2 Pounds Per Day

Consuming more than 2 pounds heads of broccoli daily long-term may impair thyroid function or nutrient absorption for some individuals. Stay within recommended portions.

Tips for Cooking Broccoli

Cooking broccoli properly preserves nutrients while enhancing flavor:

Steaming

Steaming for 3-4 minutes is ideal for retaining nutrients and texture. Avoid over-steaming into mush.

Stir-Frying

Stir-frying broccoli for 2-3 minutes in olive oil or avocado oil boosts carotenoid absorption.

Roasting

Roasting broccoli florets for 15-20 minutes at 400°F caramelizes natural sugars for added sweetness.

Microwaving

Microwaving broccoli with a little water for 3-4 minutes provides a quick cooking method.

Blanching

Blanching broccoli in boiling water for 1 minute helps retain nutrients when freezing for later use.

Avoid Overcooking

Whichever cooking method used, ensure broccoli is not overcooked into a mushy texture. This destroys nutrients and flavor.

Making Broccoli Tastier

To make broccoli more enjoyable:

Seasonings

Sprinkle with garlic powder, onion powder, paprika, lemon juice, pepper, or parmesan before roasting or sautéing.

Toppings

Drizzle with olive oil or avocado oil-based sauces. Add spice with red pepper flakes or sriracha.

Pairings

Serve broccoli alongside proteins like chicken, beef, fish, or tofu to make a balanced meal.

Cooking Methods

Roast or stir-fry instead of boiling to add caramelized, crispy texture.

Cheese Additions

Grate cheddar, feta, parmesan, Swiss, or goat cheese over steamed or roasted broccoli.

How to Store Broccoli Properly

Follow these storage tips to keep broccoli fresh for longer:

Refrigerate Promptly

Store unwashed broccoli in a perforated plastic bag in the refrigerator crisper within an hour of purchasing.

Don't Wash Before Storing

Washing before storage causes premature spoilage. Keep unwashed until ready to use.

Use Within 5-7 Days

For best quality, use raw broccoli heads within a week of buying. The stalks deteriorate faster than florets.

Cut Florets From Stalks

Remove florets from stalks and store separately for longer lifespan. The stalks release ethylene gas to hasten ripening.

Blanch Before Freezing

For freezer storage, first blanch broccoli 2-3 minutes then immediately ice bath or freeze. Frozen broccoli florets keep 6-8 months.

Can Dogs Eat Broccoli?

Broccoli is safe for dogs to eat in moderation. Potential benefits include:

• Vitamin, mineral, and fiber source
• Antioxidants for cell health
• Chlorophyll may reduce cancer risks
• Supports heart, immune system, and digestion

Feed broccoli florets or pieces of stalk cooked or raw. Limit to 10% of daily calories to avoid gas or upset stomach.

The Bottom Line

An entire head of broccoli contains only about 110 calories but provides a powerhouse of nutrition including vitamins, minerals, antioxidants, and fiber. Eating broccoli regularly offers anti-cancer, heart healthy, anti-inflammatory, and digestive benefits with minimal caloric impact.
