Broccoli Vs Steak Protein Per 100 Calories | Smart Protein Tradeoffs

Per 100 calories, steak gives on average around twice as much protein as an equal-calorie serving of broccoli.

When you compare broccoli and steak on a plate, steak looks like the obvious protein star. Once you line them up calorie for calorie, though, the picture gets more interesting. Both foods carry protein, just in different packages.

Why Protein Per 100 Calories Matters

Two foods can share the same protein per 100 grams but have very different calorie counts. In that case, the leaner food gives more protein for the same energy, and that view often changes which food looks like the better protein choice.

Protein is made from amino acids. Steak covers all the amino acids that the body cannot make on its own, so it counts as a complete protein. That is one reason beef sits at the center of many high-protein diets, and why cuts like top sirloin offer a strong mix for muscle repair and maintenance.

Broccoli does not hit the same amino acid balance by itself, and the total protein per serving is smaller. That said, it still contributes helpful amino acids across the day, especially when you pair it with grains, beans, tofu, or dairy. The whole pattern of your meals matters more than any single food.

Protein helps many people stay satisfied between meals, but it is not the only piece of that puzzle. Broccoli brings fiber and a high water content, which can stretch the stomach and slow digestion. That combination can make a plate with a modest amount of steak feel much more filling when you also load it with vegetables.

Broccoli Vs Steak Protein Per 100 Calories: Core Numbers

To compare broccoli and steak clearly, it helps to start with consistent data. Nutrition databases such as Nutrition Facts For Raw Broccoli and Nutrition Facts For Beef Top Sirloin compile values drawn from laboratory analysis of typical samples.

From these datasets and related USDA entries, raw broccoli contains about 34 calories and 2.8 grams of protein per 100 grams, while raw beef top sirloin sits near 177 calories and 30.8 grams of protein per 100 grams. Put on a per-calorie basis, that works out to about 8.3 grams of broccoli protein and about 17.4 grams of steak protein per 100 calories.

Protein Per 100 Calories Comparison Table

The table below uses widely cited nutrition data to compare protein per 100 calories for broccoli, steak, and a few other common protein foods. Values are rounded for simplicity.

On a pure protein-per-calorie basis, steak sits closer to chicken breast than to broccoli. Broccoli lands near lentils, which are known as a helpful plant protein source. Tofu sits between them, with more protein per 100 calories than broccoli but less than steak.

Broccoli’s Strengths Beyond Protein

If you only compare broccoli and steak on protein per 100 calories, steak wins. Once you widen the lens to vitamins, minerals, and other nutrients, broccoli brings a long list of benefits that meat does not match. That is why USDA FoodData Central and the current Dietary Guidelines For Americans 2025–2030 both treat vegetables as a separate, mandatory food group instead of a side note.

Together, the two foods give you something close to a “best of both worlds” plate. Steak brings dense, complete protein and readily absorbed iron, while broccoli piles on fiber, potassium, and vitamin-rich volume. When you pair them, you can keep calories under control and still feel nourished instead of chasing protein with nothing green on the side.

Fiber, Volume, And Meal Satisfaction

Broccoli delivers dietary fiber with very few calories. A large cooked serving can give you several grams of fiber, which helps bowel regularity and slows the digestion of the rest of the meal. Steak contains no fiber at all, so it cannot fill that role.

Broccoli is also bulky and water-rich. A 100-calorie portion of broccoli takes up far more plate space than 100 calories of steak. Many people find that a tall pile of vegetables next to a modest piece of meat leaves them more satisfied than a plate dominated by meat alone.

Micronutrients And Protective Compounds

Broccoli stands out for vitamin C, vitamin K, folate, and potassium. It also carries glucosinolates and related sulfur compounds that researchers study for links with heart and metabolic health. Beef, by contrast, shines for vitamin B12, zinc, and heme iron, which the body absorbs easily.

In practice, each food covers different jobs in the diet. Instead of asking whether broccoli can replace steak as a protein source, it often helps more to ask how steak and broccoli together can cover more nutrient bases than either would alone.

How Steak’s Protein Density Helps

Steak gives a lot of protein in a small calorie package, especially when you pick lean cuts and trim visible fat. That makes beef handy for people who lift weights, train for strength sports, or just want to keep muscle while dropping body fat.

Current discussions around protein needs, including recent articles from Harvard T.H. Chan School Of Public Health, point toward higher daily protein targets for many adults than older guidelines suggested. Steak can help reach those targets without a mountain of food.

Complete Protein In Fewer Bites

A modest 150-gram cooked sirloin steak can approach 300 calories but carry well over 40 grams of complete protein, depending on trim level and cooking method. You would need far more than 300 calories of broccoli to reach the same protein target, and even then you would still need other foods to round out the amino acid pattern.

That does not mean you must eat steak to meet protein needs. Many people reach high protein intakes with combinations of dairy, poultry, eggs, fish, beans, lentils, whole grains, tofu, and yogurt. Steak is simply one dense option on that list.

Iron, B Vitamins, And Energy Levels

Red meat carries heme iron, a form the body absorbs well. It also contains B vitamins such as B12, B6, and niacin. People who feel drained when iron or B12 intake drops sometimes find that thoughtful use of lean beef, alongside other iron sources, helps them feel better again.

Broccoli contains iron too, but in a non-heme form that the body does not absorb as easily. It still counts toward your daily iron total, especially when you pair it with vitamin C sources, yet it cannot fully match the iron punch of steak on a per-calorie basis.

Broccoli And Steak In Real-World Meals

Numbers on a chart are useful, but people eat meals, not spreadsheets. Broccoli and steak fit into meals in very different ways, and that has as much influence on your results as the lab values.

For Muscle Gain And Strength Training

If you lift regularly and want more muscle, the main goal is hitting your daily protein target and total calories while keeping an eye on health markers. Lean steak can make that target easier because it packs so much protein into each 100 calories.

A simple template many lifters use is to build a plate with a palm-sized portion of steak, a big pile of broccoli or other vegetables, and a serving of starch such as potatoes or rice. The steak gives most of the protein, the vegetables add volume and micronutrients, and the starch keeps energy levels up for training.

For Weight Loss And Appetite Management

When weight loss is the priority, people often benefit from meals that feel solid while keeping calories in check. Here, broccoli and steak together can work better than either on its own. Steak brings the protein density, while broccoli lets you expand the meal size without many extra calories. That mix helps the meal feel more satisfying.

For Heart And Metabolic Health

Large observational studies suggest that diets with more plant protein and less red meat line up with better heart outcomes over time. Publications from groups such as the Harvard Health Publishing team point in that direction, even when total protein stays the same.

That does not mean steak has no place for heart-conscious eaters. It does suggest that many people may do well with smaller portions of lean steak, more fish and poultry, and generous servings of vegetables and beans. Broccoli fits neatly into that pattern as a fiber-rich, low-calorie side that still adds a bit of protein.

Broccoli And Steak Nutrition Summary Per 100 Calories

Balanced Takeaway On Broccoli Vs Steak Protein

Steak clearly offers more protein per 100 calories than broccoli. On a gram-for-gram calorie basis, lean cuts like top sirloin act as concentrated protein sources that can help you hit ambitious targets without overshooting your energy needs.

Broccoli, though, brings fiber, key vitamins, minerals, and plant compounds while still adding a modest amount of protein for very few calories. In real meals, that means broccoli pairs well with steak: the steak carries the heavy protein load, and the broccoli keeps the plate light, colorful, and nutrient dense.

If you enjoy both foods and have no medical reason to avoid either, you do not have to pick a winner. Use steak when you need more protein in less food, and lean on broccoli when you want to add volume, fiber, and extra nutrients without many calories. The best “protein per 100 calories” plan is the one that fits your tastes, your health goals, and your long-term eating habits.
