Per 100 g cooked black beans provide about 8.9 g of protein along with fiber and slow-digesting carbs.
If you track macros, black beans quickly stand out as an easy plant protein that also brings fiber, minerals, and steady energy to the plate. Knowing black bean protein per 100g helps you plan bowls, burritos, and meal prep without guessing.
This guide walks you through how much protein 100 g of cooked black beans hold, how that compares with meat and other beans, and simple ways to turn that data into everyday meals that actually taste good.
Black Bean Protein Per 100G For Everyday Cooking
When nutrition databases talk about protein in black beans per 100 g, they usually mean plain beans that are cooked, boiled, and drained with no added fat. Based on USDA FoodData Central figures, 100 g of cooked black beans give around 8.9 g of protein, 8.7 g of fiber, and just over 130 calories.
The table below lays out the main nutrients in 100 g of cooked black beans so you can see how protein sits next to carbs, fat, and major micronutrients.
| Nutrient | Amount Per 100 g Cooked | What It Means |
|---|---|---|
| Protein | 8.9 g | Plant protein that helps muscle repair and day-to-day upkeep. |
| Dietary Fiber | 8.7 g | Helps digestion, promotes fullness, and smooths blood sugar swings. |
| Total Carbohydrate | 23.7 g | Main energy source; a large share comes from fiber and resistant starch. |
| Total Fat | 0.5 g | Almost fat free, so easy to fit into lower fat plans. |
| Calories | 132 kcal | Modest energy for the amount of protein and fiber you get. |
| Iron | 2.1 mg | Helps carry oxygen in your blood; pairs well with vitamin C sources. |
| Magnesium | 70 mg | Linked with muscle function, nerve function, and blood pressure control. |
| Folate | 149 µg | Helps normal cell growth and is helpful during pregnancy years. |
| Potassium | 355 mg | Balances sodium intake and helps keep fluid levels steady. |
For a small scoop of beans, that is a strong mix of protein, fiber, and minerals. Many people use 100 g as a base unit when they log recipes, so these numbers make it easy to build bowls and stews with a target protein range in mind.
How Black Bean Protein Stacks Up Against Other Foods
Eight to nine grams of protein per 100 g may sound modest next to foods like chicken breast, but context matters. Cooked chicken breast sits around 31 g of protein per 100 g, yet it brings almost no fiber and a different fat profile.
Black beans land in the same range as many other cooked beans. Per 100 g cooked, pinto beans hover around 9 g of protein, and lentils land around 9 g as well, so black beans fit comfortably in the usual bean range.
Compared with an egg, which holds about 6 g of protein, 100 g of black beans do slightly better on total protein and much better on fiber. The trade off is that bean protein comes with more carbs, which can be a plus or a minus depending on your training plan and blood sugar goals.
Comparing Black Beans To Other Beans For Protein
People often want to know whether black beans are a weaker or stronger protein source than nearby pantry staples. Per 100 g cooked, the spread looks like this in most nutrient databases:
- Black beans: about 8.9 g protein per 100 g cooked.
- Pinto beans: around 9.0 g protein per 100 g cooked.
- Kidney beans: around 8.7 g protein per 100 g cooked.
- Chickpeas: around 8.2 g protein per 100 g cooked.
- Lentils: around 9.0 g protein per 100 g cooked.
In short, black beans sit right in the middle of the pack. They are not the highest bean protein source you can pick, yet they are far from a weak option. Dark color also brings anthocyanins, which add an antioxidant angle that lighter beans do not match as well.
Serving Sizes: From 100G Of Black Beans To Real Plates
Measuring out 100 g on a scale works for recipe testing, but most people scoop beans with a spoon or pour them from a can. To turn the black bean protein per 100g figure into something you can eyeball in a bowl, it helps to map grams to cups and spoons.
A level half cup of cooked black beans usually weighs around 85–90 g. A full cup lands near 170–180 g. Portions in burritos, tacos, and soups often sit in that half cup to full cup range once cooked.
| Serving | Typical Cooked Weight | Typical Protein |
|---|---|---|
| Three heaped tablespoons | 50 g | 4.5 g protein |
| Level half cup | 90 g | 8.0 g protein |
| Rounded half cup | 100 g | 8.9 g protein |
| Level one cup | 175 g | 15.5 g protein |
| Bean side on a plate | 60–80 g | 5.3–7.1 g protein |
| Big chili bowl serving | 120–150 g beans | 10.7–13.4 g protein |
These ranges explain why one hearty bowl built around beans can carry the same protein as two eggs, especially when you round up the portion or mix in a second bean or lentil. If you plan meals for a household, a pot with 400 g of cooked black beans spreads about 35 g of protein across the table before you add rice, cheese, or meat.
Protein Quality And Amino Acids In Black Beans
Protein is more than a single number. It is made from amino acids, some of which your body can make and some of which it cannot. Black beans provide all nine amino acids your body cannot make on its own, though not in the same balance you see in eggs or dairy.
Studies that look at amino acid patterns in black beans note that lysine, threonine, and histidine cover adult needs well, while methionine and tryptophan sit lower. That gap is one reason classic combinations like beans with rice or corn show up in so many food traditions. Grains tend to supply more methionine, while beans lean harder on lysine, so together they add up to a strong profile over the course of a day.
For most healthy adults who eat a varied mix of plants, protein from a 100 g serving of black beans fits neatly into total daily intake. A cup of cooked beans at lunch plus other plant or animal protein at breakfast and dinner can easily reach common targets like 1.2–1.6 g of protein per kilogram of body weight for active people.
Digestibility And Satiety
Cooked black beans digest more slowly than simple starchy sides like white rice. Fiber, resistant starch, and their dense texture all slow down digestion, which tends to keep you full for longer and flatten blood sugar spikes. So while the raw protein number per 100 g sits below meat, the overall plate effect often feels more filling than the number alone suggests.
If beans are new for you or you notice gas or bloating, start with smaller servings and build up. Soaking dry beans, rinsing canned beans, and cooking them until soft all make them easier on the gut for many people.
How To Use 100G Of Black Beans In Simple Meals
Once you know the protein count for 100 g, it becomes easier to treat black beans like a basic building block. A few patterns cover most everyday meals.
Quick Lunch Bowls
Use 100 g of cooked beans as the base of a grain bowl. Add roughly the same cooked weight of rice or quinoa, toss in vegetables, and finish with a spoon of salsa or a drizzle of olive oil. That single cup mix lands near 15 g of protein and feels satisfying without a huge calorie load.
Tacos, Burritos, And Wraps
For wraps, 50–75 g of beans per tortilla works well. Two wraps built that way give around 9–13 g of bean protein before you count cheese, meat, or tofu. If you like a higher protein target, swap part of the rice filling for extra beans or add a second legume such as lentils.
Soups, Stews, And Chili
In soups and stews the beans hide in plain sight. A pot that uses 300–400 g of cooked black beans along with vegetables, tomatoes, and stock can serve four people. Each bowl carries roughly 7–9 g of bean protein, and toppings such as yogurt, grated cheese, or extra seeds can nudge that higher.
Black Beans, Calories, And Weight Goals
Because 100 g of cooked black beans bring just over 130 calories along with close to 9 g of protein and almost 9 g of fiber, they fit both muscle gain and fat loss plans. For people who like plant heavy plates, replacing some refined starch with beans keeps meals filling while holding calories steady or even slightly lower.
If you need to watch carbs, you can still use beans; just keep an eye on portion sizes and pair them with plenty of non starchy vegetables. Spreading bean servings across a few meals instead of loading them into one giant dinner often feels easier on blood sugar and digestion.
Final Protein Takeaways For Black Beans
One last time, here is the simple anchor number: 100 g of cooked black beans give about 8.9 g of protein along with a strong dose of fiber and minerals. That single scoop can make a real difference across a day, especially once you scale it up across bowls, wraps, and stews.
If you already enjoy beans, this number lets you tighten up macro tracking without turning meals into math class. If you are still getting used to them, try small 50–75 g portions at first, note how full you feel, and adjust from there. Either way, black beans remain one of the most practical plant proteins you can keep in the pantry.
