The Core Question: Do Peas Have More Protein Than Green Beans?
When it comes to the head-to-head comparison of protein content, green peas are the clear winner. This is due to their classification as a legume, placing them in the same nutritional family as lentils and chickpeas. Green beans, while part of the legume family, are botanically classified as a fruit and consumed as a vegetable, with a nutritional profile closer to other non-starchy vegetables.
Protein Content Breakdown
To put the numbers into perspective, let's look at the protein content per 100-gram serving for both vegetables, based on standard cooking methods.
- Green Peas (cooked): A 100-gram serving of cooked green peas contains around 5.4 grams of protein. This makes them a decent plant-based protein source, especially for those following a vegetarian or vegan diet.
- Green Beans (cooked): In contrast, a 100-gram serving of cooked green beans offers only about 1.8 grams of protein. While still beneficial, they are not a significant source of this macronutrient.
A Closer Look at Pea Nutrition
Beyond their superior protein content, peas are nutritional powerhouses. They are an excellent source of dietary fiber, which aids in digestion and helps regulate blood sugar levels. Peas also provide a healthy dose of various vitamins and minerals, including Vitamin K, Vitamin C, manganese, and several B vitamins, such as folate. Their high fiber and protein content contribute to a feeling of fullness, which can be beneficial for weight management.
The Nutritional Profile of Green Beans
While lower in protein, green beans bring a lot to the table in other nutritional departments. They are packed with antioxidants, including flavonoids and carotenoids, which help fight cell damage. Green beans are also an exceptional source of Vitamin K, essential for blood clotting and bone health. Additionally, they provide a good amount of Vitamin C and Vitamin A. Their low-calorie and high-fiber nature makes them a great addition to any diet, especially for those looking to increase their vegetable intake without adding many calories.
Beyond Protein: A Full Nutritional Comparison
Choosing between peas and green beans isn't just about protein. The best choice depends on what other nutrients you're aiming to incorporate into your diet. For instance, if you're prioritizing fiber and a broader range of micronutrients, green beans might be a better choice for a specific meal, while peas can serve as a protein-rich component.
Fiber and Digestive Health
Both vegetables are high in dietary fiber, but there are differences. Green peas contain about 5 grams of fiber per 100 grams, while green beans have around 3.2 grams. For those focusing on digestive health or aiming to increase their fiber intake, peas have a slight advantage.
Micronutrient Differences
- Vitamin K: Green beans are a standout source of Vitamin K. While peas also contain this vitamin, green beans generally offer more. Vitamin K plays a vital role in bone metabolism and blood coagulation.
- Vitamin C: Both are good sources of Vitamin C, a powerful antioxidant. The specific amounts can vary based on freshness and preparation, but both contribute to your daily needs.
- Iron: Green peas contain more iron than green beans, which is beneficial for preventing anemia and supporting energy levels.
Comparison Table: Peas vs. Green Beans
| Nutrient (per 100g, cooked) | Green Peas | Green Beans |

| Folate | ~65 mcg | ~33 mcg |
Choosing the Right Vegetable for Your Goals
Deciding which vegetable to prioritize depends on your dietary objectives. For individuals looking to boost their protein intake, especially those on a plant-based diet, incorporating peas is a strategic move. They can be added to soups, stews, and side dishes to easily increase your protein count. Green beans, on the other hand, are an excellent option for those focusing on low-calorie, high-volume foods that provide essential vitamins and minerals. They are perfect as a side dish or in salads to add crunch and nutrient density.
How to Incorporate More Peas into Your Diet

Conclusion: The Final Verdict
The answer to the question, "Do peas have more protein than green beans?" is a definitive yes. However, this simple fact doesn't make peas inherently superior. Both vegetables offer valuable nutritional benefits and can be part of a healthy diet. Peas provide a more substantial protein and fiber boost, while green beans excel in delivering certain vitamins and antioxidants with fewer calories. By understanding the distinct nutritional profiles of each, you can make informed decisions to best support your health goals.
