Nutritional Breakdown: Peas vs. Green Beans
While both peas and green beans are healthy, plant-based foods, their nutritional profiles differ significantly. Understanding these differences can help you make an informed choice based on your specific dietary needs, whether you are managing weight, monitoring carbohydrate intake, or seeking specific micronutrients.
Macronutrient Profile: Protein, Fiber, and Calories
When comparing the macronutrient content per 100g serving, peas are denser than green beans, which contain more water. This density accounts for the major differences in calories, protein, and carbohydrates.
- Calories: A 100g serving of peas has approximately 84 calories, while green beans contain only about 35 calories. This makes green beans the clear winner for those on a low-calorie diet, although both are considered low-calorie foods overall.
- Protein: Peas offer a significant amount of plant-based protein, providing almost three times more than green beans (8.6g vs. 1.8g per cup). This makes peas a more substantial choice for promoting fullness and supporting muscle repair.
- Fiber: With 5.5g of dietary fiber per 100g, peas have about 1.7 times more fiber than green beans, which contain 3.2g. This higher fiber content in peas aids in digestion, promotes satiety, and helps regulate blood sugar.
- Carbohydrates: Peas contain a higher carbohydrate count, with green beans having 52% less total carbs than peas. This is a crucial distinction for those on low-carb diets.
Micronutrient Showdown: Vitamins and Minerals
Both legumes are rich in micronutrients, but they excel in different areas. Peas generally have a broader vitamin and mineral profile, while green beans contain higher levels of specific nutrients.
Peas are higher in:
- B Vitamins: Peas are an excellent source of most B-group vitamins, including significantly higher amounts of B1, B3, B5, B6, and B9 (folate).
- Minerals: They contain higher levels of essential minerals like zinc, phosphorus, iron, potassium, magnesium, and manganese.
- Vitamin A: Peas offer more Vitamin A, which supports eye health.
Green beans are higher in:
- Vitamins K and E: Green beans contain significantly more Vitamin K and Vitamin E compared to peas. Vitamin K is crucial for bone health and blood clotting.
- Calcium: Green beans provide a higher amount of calcium, another vital mineral for strong bones.
- Antioxidants: Both contain antioxidants, but green beans offer a range of flavonols, including quercetin and kaemferol.
Health Implications: Making the Right Choice
Your ultimate choice should align with your health goals and sensitivities. For most people, a diet rich in both vegetables provides a wider range of nutrients, but specific situations may favor one over the other.
- For weight management: Green beans, with fewer calories and carbohydrates, are often preferred for low-calorie or keto-style diets. However, the higher protein and fiber content in peas can increase satiety, helping to manage hunger.
- For digestive health: Individuals with irritable bowel syndrome (IBS) or other functional bowel disorders may tolerate green beans better. Green beans are low in FODMAPs, which can cause discomfort in some people, while peas are higher in fermentable oligosaccharides that can lead to bloating.
- For blood sugar control: Both are good choices due to their low glycemic index, but green beans have a slightly lower GI value (36 vs. 54 for peas). The fiber and protein in peas, however, help regulate blood sugar levels more effectively by slowing carbohydrate absorption.

Versatility in Your Diet
Both vegetables can be prepared in various ways, from steaming and sautéing to adding them to soups, stews, and salads. Opting for fresh or frozen varieties is generally the best way to preserve their nutritional integrity, as canned options can be high in sodium. For those concerned about lectins in raw green beans, cooking them thoroughly is recommended to deactivate these proteins.
Conclusion: Which is the winner?
There is no single “winner” in the peas versus green beans debate, as the healthier choice depends on individual health goals. Peas pack a more nutrient-dense punch with higher protein, fiber, and many B vitamins, making them excellent for building muscle and promoting satiety. In contrast, green beans are significantly lower in calories and carbs, making them ideal for weight-loss diets or those following low-FODMAP plans. Both are loaded with beneficial vitamins, minerals, and antioxidants that contribute to a healthy diet. The best strategy is to enjoy both legumes, incorporating them into a varied and balanced eating plan to reap the diverse benefits of each.
