Frequently Asked Questions (FAQ)
How many calories are in a cup of green beans?
One cup of raw green beans (about 100 grams) contains approximately 31 calories. Cooked green beans have slightly more calories per cup at about 44 calories because they shrink during cooking, packing more weight into the same cup. Both servings are very low-calorie and provide a solid amount of fiber and vitamins.
Are green beans good for weight loss?
Green beans are an excellent choice for weight loss. They are very low in calories, high in fiber, and have a high water content, all of which help keep you feeling full without adding significant calories. One cup provides only 31 calories while delivering 3.4 grams of satisfying fiber.
Are green beans a good source of protein?
Green beans contain a modest amount of protein for a vegetable — about 1.8 grams per cup raw. While they are not a primary protein source, they contribute to your daily protein intake when combined with other foods. Green beans pair well with protein-rich foods like almonds, chicken, or tofu for a balanced meal.
Are canned green beans as nutritious as fresh?
Canned green beans retain most of their macronutrients and are still a healthy choice. However, they typically have slightly less vitamin C and folate than fresh or frozen varieties due to heat processing. Canned green beans may also contain added sodium, so choosing low-sodium versions or rinsing them before eating can help reduce sodium intake.
Do green beans have a lot of vitamin K?
Yes. One cup of raw green beans provides about 43% of the daily recommended intake of vitamin K. Vitamin K is essential for proper blood clotting and plays an important role in bone metabolism. People taking blood-thinning medications should be mindful of their vitamin K intake and keep it consistent.
