Macronutrient Breakdown of Cooked Green Beans
Cooked green beans provide a beneficial balance of macronutrients for healthy eating. The composition is primarily carbohydrate-based, but with a significant portion of dietary fiber, minimal sugar, and a decent amount of protein for a non-starchy vegetable.
Calories
Per 100 grams, cooked green beans typically contain between 31 and 35 calories, depending on the cooking method and any added ingredients. This makes them a great option for weight management, as you can consume a large volume of food for a small number of calories, promoting a feeling of fullness.
Carbohydrates
A 100-gram serving delivers approximately 7-8 grams of carbohydrates. This carbohydrate content is comprised of dietary fiber and natural sugars, which results in a low glycemic index and load, preventing rapid blood sugar spikes.
Protein and Fat
While not a significant source of protein, cooked green beans provide about 1.8 to 2.1 grams per 100-gram portion. This complements other protein sources in a meal. The fat content is exceptionally low, usually ranging from 0.1 to 0.3 grams, and is primarily composed of beneficial polyunsaturated fats.
Rich Source of Dietary Fiber
One of the most notable features of cooked green beans is their high dietary fiber content, providing around 3.1 to 3.4 grams per 100 grams. This fiber is crucial for several aspects of health:
- Digestive Health: It promotes regular bowel movements and helps prevent constipation.
- Satiety: The fiber content helps you feel full and satisfied for longer, aiding in appetite control.
- Blood Sugar Management: Fiber slows the absorption of sugar into the bloodstream, which is particularly beneficial for managing diabetes.
Abundant Vitamins and Minerals
Cooked green beans are packed with essential vitamins and minerals that support various bodily functions.
Vitamins
- Vitamin K: Important for blood clotting and bone health, a 100g serving can provide a significant portion of the daily recommended intake.
- Vitamin C: A powerful antioxidant that supports immune function, boosts collagen production, and helps the body absorb iron.
- Vitamin A: Rich in beta-carotene, which the body converts to vitamin A, green beans support healthy vision and immune function.
- B Vitamins: They contain B vitamins like folate (B9), which is crucial for cell growth and metabolism.
Minerals
- Potassium: Essential for maintaining healthy blood pressure and nerve function.
- Manganese: Plays a role in metabolism, bone formation, and reducing inflammation.
- Calcium: Supports bone health and nerve signaling.
- Iron: Necessary for oxygen transport in the blood.
Comparison of Preparation Methods
The way green beans are prepared can affect their final nutritional content, particularly regarding sodium levels. This table compares the approximate nutritional values of different 100-gram preparations.
| Nutrient | Cooked (Boiled/Steamed, No Salt) | Canned (with Salt) | Frozen (Prepared Plain) |
|---|---|---|---|
| Calories | ~35 kcal | ~25 kcal | ~31 kcal |
| Protein | ~2g | ~1.3g | ~1.8g |
| Carbohydrates | ~8g | ~4.6g | ~7g |
| Fiber | ~3g | ~2.5g | ~2.7g |
| Sodium | ~1mg | >300mg | ~6mg |
Note: Nutrient values vary between brands and preparation specifics. Rinsing canned green beans can reduce the sodium significantly.
The Health-Boosting Properties of Green Beans
Beyond their nutritional figures, green beans offer several compelling health benefits thanks to their overall composition.
- Antioxidant Power: They contain phenolic compounds, flavonoids, and chlorophyll, which act as powerful antioxidants to fight free radical damage and reduce inflammation.
- Potential Anti-Cancer Effects: Some research indicates that the antioxidants and fiber in green beans may help slow the development of certain cancerous tumors.
- Support for Healthy Heart: With virtually no fat, low calories, and a healthy dose of fiber and potassium, green beans support cardiovascular health by helping to manage cholesterol and blood pressure levels.
- Aids in Weight Management: Their low-calorie and high-fiber combination make them a satisfying addition to meals, which can help prevent overeating and promote a healthy weight.
To maximize the health benefits, choose fresh or frozen plain green beans and cook them with minimal added fats and no salt. Steaming is an excellent cooking method for preserving nutrients.
