Wax beans, also known as yellow beans, are a vibrant and versatile vegetable closely related to common green beans. They are a cultivar of Phaseolus vulgaris, similar in structure, texture, and flavor to green beans. The primary distinction lies in their characteristic yellow hue, which results from a natural absence of chlorophyll. These beans offer a mild, slightly sweet taste and a tender, crisp texture, suitable for diverse culinary preparations.

Wax beans are a nutrient-dense food, providing various vitamins and minerals while remaining low in calories. A 1-cup serving, approximately 236 grams, contains around 68 calories, 5.6 grams of protein, and 16.7 grams of carbohydrates, including about 8.3 grams of dietary fiber. They are low in fat and cholesterol.
A 1-cup serving offers about 15-16.3 milligrams of Vitamin C. They also contain Vitamin K. In terms of minerals, wax beans provide iron (around 0.72-1.4 mg per serving), potassium (180-583 mg), and calcium (40-111 mg).

Health Advantages of Wax Beans
The rich nutritional profile of wax beans translates into several health advantages. Their significant fiber content supports digestive health by aiding in regular bowel movements and helping to regulate blood sugar levels. This dietary fiber contributes to heart health by helping to lower LDL (bad) cholesterol levels, reducing cardiovascular disease risk.
Potassium in wax beans assists in blood pressure regulation. The Vitamin C acts as an antioxidant, protecting cells from oxidative damage and supporting immune function. This antioxidant property also plays a role in wound healing and maintaining the strength of connective tissues, including bones.
Vitamin K supports bone health and blood clotting. The iron and manganese content in wax beans helps activate enzymes essential for energy production and metabolism. Iron supports red blood cell function, while manganese contributes to hormone production and connective tissue formation.
Adding Wax Beans to Your Meals
Incorporating wax beans into daily meals is straightforward due to their versatility and ease of preparation. They can be prepared using various cooking methods, including steaming, sautéing, or roasting. For instance, they can be quickly blanched and then sautéed with garlic and herbs for a side dish.
Wax beans add to salads, stir-fries, and casseroles, offering a tender crunch. They can be used interchangeably with green beans in most recipes, providing the same nutritional benefits and texture. Trimming the ends before cooking is recommended for best texture.
