The string beans (also known as green beans) originated in Peru over 8,000 years ago and have now become one of the most widely planted and popular vegetables in the world. Not only are string beans healthy, but the dishes cooked with them are so delicious that they are highly favored by nutrition experts.
Personalized Nutrition writer and registered dietitian Katherine Tallmadge wrote in USA Today that string beans, despite being small, are versatile and always complement other foods without stealing the spotlight. She also mentioned that this vegetable, loved even by children, is easy to grow and has a longer market season compared to many other vegetables, making it more abundant and affordable.
According to data from the US Department of Agriculture, a cup of string beans contains calcium, iron, magnesium, potassium, phosphorus, sodium, zinc, folate, vitamin A, vitamin B6, vitamin K, and nearly 2 grams of protein. These nutrients help strengthen bones and muscles, lower blood pressure, promote immune system health, and even aid in relieving depression.
Tallmadge further explained that string beans are one of the highest-fiber vegetables, with “2.7 grams of fiber in a cup of raw string beans, containing only 31 calories,” which is beneficial for digestive health.
Jill Weisenberger, a registered dietitian in Virginia and author of “Prediabetes: A Complete Guide,” stated that like other non-starchy vegetables, string beans are filling, low in calories and carbohydrates, making them ideal for individuals needing to control weight or blood sugar levels.
Tallmadge pointed out that string beans contain 72 different plant nutrients, which effectively alleviate oxidative stress and inflammation, while actively combating unstable free radicals that may damage cells.
No matter how you enjoy string beans, there is no fear of overeating. Additionally, this versatile vegetable can be prepared in various ways such as stir-frying, sautéing, roasting, stewing, frying, steaming, and more, making it a delicious and never-tiring option.
Therefore, Weisenberger recommends “eating string beans and other non-starchy vegetables generously, filling half of your plate with them.” She emphasized, “They are extremely beneficial for your health.”
