Green Beans Health Benefits


Green beans are a necessity in many families across the United States. Snap beans and string beans are two of the most common names for these beans. They are not usually green, as they have varieties that can also be yellow or purple.


Green beans are low in calories, but they are high in nutrients that provide a variety of health advantages. Vitamin C, quercetin, flavonols, and kaempferol are all antioxidants found in legumes. These antioxidants battle free radicals in the body, reducing cell damage and maybe lowering the risk of certain diseases.


Green beans also provide the following health benefits:


Improves Our Heart Health


Green beans are high in fiber, which is a beneficial food nutrient for various reasons. Soluble fiber has been shown to promote heart health by reducing LDL cholesterol (bad cholesterol).


Safeguards Gut Health


The fiber content from green beans can keep your digestive tract healthy and working smoothly. On the other hand, certain forms of fiber might cause gas, intestinal pain, and bloating if you have a digestive disease like irritable bowel syndrome.


Assist in a Healthy Pregnancy


Folate is a vitamin B essential for unborn infants’ growth and development. The vitamin aids in the prevention of several birth abnormalities. A single cup of green beans contains around one-third of your daily required folate consumption.


Keeps Our Bones Healthy


Green beans are rich in vitamin K and are a good calcium source. These nutrients are essential to keep strong, healthy bones and lower the risk of fractures.


Decreases Depression


Vitamin B is beneficial in preventing depression. Having enough folate helps to lower homocysteine levels in the body. 


Homocysteine deficiency can disrupt the normal production of serotonin, dopamine, and norepinephrine; these are the hormones that control your mood, sleep, and appetite.


Prevents Anemia


Iron is a necessary component of red blood cells, which transport oxygen from the lungs to all other cells in your body. Anemia occurs when the quantity of red blood cells or the amount of hemoglobin inside the cells is lower than usual. 


Green beans are a good source of iron from plants, which might help you receive the amount you need to avoid anemia.


Helps to Prevent Cancer


Green beans include chlorophyll, which may aid in the slowing of cancer tumor development and lowering cancer risk. However, animals are used in recent studies. More study is needed to validate chlorophyll’s anti-cancer properties.

Can You Roast Frozen Green Beans?


Yes, you use frozen green beans easily:


  • Let the frozen green beans set at room temperature, and take a paper towel or tissue to soak up the moisture or any liquid. Otherwise, they will be soggy and steam in the oven instead of roasting. 
  • Start roasting them at 450 degrees, a slightly high temperature, to cook them properly.

Is It Ideal to Bake or Boil Green Beans?


Both ways are amazing! Sometimes I love baking my green beans, dressing them with salt and butter. It is simple and yummiest! 


However, oven baking has its benefits, and I love this way of making vegetable crispy, especially when roasted with fresh garlic. 

Do I Need to Wash Green Beans Before Cooking?


Of course! I like to wash my vegetables before cooking. For this recipe, do make sure to dry the green beans thoroughly. You want the beans to roast perfectly in the oven, not turn them steamy. 


Why My Green Beans Taste Rubbery?


Undercooked green beans are rubbery, and overcooked ones are mushy. When you are baking them, simply start tasting them when they are ready. If you have a hard time biting them, then they are not properly roasted yet. 


Try them again after a few minutes; if you can bite through without any resistance, then they are perfectly cooked.  


What is Tamari Sauce?


Tamari sauce is a popular sauce used in most Japanese cuisine, also known as tamari shoyu. It has gained popularity worldwide because of its rich flavor; moreover, it’s vegan and gluten-free. 


If you compare tamari with soy sauces, then it has a darker, contains no wheat, and has a pleasant savory taste. Although some varieties of tamari have wheat, most of them are vegan, gluten-free, and wheat-free. 


Soy sauce mostly contains a high amount of wheat, making them unsuitable for people who do not want gluten in their diet. Furthermore, they are lighter in color and sweeter, which is why it’s ideal to use tamari sauce.      


Serving Suggestions


Serve the roasted green beans with light or healthy side dishes to hearty main meals. They could be worthy of showing off at your holiday table. I particularly love to enjoy roasted green beans with an Italian tomato-y dish, brown rice, etc.  



How to Store Roasted Green Beans?


  • Leftovers can stay fresh in the refrigerator in the airtight container for at least 3 to 4 days. Sometimes I like to have them cold. 
  • Properly stored cooked beans can stay of the best quality for 10 to 12 months. 
  • You can also reheat the beans in the air fryer or preheated oven covered for a few minutes. 

Pro tips and Tricks 


  • I have used a darker baking sheet to make the beans look a bit darker, but you can use lighter ones if you prefer them.
  • A squeeze of lime or lemon juice after roasting adds a hint of sour, fresh, and natural flavor. 
  • Never overcook the green beans! Keep an eye on the oven while cooking and remove any if they look cooked to your preference. 
  • Roasting green beans takes out lots of sugar from them, making them crispier. So don’t let them sit around once they are out of the oven, or you will lose the texture and flavors.
