The Many Health Benefits of Nutritious Green Beans

The Many Health Benefits of Green Beans

Green beans are a familiar vegetable that most people have tried at some point. But did you know that these crunchy green pods are packed with nutrients and provide a wide range of health benefits? Here's an in-depth look at why you should be eating more green beans.

Nutrition Profile of Green Beans

One cup of raw green beans (about 33 grams) contains approximately:

• Calories: 31
• Carbs: 7 grams
• Fiber: 3 grams
• Protein: 1 gram
• Vitamin C: 14% of the RDI
• Vitamin K: 33% of the RDI
• Folate: 9% of the RDI
• Manganese: 12% of the RDI

Green beans are very low in calories and carbs. They also provide decent amounts of fiber, vitamins K and C, folate and manganese.

1. Support Bone Health

Green beans are a good source of vitamin K, with one cup providing 33% of the recommended daily intake (RDI). Vitamin K plays an essential role in blood clotting and bone metabolism.

Several studies have linked adequate vitamin K consumption with a reduced risk of bone fractures in older adults. Vitamin K is needed to activate osteocalcin, a protein involved in bone mineralization.

In fact, people who eat more green beans tend to have a higher bone mineral density and reduced risk of osteoporosis.

2. Boost Immunity

Green beans contain decent amounts of immune-boosting antioxidants and nutrients.

For example, vitamin C plays a central role in the immune system. Just one cup of green beans provides 14% of your daily needs for this antioxidant.

Green beans are also rich in antioxidants like carotenoids and flavonoids, which help reduce inflammation and may lower the risk of certain cancers.

Some of the antioxidants in green beans have been shown to decrease markers of oxidative stress in both animal and human studies.

3. Promote Heart Health

Consuming a variety of fruits and vegetables is linked to a reduced risk of heart disease. Green beans are no exception.

This is likely due to their content of important micronutrients that support heart health, including vitamin K, potassium, and choline.

One study found that leafy green vegetables, including green beans, may help prevent calcified plaque buildup in the arteries.

The fiber and antioxidants in green beans may also lower LDL (bad) cholesterol and reduce inflammation, further decreasing heart disease risk.

4. Aid Digestion

Some of the nutrients in green beans may help support better digestion.

For example, fiber plays an important role in digestive health. It adds bulk to stool and helps food pass more quickly through the gut, relieving constipation.

Soluble fiber feeds the beneficial bacteria in the intestines, which assists with digestion. Meanwhile, insoluble fiber prevents digestive issues like diverticulitis.

With 3 grams of fiber in just one cup, green beans may help support regularity and keep your digestive system healthy.

5. Help Control Blood Sugar

The fiber and nutrients in green beans help regulate blood sugar levels.

Fiber slows the digestion and breakdown of carbs. This results in a slower rise in blood sugar after eating a carb-containing meal.

Additionally, green beans have a low glycemic index, meaning they don't significantly impact blood sugar levels.

Studies show that low glycemic foods like green beans can promote blood sugar control in both healthy people and those with diabetes.

Adverse Effects

Green beans are highly nutritious and associated with many health benefits. They come with minimal risks and are safe for most people in normal food amounts.

However, some people may need to limit their intake.

Kidney Stones

Green beans contain oxalates, which can contribute to kidney stone development in susceptible individuals.

People who frequently develop kidney stones may need to limit foods high in soluble oxalate, including green beans.

Allergies

Green beans belong to the same family as soy, peanuts, and other legumes. People with existing allergies to these foods may react to green beans.

In young children, green bean allergy can cause irritation around the mouth, vomiting, diarrhea, and other symptoms.

Adults may experience hives, itching, swelling, wheezing, abdominal pain, and throat tightening after consuming green beans.

Medication Interactions

Green beans contain vitamin K, which can interfere with blood thinners like warfarin. People on these medications may need to limit vitamin-K-rich foods like green beans.

It's also important to check with your healthcare provider for other potential medication interactions with green beans.
