Health Benefits

- Supports Bone Health: Green beans are a good source of vitamin K, calcium, and manganese, all of which are essential for maintaining strong bones and preventing osteoporosis.
- Improves Eye Health: The vitamin A in green beans, primarily in the form of beta-carotene, supports vision and may help prevent age-related eye disorders such as macular degeneration.
- Anti-inflammatory and Antioxidant Properties: The flavonoids and other phytonutrients in green beans have potent antioxidant and anti-inflammatory effects. These compounds help neutralize free radicals, reducing oxidative stress and inflammation, which are linked to chronic diseases like cancer and heart disease.
- Aids in Pregnancy: Green beans are an excellent source of folate, which is essential for the proper development of the fetal brain and spinal cord. Adequate folate intake can help prevent neural tube defects during pregnancy.
