Salad greens are packed with important nutrients and phytochemicals that support the maximum benefit to our day to day vegetable requirement.
Antioxidants
- According to a recent study, plant-based foods contain antioxidants (polyphenols) that may improve blood sugar in people at risk for diabetes and heart diseases. Vegetables have abundant levels of antioxidants that prevent cardiovascular problems and the growth of cancerous cells. Moreover, antioxidants boost immunity and prevent infections and diseases.
- Most of the green, yellow, and orange vegetables also have a high percentage of calcium, potassium, iron, magnesium, vitamin B-complex, vitamin A, vitamin C, vitamin K, zeaxanthin, α and β carotenes, and crypto-xanthins.
- Dark green vegetables have lots of phenolic flavonoid antioxidants and minerals. Leafy green vegetables have a bioflavonoid known as ‘quercetin’. It has antioxidant, anti-inflammatory, and anticancer properties. Quercetin also effectively cuts down the flow of substances that lead to allergies. This compound plays the role of an inhibitor of mass cell secretion, thereby decreasing the release of interleukin-6.
Dietary Fiber
- Vegetables are abundant in soluble as well as insoluble dietary fiber, known as non-starch polysaccharides (NSP). This dietary fiber absorbs the extra water in your colon and thereby retains the moisture content in the fecal matter.
- Eating fiber-rich vegetables keep your digestive system clean and healthy, helping you avoid problems like constipation, diarrhea, bowel irregularity, colon cancer, and even polyps. Vegetables also aid in preventing hemorrhoids and rectal fissures.
