Collard greens often have a negative reputation because they aren’t always prepared in the healthiest way. A lot of preparations involve bacon, ham hocks, turkey legs, and a lot of salt, and the greens are cooked down to a point where they have a lot less nutritional value. In truth, collard greens are very healthy, incredibly versatile, and exhibit some seriously impressive health benefits.
What Are Collard Greens?
Kids may not be the biggest fans of collard greens, but these nutritious leafy greens should be on your grocery list. Collards belong to the cruciferous vegetable family, which includes broccoli, cauliflower, Brussels sprouts, and bok choy. Just like other cruciferous vegetables, collards contain sulforaphane, which is a compound that helps to fight inflammation, balance hormones, and fight free radicals. Continue reading to learn more about the health benefits of collard greens.
They Contain A Lot Of Nutrients
Collards are nutrient-dense greens that contain a lot of vitamin A, with one cup providing over 300% of the recommended daily intake (RDI). They also provide B vitamins (particularly folate) and vitamin C, with one cup providing 50% of the RDI. Folate is the naturally occurring form of folic acid, and a cup of collards provides about 44% of the RDI of folate. Just like kale or Swiss chard, collard greens are an excellent source of vitamin K1, providing an impressive 1,045% of the RDI in one cup. Collards also offer other nutrients, including manganese, calcium, phosphorus, magnesium, and potassium.
They Exhibit Anti-Cancer Activity
As previously mentioned, collards provide a lot of vitamin A and vitamin C, both of which encourage a healthy immune system. Optimal immune response is essential for protecting the body foreign invaders and cancer. Research shows that collard greens contain glucosinolates and sulforaphane, both of which are subjects of cancer research. Scientists say that glucosinolates are converted into isothiocyanate (ITC), which protects cells from damage that can lead to cancer, particularly colon, oral, breast, and skin cancers. By increasing your consumption of leafy greens, you may help reduce your risk of cancer.
They Support Gut Health
Collards, just like other leafy greens, contain fiber, which works to optimize digestive health by promoting a healthy microbiome. Researchers note that fiber contributes to regularity, which helps you avoid constipation. Additionally, some studies have identified a unique sugar in leafy green vegetables (sulfoquinovose), which works to feed the good bacteria in your gut. That ultimately supports the digestive process.
They Have Anti-Inflammatory Properties
According to research, some of the compounds in collard greens may exhibit anti-inflammatory properties. For that reason, incorporating collards into your diet may help reduce the risk of arthritis and other inflammatory conditions. Collard greens also contain lutein, carotenoids, zeaxanthin, and other antioxidants that help reduce oxidative stress. Lowering the amount of oxidative stress in the body may help reduce inflammation, which may decrease the risk of certain health conditions.
They May Help People With Diabetes
As mentioned earlier, collards are rich in fiber, which helps regulate bowel movements and satiates you after a meal. Increasing your fiber intake has been associated with a lower risk of stroke and type 2 diabetes. The belief is that fiber reduces inflammation and levels of glucose in people with type 1 diabetes. Other research shows that fiber works to maintain healthy insulin and blood glucose levels in people with type 2 diabetes. More research is necessary to see how the fiber in collards directly benefits diabetic patients.
They May Improve Bone Health
The impressive amount of vitamin K1 in collard greens, in addition to the vitamin K2 in animal foods, is critical for healthy bones. The body requires vitamin K for calcium absorption, which reduces the risk of fractures. Because collard greens contain both calcium and vitamin K, adding them to your diet can help keep your bones healthy. For reference, the average vitamin K recommendation for adult males is 120 micrograms (mcg) per day and 90 mcg per day for adult women.
