Leafy green vegetables are an essential component of a balanced diet.

They are high in fiber, minerals, and vitamins while being low in calories, but we should know which are the healthiest ones.

A diet abundant in leafy greens has been shown to lessen the risk of mental decline, obesity, and high blood pressure.

In this article, we will be looking at some of the best healthy leafy green vegetables which are good for you.

Here are some of the best healthy leafy green vegetables:

  1. Microgreens

    Immature greens made from the seeds of herbs and vegetables are known as microgreens.

    They are usually 2-4 inches in length. They have been employed as decoration or garnish since the 1970s.

    They have a lot of functions[2]. They are a combination of nutrients and flavor despite their small size.

    Microgreens contain up to 30 times more nutrients than their mature counterparts, according to one study.

    Vitamins K, C, and E are examples of these nutrients.

    Microgreens might be cultivated throughout the year in the comfort of your own home, making them readily available.

  2. Cabbage

    If you want to keep your blood glucose levels in check, cabbage might be a great option.

    It has a low-calorie count and contains a lot of fiber.

    Because of its antihyperglycemic and antioxidant characteristics, it could help[3] those with diabetes.

    Adding cabbage as a side dish at least once a day is a simple way to incorporate it into your diet.

    If you do not want to eat it as a side dish, you might receive the same advantages by adding it to soups, salads, and dals.

  3. Spinach

    Spinach is a common leafy green vegetable that could be used in a wide range of meals, such as salads, sauces, soups, and smoothies.

    One cup (35 grams) of raw spinach provides 15 percent of the daily value for manganese, 180 percent of the daily value for vitamin K, and 58 percent of the daily value for vitamin A.

    It is also high in folate, which aids in the prevention of neural tube abnormalities during pregnancy and the synthesis of red blood cells, according to research[4].

    Low folate consumption during the first trimester of pregnancy was revealed to be one of the most preventable risk factors for spina bifida, which is a neural tube defect in one study.

    Eating spinach, in addition to taking a prenatal vitamin, is an excellent method to boost your folate consumption during pregnancy.

  4. Watercress

    Watercress is a nutrient-dense[5] leafy green vegetable that is little but powerful.

    Watercress, such as cabbage, kale, and brussels sprouts belong to the Brassicaceae family of vegetables.

    The entire plant is edible and has a light peppery flavor which gets lighter when cooked. It has round small leaves and light, small stems.

    It is often found in sealed bags in the salad section of most supermarkets.

    Watercress is delicious in sandwiches, pasta dishes, salads, smoothies, and as a side of sauteed greens.

  5. Lettuce

    Lettuce is a popular leafy vegetable with a strong center rib and dark leaves.

    It is quite popular, especially in salads, because of its crunchy texture.

    It is high in vitamins K and A, with one cup (35 grams) supplying 65 percent and 85 percent of the daily value for these nutrients, respectively.

    Furthermore, studies in animals revealed that lettuce lowered[6] blood lipid levels, potentially lowering the risk of heart disease.

    More research into these benefits in people is needed.

  6. Mustard leaves

    The peppery leaves of the mustard plant, which is also known as Chinese mustard, Indian mustard, brown mustard, and vegetable mustard are one of the most nutritious greens you could consume.

    Mustard leaves and seeds are also edible, which makes them a year-round addition to your menu.

  7. Bok Choy

    Bok choy is Chinese cabbage. It has green dark leaves which work quite well in stir-fries and soups.

    Bok choy is high in selenium. It is a mineral that aids in cancer prevention, cognitive function, and immunity.

    Selenium is also necessary for normal thyroid gland function.

    This gland, which is located in your neck, produces hormones that are important for metabolism.

    Low selenium[7] levels were linked in observational research to thyroid disorders, such as enlarged thyroid, hypothyroidism, and autoimmune thyroiditis.

  8. Turnips

    The dark leafy green tops of turnip plants are known as turnip greens. These greens are cruciferous vegetables.

    It means they contain more phytonutrients[8] and minerals than the turnip itself.

    The greens are leafy and large, with a somewhat spicy flavor. It might be cooked and served in the same way as mustard greens.

    Turnip greens are a tasty alternative to traditional greens which might be sauteed, braised, or used in salads.

    One cup (35 grams) of raw kale contains 135 percent of the daily value for vitamin C, 685 percent of the daily value for vitamin K, and 208 percent of the daily value for vitamin A.

    It also contains antioxidants, such as beta-carotene and lutein, which help to minimize[9] the risk of oxidative stress-related disorders, according to a study.

    Kale is best consumed raw to get the most out of what it has to offer, as cooking might diminish its nutritious profile.

  10. Arugula

    Arugula, leafy green with a peppery flavor, is another leafy green vegetable that nutritionists usually prescribe.

    It is high in dietary nitrates, which help the body produce more nitric oxide.

    It is also high in antioxidants which help the anti-inflammatory compounds and immune system.

    The best way to eat this vegetable is minimally cooked or raw.

    While some individuals dislike the spicy flavor, some like it. The same could be said for its scent.

    If you are in the latter group, start with a small amount of arugula before adding more.

    You might even learn to enjoy its spicy flavor once you have gotten used to it.

    Nitric oxide is required for a variety of tasks, including the relaxation and dilation of blood vessels, which lowers[10] blood pressure.

  11. Swiss chard

    Swiss chard features a sturdy stalk and green dark leaves with a variety of benefits.

    It includes syringic acid, a rare flavonoid, as well as different beneficial elements[11].

    Swiss chard is a common ingredient in Mediterranean cuisine. When raw, the leaves have an earthy and bitter flavor.

    When cooked, they have a sweet and mild flavor akin to spinach.

    The stems of the Swiss chard plant are often discarded, though they are quite healthy.

    Collards are one of the efficient foods for improving your heart health as they contain folate, a B vitamin that is beneficial to a healthy heart.
