2. Microgreens
Microgreens are immature greens produced from the seeds of vegetables and herbs. They typically measure 1–3 inches (2.5–7.5 cm).
Since the 1980s, they have often been used as a garnish or decoration, but they have many more uses.

6. Beet Greens
Since the Middle Ages, beets have been claimed to be beneficial for health.
Indeed, they have an impressive nutrient profile, but while beets are commonly used in dishes, the leaves are often ignored.
This is unfortunate, considering that they’re edible and rich in potassium, calcium, riboflavin, fiber and vitamins A and K. Just one cup (144 grams) of cooked beet greens contains 220% of the DV for vitamin A, 37% of the DV for potassium and 17% of the DV for fiber .

Swiss chard also contains a unique flavonoid called syringic acid — a compound that may be beneficial for lowering blood sugar levels .
In two small studies in rats with diabetes, oral administration of syringic acid for 30 days improved blood sugar levels .
However, it’s important to note that these were minor animal studies and that human research supporting the claim that syringic acid may aid blood sugar control is lacking.
While many people typically throw away the stems of the Swiss chard plant, they’re crunchy and highly nutritious.
Next time, try adding all parts of the Swiss chard plant to dishes such as soups, tacos or casseroles.

17. Green Onion
Green onions make it easy to cook healthy because they offer powerful savory flavor for virtually no calories. A whole cup of chopped green onions — more than you'd probably use in a single serving — still has just 19 calories, or less than 1 percent of your daily calorie limit if you're on a 2,000-calorie diet. And because those 19 calories come with a gram of dietary fiber and 66 grams of water, green onions are surprisingly filling — a definite benefit when you're trying to stick to a calorie-controlled diet.
When it comes to nutrients, green onions ace their vitamin A. Each cup of green onions has 2,840 IU of vitamin A, which covers the entire daily vitamin A needs for women and nearly 95 percent of the needs for men. And even smaller serving, like a tablespoon, supplies up to 10 percent of your vitamin A needs. Your body uses vitamin A for proper vision, and relies on vitamin A to create new blood cells — including the white blood cells required for immunity.
18. Mint
