韭菜: 營養,健康的益處和烹飪

Chives, also known as shrimp scallions, leeks, and scientifically known as Allium schoenoprasum, are part of the Allium genus, which also includes garlic, onions, and leeks. It is a versatile and delicious herb. These slender, grass-like herbs have been cultivated for centuries for their characteristic pungent flavor in cooking and medicinal properties. Native to Europe, Asia, and North America, it is widely cultivated for its culinary and medicinal uses.

appearance

Chives are characterized by long, hollow stems that resemble thin blades of grass. The stems grow in clumps, reaching a height of 12 to 24 inches. In summer, chives produce delicate, spherical flowers, usually pink or purple.

Flavor Profile

Chives have a mild onion flavor with a hint of garlic. Leeks are less pungent in flavor than onions or garlic, making them a popular choice for adding a delicate onion flavor to dishes without overpowering other flavors.

culinary use

Chives are highly valued in culinary applications for their fresh herbaceous flavor and vibrant green color. They are often served as a side dish, adding color and flavor to dishes such as soups, salads, omelets, and baked potatoes. Chives can also be chopped and added to sauces, dips, dressings and spreads to add flavor.

nutritional value

Leeks are low in calories but rich in essential nutrients. They are an excellent source of vitamins A and K, as well as folate and antioxidants. Leeks also contain small amounts of minerals such as calcium, magnesium and potassium. Additionally, they are rich in beneficial plant compounds, such as flavonoids and sulfur compounds, which have been linked to various health benefits.

That is, to get a lot of these nutrients, a person must eat a lot of leeks. Instead, people often use leeks as a garnish. A common serving size is about 1 tablespoon, or 3 grams.

According to the United States Department of Agriculture (USDA)Trusted Source, 1 tablespoon of chopped leeks provides the following nutrients:

  • Energy: 0.9 calories
  • Vitamin K: 6.38 micrograms (mcg), or 5% of the Daily Value (DV)
  • Vitamin C: 1.74 milligrams (mg), or 2% of the DV
  • Folic acid: 3.15 mcg, or 1% of daily value
  • Vitamin A: 6.43 mcg, or 1% of daily value
  • Calcium: 2.76 mg, or less than 1% of daily value
  • Potassium: 8.88 mg, or less than 1% of daily value

health benefits

Antioxidant properties

Chives contain antioxidants that help protect cells from damage caused by free radicals, potentially reducing the risk of chronic disease.

Anti-inflammatory effect

Some research suggests that leeks may have anti-inflammatory properties, helping to reduce inflammation in the body and reduce the risk of certain diseases. Although no studies link leeks to inflammation, a 2015 study reported that garlic can reduce inflammation in the body. Inflammation is linked to a variety of health conditions, including heart disease and several types of cancer.

digestive health

The fiber and prebiotics in leeks can promote digestive health by supporting the growth of beneficial gut bacteria and improving intestinal regularity.

cancer

Research has found a link between a diet rich in vegetables and a lower risk of cancer. Specifically, allium vegetables such as leeks may have anti-cancer properties. A 2019 review highlighted that certain compounds in allium vegetables may help prevent or positively impact cancer. Another study showed that garlic and leeks may reduce the risk of breast cancer, but large amounts of cooked onions may increase the risk. Due to their sulfur compounds and antimicrobial effects, allium vegetables may also reduce the risk of gastrointestinal cancer. However, more research is needed on the specific effects of leeks.

sleep and mood

Leeks contain small amounts of choline, an important nutrient for cell membranes, mood, memory and nervous system function. The recommended intake is 550 mg/day for men and 425 mg/day for women. One tablespoon of leeks provides 0.16 mg of choline.

Source of Vitamin K

Chives contain vitamin K, which is important for bone health and blood clotting. Other sources of vitamin K include green leafy vegetables, vegetable oils, and fruits such as blueberries and figs.

Sources of folic acid

Leeks also contain folic acid. According to ODSTTrusted Source, this water-soluble B-complex vitamin plays a role in:

  • Dementia, including Alzheimer's disease
  • cancer
  • congenital heart defects
  • Cognitive function
  • Cardiovascular disease and stroke
  • frustrated
  • premature birth

eye health

Leeks also contain lutein and zeaxanthin, which are carotenoids. According to some studies, lutein and zeaxanthin accumulate in the retina of the eye and help prevent age-related macular degeneration. This means that eating foods rich in these substances may benefit vision.

Dietary considerations

Leeks are not a common source of food allergies, but people with allergies or intolerances to onions or other allium vegetables may also need to avoid leeks. People with food allergies may want to talk to their doctor before adding leeks to their diet. Additionally, some people may find that eating large amounts of leeks can cause an upset stomach. However, most people can safely add leeks to their diet as long as they are in moderation.

cooking tips

  • Use fresh chives as a garnish for salads, soups and savory dishes.
  • Add chopped chives to scrambled eggs, omelettes, or frittatas for added flavor.
  • Mix chopped chives with softened cream or cream cheese to make a delicious spread for bread or cookies.
  • Freeze chopped chives in ice cube trays with water or olive oil for easy use in cooking.
  • All in all, chives are a versatile and delicious herb that add color to a variety of dishes with their mild onion flavor and bright green color. Whether used as a garnish, condiment or ingredient, chives are a delicious and nutritious addition to any cooking.
