Stubborn weeds in the wheat field

The noodle vegetable got this down-to-earth name in Henan and other places because its young leaves are smooth and resemble noodles when cooked.

Noodles are also called rice pots, and their scientific name is bottle grass. They belong to the genus Flywort of the Caryophyllaceae family. They have been "fishing in troubled waters" since wheat was sown - their seeds germinate in the wheat seeds, and their seedlings grow close to the ground in a gray-green rosette shape, with their own white fluff camouflage, making it almost "indistinguishable" from wheat seedlings . When wheat joints in spring, it also jumps to 30 cm in height, and spreads its fine sand-like seeds into the soil before harvesting, causing a lot of trouble for farmland management. Therefore, it is also a stubborn weed hidden in the wheat field.

This wild grass, which originated in the Yellow River Basin, is now widely distributed in major grain-producing areas across the country. From the wheat fields of Henan to the wasteland and grass slopes of Jiangsu and Shandong, from the dry land in the northwest to the black soil in the northeast, wherever crops are grown, you can always see it snatching nutrients and occupying land.

Why are noodles so tenacious? It all depends on three survival skills:

● The lantern-like structure of the flower can store morning dew as a source of water.

● The seeds have mucus on their surface, which can stick to farm machinery and animals and spread.

● Seeds underground can remain dormant for many years and only germinate when they encounter the right environment.

Thanks to these abilities, it has managed to survive in farmlands for thousands of years, becoming one of the most difficult weeds to remove.

However, this wild grass that causes headaches for farmers actually contains unexpected nutritional value.

What’s special about nutrition?

Like green leafy vegetables, pasta is low in calories and high in fiber. In addition to this advantage, pasta is a treasure trove of nutrients.

1

Vitamin C

According to the data of the Chinese Food Composition Table (Standard Edition), every 100 grams of fresh noodles contains 49 mg of vitamin C, which is nearly 50% higher than oranges (33 mg/100 grams). In simple terms, if you don’t consider the loss during cooking, eating a handful of noodles (about 200 grams) can meet the vitamin C needs of an adult for the whole day.

High temperature and short cooking time can reduce the loss of vitamin C. It is good to mix it with cold food after blanching. It is even better to add a few drops of vinegar when mixing it with cold food, because the acidic environment is conducive to the preservation of vitamin C.

2

Minerals

The calcium content of noodles is 153 mg/100 g, which is 1.5 times that of pure milk (107 mg/100 g). However, because it is a plant-based source, the absorption rate is lower than that of milk. It is recommended to pair it with ingredients that are relatively high in vitamin D (such as mushrooms and egg yolks) to make the calcium supplementation effect more effective.

In addition to calcium, the iron content of celery is also high among plants. It contains 4.5 mg of iron per 100 g. Compared with spinach (2.9 mg iron/100 g), the iron content of celery is 1.6 times that of spinach, making it one of the few vegetables that are good at supplementing iron. Combined with its own vitamin C, it can increase the absorption rate of non-heme iron in plants.

3

Antioxidant ingredients

The carotene content of noodles is 4160 micrograms/100 grams, which is equivalent to the content of 500 grams of mango, slightly better than carrots (4107 micrograms). Carotene not only has an antioxidant effect, but can also be converted into vitamin A in the body. Adding vegetable oil to mix with blanching can increase the absorption rate of carotene.

In addition to carotene, antioxidant flavonoids are also very rich. Wang Shuangxi and other scholars found that glutathione extracted from noodles has good in vitro antioxidant activity; Liu Meiyan and others' experiments also verified that among the common wild vegetables in northern Jiangsu, the SOD activity of noodles (miwa jar) is much higher than that of the other four wild vegetables.

How to eat more safely?

If you want to eat it, it is recommended to buy it from reliable channels, such as farmers' markets, supermarkets or online shopping platforms. These channels usually conduct regular inspections to ensure the safety of the ingredients. Some online shopping platforms also provide quality inspection reports to make consumers feel more assured when eating.

When purchasing, be sure to choose noodles with bright green leaves, no yellow spots, and no insect bites , to avoid buying contaminated or spoiled products.

If you insist on picking them yourself, you need to pay special attention to two points:

● First, the site should be far away from pollution sources. Wild vegetables close to roads are easily polluted by automobile exhaust, which can easily lead to excessive lead and cadmium levels;

● The second is to identify the plants accurately. If you don’t often pick wild vegetables, it is very easy to get confused. It is recommended that you don’t pick them to avoid picking plants that look similar but are poisonous.

The surface of the greens just picked from the wild may be clinging to some dirt, impurities, and pesticide residues. Before eating, be sure to clean the greens. You can rinse them with running water for 30 seconds with the leaves facing down to remove surface mud and reduce residual impurities.
