Lettuce is divided into Romaine Lettuce, Boston Lettuce, Iceberg lettuce, Chicory, etc., according to the shape of the leaves. The most common one is iceberg lettuce. Lettuce contains four essential nutrients and their functions necessary for the human body.

1. Vitamin K

There are about 29 micrograms of vitamin K in every 100 grams of head lettuce. Vitamin K promotes blood clotting, helps heal wounds, prevents heavy bleeding. It plays a crucial role in maintaining bone density to avoid fractures, inhibiting arteriosclerosis, and regulating cell growth.

In addition, a 2020 study in the Netherlands showed that vitamin K-deficient COVID-19 patients might be more severely affected than average patients, leading to vitamin K’s recent attention.

2. B vitamins, folic acid

Lettuce also contains various other vitamins necessary for the human body, such as beta-carotene, vitamin E, vitamin B1, B2, B6 and niacin, etc. It also contains folic acid called “hematopoietic vitamin”, which is 73 micrograms per 100 grams.

3. Potassium

Ball lettuce contains a variety of trace elements necessary for the human body. The potassium content is the most, and every 100 grams of ball lettuce includes 200 mg of potassium. Potassium can help the body excrete sodium, maintain the heart muscle and nervous system, and play an essential role in regulating the body’s acidity and alkalinity.

4. Dietary fibre

Every 100 grams of head lettuce contains 1.1 grams of dietary fibre. Dietary fibre, also known as the “sixth nutrient”, can stimulate large intestine motility. It also relieves constipation, slow down the absorption of carbohydrates, and inhibit the rise of postprandial blood sugar.

How to eat lettuce: eat with oil to absorb nutrients more easily

One way to save lettuce: no discolouration, fresh and crisp taste, no astringency
Lettuce bulbs are easy to change colour. Even if they are kept in the refrigerator, the leaves will gradually turn yellow. Especially the bulb roots tend to turn red due to the oxidation of chlorophyll, so it is best to eat them as soon as possible.

If you buy too much lettuce to eat in time, you can store it in the refrigerator. The key is to prevent the lettuce from drying, wrap it in damp kitchen paper, and put it in a breathable plastic bag.

There is another way to store it. After cutting the lettuce, soak it in warm water and put it in the refrigerator. It can be stored for at least three or four days without discolouration, and it can also retain nutrients to the greatest extent.

The dietary fibre contained in the lettuce is insoluble. The vitamins contained in it are primarily fat-soluble. The block lettuce preserved after soaking in warm water does not change colour, is rich in nutrients, and removes the astringency. Better taste.
