We have an interesting phenomenon in the process of cooking. Some vegetables only eat the stems but not the leaves. Some vegetables only eat the leaves but not the sides. For example, when eating celery, we are used to eating the leaves. Throw it away, and it is customary to throw away the cabbage when eating cabbage. What's going on? Which parts of vegetables are the most nutritious?

Let’s list three common vegetables, celery, cabbage and sweet potato. Let’s take a look at which parts are more nutritious:

Which part is more nutritious, celery leaves or celery stems? ?

Celery is usually sold with the stems and leaves together when purchased, but people often choose to discard the celery leaves and only eat the celery stems. In the eyes of many people, celery stems are crisp, delicious and rich in dietary fiber, while celery leaves have a rough texture and are not very tasty.

But in fact, it is wrong to think that celery stems have more dietary fiber than celery leaves. The "Food Nutritional Composition Table" clearly shows that the dietary fiber in celery stems is 1.2g per 100g, and the dietary fiber in celery leaves is 1.2g. Fiber is 2.2g. In addition, the flavonoids, protein, vitamin C, B vitamins and other nutrients in celery leaves are higher than those in celery stems.

In addition, celery leaves are extremely rich in potassium. For people with high blood pressure, regular intake of potassium has a positive effect on the condition. It can be seen that the celery leaves you throw away have the highest nutritional value.

Which part of cabbage heart or cabbage gang is more nutritious?

Many people have the habit of eating cabbage raw. Choy sum is the tenderest part of the whole cabbage, and it tastes crisp, tender and juicy. In order to make their children eat more nutritiously, some mothers simply eat the cabbage leaves and cabbage gangs themselves and leave the cabbage hearts to their children.

But in fact, the most concentrated part of vitamins, minerals and other nutrients is the vegetable leaves, and the part with the most dietary fiber is the cabbage side. Compared with these two parts, the nutritional value of the cabbage heart is not high. Therefore, when choosing ingredients for your children, you must not choose based on taste.

Which part of sweet potato or sweet potato leaves is more nutritious?

Sweet potatoes are fragrant, glutinous and sweet, and are the most common root vegetables in the kitchen. Many people only know that sweet potatoes are delicious, but they do not know that sweet potato leaves have higher nutritional value. In the "Top Ten Fruits and Vegetables" list released by the Chinese Nutrition Society, sweet potato leaves are listed as the vegetables with the highest carotene content.

The carotene content in every 100g of sweet potato leaves is as high as 5968 μg, which is higher than the carotene content in carrots. People who often use their eyes often eat sweet potato leaves, which can help improve vision. In addition, patients with constipation and diabetes often eat sweet potato leaves, which can also help control blood sugar and relieve bowel movement.
