As the saying goes, "In spring, eat flowers; in summer, eat leaves; in autumn, eat fruits; in winter, eat roots." Winter is a particularly good season for root vegetables. As the name suggests, root vegetables are those with fleshy roots as their edible parts, mainly including sweet potatoes, radishes, Chinese yams, taro, bamboo shoots, lotus root, and burdock. Compared to other types of vegetables, root vegetables have lower pesticide residues, are rich in carbohydrates, and can replace a portion of staple foods. They are inexpensive, can be stored for a period in cold environments, and are suitable for storage. So, what are root vegetables? What are their nutritional values? Let's find out.
1. Potato
"The king of treasures, the potato, indispensable for every meal." Potatoes can be used as both grain and vegetables, nutritious and available year-round. Potatoes are characterized by high yield, early maturity, wide distribution, and multiple uses. They contain a comprehensive range of nutrients, are high in calories, and contain minerals, carotene, vitamin C, and dietary fiber. Potatoes have vitamin C, which is not found in cereals, and carbohydrates, which are lacking in vegetables. Eat potatoes often in winter and in dry climates, as their sweet and neutral nature can nourish the spleen and stomach, replenish qi, moisten the intestines, and hydrate the skin. Some people worry that eating potatoes will cause weight gain. In fact, as long as the cooking method is appropriate and the intake of staple foods is reduced accordingly, potatoes not only do not cause weight gain but can also help with weight loss.2. Weiqing Radish
Radishes generally have a high water content, up to 94%, but are low in calories. They are rich in dietary fiber, minerals, vitamin C, and folic acid, with a vitamin C content even higher than that of many common fruits. Radishes contain a large amount of amylase, which can break down starch and aid digestion; the mustard oil they contain has an appetite-stimulating effect. Traditional Chinese medicine considers them sweet and pungent in taste, slightly cool in nature, and they can strengthen the stomach, aid digestion, relieve cough and reduce phlegm, regulate qi, and promote urination. Weiqing radishes have green skin and flesh, thin skin, fine texture, high water content, and high sugar content, with a crisp, sweet, and slightly spicy taste that is refreshing. Therefore, Weiqing radishes are best eaten raw. When you've eaten too much greasy food and have lost your appetite, chewing one or two pieces of radish can not only stimulate your appetite but also has the effects of reducing phlegm, clearing heat and detoxifying, strengthening the spleen and regulating qi, and reducing internal heat.3. Taro
Taro, also known as Taro Nuts, is rich in nutrients. Its texture is soft, fine, sweet, and glutinous, with a high rate of digestion and absorption, making it an excellent alkaline food. Taro contains about 13% carbohydrates, mainly starch; about 2% protein, and low fat content. Taro contains a mucoprotein, which, when absorbed by the human body, produces immunoglobulin, enhancing the body's resistance. In addition, taro is also rich in potassium, calcium, carotene, vitamins, and other components.4. Burdock
Burdock has a similar appearance to Chinese yam but has no protrusions or root hairs on its surface and is even harder in texture. Burdock is rich in fiber, various minerals, and vitamins needed by the human body. Burdock enjoys the reputation of "king of vegetables" and is often hailed as a nutritional health product. In fact, burdock is also one of the many root vegetables, with the outstanding feature that it contains various active substances with good antioxidant and anti-swelling detoxification effects. Burdock is also rich in dietary fiber, which can promote intestinal peristalsis, aid bowel movements, lower cholesterol in the body, and reduce the accumulation of toxins and waste.
