Small iron stone
Yam can be eaten with duck and rehmannia. Yam has the functions of invigorating spleen, quenching thirst, consolidating kidney and replenishing essence. Duck meat is rich in nutrition and has the functions of clearing away lung-heat, enriching blood, inducing diuresis and reducing swelling. Rehmannia glutinosa has the functions of nourishing yin, promoting fluid production, clearing away heat and cooling blood.
Pie-food phase grams:
Tomatoes: Tomatoes should not be eaten with pomegranate.
Yam: Yam and Gansui should not be eaten together; Nor should it be taken with alkaline drugs.

Simple leaves, alternate in the lower part of the stem, opposite above the middle, rarely 3 leaves; Leaves vary greatly, from oval triangle to broad oval or halberd; At seedling stage, leaves are generally broadly ovoid or ovoid, and the base is deeply heart-shaped. There are often bulbils in the axils of leaves.
Dioecious. Male inflorescence is a spike; Inflorescence axis is obviously serrated; Bracts and perianth segments have purple-brown spots; The outer perianth of male flower is broadly ovate. The female inflorescence is a spike, and the inflorescence 1-3 is inserted in the leaf axils.
Capsule is not reflexed, triangular oblate or triangular round; The seeds are inserted in the middle of the central axis of each locule and surrounded by membranous wings. The flowering period is from June to September, and the fruiting period is July-165438+1October.
It is distributed in Niutou Mountain, south of Huaihe River in Anhui, Jiangsu and Zhongshan in Guangdong. Korea and Japan are also distributed.
Tuber is a commonly used Chinese medicine "yam", which has the functions of strengthening and eliminating phlegm. And edible.
nutritional ingredient
Dioscorea zingiberensis, eaten by human beings since ancient times, is one of the earliest plants eaten by human beings. As early as the Tang Dynasty, Du Fu, a poet saint, had a famous sentence of "stuffing the intestines with many yams".
Dioscorea tuber is thick and juicy, sweet and soft, and sticky. Both raw and hot food are delicious.
According to the detection results of Chinese yam by Shandong Academy of Agricultural Sciences, its tuber contains crude protein 14.48%, crude fiber 3.48%, starch 43.7%, sugar 1. 14%, potassium 2.62%, phosphorus 0.2% and calcium 0.1.
Among the 18 amino acids needed by human beings, yam contains 16 amino acids.
Nutritional efficacy
The meat of Chinese yam is white, and it contains protein, vitamins, starch, calcium and phosphorus and other essential nutrients. Pharmacological research shows that mucopolysaccharide in yam can stimulate and regulate human immune system, and has anti-tumor, anti-virus and anti-aging effects.
Mucopolysaccharides combined with inorganic salts can form bones and make cartilage elastic.
The biggest feature of Dioscorea zingiberensis is that it contains a lot of mucin, which is a mixture of polysaccharide and protein. It has special health care function for human body, and can prevent fat from depositing in cardiovascular system, maintain vascular elasticity and prevent atherosclerosis from happening prematurely.
Saponins in yam have the functions of regulating blood pressure, lowering blood sugar, lowering blood fat and inhibiting tumor. At the same time, it is also beneficial to the protection of the stomach. The unique sticky texture of mucus can protect the stomach wall and reduce the pressure on the gastric mucosa.
Allantoin contained in Dioscorea opposita Thunb. has anesthetic effect, can promote epithelial growth, has anti-inflammatory and antibacterial effects, and is used for adjuvant treatment of chapped hands and feet and ichthyosis.
Tomatoes, also known as tomatoes and persimmons, are called June persimmons in ancient times, which is good news for three yuan. Originally from Peru and Mexico, it was originally named "Wolf Peach". Fruit is rich in nutrition and unique in flavor.
It can be eaten raw, cooked and processed into tomato sauce, juice or canned whole fruit. Tomato is one of the most widely planted fruits and vegetables in the world.
The United States, the former Soviet Union (Russian), Italy and China are the main producers. Europe, America, China and Japan all have large greenhouses, plastic greenhouses and other protection facilities.
It is widely cultivated in all parts of China. The planting area continues to expand. Native to South America; Widely cultivated in northern and southern China. There are big ones and small ones.
pharmacological action
Lycopene has strong antioxidant activity. In fact, the name of lycopene comes from tomato, which belongs to Solanaceae. Tomato is the most abundant food source of lycopene. Lycopene has the following pharmacological effects:
First, anti-aging
Lycopene is not only an important natural edible pigment in industry today, but also a strong antioxidant. Supplementing lycopene to the human body can help the body resist various degenerative and aging diseases caused by free radicals.
Second, reduce cardiovascular diseases.
The degradation effect caused by free radicals is the number one culprit of cardiovascular diseases. Once the chain reaction of lipid peroxidation in blood occurs, fatty acids will polymerize. When these macromolecular lipid polymers are deposited on the wall of blood vessels, they will harden and block blood vessels.
Clinical trials in several European medical research centers show that lycopene has a strong antioxidant effect, which can effectively reduce and prevent cardiovascular diseases and reduce the risk of cardiovascular diseases.
Third, prevent cancer.
Lycopene can effectively eliminate free radicals in the body, prevent and repair cell damage, and inhibit DNA oxidation, thus reducing the incidence of cancer. Lycopene also has biochemical functions such as cell growth regulation and intercellular information induction.
It can induce cell connection and communication, ensure the transmission of normal growth control signals between cells, regulate the proliferation of tumor cells and play an anti-cancer role. Studies have shown that lycopene can effectively prevent prostate cancer, digestive tract cancer, liver cancer, lung cancer, breast cancer, bladder cancer, uterine cancer, skin cancer and so on.
toxicity
The toxicity of lycopene is very small, and no toxic reaction has been found after long-term high-dose oral administration, which may be due to insufficient absorption. Subcutaneous injection can cause local necrosis, and its ointment (used to treat mycosis) is not irritating to skin, but may be irritating to mucosa.
Intravenous injection to rats or rabbits can cause a sudden and short-term drop in blood pressure, but it has no effect on heart rate, and can cause hemolysis in vivo and in vitro.
