1. Pteridium aquilinum should not be eaten with edamame, rice, peanuts and peas. The reasons are as follows: \xd\1. Pteridium aquilinum and edamame: It affects the absorption of nutrients, which is not conducive to human growth and brain development, and also affects human metabolism. \xd\2. Pteridium aquilinum and rice: Reducing the digestion and absorption of vitamin B1 is not conducive to human digestion and absorption of vitamin B1, and is not conducive to human growth and brain development. \xd\3. Pteridium aquilinum and peanuts: It will reduce the nutritional value of Pteridium aquilinum and peanuts, which is not conducive to human digestion and absorption of nutrients, and is not conducive to human growth and development. \xd\4. Pteridium aquilinum and pea: It will reduce the nutritional value of Pteridium aquilinum and pea, affect human metabolism, and is not conducive to human growth and brain development. \xd\\xd\ II. < P > Extended information: About Pteridium aquilinum var. latiusculum, also known as fist dish, cat's paw and bibcock dish, is fond of being born in sunny plots in shallow mountainous areas and mostly distributed in sparse mixed forests of conifers and broadleaves. Its edible part is unexpanded young leaf buds. \xd\2. Growing environment: \xd\(1) Pteridium aquilinum has strong stress resistance and wide adaptability. A sunny, humid and cool climate. It is resistant to both high temperature and low temperature, and can still grow normally at 32℃. Roots can safely overwinter at -36℃, while young leaves suffer from freezing injury at -5℃. When the ground temperature is 12℃ and the air temperature is 15℃, leaves begin to grow rapidly, and the suitable temperature for spore development is 25~3℃. \xd\(2) Pteridium aquilinum is sensitive to light, and can grow normally under strong light and weak light, but it grows fast and grows strong and tall under the condition of long light hours. It is very strict with water and is not resistant to drought. The soil requires rich organic matter, deep soil layer, good drainage, neutral or slightly acidic. \xd\3. Main value: The starch extracted from the rhizome of this species is called fern powder for food, and the fiber of the rhizome can be used to make rope and cable, which is resistant to water and moisture, and the tender leaves are edible, so it is called fern; The whole plant is used as medicine to expel rheumatism, diuretic and antipyretic, and can also be used as an insect repellent. This species is called "rice fern" in southern Sichuan, and it is said that its starch quality is not as good as that of Pteridiumrevolutum(Bl.)Nakai.
