Eat kiwi fruit often
What are the benefits for the body?
Beauty and skincare: Kiwi fruit is rich in vitamin C, which is naturally beneficial for skin health. The main component of the skin is collagen, and vitamin C can participate in the synthesis of collagen, maintain the elasticity of the skin, and reduce the production of skin wrinkles.
In addition, vitamin C is also a strong antioxidant, which can help the body remove excess free radicals, prevent lipid peroxidation, and also help protect the skin.
Protection of the gums: If the diet is deficient in vitamin C, there is a disorder in collagen synthesis, resulting in slow wound healing and increased fragility of the capillary wall, which can lead to bleeding. Common is bleeding and loose gums, and severe gum recession and even loose teeth and loss of teeth.
Eating 1 kiwi a day to ensure adequate vitamin C intake can help us have a healthy mouth.
Prevention of constipation: The dietary fiber content of kiwifruit is relatively high in fruits, and the insoluble dietary fiber content is 2.6g/100g, which is 1.5 times that of apples and 2.2 times that of bananas. Insoluble dietary fiber can promote the mechanical movement of the gastrointestinal tract, promote the excretion of feces, and prevent constipation.
If it is a kiwi fruit that has almost no hair, it can also be washed and eaten to eat the skin, and you can consume more dietary fiber.
Strong bones: Kiwi fruit is rich in vitamin C in addition to vitamin C, both of which are beneficial for bone health and can prevent osteoporosis.
Vitamin C deficiency can cause impaired collagen synthesis, which can lead to poor bone organic matter formation and osteoporosis. Vitamin K can promote calcium deposition in bones, "leading calcium into bones" is conducive to the absorption of calcium by bones, can promote osteoblasts and inhibit osteoclasts, and has obvious effects on preventing fractures.
Finally, it should be reminded that if the kiwi fruit you buy is relatively hard, you can mix it with apples and bananas at room temperature to make the kiwi soft and sweet.
If the kiwi fruit bought is already slightly soft, it is recommended to refrigerate it at 4 °C, which can slow down the further softening of the fruit, extend the shelf life, and better retain vitamin C.
