Dietetic beauticians warn people that in daily life, you eat too many fish and eggs, which are acidic foods. If you continue to eat them without restraint, organic acids will not be excreted in time, sensitive epidermal cells will be eroded, and your skin will lose its tenderness and elasticity. Maybe you don't like the following foods, but in order to be a little beauty, you should treat them as delicious! Shark's fin and salmon head: Eating more chondroitin sulfate in the diet can increase skin elasticity and tighten skin. Many of these foods contain chondroitin, and shark's fin contains the highest amount of protein and animal gum, which can not only accelerate metabolism, but also make skin smooth and nourishing. Pig bone soup, cow bone soup and chicken bone soup: These soups are also rich in chondroitin, which can keep the skin elastic and delicate if eaten regularly. Because the dermis is composed of elastic fibers, and the most important substance that constitutes elastic fibers is chondroitin sulfate. Without this substance in the human body, the skin will lose its elasticity. Vegetables, fruits and bean products: These foods are alkaline foods. Regular consumption can make the blood weakly acidic, reduce the contents of lactic acid and urea, and make the skin full of elasticity. Sesame: Fresh sesame contains complex fatty acids, high-quality oils, calcium, phosphorus and vitamins. It has a good effect on enhancing skin luster and elasticity. It's best not to cook it completely, but to eat it half-cooked. Skin: Skin is a treasure, which can improve the water storage function of tissues and cells, and collagen in it can effectively reduce fine lines and keep skin smooth. Nuts: Eating nuts such as walnuts and pine nuts often can make muscle fibers that support fat strong.
