A person's skin color is determined by innate factors such as race and genetics, and is closely related to the distribution of capillaries, the amount of pigment, and the thickness of subcutaneous fat. The normal skin color should be ruddy and lustrous. In addition to diseases such as anemia and hepatitis, improper diet can also affect a person's skin color.
Flushing—Facial flushing is mostly caused by drinking alcohol. It can occur even if the alcohol concentration is not high and the amount consumed is small. In addition to the face, it can extend to the neck, trunk, and limbs, sometimes accompanied by wheals and itching, affecting work and rest. This is an irritant and allergic reaction caused by alcohol. People who have this reaction should drink less alcohol or quit drinking. Vinegar, water chestnut soup, or *Siraitia grosvenorii* effervescent granules can be used to sober up. If necessary, vitamins B, B, C, or drugs such as chlorpheniramine can be taken.
Cyanotic red complexion—Cyanotic red may be caused by eating too many lychees. This is because lychees are high in fructose. After consuming a large amount, the liver's glucokinase cannot convert the fructose into glucose in time, causing a large amount of fructose to accumulate in the blood and change the skin color, which can in turn cause physical discomfort. Lychees should be eaten reasonably, scientifically, and in moderation. After eating lychees, drink more water to speed up the excretion of fructose. You can also mash bay leaves or chicory root juice to drink to relieve cyanotic skin.
Red complexion—Red complexion may be caused by poor blood circulation, especially poor blood flow in the peripheral parts, and the incomplete digestion of protein before absorption. To ensure the full digestion and absorption of protein, eat more foods containing vitamins B and C, and get more sun exposure. Regular bathing and massage can speed up blood circulation and reduce the phenomenon of red skin.
Bluish-red skin—Bluish-red skin may be caused by histamine in food. After animals such as shrimp, crab, and eel die, the protein in their bodies decomposes rapidly, producing a large amount of histamine. Eating these aquatic products will increase the histamine content in the human bloodstream. For those who eat improperly or are allergic, the face or even the whole body's skin will turn bluish-red, accompanied by general discomfort, sometimes with headaches and severe itching. If the symptoms are severe, antihistamine drugs can be used for treatment.
Flushed makeup—Flushed makeup refers to red cheeks, mostly caused by excessive intake of animal fats and proteins. When consuming more animal fats and proteins, it should be supplemented with fresh vegetables containing a large amount of chlorophyll.
Orange-yellow—Skin discoloration to orange-yellow caused by diet mostly occurs on the palms and soles and is caused by carotene. Foods rich in carotene include citrus fruits, carrots, tomatoes, daylilies, etc. Egg yolks and butter also contain small amounts of carotene. If you consume too many high-carotene foods in a short period of time, the carotene content in the blood will increase sharply and accumulate in large amounts in the skin, causing the palms, soles, and face to appear orange-yellow. Stop eating foods containing carotene, drink more water to promote the excretion of carotene, and the orange-yellow color will fade after a period of time.
Yellowish-black—Too much salt can cause the skin to appear yellowish-black. Controlling salt intake, drinking more water, bathing frequently, and sweating more can all help to excrete salt.
Oily black complexion—Oily black complexion is mostly caused by eating too much rapeseed oil, sesame oil, etc. The intake of rapeseed oil should be reduced, and more fresh vegetables containing chlorophyll should be eaten.
