Some foods contain photosensitive factors. Exposure to sunlight or other strong light after consumption will increase the activity of melanocytes, causing the skin to darken or have spots. Photosensitive foods include: lemon, white radish, papaya, celery, lettuce, potato, coriander, amaranth, rape, eggplant, seaweed, snail, spinach, fig, nine-story pagoda, leek, red bean, and mango.

So after a meal, you can use strawberries as your after-meal fruit, but never papaya, citrus and mango, because they are rich in B-carotene and eating too much can easily cause pigmentation.

The so-called acidity and alkalinity of food refers to whether the inorganic salts in food are acidic or alkaline. Generally, the oxides of metal elements such as sodium, calcium, and magnesium are alkaline in the human body. Foods containing more of these elements are alkaline foods, such as soybeans, tofu, spinach, lettuce, radish, potatoes, lotus roots, onions, etc. Kelp, watermelon, banana, pear, apple, milk, etc. Some foods contain a lot of non-metallic elements, such as phosphorus, sulfur, chlorine, etc. After oxidation in the human body, they generate acid radicals with anions, which are acidic foods. Such as pork, beef, chicken, duck, eggs, carp, oysters, shrimp, as well as flour, rice, peanuts, barley, beer, etc. Foods that make the blood weakly alkaline or alkaline foods have a nutritional effect on the brain, including tofu, peas, celery, lotus seeds, eggplants, cucumbers, mushrooms, milk, spinach, watermelon,...
