White raw materials: white radish, onion, garlic, oysters, scallops, chicken, milk and dairy products. Health care effect: white radish contains hydrogen sulfide, which can decompose carcinogens, activate enzymes and inhibit tumors. Allicin and sulfide contained in onion and garlic, and gingerol contained in ginger all have antioxidant effects. Oysters have the highest zinc content in food, which can strengthen immune function. Casein in dairy products can be digested into various peptides to enhance immunity. Red ingredients: tomato, grapefruit, red pepper, shrimp, salmon, etc. Health care efficacy: Lycopene in tomatoes and grapefruit, capsanthin in red peppers, astaxanthin in shrimp and salmon all have antioxidant and anticancer effects. Green ingredients: spinach, lettuce, broccoli, Chinese cabbage, cabbage, rape, peas, edamame, kiwi fruit, green tea, etc. Health function: Green food contains α and β carotene, chlorophyll, vitamins C and E, and has antioxidant effect. Brown ingredients: whole wheat flour and its products, whole grains, mushrooms, nuts, etc. Health efficacy: Vitamin E, phytic acid and flavonoids in whole wheat flour products can prevent cell canceration, vitamin B can help activate cancer-inhibiting enzymes, and dietary fiber can promote intestinal detoxification. Phytic acid rich in whole grains is an antioxidant, which can inhibit the activity of cancer cells, enhance the immune system and reduce intestinal cancer. Mushrooms all contain β-glucan, which can improve immunity, inhibit the occurrence of cancer cells and promote the activation of macrophages and natural killer cells. Nuts are rich in vitamin E, linolenic acid, selenium and phytic acid, which can enhance the phagocytosis of white blood cells and destroy cancer cells. Yellow ingredients: carrots, pumpkins, sweet potatoes, corn, soybeans, egg yolks, oranges, Liu Ding, etc. Health Efficacy: Chlorophyll and lutein contained in carrots, pumpkins, sweet potatoes and egg yolks, zeaxanthin contained in corn, isoflavones contained in soybeans and cryptoxanthin contained in oranges and oranges can inhibit carcinogens and protect cells from damage. Purple ingredients: perilla, blueberry, purple cabbage, eggplant, red wine, etc. Health Efficacy: Anthocyanins contained in perilla, blueberry, purple cabbage and eggplant can avoid the damage of free radicals to microvessels, promote retinal regeneration and protect genes and cells. Polyphenols contained in red wine can play a powerful antioxidant role and prevent cancer and chronic diseases. Black ingredients: kelp, black sesame, black beans, etc. Health care effect: Sesamic acid contained in black sesame seeds and melanin contained in black beans have strong antioxidant effect. U- soluble polysaccharide polymer contained in kelp can promote cell decomposition of enzymes, destroy cancer cells and make them fail and die.
