白癜风作为一种皮肤色素脱失性疾病，病因难明，疗效欠佳，治愈率低，复发率高，是世界医学皮肤学科尚未解决的难题. 白癜风是可以治愈的，但是遇到诱发因素极易反复。
预防控制要点：要避免过强的紫外线照射，如海边的日光浴、登山等，适量的紫外线对白癜风的治疗是有帮助的。 饮食上需要稍加注意的。多吃一些含有酪氨酸及矿物质的食物，如肉（牛、兔、猪瘦肉）、动物肝脏。以及核桃、黑芝麻、香菇、黑米等富含黑色素的食物，忌烟酒刺激及易敏物质， 少吃含VC多的食物。

我们要正确的理解白癜风，白癜风是中慢性顽固性的疾病，但白癜风是不会传染给别人的，做好以下几点可以预防白癜风患者发病：
一、加强自身休养，保持乐观情绪  人们在生活和工作中会经常遇到一些困难和不愉快的事情，给心理和精神上造成压力，如不及时进行化解，即会造成机体生理功能紊乱而导致许多疾病的发生。据美国生理学家爱尔马研究分析，人在生气时会分泌一种毒素，使自体中毒而发生许多疾病，如过敏、肿瘤及某些皮肤病等。所以在生活与工作中要加强自身休养，提高自已对环境的应变能力，以适应环境变化。“处世不惊”这句名言即是告诉人们遇事要以冷静的态度去对待客观事物的变化，再经过主观努力将不利因素转变为有利因素，即所谓“将压力化为动力”。只要一个人对自已的生活充满信心，对事业充满希望，并有坚定的信念和为事业而顽强的拚搏精神，就一定能够战胜一切困难，成为生活的强者。另外，每个人都应以宽阔胸怀，少一点忌妒心，处理好家庭和同志之间的关系。做好这些就能够克服一切不良环境因素的刺激，始终保持乐观情绪。   二、避免环境及食品污染对人体的损害  人口的迅速增长和工业的快速发展，使生态环境受到了不同程度的破坏。保护环境，减少污染已为各国所重视，我国政府目前正加大治理环境的力度。但完全治理好环境是一项较长期的工程，做为每个人则可以采取一些有效的自我防护措施，避免或减少有害物质对机体的损伤。  1)减少接触有害物：尽量减少接触化工原料，油漆涂料等，如新装修的房子要经过3个月以上充分通风干燥后使用，接触化学原料的工作要做好劳动防护措施。  2)减少从口进入有害物：蔬菜、水果食前要反复以净水冲洗，以减少残留农药等有害物。儿童食 用水果应去皮。不食用重金属盐超标食品，如所含汞、铅等重金属盐超标食品。  3)减少自呼吸道进入的有害物：不在马路或烟雾尘埃大的场所做剧烈运动，如跑步等运动。  4)减少紫外光的照射：长时间暴露在强光下应采取防晒措施，如旅游、海浴时将裸露的皮肤涂以防晒霜。临床可见于旅游、游泳后发病的较多。   三、纠正偏食、养成良好的饮食习惯  偏食必然会造成人体营养素摄入不足及比例失调。不同种类食物所含营养素的成份有较大差异，如米类富含蛋白质、面类富含淀粉，动物性食品富含动物蛋白质及脂肪，蔬菜水果含有果糖、纤维素，还含有各种维生素。西红柿、甘桔等酸类水果维生素C含量较多，B族维生在谷类外层中含量高，各类食物虽然均含有不等量微量元素，但以菌类干菜及黑色食物含量较高。人类在长期进化过程中养成了每日三餐的饮食规律，和食物种类的科学搭配，保证人体所需各类营养物质的摄入。如果长期打乱正常饮食规律，会引起消化功能减弱，食欲减退，甚至导致消化道疾病的发生，使营养素摄入不足。

I ask how can we prevent the next vitiligo, my home, my wife is a vitiligo patient, every day to live together on, we are afraid of suffering from the disease have this damn ah. How to prevent hoot? Thank you!

We must correct understanding of vitiligo, vitiligo is the chronic intractable disease, vitiligo is not contagious to other people, do the following to prevent onset of vitiligo:
First, to strengthen their own rest and maintain optimism? People live and work in difficult and often encounter some unpleasant things to the psychological and emotional pressure, if not promptly resolved, that will cause the body caused by physiological dysfunction many diseases. According to the American physiologist Ai Erma analysis, people get angry when the secretion of a toxin from the body poisoning occurred to many diseases, such as allergies, cancer and certain skin diseases. So in life and work to strengthen their own resort, the strain on the environment to improve their own ability to adapt to environmental changes. "Attitude of life is not scared," famous words is wise to tell people to calm attitude towards the changes of objective things, through the subjective to the unfavorable factors into favorable factors, the so-called "the pressure into motivation." As long as one person living on their own confidence in the cause of hope, and have firm faith and for cause and indomitable fighting spirit, we will be able to overcome all difficulties, to become the stronger of life. In addition, each person should be based on broad minded, less jealousy, deal with the relationship between the family and comrades. Do all of these will be able to overcome adverse environmental stimuli, and always maintain optimism. ? Second, avoid food contamination of the environment and harm the human body? Rapid population growth and rapid development of industry, the ecological environment has been varying degrees of damage. Protection of the environment, reduce pollution has been valued by various countries, our Government is increasing environmental management efforts. However, good governance environment is entirely a longer-term projects, as each person can take some effective Ze's self-protective measures to avoid or reduce harmful Wu Zhi on the body of 损伤. ? 1) to reduce exposure to harmful material: to minimize contact with chemicals, paints and other coatings, such as the newly renovated house has to go through more than 3 months after the use of adequately ventilated drying, exposure to chemical raw materials, labor protection measures work to do. ? 2) reduction of harmful substances into the mouth: vegetables, fresh fruit before washing repeatedly with water to reduce pesticide residues and other harmful materials. Fresh fruits should be peeled with children. Excessive consumption of heavy metal salt is not food, such as the mercury, lead and heavy metal salts excessive food. ? 3) reduction of harmful substances from the respiratory tract into: do not smoke, dust, road or place a large heavy exercise such as running and other sports. ? 4) to reduce UV exposure: Prolonged exposure to bright light should take protective measures, such as tourism, sea bath will be coated with sunscreen on exposed skin. Clinical seen in tourism, and swimming after the onset of more. ? 3, correct the partial eclipse, develop good eating habits? Partial eclipse will definitely lead to inadequate nutrient intake and body imbalance. Different types of nutrients contained in the food ingredients are quite different, such as protein-rich rice, noodles are rich in starch, animal products rich in animal protein and fat, fruits and vegetables contain fructose, cellulose, also contains various vitamins. Tomatoes, kumquat fruit acids such as vitamin C content of more, B family living in the outer layer of high grain, although various types of food contain different amount of trace elements, but the dried vegetables and black fungus with higher levels of food. In the long-term evolution of human develop the law of three meals a day diet, and food science with a kind of guarantee needed by the body's intake of various nutrients. If long-term disruption of normal diet rules, will lead to digestive function, and loss of appetite, gastrointestinal diseases and even lead to inadequate nutrient intake.
