Catching 15 minutes of sunlight three times a week and drinking water instead of sugary drinks are two of the easiest and most natural ways to protect against liver cancer and other types of liver damage when you live with hepatitis B.
Sunlight doesn’t cure hepatitis B, but it spurs production of vitamin D, which appears to help prevent a number of cancers and other liver problems.
The liver appears to play a vital role in metabolizing vitamin D, and when you have healthy vitamin D levels, your body’s cells behave and grow normally. But when you have a vitamin D deficiency, communication between your cells breaks down, which can lead to abnormal cell growth and cancer.

Studies are finding that hepatitis B patients who have vitamin D deficiency often have higher viral loads and rates of liver damage, cirrhosis and cancer, which is troubling because one-third to one-half of people with hepatitis B are deficient in vitamin D.
A recent study, published in the Clinical Gastroenterology and Hepatology, followed 426 hepatitis B patients for more than 13 years. Those with vitamin D deficiency had twice the number of “clinical events,” including liver damage and cancer, than patients with normal vitamin D levels.
Patients with normal vitamin D levels were also twice as likely to seroconvert and lose HBeAg and develop “e” antibodies (called HBeAg seroconversion), which leads to lower levels of hepatitis B virus (viral load) in their bodies.
But don’t reach for those vitamin D supplements just yet. Grace Hong, associate professor of gastroenterology and hepatology at The Chinese University of Hong Kong and lead author of the study, says supplements aren’t needed unless patients have serious vitamin D deficiencies.
“I advise my hepatitis B patients to make life style modification to increase their vitamin D levels,” she said, which includes getting outside to soak in some sunlight and consuming foods rich in vitamin D and juices and milk fortified with vitamin D. “Prescribing vitamin D would only be indicated when there is evidence of vitamin D deficiency and much reduced bone mineral density,” she added.
While most people get the vitamin D they need through sunlight, they also get it from fatty fish, fish liver oil, eggs, and prepared foods fortified with vitamin D, such as breakfast cereal.
The Institute of Medicine of the National Academies recommends sunlight exposure and the following daily recommended dietary allowance of vitamin D:

• 15 micrograms (μg) per day or 600 international units (IU) for children, teens and adults up to age 70, including women who are pregnant or lactating.
• And 20 μg per day or 800 IU per day for seniors age 71 and older.
  

While 90 percent of the body’s vitamin D comes from sunlight, the amount of time in the sun needed to generate vitamin D is actually quite small. In northern areas, such as Boston, with limited sunlight, only 10 to 15 minutes of sun exposure three times a week is needed during winter, and only five to 10 minutes in summer. Longer exposure to the sun does not increase vitamin D production.
In addition to sunlight, remember to avoid sugary drinks on hot summer days. A daily sugary drink increases the risk for fatty liver disease, which can exacerbate a hepatitis B infection. Read more about how sugary drinks harm your liver.
Summer is also a great time to eat healthy foods. Learn more about how much protein you really need in a healthy diet.

醒目的阳光15分钟，每周三次，喝，而不是含糖饮料水是两个防止肝癌和其他类型的肝损害，当你生活在乙肝的最简单，最自然的方式

阳光不能治愈乙肝，但是马刺产生维生素D，这似乎有助于预防多种癌症和其他肝脏问题。

肝脏似乎在代谢维生素D起着至关重要的作用，而当你拥有健康的维生素D水平，你的身体细胞的行为和正常生长。但是，当你有维生素D缺乏症，你的细胞之间的通信发生故障时，这可能会导致异常细胞生长和癌症。

研究发现，乙型肝炎患者谁具有维生素D缺乏往往有更高的病毒载量和肝损伤，肝硬化和癌症，这是麻烦的速率，因为三分之一到二分之一的人患有乙型肝炎缺乏维生素D.

最近的一项研究，发表在临床胃肠病学和肝病，随后426乙肝患者超过13年。那些与维生素D缺乏过的数量的两倍“临床事件”，包括肝损伤和癌症，比正常的患者的维生素D的水平。

正常的患者的维生素D水平也两倍于血清转化，失去HBeAg和发展的“e”抗体（称为HBeAg血清学转换），从而导致乙肝病毒（病毒载量）在他们的身体的较低水平。

但没有达到对于那些维生素D补充剂，只是还没有。格雷斯港，胃肠病和肝病学副教授在香港的中国大学和研究的主要作者，表示没有必要补充，除非病人有严重的维生素D缺乏。

“我建议我的乙肝患者进行生活方式的修改，以增加他们的维生素D水平，”她说，这包括让外面一些阳光浸泡和消费富含维生素D和果汁和牛奶强化维生素D.“处方当出现维生素D缺乏和大大降低骨密度的证据维生素D将只表示，“她补充说。

虽然大多数人得到他们通过阳光所需要的维生素D，他们也得到了来自脂肪的鱼类，鱼肝油，鸡蛋，强化维生素D的准备的食物，如谷类早餐。

美国国家科学院医学研究所建议的阳光照射和维生素D的每日以下推荐膳食津贴：

    每天15微克（微克）或600国际单位（IU）的儿童，青少年和成人达70岁，其中包括妇女谁是怀孕或哺乳期。
    和20微克每天，或每天800国际单位的老人71岁及以上。

而90％的体内的维生素D来自阳光，时间在需要产生维生素D的太阳的量实际上是相当小的。在北部地区，如波士顿，与太阳光的限定，每周仅10至15分钟的阳光照射三次在冬季需要，只有5至10分钟在夏季。再暴露在阳光下不增加维生素D的生产。

除了阳光，记得要避免在炎热的夏天含糖饮料。每天喝含糖增加了脂肪肝疾病的风险，这可能会加剧乙肝感染。了解更多关于如何含糖饮料会损害您的肝脏。
