如果你有psoriasis, you know that捕鱼大作战 like topical steroids, oral retinoids, or biologics can help calm the itch and formation of the plaques that stress out your skin. But certain lifestyle shifts that go beyond你如何洗澡or what you wear may help soothe the chronic inflammatory condition, too.

“Since psoriasis is an immune-mediated disease, diet can be very powerful. This is because免疫系统的三分之二[or nearly 70% of immune cells] is located in the gut,” explains saysMicah Yu，医学博士，一位综合风湿病学家，在加利福尼亚州纽波特海滩（Newport Beach）获得风湿病学和内科医学的董事会认证。

确实，最近的一项实验室研究表明what you eat（即，当它是高脂，高度加工的西方饮食时）可以迅速拨打体内的炎症水平，并可能使牛皮癣的症状恶化。因此，我们去了专家，看看采用更基于植物的饮食方式 - 加载蔬菜，豆类，全谷物和水果以及限制动物产品 - 应该做出相反的状态，并应在牛皮癣中占有一席之地关心。

牛皮癣的炎症如何发挥作用

银屑病is caused by an overactive immune system, although why the immune system is revved up is not entirely understood, according to a study in the牛皮癣和银屑病杂志。

Here’s what we do know: Chronic inflammation is the result—and, in turn, the culprit of psoriasis symptoms. In psoriasis, that inflammation causes skin cell growth to speed up, which leads to new cell growth every few days—versus the usual 28-day cycle whereby skin cells form only as old cells shed. This overproduction results in an accumulation of skin cells on the surface of the skin, leading to scaly patches (a.k.a. plaques) and red, itchy spots.

That’s why your dermatologist likely prescribes not only skin-care treatments for topical TLC of psoriasis symptoms but also medications to address the root cause of the inflammation. It’s this inflammation-fighting part of the solution where good nutrition may offer a helping hand.

Of the various factors that can influence psoriasis, such as genetics and infections that trigger flares, many are out of our control. “There is one factor that is completely in your hands—and that’s your diet,” says Anna Chacon, M.D., a board-certified dermatologist practicing in Miami, FL.

The Science on Plant-Based Diets and Psoriasis

那么，您应该怎么吃以最好地帮助牛皮癣呢？研究指出了一种基于植物的饮食与西方饮食。

According to a recent report published in theJournal of Dermatological Treatment，牛皮癣的患者食用更多的蔬菜，疾病的严重程度较低，而食用红肉的人的疾病严重程度较高。

这种差异背后的一个潜在原因：某些食物会触发特定的炎症蛋白。还记得上述实验室研究，将西方饮食和牛皮癣联系起来吗？研究人员发现，喂养这种高脂，加工食品四个星期的小鼠具有较高水平的白介素-23，这是一种与牛皮癣等炎症性疾病直接相关的免疫导致蛋白质。

同时，基于植物性的植物性可能对您的肠道微生物组有益 - 肠道中生活的细菌系统可能在牛皮癣的起源中起关键作用。国际分子科学杂志。

“Increased intake of fiber and other plant components associated with plant-based diets increase the growth of beneficial gut bacteria, reducing inflammation,“ Dr. Chacon says. For example, plant-based foods contain双歧杆菌和乳杆菌，细菌以其抗炎特性而闻名。

据称，多种细菌的增加可能有益于产生弹性免疫系统，甚至比以红肉为基础饮食的人更有益学习。同时，肠道细菌的多样性和较低的水平of Bacteroidetes (anti-inflammatory organisms that live in our gut) has been linked with a higher risk for inflammatory diseases such as PsO, perresearch。

Yet another study published in the欧洲营养杂志发现吃五个星期的高纤维的人会降低C反应蛋白，这是一种在肝脏中生产的蛋白质，在免疫介导的疾病患者中升高。

如何采用更基于植物的饮食方式

You don’t have to go full vegan—cutting out meat and dairy entirely—or even become vegetarian to benefit from a more plant-based diet, Dr. Yu says. If you do want to start incorporating more plant-based foods into your diet, Dr. Yu recommends filling your plate with not just fruits and veg, but other whole foods like beans, legumes, quinoa, and brown rice.

About how much? Aim for some 90% of your plate to be filled with plant-based foods, recommends Dr. Yu.

根据美国农业部针对美国人的饮食指南，您的典型餐厅应包括：

• 50% veggies and fruits

• 少于25％的谷物，其中一半是全谷物

• A type of protein (poultry, seafood, eggs, beans, legumes, or nuts for example); the percentage is dependent on your unique needs. (Check outmyplateto determine yours.)

Rather than having red meat to fill that protein spot, try lentils, quinoa, beans, eggs, and protein-rich greens like spinach, collard greens, and broccoli—while focusing on lean animal proteins like salmon and chicken, Dr. Yu says, who recommends following theMediterranean diet，每天几次消耗几次饮食方式，是每天几次食用几次饮食，植物性食品和健康脂肪（如橄榄油和鳄梨）是乳制品，鸡蛋，海鲜和家禽等动物产品。

Yu博士说，当交换基于植物的替代品时，请务必阅读标签，因为某些产品对您来说不一定更健康。他说：“许多假肉是超级加工的。”“其中很多是人造的。它们还含有粉末和盐。”

The Bottom Line on Plant-Based Eating and Psoriasis

您应该始终与皮肤科医生一起使用有效的治疗计划来治疗牛皮癣斑块，但同时改变生活方式，有助于减少与疾病相关的全身性炎症可以有所作为。吃更基于植物的或植物性的饮食可能会帮助您做到这一点。通过加载健康的纤维并增加肠道细菌的多样性，您可以改善免疫功能并减少慢性炎症。

Yu博士说：“吃抗炎食品对所有人都非常重要，尤其是对于牛皮癣的人。”

您的第一步：与您的医疗保健提供者和/或皮肤科医生交谈，以查看这种饮食方式是否适合您。

Chacon博士补充说，值得一提的是，基于植物的饮食可能并不适合所有人。她说：“由于他们可能拥有的其他健康状况，有些人可能不适合进行植物性饮食。”“这就是为什么如果您决定对饮食进行重大改变，请咨询医生总是很重要的。”
