Psoriasis occurs when the immune system mistakenly attacks normal tissues in the body. This reaction leads to swelling and a quicker turnover of skin cells.

由于过多的细胞升至皮肤表面，身体无法足够快地将其脱落。他们堆积起来，形成瘙痒，红色的斑块。

牛皮癣可以在任何年龄发展，但通常发生在15至35岁之间的人中。主要症状包括瘙痒，红色的厚皮肤，并在：

  • 肘部
  • 膝盖
  • 头皮
  • back
  • face
  • 手掌
  • 脚

牛皮癣可能会刺激和压力。面霜，软膏，药物和light therapymay help.

However, some research suggests diet might also alleviate symptoms.

So far, research on diet and psoriasis is limited. Still, some small studies have provided clues into how food may affect the disease. As far back as 1969, scientists looked into a potential connection.

Researchers published a study in the journal Archives of Dermatology 这表明低蛋白饮食和牛皮癣爆发之间没有联系。然而，最近的研究发现了不同的结果。

低热量饮食

Some recent research shows that a low-fat, low-calorie diet may reduce the severity of psoriasis.

In a 2013 study published in JAMA Dermatology , researchers gave the people involved in the study a low-energy diet of 800 to 1,000 calories a day for 8 weeks. They then increased it to 1,200 calories a day for another 8 weeks.

The study group not only lost weight, but they also experienced a trend in decreased severity of psoriasis.

研究人员推测，患有肥胖症的人会在体内炎症，使牛皮癣恶化。因此，增加减肥机会的饮食可能会有所帮助。

无麸质饮食

那无麸质饮食呢？可以帮忙吗？根据一些研究，这取决于该人的敏感性。患有腹腔疾病或小麦过敏的人可能会避免麸质来缓解。

A 2001研究 found that people with gluten sensitivities on gluten-free diets experienced improvement in psoriasis symptoms. When they returned to their regular diet, the psoriasis worsened.

A 2005 study 还发现有些牛皮癣患者对面筋的敏感性升高。

Antioxidant-rich diet

Though fruits and vegetables are an important part of any healthy diet, it may be especially important for patients with psoriasis.

A 1996 study 例如，发现胡萝卜，西红柿，新鲜水果和牛皮癣之间存在反比关系。所有这些食物都含有健康的抗氧化剂。

Anotherstudy published a few years later发现牛皮癣患者的血液水平较低。

谷胱甘肽是一种强大的抗氧化剂，可在大蒜，洋葱，西兰花，羽衣甘蓝，羽衣甘蓝，卷心菜和花椰菜中发现。科学家推测，富含抗氧化剂的饮食可能会有所帮助。

Fish oil

根据Mayo Clinic，许多研究表明，鱼油可以改善牛皮癣的症状。

In a 1989 study , participants were put on a low-fat diet supplemented with fish oil for 4 months. Over half experienced moderate or excellent improvement in symptoms.

A1993 studyshowed that men who misused alcohol experienced little to no benefit from psoriasis treatments.

A 1990 study compared men with psoriasis to those without the disease. Men who drank about 43 grams of alcohol a day were more likely to have psoriasis, compared with men who drank only 21 grams a day.

Though we need more research on moderate alcohol consumption, cutting back may help ease psoriasis symptoms.

当前治疗focus on managing the symptoms of psoriasis, which tend to come and go.

Creams and ointments help reduce inflammation and skin cell turnover, reducing the appearance of patches. Light therapy has been found to help reduce flare-ups in some people.

For more severe cases, doctors may use medications that suppress the immune system, or block the action of specific immune cells.

However, medications can have side effects. If you’re looking for alternative treatments, some studies show promising results with certain types of diets.

Dermatologists have long recommended that a healthy diet is best for those with psoriasis. That means lots of fruits and vegetables, whole grains, and lean proteins.

此外，保持健康的体重可能会带来重大缓解。

A 2007 study 发现体重增加与牛皮癣之间有很强的联系。腰围，臀部周长和腰围比的腰围更高，也与患疾病的风险增加有关。

Try to eat healthy and keep your weight within a healthy range to help reduce psoriasis flare-ups.
