Can dairy cause psoriasis

Can dairy allergy cause scalp psoriasis?

Dairy or milk-products are foods that are generally rich in calcium, vitamins, and protein. Milk and its products also tend to have high levels of fat and cholesterol, but there are low and fat-free variants that are also available on the market which provide healthier alternatives. Examples of dairy-containing products are: cheese, ice cream, yogurt, and milk. Although healthy in a balanced diet, some people are allergic to milk products and/or lactose intolerant. In people who are allergic to dairy, their immune system responds to the proteins found in milk, causing a release of histamines and resulting in rash, inflammation, and stomach pain. For people that are lactose intolerant, their bodies lack the enzyme lactase that is necessary to break down the sugar component of milk called lactose; resulting in stomach pain, gas, bloating, and diarrhea. Dairy also contains arachidonic acid and the protein casein, which contribute to many pro-inflammatory substances in the body. The higher the fat-content of milk, the higher amount of arachidonic acid it will contain.

For a person with psoriasis, it is recommended to limit or completely avoid any intake of milk and dairy products, even if the person is not lactose intolerant or allergic to milk. Dairy will not directly cause psoriasis, but it may make the symptoms of psoriasis worse and may trigger flare ups.
