Dairy Products can Aggravate Psoriasis Symptoms

Removing milk and other commercially produced dairy products from the diet has often caused a dramatic improvement in eczema and psoriasis in children as well as adults.


Many psoriasis patients have found that as long as they stay completely away from dairy products their symptoms disappear, but if they eat any dairy the psoriasis scales pain return. Many people have spent so much money and time trying to get their psoriasis condition under control only to find it was something so simple.

Many people have suffered from psoriasis for years and no medicine and cream given to them by their dermatologist has helped them, but when they gave up dairy products their psoriasis symptoms started disappearing almost immediately.

Why do dairy products contribute to psoriasis?

1. Lactose intolerance

Milk is a known allergen. It is a well-known fact that, over seventy percent of the world’s population cannot properly digest cows milk due to lactose intolerance, (a deficiency of the enzyme lactase necessary for milk digestion).

Many people don’t have sufficient amounts of the lactase enzyme, which is needed to properly digest the lactose found in milk. Products such as yogurt, hard cheese, and butter, are usually much better tolerated due to their lower lactose content.

This being the case, milk consumption will for allergic individuals cause an almost immediate outbreak of psoriasis lesions. [The protein in cow's milk frequently is only partly digested and becomes a major source of intestinal putrefaction and toxemia. Incompletely digested protein may pass the wall of the small intestine and cause allergy].

2. Casein allergy

If a glass of milk or a slice of pizza precipitates a runny nose, itchy skin, swollen lips, or other symptoms, you may have an allergy to casein, a protein in milk. Another milk protein associated with allergies is whey. Some people are allergic to both casein and whey.

A casein allergy occurs when your body’s immune system mistakenly thinks the protein is harmful and produces antibodies for protection. This triggers the release of body chemicals such as histamine that cause psoriasis and eczema symptoms.

Allergies to a specific protein, casein, which is found in high quantities in milk, is actually quite common in the general population, in which lactose intolerance is low relative to other populations.

An allergy is defined as an inappropriate immune response by the body to a non-harmful substance, and manifestation of casein allergies can range from full blown anaphylactic shock to chronic, low-grade irritation.


Many people feel that psoriasis can be aggravated by their allergies.  This is thought to be caused by delayed hypersensitivity mechanisms. So it stands to reason that an unidentified casein allergy may be causing aggravation of psoriasis symptoms.

Dairy allergy is different than an intolerance to dairy, also known as lactose intolerance. A lactose intolerance is the inability to digest the milk sugar called lactose. Quite different than being allergic to the proteins in dairy products. Additionally, an intolerance happens in the digestive system and a dairy allergy happens in the bloodstream.

Most people with these allergies develop them when they are infants and outgrow them as they get older. However, some people do not outgrow them and continue to be allergic as adults. It is unusual to develop an allergy to milk proteins later in life.

Unfortunately, many medical doctors ignore the importance of diet when treating chronic problems and disease. A food trial is an excellent and easy tool to use to determine if and what foods may be exacerbating your psoriasis. Of course, eliminating milk won’t work for everyone, since some people may not have a casein allergy. But it definitely is worth a try!.

3. Digestive disorders

Many psoriasis patients suffer from digestive disorders, and milk products are known to be prime causes of digestive problems due to their high mucous content.

If you are absolutely certain that you are not in any way allergic to dairy products, then you can consume small amounts of commercially produced low fat dairy products: such as; low fat milk [2%, 1% milk, or skim milk], yogurt, cheddar cheese, and unsalted butter.

Dairy alternatives

1. Soy milk

Soy milk is now available in most supermarkets. It can be used in exactly the same way as cow’s milk. Some soy milk is fortified with calcium, so try to use this type. Other ‘milks’, made from rice or oats, are now available; some of these are also fortified with calcium.

2. Goat’s milk products

goatienAn excellent alternative to standard cows milk products is Goat’s Milk.

Many people, who suffer from digestive disorders, and/or lactose intolerance including those who suffer from psoriasis, find that they can much better tolerate goat’s milk.

  • The protein chains in Goats milk are shorter so it sits in the intestines for much less time. In contrast, cow’s milk will take much longer to digest.
  • The smaller molecules of goat’s milk are closer in size and composition to human milk, making it much easier to digest.
  • Goat’s milk protein is substantially less allergenic than cow’s milk protein in susceptible individuals.

Goat’s milk is a very good source of calcium, riboflavin, and biotin, and a good source of protein, pantothenic acid, vitamin D, and potassium.

Fresh and powdered goat’s milk and goat’s cheese is available in many fine health food stores, and online from the following firms: Coonridge Organic Dairy Inc. And Redwoodhill Farm Inc.

A highly recommended dried Goats milk product is Goatien produced by Garden Of Life USA Inc. This product is made from goats that are fed only natural feed, and are free of all growth hormones. Goatien is a rich source of protein, nutrients, and enzymes.
