Psoriasis - Causes, Prevention and Helpful Diets

Psoriasis is a recurring autoimmune disorder that affects more than 7.5 million Americans.

It tends to appear pink or red, usually with silvery-white scales, on those with fair to light skin tones. It may look salmon-coloured with a silvery-white scale on medium skin tones, and on darker skin tones, it could look violet and the scale grey. Or it can also appear dark brown and difficult to see.

Like other autoinflammatory diseases, psoriasis occurs when your immune system — which commonly attacks infectious germs — begins to attack healthy cells instead.

3 Causes of Psoriasis


Stress is a major trigger for some people with psoriasis, either causing psoriasis to flare up for the first time or to make it worse after you’ve been diagnosed.

“Psoriasis is very stress-dependent. It flares very easily when patients are under stress, and it tends to improve when they’re relaxed,” says Vesna Petronic-Rosic, MD, a dermatologist and associate professor of medicine at the University of Chicago Medicine in Illinois. Stress management techniques, such as exercise, yoga, and meditation, may help manage psoriasis symptoms.

Dry Skin 

Anything that injures the skin can cause a psoriasis flare, including excessively dry skin.

The solution: Keep your skin moisturized.

Upper Respiratory Infections 

Colds and other infections, activate the immune system and can cause psoriasis to flare. If you have psoriasis and develop a sore throat, get it treated instantly. Long-term antibiotics may be an option for someone who has psoriasis and frequent sore throats.

3 Common Ways to Prevent Psoriasis

Take dietary supplements

Dietary supplements may help ease psoriasis symptoms from the inside.

Fish oil, Vitamin D, Milk thistle, Aloe Vera, Oregon grape, and evening primrose oil have all been reported to help ease mild symptoms of psoriasis, according to the National Psoriasis Foundation.

Check with your doctor before taking supplements to make sure they don’t interfere with other health conditions you may have or medications you’re taking.

Soak your body

A lukewarm bath with Epsom salt, mineral oil, milk, or olive oil can soothe the itching and infiltrate scales and plaques. Oatmeal baths can also be very helpful and soothing for plaque psoriasis.

Be sure that the water is not hot. Hot water can cause more irritation. Moisturize immediately after your bath for double benefits.

Prevent dry skin

Use a humidifier to keep the air in your home or office moist. This can help prevent dry skin before it starts.

Moisturizers for sensitive skin can keep your skin supple and moisturized.

Healthy Diets That Can Help Deter Psoriasis

In general, having a balanced whole-food diet is the best approach to reducing inflammation throughout the body. It reduces psoriasis flare-ups and makes your symptoms less severe. Following a Mediterranean diet for psoriasis can also reduce chronic inflammation that contributes to heart disease, type 2 diabetes, cancer and other conditions.

The best foods if you have psoriasis include:

  • Fish, lean protein or plant-based proteins such as tofu or tempeh
  • Fruits and vegetables
  • Legumes (beans and lentils)
  • Nuts and seeds
  • Olive oil
  • Small amounts of low-fat dairy
  • Whole grains

There isn’t a single answer for keeping the symptoms of psoriasis at bay. What works for one person may not work for another.

Some treatment options may have negative side effects for preexisting conditions other than psoriasis.

While these remedies for psoriasis may help with mild cases, prescription therapy is required for more severe cases. Talk to your doctor before seeking treatment on your own.
