Psoriasis Diet

foods to avoid with psoriasis diet planPsoriasis is a condition which can, in some cases, be tricky to manage. It is likely that if you are suffering from psoriasis, you are taking certain medications to help ease your symptoms. This will be coupled with you trying to avoid your triggers (these will be different for everybody). On top of this, we suggest that you give a lot of thought to the psoriasis diet. It is not a rigid diet plan. It is more a collection of tips for ensuring that you eat well. If you follow the advice on this page, then we are positive that you can keep most of your psoriasis flare-ups at bay.

Lose Weight

Honestly, this is one of the best things you can do. If you actively try to lose weight, you will be well on your way to following the psoriasis diet anyway. Studies seem to suggest that those who are overweight have a much greater chance of suffering from a psoriasis flare-up. When those flare-ups do appear, they tend to be a lot worse too.

There are plenty of guides to losing weight out there, so we are not going to cover this part in too much depth.


This needs to be taken out of the equation. When you drink alcohol, it has an impact on the blood vessels in your skin. It, essentially, opens them up. The T cells, which are responsible for psoriasis, are able to get into them far, far easier. This means that you are more likely to suffer from a flare-up.

It doesn’t even take that much alcohol for this effect to happen. Even if you are a light drinker, you may see that your symptoms occur more frequently.

Junk food

Junk food is high in saturated and trans fats. On top of this, there are a lot of processed sugars. It is not good for you. The main reason junk food is not good for you is down to the fact that all of those things we have mentioned already tend to promote inflammation in the body. Since psoriasis is just inflammation, this is something you will want to avoid.

Of course, once you start cutting out that junk food, you are going to lose weight naturally anyway, which is always going to be a plus. Remember, weight loss is most of what you are going to need to do when it comes to losing weight on the psoriasis diet.

Red Meat

Next up on our list of items that you really want to eliminate from your diet if you are suffering from psoriasis is red meat. Now, there is fat in this which you already know is bad. The worse thing about red meat, however, is arachidonic acid. This is a fat which can make your psoriasis a lot worse. While all saturated fats are bad, this one is easily converted by the body into something which can cause inflammation. So, sorry, if you are suffering from psoriasis then you will need to cut bacon out of your life.

Dairy Products

Again, these contain arachidonic acid. When most people talk about dairy products, they think about milk and the like. We also want to throw egg yolks into the mix too as they are high in the same acid.

The main dairy product you will want to avoid, however, is cow’s milk. This is because it includes casein which has the potential to cause inflammation in the body. In fact, it promotes inflammation even in those who are not suffering from psoriasis in the first place (a different type of inflammation)

Nightshade Plants

Nightshade plants include:

  • Peppers
  • White potatoes
  • Eggplant
  • Tomatoes

The reason for this is because these plants contain something known as solanine. This is a chemical compound. In some people, this can trigger pain. Of course, pain is linked to inflammation. Most people who attempt to follow a psoriasis diet discover that they can eliminate the vast majority of their symptoms if they just eradicate nightshade from their diet.

Citrus Fruits

These fruits include:

  • Grapefruit
  • Oranges
  • Lemons
  • Limes

Anything made from these fruits (including fruit juices) should be eliminated from your diet. They are no good for you at all and can cause inflammation. They are not even that good for your skin, despite what some people may tell you. There are other ways in which you can get the vitamins and nutrients that these provide into your diet.


Many people have an intolerance to gluten. So, cut back on those grains. This means minimal rye, barely, and wheat.

There was a study carried out in Portugal which discovered that psoriasis symptoms in people with a sensitivity to gluten cleared up very quickly after they stopped consuming it. Even if you are not sensitive to gluten, you may as well give up on the stuff anyway, it does not really have that much benefit. Any benefit that it does bring to the table can be obtained in other ways.

Spicy Foods

Finally; some people have discovered that spicy foods can increase inflammation in their body. If you love your spicy foods, then you do not have to eliminate them completely from your life, but do try to cut back on them as much as possible. We promise you; you are going to end up being far, far healthier this way!

It is probably worth noting at this point that there is no 100% conclusive evidence which shows that psoriasis and your diet are linked. There is a lot of evidence, but much of it has not come under a formal study. However, do not let that put you off following a psoriasis diet plan. Most people who do follow the plan discover that their symptoms are eradicated, and we are positive that you will end up feeling the same way too. It really is going to be worth going down this route. We promise you! Remember; keep an eye out for other things that may be triggering you too.
