My psoriasis is quite bad at the moment. I think this may be due to me eating a fairly poor diet recently. During the last month I have been away from home a lot, eating a lot of restaurant meals or take-aways. This means I have been eating more fried food than normal, and hardly any fresh fruit and veg.

Over the next few weeks I will try to cut out various unhealthy or processed foods. We have stocked up on fruit and veg and healthy snacks, including nuts and dried fruit. I will try to avoid soft drinks and coffee, and stick to drinking tea.

I will probably allow 1 processed meal or take-away, but otherwise all of my hot meals will be home-cooked. Breakfast will be the usual bowl of cereal - we normally have low fat and low sugar cereals so that won't pose a problem.

I have stocked up on tins of mackerel because oily fish is supposed to be good if you have psoriasis. Lunch will probably alternate between fish and cottage cheese.

Daytime snacks used to include fruit with the occasional bag of crisps, cereal bar or biscuit. I will have to cut out the crisps and biscuits but I have stocked up on apples, bananas, dried apricots and dried figs. Sometimes I have a craving for carbohydrate and used to satisfy it with a biscuit. I will need to choose a healthier alternative, such as nuts.

I will give this diet a few weeks to see if it makes a difference. There are other foods such as wheat or yeast which can trigger psoriasis in some people, so I may eventually try to cut down on these, but I won't do that straight away. If I change too many things at once then I won't know which ones had an effect.
