Although diet can not cause or cure rosacea, it is vital that rosacea sufferers are aware of certain foods which may improve their condition, and foods which may worsen it. Foods that are considered good for rosacea are generally foods which are considered good for the skin in general. These may include:

Fish including tuna and salmon
Berries - blueberries, strawberries, raspberries etc
Cucumber
Carrots

Some of the above may even cause a flare up for some people, so it is up to trial and error to work out which foods work for you. Foods such as berries contain antioxidants which are essential for good skin health. Try to eat as much high antioxidant food as possible, at the very least you will ensure that your underlying skin is in good condition which may lead to a reduction in rosacea symptoms.

What Not To Eat

Knowing what to eat is important, but knowing what you should not eat is perhaps of greater significance. Eating the wrong foods can cause rosacea to flare up uncontrollably for days on end. Not everyone will have the same trigger foods but patterns have emerged amongst certain types of foods which do seem to affect a large number of rosacea sufferers.
These include:

Chocolate
Tomatoes
Hot drinks
Peppers
Garlic
Wine or alcohol
Cheese
Citrus fruits
Avocadoes
Hot soup
Spinach
Figs
Red meat
Foods high in sugar

Foods or drinks that get the heart racing faster will never be ideal for rosacea sufferers. Alcohol is well known to increase the heart rate and even non-rosacea people can flush in the fact when drinking. High sugar foods can also elevate the heart rate and as such increase blood flow to the face, causing flushing. For this reason it is important to avoid that type of food as much as possible.

Rosacea can clearly have a drastic effect on diet and enjoyment of life when it comes to food. Many people find they simply can not visit a restaurant as there is nothing suitable to eat, and hot meals can cause major problems.

Until a cure is found for rosacea, try to stick to the foods you know do not cause you problems, and consider the sacrifices you are making to be good for your health; indeed most of the trigger foods are indeed quite unhealthy for you anyway. A positive mental attitude and a careful diet can help to manage your rosacea and prevent any major flare ups from occurring.
