Rosacea is a chronic, lifelong skin condition that (mostly) affects the face. The disease is common: approximately 1 in 20 Americans have rosacea. Women are affected more often in the early stages (flushing and erythrosis), but more men reach the advanced stage, and rhinophyma occurs almost exclusively in men over 40 years of age.

Rosacea is characterized by various skin areas. Disorders and sufferers must suffer from reddening of the skin, erythrosis (reddish or purple discoloration of the skin), telangiectasia (permanent enlargement of small blood vessels), papulopustular rosacea (papules are small, red, raised bumps; Pustules are similar, but contain pus). or rhinophyma (enlarged, red, swollen nose) and some of these signs and symptoms are very common in many people; About 94% of people with rosacea have a conditioner. These attacks last from a few minutes to several hours, and the redness seen in rosacea is inherently temporary. The disease is more or less progressive and the more pronounced skin lesions usually follow sporadic flushing.

The exact cause of rosacea has not been determined, but here are many theories. Sun exposure can be a factor, and sun exposure can trigger acute flushing episodes. Another possible cause are skin mites, Demodex folliculorum and Demodex brevis. These tiny insects usually live at the base of hair follicles. They are often found on the faces of people with rosacea, and it has been suspected that they can trigger an inflammatory response (inflammation widens blood vessels, which contributes to flushing, and can also damage blood vessels and permanently damage them). . Infection with the widespread Helicobacter pylori bacterium was also suggested as the cause. There can also be genetic defects in the vascular system of the skin that cause the hem to expand easily and permanently.

The signs and symptoms of rosacea are not dangerous, but can be disagreeable, unsightly, and discomforting. (However, rosacea can affect the eyes. Approximately 3% to 58% of patients with skin changes have eye problems and rosacea keratitis can cause blindness.) Although there is no cure for rosacea, the disease can be treated. Topical medication, oral medication, and laser therapy can be used to control the blush and remove some blemishes, swollen blood vessels, and discoloration. However, it would be far preferable to prevent flush outbreaks and the development of erythrosis and papulopustular lesions. It is known that certain factors – sunlight, stress, heat – can cause signs and symptoms of rosacea, and food has been identified as the cause.

What foods have been considered as causes of rosacea signs and symptoms? The list is long and there are obviously individual differences in sensitivity: high doses of B6 and B12, chocolate, tomatoes, hot drinks, hot sausage, red pepper, black pepper, vinegar, bell pepper, white pepper, garlic, wine, schnapps, beer , Cheese, yoghurt, sour cream, milk, citrus, eggplant, avocados, spinach, raisins, figs, bananas and marinated meat.

Why do these foods make rosacea worse? Nobody knows exactly, and given the fact that the exact cause of rosacea has not been clearly identified, it is not surprising. However, a look at the pathophysiology of rosacea can provide some clues.

The flush that is so common in people with roseacea is caused by the dilation of the small blood vessels on the face. Why this happens is not certain. The blood vessels can be genetically weak or damaged by years of sun exposure. There may also be an increase in the number of blood vessels or damage to the walls of the blood vessels. Regardless of the cause, the blood vessels expand (which are very close to the surface on the face). Many of the foods that trigger flushing attacks are most likely to increase this by increasing body temperature. In order to lose body heat, the blood vessels dilate. Others can cause a flush by stimulating the release of histamine. This is a naturally occurring substance that affects blood vessels and some foods, e.g. Beer and citrus fruits can stimulate the release of histamine.
