An immune system malfunction is the cause of ulcerative colitis, a persistent colon inflammation. The exact causes of this disease are not yet fully understood, but there are many factors that may play a role. This text discusses the possible causes of ulcerative colitis and the recommended diet for this disease.

Causes of Ulcerative Colitis

The exact causes of ulcerative colitis are unknown, but a combination of genetic, immunological, and environmental factors is thought to play a role. Risk factors include smoking, diet, and stress.

Inheritance

Heredity of ulcerative colitis is an important factor in the development of the disease. Studies have shown that people whose parents or siblings have ulcerative colitis have a higher risk of developing the disease themselves. There are several genes that have been linked to ulcerative colitis, but it is unclear how exactly they influence the development of the disease.

The immune system fails in ulcerative colitis

Ulcerative colitis is also called an autoimmune disease because the body’s own immune system mistakenly attacks its own intestines. It is believed that a malfunction of the immune system triggers the inflammatory reaction in the intestines that leads to the development of ulcerative colitis. However, the exact cause of this malfunction is unclear.

Inflammatory reactions

It is believed that certain inflammatory reactions in the intestine may contribute to the development of ulcerative colitis. These reactions can be triggered by a variety of factors, including infections, food intolerances, and environmental factors.

Nutrition for Ulcerative Colitis

Diet may play an important role in the development of ulcerative colitis. Some studies have shown that a Western diet high in fat, sugar, and processed foods is associated with an increased risk of developing ulcerative colitis (1).

Other studies have shown that a high-fiber diet with plenty of fruits, vegetables, and whole grains may reduce the risk of developing ulcerative colitis (2).

Smoke

Smoking is another factor that can affect the risk of developing ulcerative colitis. Studies have shown that smokers have a higher risk of developing ulcerative colitis than non-smokers. Even people who quit smoking have a higher risk of developing ulcerative colitis. (3)

Stress

Stress is another factor that can influence the development of ulcerative colitis. Studies have shown that people who suffer from chronic stress have a higher risk of developing ulcerative colitis than people who are less stressed. It is believed that stress affects the immune system and increases inflammatory reactions in the intestines.

Vitamin D deficiency and ulcerative colitis

A study has shown that vitamin D deficiency can increase the risk of developing ulcerative colitis. Adequate vitamin D intake could therefore help reduce or prevent flare-ups of ulcerative colitis.

Nuts protect against ulcerative colitis

There is evidence that regular consumption of walnuts may reduce the risk of ulcerative colitis. One study showed that people who ate at least 20–25 walnuts daily had a lower risk of developing the disease.
