Crohns Disease Foods
Although diet cannot cause or cure Crohns disease, some studies suggest that people who eat foods high in saturated fat and sugar or who eat processed foods may be more likely to develop the disease. Certain foods may also reduce symptoms and make recurrences of the disease less likely.
• Eating fruits and vegetables, lowering fat, and eliminating sugar may reduce the risk of developing Crohns disease. Although a low-fiber diet is one of the risk factors for developing Crohns disease, some people with Crohns disease find that fiber makes symptoms worse. If fiber bothers you, steam or bake your vegetables rather than eating them raw, and avoid high fiber fruits such as apples.
• Certain foods may aggravate symptoms of Crohns disease – most often, dairy products, fats, and spicy foods. People with Crohns disease may want to avoid these foods.
• Eat five or six small meals a day.
• If symptoms are severe, an elemental diet may be recommended. Elemental formulas are liquid diets that contain only the basic building blocks of food and need not be broken down into smaller substances along the digestive tract.
Some people find it difficult to stick to an elemental diet, but after a period of time, often other foods can be reintroduced. One study suggests that adding omega-3 fatty acids to an elemental diet may boost its nutritional content and make it more likely that people with Crohns disease will adhere to it.
Because of decreased appetite, malabsorption, chronic diarrhea, side effects of medication, and surgical removal of parts of the digestive tract, many people with Crohns disease have vitamin and mineral deficiencies. In particular, people with Crohns disease may lack adequate vitamin D, B12, and K, plus folic acid, calcium, and zinc. Your doctor may recommend that you take a multivitamin daily. Zinc (25 mg), folic acid (800 mcg), vitamin B12 (800 mcg) — These vitamins are used by the body to repair cells in the intestine.
In addition, drugs such as sulfasalazine and methotrexate may case levels of folic acid in the body to drop, requiring supplementation. Vitamin D (1,000 IU per day) — is necessary to maintain strong bones. People with Crohns disease, especially those who take corticosteroids, often have low levels of vitamin D and are at risk for osteoporosis. Fish oil (2.7 g per day) — Omega-3 fatty acids found in fish oil may help fight inflammation and reduce the chances of recurrence, but studies have been mixed. The study with the most positive results used a special type of fish oil – “enteric-coated free-fatty-acid form” – that is not sold commercially.
Some researchers suggest that measuring the blood levels of different types of fatty acids may help determine if fish oil would be useful. Do not take high doses of a fish oil supplement if you take blood-thinning medication.

Can Viagra Help Crohns Disease
While well known for its effect on blood flow, until now Viagra has not been used to boost circulation in the intestine. That could change with the finding that Viagra can help treat Crohns disease. People with the long-term, inflammatory condition develop holes and ulcers in the intestine.
A team from University College London wondered whether an overactive immune reaction was the problem.The team carried out biopsies on six Crohns disease patients and nine healthy volunteers. The operation triggered an acute immune response in the healthy people, producing white blood cells to heal damage caused by the removal of cells. But the Crohn’s patients responded by producing far lower amounts of white blood cells. The researchers used Viagra to boost blood flow to the intestine in the patients with Crohns disease, thus increasing the flow of white cells to the damaged area.
Researchers in the U.K. have a new theory to explain the cause of Crohns disease, and they say medications like the erectile dysfunction drug Viagra may prove useful for treating the bowel disorder if they are right.In Crohns disease, chronic inflammation causes ulcers within the digestive tract that can lead to severe gastrointestinal symptoms, including abdominal pain, persistent diarrhea, and rectal bleeding.The most widely accepted theory is that an overactive immune system causes the damaging inflammation.
But researchers from the University College London say the opposite appears to be true.They believe a weaker-than-normal immune response triggers the bowel inflammation that leads to Crohns disease. The researchers tested this theory by treating 10 Crohn’s patients with 50 milligrams of Viagra after injecting them with the killed gut bacteria. They found that blood flow to the infected area improved.
“Increasing blood flow is an important part of the inflammatory response, and that is why this drug may work,” Segal says. “But we don’t yet know if this will give rise to successful treatment. We need to study this further to find out.” The disease usually affects the small intestine and one in every thousand people in the UK is afflicted with this miserable complaint.
But now scientists believe they have found the cause of Crohns disease, and they think it could be treated with Viagra.The team of researchers from University College London say they believe the cause is the opposite of what has been supposed and is triggered by a weak immune system, rather than an overactive one where cells are attacked by the body’s own immune system.
Crohn’s was previously thought to be an auto-immune disease and was treated with immuno-suppressant drugs. But the researchers led by Anthony Segal and colleagues have discovered that people with Crohn’s have a weak and unresponsive immune system which does not repair damage easily. They say the flow of blood to damaged cells is substantially reduced, and a drug such as Viagra, best known for its effects on erectile dysfunction, could help the healing process as it stimulates blood flow.
Since it was identified in the 1920s there have been many theories as to the cause of Crohn’s and it was often compared with tuberculosis, but attempts to find an infectious agent have failed.
The research team compared the immune system response of Crohn’s patients and healthy individuals to minor injuries, such as skin abrasions and discovered a difference in the number of white blood cells called neutrophils produced by the body to heal the damage in the bowel and on the surface of the skin.
