Crohn’s disease is a chronic inflammatory bowel disease that affects the lining of the digestive tract. It causes inflammation of your digestive tract, which can lead to abdominal pain, severe diarrhoea, fatigue, weight loss and malnutrition. Inflammation caused by Crohn's disease can involve different areas of the digestive tract in different people. Studies have shown that diets comprising fruits, vegetables, legumes, and whole grains can help prevent and treat diabetes, heart disease, some cancers, high blood pressure, and other long-term conditions. The man in the recent study was 25 years of age when he received a diagnosis of Crohn's disease. This had followed several years of experiencing symptoms such as bloating, bouts of abdominal pain, fatigue, ulcers, and nausea. After receiving intravenous infusions of infliximab every 8 weeks for 1 year, the symptoms lessened but the man did not "achieve clinical remission." Tests revealed "mildly clinically active disease," and he continued to experience bouts of abdominal pain, bloating, and fatigue. During his second year of using the medication, the man gave up eating animal and processed foods for 40 days for religious reasons. While he was following a plant based diet, "he experienced a complete resolution of symptoms." The man was then able to come off his medications completely. That was in August 2017, and the authors note that he has reported "no relapses since." "This case study supports the idea that food really is medicine.", says Dr. Hana Kahleova.
