Introduction
If the patient is in the remission phase of the disease, without obvious symptoms such as abdominal pain, diarrhea, or rectal bleeding, and has previously tolerated acidic fruits well, a small amount of fresh waxberry may be cautiously tried. Waxberries are rich in vitamin C, anthocyanins, and other antioxidant substances, which may benefit mucosal repair. It is recommended to choose fully ripe waxberries and closely monitor bowel responses; if no discomfort occurs, they may be consumed in a stepwise manner.
Generally, whether patients with ulcerative colitis can eat waxberries depends on the severity of their condition. The specific situations are as follows:
When ulcerative colitis is in remission, meaning symptoms are not obvious and intestinal inflammation has decreased, patients may consume waxberries in moderation. Waxberries are rich in vitamin C and fiber, and moderate consumption can help supplement nutrition and enhance immunity. However, it is important not to consume excessive amounts, as too much fiber may irritate the intestines and cause discomfort.
If a patient with ulcerative colitis is experiencing an acute flare-up, with obvious symptoms such as abdominal pain, diarrhea, and mucus or pus in the stool, eating waxberries is not recommended. The flesh of waxberries is relatively firm and contains a significant amount of dietary fiber and acidic substances, which may irritate the intestinal mucosa, worsening the inflammatory response and discomfort.
When selecting foods, patients with ulcerative colitis should follow the principles of easily digestible and low-fiber diets, and should pay attention to food hygiene, avoiding overly stimulating foods such as spicy or greasy dishes, to prevent additional strain on the intestines.
In daily life, patients are advised to keep a food diary under the guidance of a nutritionist and gradually develop a personalized dietary plan. During acute phases, priority should be given to warm, soft foods that are low in fiber and acidity. When trying new foods during the recovery phase, the principle of moderation should be followed.
