At first glance, this seems reasonable, but closer examination reveals flaws.
First, many so-called "nutritional supplements" are merely foods, health foods, or health products (some lacking approval numbers altogether). Their nutritional value is limited, and they possess no therapeutic effects—at best, they are simply food items.
Second, even for nutritional foods, their properties must align with the nature of the illness to be beneficial. For example, heat-type illnesses require cooling or neutral foods, while cold-type illnesses require warming foods; otherwise, the condition may worsen. Additionally, certain components or additives in foods are unsuitable for colitis patients.Milk components, for instance, are unsuitable for many colitis patients, often triggering or worsening flare-ups. Preservatives—especially those frequently exceeding safe limits—can cause harm to the body, potentially posing greater risks to colitis sufferers.
Third, chronic colitis patients experience weakened digestive and absorptive functions. Excessive food intake and "nutritional supplements" cannot be fully digested or absorbed, instead increasing the burden on the intestines and stomach and aggravating the condition.
Doctors have observed that some colitis patients experience increased flatulence. Reducing meal portions significantly decreases flatulence, while slightly increasing intake noticeably increases it. This flatulence serves as an indicator of gastrointestinal overload.Therefore, colitis patients must avoid indiscriminate supplementation and overeating. Instead, they should moderately reduce food intake, generally eating until about 80% full—ensuring that reduced portions do not lead to weight loss and maintain good energy levels.
