Introduction

Eating sweet potatoes continuously for a month may have various effects, including supplementing dietary fiber, improving intestinal function, aiding blood sugar control, increasing vitamin intake, and potentially causing gastrointestinal discomfort. These effects depend on the amount consumed and individual differences. If persistent symptoms such as bloating, acid reflux, or abnormal blood glucose fluctuations occur, medical advice should be sought promptly. Sweet potatoes are rich in dietary fiber, and regular consumption can increase daily fiber intake.

Consuming sweet potatoes continuously for a month may lead to various effects, including increased dietary fiber intake, improved intestinal function, better blood sugar control, enhanced vitamin intake, or gastrointestinal discomfort. These outcomes depend on the amount consumed and individual differences. If persistent bloating, acid reflux, or abnormal blood glucose fluctuations occur, medical advice should be sought promptly.

1. Supplementing dietary fiber: Sweet potatoes are rich in dietary fiber. Eating them regularly can increase daily fiber intake, help slow down post-meal blood sugar spikes, and provide nourishment for gut microbiota, thus maintaining a balanced intestinal microecosystem.

2. Improving intestinal function: Dietary fiber promotes intestinal motility. Continuous consumption over a month may alleviate constipation caused by insufficient fiber intake, leading to more regular bowel movements. However, adequate water intake is necessary to achieve optimal results.

3. Assisting blood sugar control: Sweet potatoes have a lower glycemic index than refined grains such as white rice and flour. When used as a partial substitute for staple foods, they reduce intake of refined carbohydrates and may aid in blood sugar management. However, consuming large amounts additionally may instead raise blood glucose levels.

4. Increasing vitamin intake: Sweet potatoes contain β-carotene (which can be converted into vitamin A) and vitamin C. Regular consumption helps supplement these vitamins, supporting skin health, protecting vision, and enhancing the body's antioxidant capacity.

5. Causing gastrointestinal discomfort: Sweet potatoes contain gas-producing enzymes. Excessive intake or rapid consumption can easily produce gas in the digestive tract, leading to bloating, belching, and acid reflux. These symptoms are particularly noticeable in individuals with weak gastrointestinal function.

When consuming sweet potatoes, portion control is important—recommended daily intake is 50–100 grams, replacing part of the staple food. Preferred cooking methods include steaming or boiling; frying should be avoided. Combining sweet potatoes with protein sources and vegetables helps maintain a balanced diet and reduces the risk of gastrointestinal discomfort.

Can patients with intestinal obstruction eat sweet potatoes?

If intestinal obstruction has entered the remission phase after treatment, and the patient has resumed passing gas and bowel movements with disappearance of symptoms such as abdominal distension and pain, and intestinal motility is gradually returning to normal, a small amount of steamed sweet potato may be consumed. Sweet potatoes are rich in dietary fiber, which can promote intestinal motility, but intake should be limited (e.g., a small piece), and the patient should monitor for any bloating or abdominal pain after consumption to avoid increasing the burden on the intestines.
