Can sweet corn be consumed as a staple food over a long period?

Generally speaking, sweet corn is not recommended as a staple food for long-term consumption. The detailed explanation is as follows:

Although sweet corn contains abundant vitamins, dietary fiber, and minerals such as potassium and manganese, its carbohydrate content is relatively high, and it lacks certain essential amino acids and fatty acids that the human body requires. Long-term consumption of sweet corn as a staple food may lead to nutritional imbalance and subsequently affect health.

Sweet corn contains a certain amount of sugar. Although it has a relatively low glycemic index and is considered a low-GI food, excessive consumption may still cause elevated blood sugar levels. Particularly for individuals with diabetes or metabolic abnormalities, long-term excessive intake of sweet corn may worsen their condition. At the same time, sweet corn contains a high level of dietary fiber, and moderate consumption can help promote gastrointestinal motility and relieve constipation. However, excessive intake may lead to indigestion, bloating, or other gastrointestinal discomforts. Individuals with weak digestion may experience gastroesophageal reflux when lying down at night if they consume too much sweet corn for dinner.

To maintain nutritional balance and good health, it is recommended to have a diversified diet and consume various foods in appropriate amounts, such as lettuce, apples, eggs, etc. Additionally, dietary structure and intake should be reasonably planned based on individual health conditions and needs.
