Introduction
In general, individuals with diabetes, impaired digestive function, kidney disease, corn allergy, or hypothyroidism should avoid drinking corn juice. In addition, corn juice should be consumed in moderation, and healthy individuals should opt for freshly prepared corn juice. If discomfort occurs after consumption, intake should be stopped immediately, and medical attention should be sought if necessary based on individual circumstances.

Generally, corn juice is not recommended for people with diabetes, those with weak digestive function, patients with kidney disease, individuals allergic to corn, and patients with hypothyroidism. The specific reasons are as follows:

1. Diabetic Patients

Corn juice contains a high amount of carbohydrates, which can be rapidly broken down into glucose after consumption, leading to a sharp rise in blood sugar levels within a short time. Drinking corn juice increases the difficulty of blood sugar control and may worsen the condition; therefore, it is not recommended.

2. Individuals with Weak Digestive Function

Corn juice contains a significant amount of dietary fiber. For individuals with insufficient digestive enzyme secretion or slow gastrointestinal motility, it is difficult to fully digest and absorb. Consumption may lead to indigestion symptoms such as bloating, abdominal pain, and belching, so it should be avoided.

3. Patients with Kidney Disease

Corn juice contains a certain amount of protein and phosphorus. Patients with kidney disease already have impaired kidney function and reduced ability to excrete metabolic waste. Excessive intake of protein and phosphorus increases the filtration burden on the kidneys, potentially worsening renal function and destabilizing the condition.

4. Individuals Allergic to Corn

Corn is a common allergen. In individuals allergic to corn, drinking corn juice can trigger an abnormal immune response. Symptoms may include skin itching, rashes, diarrhea, and difficulty breathing. In severe cases, it may even threaten health, so consumption must be strictly prohibited.

5. Patients with Hypothyroidism

Corn contains small amounts of goitrogenic substances that can interfere with thyroid hormone synthesis. Since patients with hypothyroidism already have insufficient thyroid hormone production, consuming corn juice may exacerbate thyroid dysfunction and hinder recovery, making it unsuitable for consumption.

In addition, corn juice should be consumed in moderation. Healthy individuals should opt for freshly prepared corn juice. If discomfort occurs after drinking, consumption should be stopped immediately, and medical attention should be considered based on individual circumstances.
