Generally speaking, the nutritional value of pineapple includes vitamin C, potassium, bromelain, dietary fiber, and sugars. Contraindications include avoiding consumption by individuals with allergies, not eating on an empty stomach, caution for patients with gastrointestinal diseases, individuals with oral ulcers, and limiting intake for patients with high blood sugar.

Nutritional Value

1. Vitamin C: Pineapple is rich in vitamin C, which has antioxidant properties that help remove free radicals and protect cells from oxidative damage.

2. Potassium: The potassium in pineapple helps regulate osmotic pressure inside and outside of cells, ensuring normal cell shape and function.

3. Bromelain: Bromelain can break down proteins, aiding the body in digesting and absorbing proteins.

4. Dietary Fiber: The dietary fiber in pineapple can promote gastrointestinal motility, helping to prevent or improve constipation.

5. Sugars: The sugars in pineapple mainly consist of glucose, fructose, and sucrose. These sugars provide energy for the body, meeting the demands of daily activities and metabolism.

Contraindications

1. Avoid for Allergic Individuals: Pineapple contains bromelain, and allergic individuals may experience allergic reactions such as skin itching, red rashes, and respiratory swelling after consumption.

2. Not Suitable for Consumption on an Empty Stomach: Pineapple contains a significant amount of acidic substances, such as citric acid and malic acid. When consumed on an empty stomach, these acids can directly irritate the gastric mucosa, leading to excessive secretion of gastric acid.

3. Caution for Patients with Gastrointestinal Diseases: The acidic substances in pineapple can irritate ulcer sites, causing pain and bleeding, while bromelain may damage the protective barrier of the gastric mucosa, increasing the burden on the gastrointestinal tract.

4. Caution for Patients with Oral Ulcers: The oral mucosa of patients with oral ulcers is already damaged. The acidic substances and bromelain in pineapple may irritate the ulcerated area, worsening pain and delaying the healing of oral ulcers.

5. Limited Consumption for Patients with High Blood Sugar: Patients with high blood sugar should limit pineapple consumption, as pineapple contains relatively high levels of sugar, which may affect blood sugar control if consumed in excess.

When consuming pineapple, it is important to control the quantity to avoid excessive intake that may lead to adverse bodily reactions such as abdominal pain, diarrhea, and other gastrointestinal discomforts.
