Custard apple, also known as sugar apple or Annona squamosa, is a tropical fruit loved for its sweet taste, creamy texture, and rich nutritional value. Packed with vitamins C and B6, fiber, antioxidants, and essential minerals, it offers numerous health benefits, from boosting immunity to supporting digestion and heart health.

However, not everyone should enjoy this fruit. Experts warn that certain groups of people may experience negative side effects if they consume custard apples regularly:

1. People with diabetes – Custard apples contain natural sugars that can cause blood sugar spikes, making them unsuitable for those with poor glucose control.

2. Overweight or obese individuals – The fruit is calorie-dense and can contribute to weight gain if eaten in excess.

3. People with digestive issues – Its high fiber content may worsen bloating, diarrhea, or other gastrointestinal discomfort in sensitive individuals.

4. Individuals with kidney problems – Custard apple is rich in potassium, which may be harmful for those whose kidneys struggle to regulate mineral balance.

5. People allergic to Annonaceae fruits – Some individuals may develop allergic reactions such as itching, rashes, or difficulty breathing after eating custard apple.

While custard apple remains a delicious and highly nutritious tropical fruit, moderation and awareness are key. Those belonging to the groups above should be cautious—or avoid it altogether—to protect their health.
