Oranges: Who Should Avoid This Vitamin C Powerhouse?

• Individuals with chronic kidney disease (CKD) should avoid oranges due to high potassium content, which can lead to hyperkalemia and life-threatening heart problems.
• People with acid reflux or GERD should limit or avoid oranges as their high citric acid content can worsen heartburn, discomfort, and sour burps.
• While oranges contain fiber, excessive consumption without sufficient water can worsen constipation by hardening stool.
• Those prone to heartburn should consume oranges in moderation as they can relax the esophageal sphincter, causing stomach acid to flow back.
• People with citrus allergies should avoid oranges, as proteins like Cit s 1 and Cit s 2 can cause symptoms ranging from itching and rashes to severe breathing difficulties.

Why It Matters: Despite being rich in Vitamin C, oranges can be harmful for individuals with kidney issues, acid reflux, or citrus allergies.
