Tamarillo basics & common questions

What is a tamarillo?

A tamarillo (Solanum betaceum) is a small, oval, tree-grown fruit often called a tree tomato. The smooth skin can be red, orange, or yellow, while the inside holds firm, tangy flesh and soft, seed-filled pulp.

Tips, cautions & common mistakes

Practical tips

• Ignoring individual needs: If you have kidney disease or need to limit potassium, speak with your clinician or dietitian before adding several servings of tamarillo or other high-potassium foods.
• Assuming lab results equal human outcomes: Many promising findings come from lab and animal studies; human data are more limited, so expectations should stay realisticNational Library of Medicine – Tamarillo antioxidant potential.
• Adding lots of sugar: Turning tamarillo into very sugary jams or desserts may cancel out some of the heart-conscious benefits.
