Passionfruit Overview

Passionfruit is a tropical fruit with a fragrant aroma, tart-sweet flavor, and crunchy edible seeds. It contains natural sugars and carbohydrates and is not suitable for keto in meaningful amounts. For diabetic-friendly plans, small portions may work due to fiber content, but portion control matters.
