Star Fruit

Pineapple
Pineapple is the safer and more nutritionally potent choice for most people, though Star Fruit is an excellent low-sugar alternative if your kidneys are perfectly healthy.
Pineapple scores higher due to its broad safety profile, digestive enzymes, and richer mineral content. Star Fruit scores respectably for low sugar and calories but is heavily penalized for its severe kidney risk and lower overall nutrient density.
You trade Star Fruit's low sugar and calorie count for Pineapple's superior digestion benefits, higher vitamins, and guaranteed kidney safety.
