Can you eat too much star fruit?

How do you know if star fruit is bad?

Choose a ripe star fruit

A ripe star fruit will be firm to the touch, have a bright yellow color, and may have slightly browned edges. Occasional patches of green are okay, but if a star fruit is mostly green in color, it means it's not ripe.
