The blue skin of grapefruit is edible, and the "green skin" of grapefruit is not completely immature. For example, green pomelo imported from Japan, Israel and other places has a blue skin. Foreign pomelos are generally very small, and the specifications are about 7 or 8, while domestic pomelos are mostly about 2 kg to 2.5 kg, which can be easily distinguished by size alone. Don't worry, wait until the late-maturing grapefruit comes down.

Blue grapefruit is one of the foods often encountered in reality. Only by correctly understanding food can we better absorb the nutritional value of food and realize the effects they bring. But if the variety of food is different from the nature of the food you usually eat, you can still eat it normally. Foods in different States need to be understood before they can be eaten normally, because only in this way can they absorb nutrients.
