What should be the healthiest fruit?

It is possible to argue for a long time about which fruits are the most useful for the body, but it can be unequivocally argued that fruits will benefit health only if they meet the following criteria:

full maturation;
the presence of a dense, intact, clean peel;
the presence of juicy pulp (loose pulp is a sign that there are almost no vitamins left in the fruit).

When choosing fruits, it is important to pay attention to their appearance: the integrity of the skin, smell, density, absence of spots, dents, rot.
