The daily intake of fresh fruit varies according to age, and generally the younger the age, the lower the intake.

The intake of children aged 7-10 is 150-200g/day, about 1 smaller apple weight; 4. The intake of children and adolescents aged 11-14 is 200-300g/day, about 1 ordinary apple weight; 5. The intake of adolescents aged 14-17 is 300-350g/day, about 1 half apple weight; 6. The intake of adults aged 18 and above is 200 -350g/day, about 2 apples in weight; 7. 200-300g/day for elderly people over 65 years old.
