Final answer:
Increasing fruit intake helps meet the DRIs for vitamin C and fiber, as fruits are rich in these nutrients, which support immune system health, skin health, and digestive health.
Step-by-step explanation:
If Yihan increases her fruit intake, she will be better able to meet the Dietary Reference Intakes (DRIs) for several important nutrients. Specifically, eating more fruits would help her reach her DRIs for vitamin C and fiber. Fruits are a good source of vitamin C, which is important for the immune system, skin health, and the absorption of iron. They are also high in dietary fiber, which can aid in digestion and help maintain a healthy weight. It is worth noting that fruits also contribute to the intake of other nutrients such as potassium and several B vitamins, including folate.
