Key lime pie can offer several benefits, primarily stemming from its key ingredient, limes. Limes are a good source of vitamin C, which supports the immune system, skin health, and wound healing. Additionally, the pie's combination of sweet and tangy flavors can provide a satisfying dessert experience. However, key lime pie recipes typically include ingredients like condensed milk and pie crust, which can be high in sugar and calories. Enjoying it in moderation and opting for healthier ingredient choices when possible can help maximize its benefits.
