Well, exotic is a subjective adjective and so what I think is exotic might not be to you. Therefore, I'm just going to be listing some fruits that are high in Vitamin C. Papayas are rich in Vitamin C, along with antioxidants which can aid digestion. Bananas are also rich in Vitamin C, along with other vitamins and minerals such as Vitamins A, B, and potassium. They also include an amino acid that can improve your overall mood. Pineapples are dripping with Vitamin C and other enzymes that will help with your digestion - specifically, in digesting protein. Finally, jackfruits are rich in Vitamins A and C, along with potassium, magnesium, and calcium.
