Seasonal Variations in Nutrient Composition of Selected Fruits and Their Implications for Type 2 Diabetic Management.

Fruits play a key role in type 2 diabetes management but seasonal changes can affect their nutrient profile and glycemic impact. This study examined the composition of selected tropical fruits across rainy and dry seasons in Ibadan, Nigeria, to assess implications for diabetes care. Fresh fruit samples were randomly purchased from Oje Market, Ibadan, during both rainy and dry seasons. Fruits were washed, peeled, homogenized, and analyzed in triplicates. Proximate composition was determined using standard AOAC methods. Reducing sugars were quantified by colorimetric methods. Vitamin C was measured by titration with 2,6-dichlorophenolindophenol, while B-vitamins and folate were determined spectrophotometrically.
