Vegetable Intake, but Not Fruit Intake Is Inversely Associated With Fasting Plasma Glucose in Kidney Transplant...

Area of Science:

• Nephrology
• Endocrinology
• Nutritional Science

Background:

• Glycemic control is crucial in type 2 diabetes, but its dietary links are understudied in kidney transplant recipients (KTRs).
• Understanding dietary impacts on KTRs' health is vital for long-term graft and patient outcomes.

Purpose of the Study:

• To investigate the association between dietary intake, specifically fruits and vegetables, and glycemic control in kidney transplant recipients.
• To determine if vegetable or fruit consumption impacts fasting plasma glucose levels in this population.

Main Methods:

• An observational study included 263 adult KTRs with functioning allografts for over 1 year.
• Dietary intake was assessed using food frequency questionnaires.
• Linear regression analyses examined the relationship between fruit/vegetable intake and fasting plasma glucose.

Main Results:

• Average vegetable and fruit intake was 238.24 g/d and 511.94 g/d, respectively.
• Fasting plasma glucose averaged 5.15 ± 0.95 mmol/L.
• Increased vegetable intake showed a significant inverse association with fasting plasma glucose (adjusted R² = 0.203, P < .001), with each 100g increase correlating to an 11.6% reduction.

Conclusions:

• Vegetable consumption, not fruit consumption, is inversely associated with fasting plasma glucose levels in kidney transplant recipients.
• Dietary vegetable intake may play a key role in improving glycemic control in KTRs.
• Findings suggest a potential dietary intervention strategy for KTRs.
