Cardiorenal Protective Diet (CPD)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.

Brief Summary:
This study will evaluate providing fruits and vegetables in a sustainable community care clinic setting, in addition to routine medical care, to individuals with CKD (Stage 2-4) on CKD and CVD risk, or cardio-renal risk factors. Further, metabolomics profiling will be used to study how change in the diet affects disease risk. Data from this study will be published in peer-reviewed journals, presented at national conferences, and will serve as pilot data to guide and strengthen applications for NIH funding.

Arm Intervention/treatment
Experimental: Fruits and Vegetables
This group will receive a prescribed amount of free fruits and vegetables (F&V) for 6 weeks of pick-up at a farm stand or direct delivery. After 6 weekly pick-up/deliveries, participants will be provided vouchers and reminders to obtain F&V at farm stands for an additional 6 weeks with minimal contact.
Other: Fruits and Vegetables
Fruits and Vegetable delivery, once a week for 12 weeks.

No Intervention: Wait List Control
This group will not receive a prescribed amount of free fruits and vegetables (F&V) for 12 weeks. They will serve as the control group. After 12 weeks of control and data comparisons, they will be given 12 weeks of vouchers with minimal contact.

Primary Outcome Measures :
  1. Changes from baseline in fruit and vegetable intake at 6 weeks and 3 months. [ Time Frame: Baseline; 6 weeks and 3 months ]
    Track changes in fruit and vegetable intake via ASA24 dietary recall food diary.

  2. Changes from baseline in systolic and diastolic blood pressure at 6 weeks and 3 months. [ Time Frame: Baseline; 6 weeks and 3 months ]
    Measure changes in systolic/diastolic blood pressure (mmHg) to assess cardiovascular disease (CVD) risk.

  3. Change from baseline of urine albumin-to-creatinine ration (ACR) at 6 weeks and 3 months. [ Time Frame: Baseline; 6 weeks and 3 months ]
    Measure of renal damage.

Secondary Outcome Measures :
  1. Metabolomics will be used to profile how changes in diet effects disease risk. [ Time Frame: Baseline and 6 Weeks ]
    Urine and plasma specimens will be collected for metabolomic analysis as novel biomarkers may appear in both sample types.
