Background

Evidence suggests adoption of a predominately whole food plant-based diet (WFPBD) may be beneficial in both hypertension and CKD. Our pilot trial previously showed that individuals with CKD 3 or 4 who attend an education program emphasizing the benefits of a WFPBD achieved a statistically significant decrease in weight, BMI, total, LDL, and HDL cholesterol levels and trended towards improvement in systolic blood pressure without a statistically significant increase in serum potassium. Here we report the changes in intake of vitamins and minerals during the intervention.

Methods

40 subjects with CKD 3 or 4, with hypertension but without proteinuria or hyperkalemia, were randomized to attend the education program (known as Jumpstart [JS]) or not. JS is a 15 day educational program designed to foster lifestyle changes including adoption of a WFPBD via a combination of lectures, support systems and food demonstrations. Individuals had food diaries done pre and post JS (or equivalent times for controls). We compared dietary intake of vitamins and minerals both within and between groups at the end of the trial.

Results

Compared to baseline, the intervention group showed significant increases in intake of vitamins A, C, and K, folate, magnesium, manganese, copper and oxalate, and significant decreases in the intake of vitamins B-12, D, and E, niacin. zinc, and selenium. Compared to the control group, the intervention group had significant increases in intake of vitamins A, C, and K, thiamine, folate, magnesium, manganese, and oxalate by the end of the trial. Significant decreases were seen in intake of vitamins B-12, D, and E, pantothenic acid, zinc and selenium. The intervention group also significantly reduced their added sugar consumption, glycemic index, and glycemic load compared to both baseline and with the control group at the end of the trial. Iron intake in the intervention group was not statistically different compared to either baseline values, or controls at the end of the trial.

Conclusion

Subjects with CKD 3 and 4 attending a 15-day education program emphasizing a WFPBD had significant changes in vitamin and mineral intake. Further studies are needed to determine the significance of these changes.
