First page of Plant-based diet mitigated the risk of chronic kidney disease in overweight individuals

Objectives Being overweight, with a body mass index >25, is associated with multiple comorbidities, including chronic kidney disease (CKD). A plant-based diet, such as a vegetarian or lacto-ovo vegetarian diet, serves as a preventive strategy for CKD in patients. We hypothesized that vegetarian diet lowers the occurrence of CKD in overweight subjects. Methods The retrospective study was performed in Taipei Tzu Chi Hospital by self-paid health-exam. Age younger than 40 years old and the subjects without sufficient biochemical or hematologic results were excluded. The incidence of CKD was evaluated according to the self-reported eating habits (vegetarians, lacto-ovo vegetarians, or omnivores), overweight(with a body mass index (BMI) ≥25 or higher abdominal circumference (>90 cm in male or >80 cm in female )) or not, or other biochemical or hematologic parameters. The interaction between different factors for the development of CKD were analyzed by Structural equation modeling. Results Among these 6,567 subjects, the subjects with lacto-ovo vegetarians had lower incidence of CKD than dietary habits as vegans and omnivores. The incidence of overweight was the highest in omnivore group. The lacto-ovo vegetarian group lower the risk of CKD occurrence than the omnivore group. After adjusting for age and sex in SEM model, the lacto-ovo diet lowered the risk for CKD from being with a high BMI or a higher triglyceride(TG)/high-density lipoprotein(HDL) ratio. Conclusion We concluded that lacto-ovo vegetarian dietary habits are associated with a lower occurrence of CKD in obese patients. The mitigating effect of the lacto-ovo vegetarian diet was due to the hazard of a higher BMI and TG/HDL ratio.
