Recommendations Summary

PDM: Vegetable-Based Protein and Prevention of Type 2 Diabetes 2014

Click here to see the explanation of recommendation ratings (Strong, Fair, Weak, Consensus, Insufficient Evidence) and labels (Imperative or Conditional). To see more detail on the evidence from which the following recommendations were drawn, use the hyperlinks in the Supporting Evidence Section below.


  • Recommendation(s)

    PDM: Vegetable-Based Protein and Prevention of Type 2 Diabetes

    If the consumption of vegetable-based protein is proposed for the prevention of type 2 diabetes, the registered dietitian nutritionist (RDN) should advise individuals who are at high risk for type 2 diabetes that the source of dietary protein alone, without weight loss, may or may not be beneficial. There were no studies identified to evaluate the impact of vegetable-based protein intake vs. animal-based protein intake, independent of weight loss, on outcomes in adults with metabolic syndrome or individuals with prediabetes.

     

    Rating: Insufficient Evidence
    Conditional

    • Risks/Harms of Implementing This Recommendation

      None.

    • Conditions of Application

      • This recommendation applies when the consumption of vegetable-based protein is proposed for the prevention of type 2 diabetes
      • Research on synergistic effects of nutrients was not evaluated.

    • Potential Costs Associated with Application

      The costs of medical nutrition therapy (MNT).

    • Recommendation Narrative

      No studies were included in the evidence analysis for this recommendation.

      In Adults with Metabolic Syndrome

      • Glycemic-related outcomes (FBG, random BG, two-hour post-prandial BG, A1C):
        • There were no studies identified to evaluate the impact of vegetable-based protein vs. animal-based protein on glycemic-related outcomes in adults with metabolic syndrome
        • Intervention studies are needed to ascertain the effects of vegetable-based protein vs. animal-based protein on glycemic-related outcomes in adults with metabolic syndrome with or without meeting the metabolic syndrome criteria for impaired glucose tolerance and impaired fasting glucose.
      • Lipid outcomes (TG, HDL):
        • There were no studies identified to evaluate the impact of vegetable-based protein vs. animal-based protein on lipid outcomes in adults with metabolic syndrome
        • Intervention studies are needed to ascertain the effects of vegetable-based protein vs. animal-based protein on lipid outcomes in adults with metabolic syndrome with or without meeting the metabolic syndrome criteria for lipid levels.
      • Anthropometric outcomes (WC, WHR):
        • There were no studies identified to evaluate the impact of vegetable-based protein vs. animal-based protein on anthropometric outcomes in adults with metabolic syndrome
        • Intervention studies are needed to ascertain the effects of vegetable-based protein versus animal-based protein on anthropometric outcomes in adults with metabolic syndrome with or without meeting the metabolic syndrome criteria for anthropometric measures.
      • Blood pressure outcomes:
        • There were no studies identified to evaluate the impact of vegetable-based protein vs. animal-based protein on blood pressure in adults with metabolic syndrome
        • Intervention studies are needed to ascertain the effects of vegetable-based protein vs. animal-based protein on blood pressure in adults with metabolic syndrome with or without meeting the metabolic syndrome criteria for blood pressure.
      • Renal outcomes:
        • There were no studies identified to evaluate the impact of vegetable-based protein vs. animal-based protein on renal outcomes in adults with metabolic syndrome
        • Intervention studies are needed to ascertain an effect of vegetable-based protein vs. animal-based protein on renal outcomes in adults with metabolic syndrome with or without meeting the metabolic syndrome criteria for urinary albumin excretion rate or albumin:creatinine ratio.

      In Individuals with Prediabetes
