Comparison of monounsaturated vs polyunsaturated fats for diabetes
Monounsatur
Fat Basics
MUFAs have one double bond (e.g., oleic acid in olive oil); PUFAs have multiple (e.g., omega-3/6 in fish/nuts). Both replace saturated fats to boost HDL and lower triglycerides in type 2 diabetes.
Glycemic Control Comparison
High-MUFA diets reduce fasting glucose (-0.57 mmol/L vs carbs, -0.87 mmol/L vs PUFA) and body weight (-1.56 kg), with moderate HbA1c drops. PUFAs (esp. linoleic acid 18:2) cut prediabetes/T2D risk 26-66% via anti-inflammation but show less direct glucose-lowering vs MUFAs in meta-analyses.
Heart and Inflammation Effects
MUFAs raise HDL (+0.06 mmol/L) and lower systolic BP (-2.31 mmHg), protecting diabetic hearts. PUFAs excel in reducing CVD via omega-3s but may increase oxidation if unbalanced (high omega-6).
Indian Diet Sources
-
MUFA: Mustard oil (35%), groundnuts, ghee in moderation, sesame.
Usage Tips
Aim 20-35% total fat: 15-20% MUFA for stable glucose; add PUFA (5-10%) for inflammation. Use olive/mustard oil for sabzi, nuts (20g/day) pre-meals. Monitor CGM; combine with fiber-rich dals.
