The effect of acorn muffin consumption on glycemic indices and lipid profile in type 2 diabetic patients: A randomized double‐blind placebo‐controlled clinical trial

Acorn is a nutritious fruit with the reported potential of ameliorating diseases, including diabetes. This research aimed to assess the effects of acorn muffin consumption on glycemic, lipid indices, and appetite in patients with type 2 diabetes. Sixty‐six subjects were dichotomized to receive either one muffin containing 10 grams of acorn flour or a placebo muffin containing white wheat flour (no bran), per day, for 8 weeks. Acorn muffin consumption improved glycated hemoglobin (p = .06, mean difference [MD] = −0.65), triglyceride (p = .06, MD = −36.38), and high‐density lipoprotein (p = .05, MD = 1.30), albeit only marginally significantly. Among appetite parameters, hunger, desire to eat, and prospective to eat were significantly lower, and satiety and fullness were significantly higher, in the acorn muffin group. In conclusion, acorn muffins could be utilized as an adjuvant therapy to control appetite and ameliorate glycated hemoglobin in patients with type 2 diabetes. However, further investigations are required for a more comprehensive conclusion.
