Glycaemic and insulinemic response to dietary carbohydrates in horses.

Abstract: Dietary sugar and starch affect plasma glucose and insulin concentrations. Little information is available about the effect of dietary fibre on plasma glucose and insulin concentration. It is hypothesized that different dietary fibre compositions will alter post-prandial glycaemic- and insulinemic index of test meals. The objective was to measure postprandial glucose and insulin concentrations in horses fed meals of different fibre compositions. Methods: Blood was drawn via jugular vein puncture and the glycaemic and insulinemic index were calculated. Results: The meal effect on glycaemic and insulinemic response followed the expected pattern, where plasma concentrations increased after feeding and declined after peak concentration. Glycaemic index was 100 (H), 102 (OB), 102 (BB) and 106 (M) and did not differ significantly between meals. Insulinemic index was 100 (H), 140 (OB), 121 (BB) and 125 (M) and did not differ significantly between meals. Conclusions: In conclusion, meals containing different fibre compositions did not affect the glycaemic- and insulinemic index in horses.

The research examines how different dietary fibres affect glucose and insulin levels in horses’ blood after a meal. Despite variations in fibre composition, the study found no significant difference in the glycaemic and insulinemic indexes.

Study Objective and Hypothesis

  • The primary goal of this study was to determine how different fibre compositions in meals affect the post-meal (postprandial) concentrations of glucose and insulin in horses.
  • The researchers hypothesized that various dietary fibre compositions would change the glycaemic (related to glucose in the blood) and insulinemic (related to insulin) indexes of the meals tested.

Methodology

  • The researchers conducted blood tests using jugular vein puncture in horses after they consumed meals of varying fibre compositions.
  • The study then computed the glycaemic and insulinemic indexes from these blood samples.

Results

  • The influence of the meals on the glycaemic and insulinemic responses followed the predicted pattern: plasma concentrations increased after feeding the horses and fell after peaking.
  • The glycaemic indexes for the different meals tested did not exhibit significant differences. The values were 100 for the Hay (H) meal, 102 for the Oat Bran (OB) meal, 102 for the Beet Bran (BB) meal, and 106 for the Mix (M) meal.
  • Similarly, there was no significant difference in the insulinemic indexes across the varied meals. The values were 100 for the Hay (H) meal, 140 for the Oat Bran (OB) meal, 121 for the Beet Bran (BB), and 125 for the Mix (M) meal.

Conclusion

  • The study concluded that horses’ post-meal glycaemic and insulinemic responses did not significantly differ when they consumed meals that contained diverse fibre compositions.
  • This finding suggests that different dietary fibre types do not significantly alter glucose and insulin levels in horses’ blood post-meal.
