Milk products have a low glycaemic index (GI) but a high insulinaemic index (II), meaning they elicit an insulin response similar to white bread despite low blood glucose impact.
Be aware that while milk has a low glycaemic index, it can still stimulate a significant insulin response. This is due to milk proteins, not lactose. For most people, this is not a concern, but those monitoring insulin levels should be aware of this discrepancy.
ModerateQualifiesMEDIUM confidence
Consequently, milk products elicited elevated IIs, indistinguishable from a white bread reference meal, despite GIs in the lower range.
Why this rating
Based on unpublished results cited in the paper, requiring further validation.

- Adopting a low glycaemic index (GI) diet improves metabolic parameters in individuals with insulin resistance or type 2 diabetes, including lowered HbA1c, improved glucose tolerance, and reduced insulin resistance.Good
- Low-GI breakfasts can produce a 'second-meal effect' that significantly reduces post-prandial glycaemia and insulinaemia at a subsequent lunch, provided the breakfast induces a prolonged absorptive phase.Good

- Initial treatment for type 2 diabetes should be a combination of metformin and either an SGLT-2 inhibitor or a GLP-1 receptor agonist to achieve cardiorenal protection, rather than monotherapy or older agents like sulfonylureas.Strong
