Hi
@HSSS,
If I have interpreted your query correctly you are wondering why a breakfast of eggs only causes no BSL rise vs the occurrence of BSL rises with yoghurt or flaxmix taken separately.
I have not seen any direct data but assume that cooked eggs, containing no carbohydrate, could cause a flattish form of BSL rise in ? 3 hours or more (but not 2 hours) due to conversion of some protein to glucose. See optimisingnutrition.com glucogenesis
However, nutritional data from various internet sources quote yoghurt as containing perhaps 4 to 10 g of carbs per 100 g.
One would assume that such carbohydrate as lactose in yoghurt could raise BSL at the 2 hour mark.
Flaxmix contains 48.5 g per 100ml which again I assume would raise BSLs more sharply than protein.
