Hmm
Thanks for the link.
I can't eat the portion sizes they suggest of apples, oranges or pears, without my BG spiking.
I've never tried 'black plums' assuming they are not talking about Victoria plums...?
Never tested a guava.
I would be ok with the berries and avocado.
So, practically speaking, my blood glucose meter contradicts about half the info, and supports the other half.
BUT the article makes some claims (guava leaf tea staves off the onset of diabetes, for example). But it gives no supporting evidence.
I would be very wary!
