Diabetic dietary changes

Hello,

Just found out that my dad in-law has 7.2 count blood sugar.

I would like to find out more about how he should change his diet, e.g. – white rice now what should he eat – etc… fruits can and cannot eat, beverages, replacement for sweets biscuits   etc… he loves those.

In his morning cereals he usually uses sugar – what can he use now – Honey?

We also saw on Google – 5 foods one should not eat – but the sites do not open – so still not sure what one should and should not eat as far as that is concerned –

Your reply is much appreciated,

Antonella
