Welcome Viv
You have a lot to learn as a newbie and once yyou know enough, you'll be able to make informed decisions for yourself.
However, it may help you to know that starch turns 100% to glucose in your body, whereas, for table sugar, it's only 50%. So if you want to keep your blood glucose down, without masses of medication It pays to minimise your starchy foods as well as your sugars.
Were you diagnosed Type 1 or tyoe 2? ther is information on this forum specific to either and then a lot of general stuff.
I'm terribly sorry that we can't really give you specific diet plans, because in the end, you have to find what suits you, your lifestyle and other circumstances.
However, we can say that meat, fish, cheese, and vegetarian protein sources, with plenty of fresh vegetables and some fruit are ideal.
Also, for most diabetics, fats are not an issue, so cream and butter are fine.
