Hi Rivka,and welcome to the forum.First thing,you are not alone.We all felt like that to start with.You have found a good place to get info on your diabetes.Have a good read round the forum and you will find a lot of advice.Did they give you a test meter? Many doctors/nurses are unwilling to give these out with a vague 'oh you don't need to test'.We say here,yes you do need to test so that you can find out which foods affect your blood sugar (BS) levels.You can buy the meters,they are fairly cheap,it's the test strips that are expensive!
Food...diabetes is an inability to metabolise glucose properly so any foods with sugars are best restricted.There are two main types of sugars,simple sugars such as sugar,these are quickly absorbed and send your blood sugar up quickly.The other main type are complex sugars/starches.These are absorbed more slowly but convert 100% into glucose so these should be restricted as well.The starchy carbs are found in bread,pasta,rice,potatoes and any flour based products.The standard NHS diabetic diet says eat these with every meal.Experienced diabetics have found that it is best to restrict these starchy carbs to keep their BS levels down.
When you look at food labels the label will say 'carbs of which x amount is sugar.Look at the whole carb content as it is the whole carb content that will affect your blood sugar.
It is very confusing to start with.Begin by cutting out all the obvious sugar in your diet.Restrict ,potatoes,rice and pasta etc to smaller portions than you now eat.You can eat plenty veg,meat,cheese etc.Fruit contains sugars as well,some can eat fruit some can't ,we are all different so it is very much trial and error till you find what works for you!!
I think that is enough to start with,please read round the forum and ask us questions,we've all been there and do understand just exactly how you are feeling.
