Hi Tina, welcome.
All you need to know to get this under control is within these threads! Carbohydrates are the beasties that cause our blood sugars to rise, in particular rice, pasta, potatoes and bread, although there are low carb breads available if you can’t bear the thought of giving it up, Livlife is around 4 carbs a slice, you can get it in Waitrose or Asda. Fruit is also high in natural sugar so be careful, especially the tropical ones. Some can tolerate a few strawberries or blueberries but testing your blood regularly is the best way to work out what foods are best for you and what to avoid. With veg, cauliflower, broccoli, cabbage, courgettes are good, root veg best avoided or kept to minimum. Peas are quite high as is sweet corn. All meat, eggs, bacon, mushrooms are great. Take some time to read as much as you can and then ask any questions you have, everyone is really friendly, we get it and all started where you are now
