Yes, white flour, sugar, pasta. I am gluten free so.. no wheat. We eat pasta with other grains, just not a lot of it. I don't eat bread, even gluten free.
Fruit and veg. have good carbs. If you are diabetic you need to be more careful with what kinds you eat. Some are better to eat that others, lower glycemic index. I love coconut palm sugar for that reason. I can add a bit of that to tea etc.
Our brain needs carbs every day, but not the one that spike sugar. Eating them with protein and fiber is important also.
Before I drink my smoothie every day, I drink some water with apple cider vinegar. Good for keeping glucose even.
Good carbs are unprocessed. Beans, legumes, nut and seeds etc.
I love using coconut manna and coconut oil. I missed chocolate candy so now I make it with dark choc, coconut manna or oil and a drop of peppermint oil. AMAZING and healthful.
