Ok, first, you understand I am not a doctor but I have lived with diabetes for over 10 years and diabetes runs in my family. I will tell you from my personal experience that eating that many carbs (45 to 60) will definitely keep your blood sugar high all day and give you high fasting. Please read this link. It's from the website that's also in my signature. https://www.bloodsugar101.com/what-is-a-normal-blood-sugar
In order to get blood sugar down to real normal levels, we cannot eat 45 to 60 grams of carbs a day. Eating like that will keep blood sugar very high and necessitate different diabetes meds. My suggestion is to cut way down on those carbs: cut down on bread and don't eat cereal or crackers, anything made with flour. Potatoes will keep blood sugar very high, too. By cutting back on carbs, you will also lower your triglycerides and cholesterol.
I don't know why your bp is that high. I do know that steady exercise like walking, swimming, using an exercise bike, etc. can help bring bp down. Also, be aware that processed food has a lot of salt already. Anxiety and physical pain can also raise bp - I know this from my own personal experience. Losing weight (if you are overweight) will bring down both your bp and your blood sugar but I don't know if you are overweight.
I will tell you that if you do change what your eating, you need to test your blood sugar more often. If you cut back on carbs, you will definitely not need as many diabetes meds but this is something you need to talk to your doctor about
. For your information, we do not need to eat bread products or potatoes for nutrition or energy. We can get plenty of nutrition and energy from fresh vegetables and other food.
I hope you have a wonderful Christmas!
