How To Control Blood Sugar After A High-protein Meal

What is the influence of dietary protein on post meal blood glucose? Does protein effect blood sugar after a meal? Is there additional math we need to do for improved control after meals? At present, those of us who use intensive insulin therapy understand how proper mealtime insulin dosing requires appropriate carbohydrate counting. This is based on the thought that carbohydrate is the main nutrient that influences our post meal blood sugar values. However, studies have demonstrated that protein and fat may also play a role in what happens to our post meal blood sugar. The impact of dietary protein on blood sugar has long been a topic of debate. Early research hypothesized that 100 g of ingested protein produced 50–80 g glucose. Later research showed, it was only ~ 10 g of glucose that showed up in the circulation following consumption of 50 g of protein (this is a serving of cooked meat about the size of a full outstretched woman’s hand). This equates to ~ 1 g of glucose produced from every 5 g of protein consumed. The results of the study below are consistent with this and, indicate consumption of ~ 75g and 100 g of protein ALONE may produce late rises in blood glucose which Continue reading >>

    A few months ago I had a test result of 104. Previously whenever I had it tested I was in the low to mid 90s. So I bought a test kit and got the following results: 2 hrs after dinner (pasta and bread) 136; bedtime 108; after overnight 8 hr fast 139.
    I am 48 with no family history of diabetes, only 5 lbs overweight. I do take Niaspan (timed release niacin), Zocor and Prevecit.
    I just increased the dosage of Niaspan a few months ago and wonder if thats causing the increase in glucose or if my numbers above are typical of someone who is prediabetic. Thanks.

    Yes it is possible for blood sugar to rise even though no food was eaten. Many diabetics will have a rise particularly in the early mornings due to what is known as the "dawn phenomenon". to explain it simply ,what happens is when blood sugar becomes very low the liver will kick in and produce glucose and cause readings in the early morn to be high. This does not happen to everyone but is common. If i eat nothing before bed ,my reading is high in the morning. However if I eat something such as a small apple my reading is better after sleeping. This is one of the reasons it's important to eat small meals regularly.It prevents spikes from too low to too high. Medication may help some but for me ,it actually works better if I eat something. I take meformin to control glucose which works great during the day but doesnt seem to help with first morning readings. You can get a lot of useful information from the diabetes education centers . If you havent already, contact the diabetes association and they will tell you where and when classes are held or contact them through a local hospital. The service they provide is invaluable. I am in Canada and this is a free service .
    Hope this helps...dont forget to ask your doctor about anything that concerns you Take care Mizzy

    Thanks Mizzy. Not what I wanted to hear since I was hoping it's the Niaspan but I appreciate your response. I guess I need to make a Drs appt. Is it not unusual for someone to go from normal levels to diabetic levels with out the pre-diabetic phase (I would assume the fasting levels being in the 130s makes me diabetic)?
