Normal Values For Blood Glucose

Blood Sugar Normal Values

Blood sugar fluctuations Blood sugar levels are tightly regulated by a variety of stimulations and mechanisms. This is important for metabolic homeostasis. Levels may fluctuate after fasting for long periods of time or an hour or two after consumption of food. Despite this, the fluctuations are minor. Normal human blood glucose levels remains within a remarkably narrow range. In most humans this varies from about 82 mg/dl to 110 mg/dl (4.4 to 6.1 mmol/l). The blood sugar levels rises to nearly 140 mg/dl (7.8 mmol/l) or a bit more in normal humans after a full meal. In humans normal blood glucose levels are around 90 mg/dl, equivalent to 5mM (mmol/l). Since the molecular weight of glucose, C6H12O6, is about 180 g/mol, when calculated the total amount of glucose normally in circulating human blood is around 3.3 to 7g (assuming an ordinary adult blood volume of 5 litres). In other words in a healthy adult male of 75 kg (165 lb) with a blood volume of 5 litres (1.3 gal), a blood glucose level of 100 mg/dl or 5.5 mmol/l means a total of about 5 g (0.2 oz or 0.002 gal, 1/500 of the total) of glucose in the blood. This also means approximately 45 g (1½ ounces) in the total body water. To Continue reading >>

    One of my major goals for doing Whole30 (which might actually turn into Whole60, Whole90 or WholeLIFE for me) is to get off of both Invokana and JanumetXR - which I am taking daily now.
    I started Day1 of my Whole30 yesterday. For the month prior, I had been doing a combination of Aktins (with some sugar free candy, Atkins shakes and PureProtein Bars as "treats") and Mediterranean Diet (no fruit, but lots of whole grains). My BC tests before breakfast averaged 95, and BC test 2 hours after dinner averaged 105 during the month of January.
    Yesterday I think I did pretty well on Whole 30 -
    Breakfast - Quiche (w/ lots of veggies (spinach, zucchini, onion, mushrooms) & ground turkey) and a bannana
    Lunch - Protein Salad (iceburg with grill chicken, hadboiled egg and Whole30 Ranch dressing - first time I ever made Mayo!!) and an Apple
    Dinner - Whole30 Classic Chili and Pineapple
    When I took my blood glucose test 2 hours after eating dinner last night my BC was 142 (the highest it's been since before Christmas). This morning when I woke up and checked BC it was 117 (again the highest it's been in over a month). Both of those readings are on the HIGH side.
    I'm thinking the fruit I ate yesterday caused the BC spikes. Since it's really the only thing I've added that I wasn't doing in January.
    So here's my questions ...
    1) Should I stop or reduce the amount of fruit I'm eating while on Whole30?
    2) Or are there fruits I should be avoiding - I'm thinking maybe the bannana, pineapple and apple have a high glycemic index??
    3) Does Whole30 look any different for Diabetics than everyone else?

    Banana and pineapple have some of the highest glycemic loads of all the fruits so they're not your best choice. It's also recommended that you eat UP TO 2 fist sized servings a day with meals... you've eaten it at three meals which isn't horrible but obviously probably not a good plan for your personal context. (note that 'up to' means that it's zero to 2... so you can eat zero fruit and it really shouldn't be pushing veggies off your plate)
    You really want to concentrate on the meal template and make your meals match. Your lunch is hard to tell how much you ate, but as far as veggies, you're woefully lacking.. iceberg lettuce is like eating hardened water... completely nutritionally void... you need to add other veggies... if you want salad, try darker greens and add some roasted or heartier veggies to it.
    Your dinner has no veggies other than what may be in the chili and that's negligible in a serving... you're looking for more like 3 cups of veggies per meal.
    As a diabetic, you definitely want to be working with your health care provider to monitor your condition... Whole30 can change what types and amounts of medications you are on and that's something that needs to be worked out one on one with your doctor.

    Just to be clear ... While I only said an iceburg lettuce protein salad for lunch Day1, there was also spinach, peppers (red, green, yellow & jalapeno), mushrooms and onions in there was well. Dinner Day1 also included plenty of Zucchini "noodles" cooked in with the Whole30 Classic Chili recipe. The fruit consumed during Day1 were not generous portions ... the apple was a "school box" sized apple, the pineapple chunks were measured as 1/2 cup, and the banana was on the small size.
    Day2 I reduced fruit consumption to 2 portions - 1/2 cup of strawberries w/ some added raspberries, and a small pear. Breakfast was leftover quiche w/ the strawberries/raspberries, lunch was grilled chicken raw peppers, broccoli and the pear, dinner was Chicken cacciattore w/ zucchini noodles. 2 hours after dinner, BC test was 151 (highest it's been in 2 months). Morning fasting BC on Day3 was 121 (highest it's been in the morning since mid-December).
    Day3 I reduced fruit consumption to 1 portion - 1/2 cup of cantaloupe chunks w/ breakfast. Breakfast was leftover quiche w/ cantaloupe, lunch was Whole30 Mexican Tuna salad on romaine leaves, raw peppers & roasted sweet potato, dinner was a palm sized piece of ribeye w/ asparagus. BC 2 hours after dinner was 121 (on the high side of normal, supposed to be under 130 two hours after dinner). This morning fasting BC was 117 (supposed to be under 100 before breakfast).
    I'm going to go without fruit today and see where I end up after dinner and tomorrow morning.
