Is the new Coles low-carb bread type 1 diabetic friendly? Yes I think it is, read more below to discover why I think it is.

When trying anything new I always read the nutritional information on order to determine the impact it will have on my body. Certain high fat foods can cause insulin resistance and inflammation and will delay gastric emptying while protein will digest and get synthesised into carbohydrates.

Insulin Strategy

The strategy I used for this meal was based on the insulin type and macro composition. I injected for the carbs + (1/2 fibre) right before I ate as the Fiasp I use works almost immediately and so no pre-bolus was required. I then extended carbs at (protein*25%) + (fat *10%)

Goal:

The goal of any insulin strategy would be to inject enough insulin at the correct time so that the upward force the carbohydrates exert is counteracted by the downward force the insulin exerts and you stay in range for the duration of the meal.

To analyse this I use three (3) values, standard deviation, time in range (TIR) and Coefficient of the variation. These three (3) values will assist you in determining how good or bad a meal was for you in terms of blood sugar impact (BGI).

Time in Range (TIR): For TIR we are looking for a high percentage of your readings within a normal (I use 3.9-7.8 mmol/l ) range.

Standard Deviation: For standard deviation I look for values under 1 as a meal that has little to no blood glucose impact (BGI).

Coefficient of the variation (CV): Is the standard deviation divided by the average glucose. Its a measure that helps normalise the results by reducing the influence on average glucose. Most studies indicate that anything under 33% is good.

Results:

As we can see in the table below, the low-carb bread paired with the correct insulin strategy resulted in very stable blood sugars over a number of hours.

Time in Range (TIR): 100% (average)

Standard Deviation (SD): .5 (average)

Coefficient of the Variation (CV): 10% (average)
