What is the blood sugar sensor for?
Your blood sugar sensor automatically checks your blood sugar levels every 15 minutes to give an accurate picture of your blood sugar responses. Your responses will be compared to thousands of other people who joined our PREDICT studies or purchased the product, and ate the exact same muffins under the same conditions. This allows us to measure your blood sugar control in a standardized way. The blood sugar sensor gives us a precise picture of your blood sugar curves for all meals, and helps us gives you a more accurate assessment of your blood sugar.
Blood sugar is important, but only one part of the story
Your blood sugar responses are important to personalizing your recommendations, but they are not the only measure that is taken into account. Here's why:
1. There is more to your biology than only blood sugar
While keeping your spikes and dips to a minimum is important, there is more to your nutritional health than just your blood sugar control. Your blood sugar control alone does not take into account how a food may impact your blood fat levels or your gut health. This is why our scores combine all these factors to give you recommendations that take into account these other aspects of your biology.
2. A lot of factors influence your blood sugar response
Let's pretend this was your blood sugar response to a simple sandwich.
Now look at what happens to your blood sugar response to the exact same meal if you did some exercise after eating.
Your curve would become smaller as exercise, or activity in general, can blunt your blood sugar responses.
Now let's see what happens if you slept badly the night before.
Your curve is likely to be larger as bad sleep can cause your blood sugar levels to spike.
What about if you ate the same meal, but you also ate something else just before it?
Your sandwich (second meal) would cause a bigger spike in your blood sugar compared to if you ate it while you were fasted. Your previous meals can impact your blood sugar response.
For all these reasons, your blood sugar measurements to the meals you log may not give the whole picture. That's why we use your standardized muffin test to help predict your responses to all foods, even those you didn't test.
How is your blood sugar data used?
Individual responses to food are affected by many factors, as shown above. For these reasons, we predict your blood sugar response to a meal by taking into account your overall blood sugar responses from the testing period, use the nutritional characteristics of the meal, and we do not include in the prediction the effects of other factors that may affect it (such as your sleep, exercise, previous meals etc).
In order to give you the most accurate prediction and score to the meals you logged during the testing period, although we do take into account your overall blood sugar responses during the testing period, we do not yet adjust our predictions to the specific observed responses to each meal during testing, because responses may have been affected by the many factors described above.
As more and more people participate in our studies and product, we expect to be able to use this data to untangle more of this complexity and further improve and personalize our predictions for you to all meals, as well as those you logged, and include in our predictions the effects of factors such as sleep and exercise.
