TRYING to work out what your blood sugar levels will be after dinner? Soon there will be an app for that.
Columbia University researchers have developed a personalised algorithm for an app to make meal planning easier for people with type 2 diabetes.
The algorithm works by using a technique called data assimilation, a mathematical model commonly used in weather forecasting.
Users enter fingerstick blood measurements and a photo of a particular meal into the app, called Glucoracle, along with a rough estimate of the meal's nutritional content. After a week, the app begins generating predictions based on the information it has learnt.
"While we know the general effect of different types of food on blood glucose, the detailed effects can vary widely from one person to another and for the same person over time," said the study's lead author David Albers.
"Even with expert guidance, it's difficult for people to understand the true impact of their dietary choices, particularly on a meal-to-meal basis.
"Our algorithm, integrated into an easy-to-use app, predicts the consequences for eating a specific meal before the food is eaten, allowing individuals to make better nutritional choices during mealtime."
Dr Albers expects the app could be ready for widespread use within two years.
