Extremely accurate. Here’s how it works: First, our nutrition experts collected almost 100,000 foods with known added sugar values. Then, our Data Science team used that info to train our artificial intelligence model so that it could accurately predict how much added sugar is in a food by looking at all the other nutrients. The WW AI model understands these complex relationships between nutrients in a food and uses this information to assign a Points value to a food even when we don’t know the exact amount of added sugar. The value is then double checked by our team of nutritionists and food data experts for an added layer of accuracy.
