What changes the calories
- Unsweetened soy milk has fewer calories than original or vanilla versions because it has no added sugar.
- Flavored varieties such as chocolate usually contain more sugar and therefore more calories than original.
- Brands differ in recipe and fortification, so the label on your carton may vary slightly from these values.
- Pouring by eye into cereal, coffee or smoothies often adds up to more than a measured cup.
Tips for logging it accurately
- Measure soy milk with a measuring cup or weigh it, especially when adding it to cereal or smoothies.
- Choose the entry that matches your carton: original, vanilla, unsweetened or flavored, since sugar content differs.
- In BerryFit, log soy milk as its own item in drinks and recipes so splashes in coffee are counted too.
