What changes the calories
- Roasting in oil adds the calories of the oil that clings to the nuts, while dry roasting changes the calories only slightly.
- Salted, honey-roasted or chocolate-coated hazelnuts carry extra calories from sugar, coatings or added fat.
- Because hazelnuts are small and calorie-dense, eating from the bag instead of a measured portion can easily double or triple a serving.
- Chopped hazelnuts pack differently than whole ones, so a cup of chopped and a cup of whole nuts weigh different amounts and have different calories.
Tips for logging it accurately
- Weigh hazelnuts on a kitchen scale rather than estimating by handfuls, since a few extra nuts add up quickly.
- Log the form you actually ate, and add any oil, salt coating, sugar or chocolate separately if your entry is for plain nuts.
- In BerryFit, save your usual hazelnut portion by weight so you can log snacks and toppings in seconds.
