Make it easier for yourself and others when logging new food items. Make sure to indicate serving size in title and use this secret to make calculating serving info easy!
Food info is most often per 100g, which is also often not the serving size. Calculate how many serving are in 100g (eg: chocolate squares) and put that number instead of one next to serving when logging in a new food and enter the info given for 100g. Tracking = select 1 serving for correct info.
