Can anyone explain to me why, when I use a barcode to enter a food, the info about the number of calories is different when I look at the food in a list compared to when I look at the Nutritional Facts? For example, I have just added Sirena brand lite tuna. The serving size is 68g, and in the food list, it says that there are 356kj in 68g. But when I click on Nutrition Facts to get more info, it says that 68g contains 1813kj.
This same thing seems to happen for any food that I barcode.
