    I am having difficulty to accurately measure the nutrition in foods that contain non-edible parts such as bones, like drumsticks or even corn on the cub.

    I don’t know whether the nutrition data stated on the product label is only for edible parts (i.e. bones don’t count). Because if it is in fact only for the edible parts, then how do I know how much of the weight stated on the package is edible? So if the package says 400g of drumsticks, how do I know how much of that is bone?

    Could someone tell me what the best way is to accurately track foods containing non-edible parts?

    Thank you.

    The data is for the edible portion only. So 400g is 400g of the edible portion.

    Best regards

    Yes, but how do I know how many grams of edible food the package contains?
    Because if the package says there’s 400g of drumsticks in it, then it includes the bone.
    If I weigh the bone after I eat the drumsticks, it’s still not accurate, because cooking the drumsticks changes the weight of the bone.
    I dissected the meat from the bone of many drumsticks and there’s still a big difference in the weight of bones of different drumsticks, as each drumstick differs in size.

    Has no one yet found a good way to track drumsticks in a simple way that doesn’t take a lot of time?

    Because how then are we supposed to track drumsticks or corn on the cub?

    For foods with refuse I tend to weigh them after they’re cooked and subtract the refuse weight. After a while, I tend to spot the trend and know more or less how many % is edible.

    Then again I don’t use sauce a lot, so if your dish is covered in it, I can see how it could be tricky. I’m also not too fussed if the numbers are a bit off. Ultimately the trend to me is more important than individual, absolute data.
