Calorie and protein disparities for the same foods
I had to log some smoked mackerel recently. I get this from an independent supplier in Scotland, who does not provide nutritional data. When trying to find what to log, I noticed large disparities between, for example, the NCCDB entry for smoked mackerel which cites 25.5 g protein and 199 kcal per 100g, and various UK supermarket entries in CRDB, which cite around 20 g protein and 300 kcal per 100g.
I'm not concerned about small discrepancies here and there, but for a food like this, where 100g or more could easily be an individual portion in a meal, choosing which entry to log will result in big differences that are important to me since I am trying to lose weight and preserve (hopefully even gain) muscle on a calorie allowance of 1400 per day, so calories and protein are the elements to which I pay most attention.
I have to say I am also exhausted by the effort needed to find data for foods from the UK. Even the names of basic foods are not present at times in the common foods search and I need to google a lot to try and find what it is called in the USA.
There is no point trying to track anything other than macros because the brand label entries in CRDB on which I have to rely in so many cases mostly do not give the extra data. Also, I am forced to use my phone to scan bar codes and then photograph the nutritional information on the pack for so many things because they are not present in the existing databases, which I find a stressful process. I far prefer to use Cronometer on my computer using a proper keyboard, mouse and 40" monitor rather than struggling with a phone. When weighing things in the kitchen, I write everything down on a piece of paper and then go to my study and enter them using my computer, because even the extra stair climbing involved in doing this is faster than struggling with the phone!
