The percentages listed in the food list are erroneous. The components that each food is comprised of are carb, fat and protein. The percentages of each of those components should all add up to a total of 100%. However, in this app, they do not. The totals for any given food are all over the place. For example, ARTIC CHAR RAW is listed as 0% carb, 8% fat and 20% fat. That only adds up to 28%!
If you click through to the item details, it indicates 0g carb, 7.9g fat, 19.9g protein, for total calories of 152. Rounding up, 8g fat x 9 calories per gram = 72 calories, and 20 grams protein x 4 calories per gram = 80 calories. 72 + 80 = 152 calories total. So the correct percentages for this item are: 0% carb, 47% fat, 53% protein, which correctly adds up to 100%.
This app is useless unless you want click through to the details for each item and do the math yourself.
