Thanks so much for posting such well-written info! I appreciate it b/c it resonates with what I learned about nutrition (i'm in vet school so i had my share of biochemistry and nutrition in my undergrad education), but you explain it very well. I've been trying to tell people that the main thing is calories in vs. calories out but they never believe me. Now i'm armed with knowledge! Thanks.
My question is about nutrition labels. You and Keta have touched on it in this thread. For example, this one bar (Strive bar) has, according to the label, 190 calories, 8 g fat, 25 g carbs (no fiber, no sugar, only 22 g other carbs), 20 g protein. I have no idea where they got 190 calories from. (25x4 + 20x4 + 8x9 = 252)
What's going on with these labels? How do these alcohols act in the body and should they be counted as carbs? I would expect they'd be converted to glucose, but maybe not. I know the federal laws require labels to be within 20% of the calorie count, so I'd expect manufacturers to fudge the numbers a litte, but this is just odd.
Another odd thing is that in my animal nutrition classes where formulating diets for "food animals" was very specific, we learned that protein actually has 5.5 cal/gram, carbs have about 4.5 and fat has 9.5. Ever run across this in academic literature? Wonder why the USDA figures it with 4, 4, and 9.
Thanks for your time!
