Most foods have percent of calories from fat listed on the nutrition label. I decided a list that shows percent calories from carbohydrates might come in handy for those who are controlling carbohydrates in their diet. This table was prepared using the USDA National Nutrient Database for Standard Reference - Release 18, available on the web. I downloaded the abbreviated spreadsheet and added a column to calculate percentage calories from carbohydrates, as ((gm carb - gm fiber)*4)/((gm carb - gm fiber)*4 + gm protein*4 + gm fat*9) * 100%
Listing over 7000 items, this table is pretty comprehensive - it includes raw caribou eye, for gosh sakes. Even so, it doesn't have values for some stuff I'd like to see - chutney, for example. The first few items claim to have negative percentage calories from carbohydrates. That is because the spreadsheet listed more grams of fiber than carbohydrate. In the case of the Chile con Carne W/ Beans, this is obviously an error. Or maybe these foods have some sort of non-carbohydrate fiber? Beans made of polyester? Beats me.
At any rate, I was surprised to discover several foods that I would have assumed would be safe for low-carb folks are actually loaded. Kraft Cheez-Whiz Lite, for example, has 29.80% calories from carbs, right up there with 29.88% for a Hershey's Pot Of Gold Almond Bar. Also, there are some overall low-calorie foods that, although they have miniscule carbs in an "average" serving, it'd be a low-carb disaster to gorge on them. For example, "BAMBOO SHOOTS, RAW" sounds innocent enough, but offers 47.80% cals from carbs, which is more than "DOMINO'S 14" Cheese Pizza, Ultimate Deep Dish Crust" at 47.73%. (So if you're going to eat 500 calories and your choices are a bucket full of raw bamboo shoots or a slice of deep-dish cheese pizza, you'll know what to do). Another shocker for me is "PEPPERS,JALAPENO,RAW", which weighs in at 53%. So although I'd have bet anything it'd be safe to munch on as many Jalapenos as you want, that ain't necessarily so. If you ate 10 big painyos, you'd be getting about 30 gm carbs.
Then there's low-carb beer (sigh). Turns out that although they offer low grams of carbs, as a percentage of calories, they're still surprisingly evil. Michelob Ultra, though it reminds me of water flavored with the backwash of someone who had just chugged a beer, nevertheless offers 81.11% of its few calories from carbohydrates. So beer != what's for dinner.
