Yes, there’s a bunch of BS going on with peanuts… I googled “what percentage of peanuts is carbohydrates?” and looked at the first ten websites that gave actual broken-down numbers. There definitely is a range of figures, and looks like there is a good bit of copying information back-and-forth.
Net Carbohydrates % by weight or grams per 100 grams:
Raw: (decently consistent)
7.8
7.6
7.6
7.6
7.6
7.0
Oil Roasted:
5.9
5.9
Dry Roasted:
14.3 (Keebler)
13.4
13.4
10.6 (Planter’s)
One of the websites mentioned that it’s figures came from the USDA National Nutrient Database for Standard Reference, Release 23.
I looked at the USDA’s current statistics, and after the protein and fat content is given, it says, “Carbohydrate, by difference,” and the results look suspiciously high to me - I think this is where those higher carb numbers for dry-roasted peanuts are coming from. The math may not be working out right, or at least not consistently. Or is it that there may be hidden carbs in there?
Among the “dry-roasted” at the USDA site, looking at the Keebler statistics, total carbs is suspiciously exactly the same as protein, and the information comes from the manufacturer.
Ingredients: PEANUTS, CONTAINS LESS THAN 2% OF: SEA SALT, SUGAR, CORN STARCH, CORN SYRUP SOLIDS, TORULA YEAST, SPICES (CONTAINS CELERY), PAPRIKA, DRIED ONION, DRIED GARLIC, NATURAL FLAVOR, MALTODEXTRIN. Date Available: 07/14/2017 Date Last Updated by Company: 07/14/2017
While there may be less than 2% of sugar, corn starch, corn syrup solids and maltodextrin, those four together may be bumping up the dietary carb content substantially.
