Just got off the phone with the manufacturer of my whipping cream and they said it’s 3 g of carbs per 100 g of whipping cream. But whipping cream and water don’t weigh the same, so the standard conversion won’t work from the 15 ml serving size they list on the label.
So, I measured out exactly 100 g of the stuff on my digital kitchen scale and got about 1 T. shy of half a cup. Insert math and you get 0.428 g of carbs per tablespoon. Which doesn’t stack up with their “<1 g carb” label and the FDA guidelines.
So, I’m puttin’ it down to around 0.5 g of carbs per serving and calling it a day. Hopefully, the keto revolution will compel companies to list finer nutritional details on their labels in the future.
