hi Mari,
I made up a Custom entry for my coffee and cream combo. I use a 10 oz mug, and measure exactly 1/2 Tbsp (7 ml) 18% cream. I use no sweetener. I figured out the carbs for 10 oz of just plain coffee separately, then worked out for the cream, added the two together, then entered the combined values as a custom food. Do it once, it saves it for you, so you just click on your Custom list whenever you have that again. I do this for my lowcarb recipes too.
It would be nice if you could use real cream, it's so much lower in carbs, but I realize you're kinda up there in never-never land! Might be hard to get.
And yes, the carbs in coffee add up (0.12 carbs per fl oz --- not a big deal if you only have one sip, but two or three mugfulls can indeed rack up 4 or 5 carbs) But not 4 carbs per cup?? that sounds a bit high. Coffeemate is made with corn syrup solids, so ya, it adds up too. Here's the data, for one level tsp (5 ml) 10 calories, 1 gm carb, 0.6 gm fat, 0 protein. The "light" coffeemate is 2 carbs per level tsp. (less fat, more corn syrup)
hope this helps,
Doreen
Added Note
Mari, I checked the counts for Carnation evaporated milk, full fat (not the 2%) ... for a whole Tbsp (15 ml) it counts 1.58 gm carbs, 1.19 gm fat and 1 gm protein. Since you're using 1-1/2 tsp coffeemate, why not substitute 1-1/2 tsp of the carnation?? That's equivalent to 1/2 Tbsp, so the carb count would drop to 0.79 per serving. And it's a bit higher in fat, so would make your coffee nice and creamy. Plus, the cans keep forever on your shelf. Anyway, just a suggestion, real cream still is best..
