The coffee question, answered: each tablespoon adds about 20 calories. On the energy-density scale, 131 kcal per 100 g puts half and half at the moderate end.
A typical serving (1 tbsp, 15 g) has about 20 calories, and 100 g has 131 kcal. Calories scale with weight, so double the portion means double the number.
There are 3.1 g of protein in 100 g of half and half, which works out to about 0.5 g per serving (1 tbsp). Treat it as an energy source rather than a protein source.
Yes, in the plain arithmetic sense: 11.5 g of fat per 100 g supplies about 79% of the calories. Whether that fits your day depends on your totals, not on the food alone.
Every value on this page comes from USDA FoodData Central, entry 171255 (SR Legacy). Serving figures are converted from the per-100-g data, so rounding can shift a total by a calorie or two.
