Q. If I enter french vanilla coffee into the database, "Coffee, French vanilla nut, inst"; when I put in 2 cups, it calculates it as 1400 calories, is this accurate?
A. The data for that food is accurate; it is an instant coffee, so the food itself is dry. The default serving for this item, which is used to make 1 cup of liquid coffee, is 1.33 Tablespoons (14g). If your subject had 2 cups of prepared instant coffee, the serving size would be 2.67 Tablespoons, or 28g.
