Carbohydrates: How many in wine?
If you're on a low-carbohydrate diet, you might want to take wine off your bill of fare for the duration.
Wine contains no fat and no protein, but just about all of its not-insignificant calorie content is in the form of carbohydrates and alcohol, which is metabolized much like a carbohydrate.
Wines vary substantially depending on their alcoholic content and whether they have residual sugar, but a 5-ounce glass of dry white table wine may have 1.0 to 1.25 grams of carbohydrates, while a similar portion of red may go up to 2.5 grams, and sweet wines with their high sugar content will have substantially more, up to the range of 10 grams in a 3-ounce serving of a strong dessert wine like Port.
Bear in mind that low-carbohydrate diets may reduce calories, but they do this by adding a frightening level of calories from fat to your daily intake. I suggest a good moderate lifestyle of sensible eating (including wine!) and exercise, and consult your physician for advice if you feel a need to diet.
