Where do the calories in wine come from?

Alcohol is the main source of calories. Each gram of alcohol contains 7 calories. Therefore, a glass of 15% alcohol Zinfandel (Zinfandel) has more calories than a glass of 11% Albarino (Albarino). In addition, carbohydrates are also a source of calories. Each gram of carbohydrate contains 4 calories. A glass of dry wine contains about 4 grams of carbohydrates, while a glass of sweet wine contains 20 grams of carbohydrates.

The above data is based on a 2013 study, that is, the calorie content of a 5-ounce glass of wine. When people drink heavily, the calories they consume are often beyond imagination.

Does the calories of wine have nutritional value?

Drinking wine in moderation, especially red wine, has been regarded as a good habit that is good for your health and may also have a slimming effect. Studies have found that when people drink wine, the polyphenols of red wine can prevent the direct conversion of greasy foods, and at the same time can inhibit glucose from entering fat cells, so the overall calorie intake is relatively small. Generally speaking, people who drink wine in moderation can maintain a healthier lifestyle than the general population, but this does not mean that wine alone can lose fat. In addition, wine itself cannot serve as a meal, so the nutritional value of wine cannot be explained solely from calories.
