The calorie and sodium content of wine varies by type, but wine is typically a low-sodium beverage. That said, the calories in wine can add up quickly after a few drinks, which is one reason why moderate consumption is recommended. Women should limit themselves to one glass of wine per day, while men should cap their intake at two glasses per day.
On average, 5 ounces of red wine contains 125 calories, while the same serving of white wine has 121 calories. Ounce for ounce, that's more than double the calories of non-diet soda. Like soda, however, calories from wine provide little nutrition even though they may widen your waistline.
Winemakers often use a process called sodium ion exchange, which clarifies the beverage and helps minimize sediment. This adds some salt to the wine but not much. Four ounces of domestic red wine typically contains about 12 milligrams of sodium, while domestic whites have about 19 milligrams in the same serving. Imported wines have less, at 6 milligrams for reds and just 2 milligrams for whites. The daily sodium limit for most healthy adults is 2,300 milligrams per day.
