Fontana White Chocolate Mocha Syrup is a brand of coffee flavoring produced for Starbucks. Starbucks sells the syrup to consumers and also uses it to enhance the flavor of various coffees available in their stores. Although coffee itself is low in calories, Fontana White Chocolate Mocha Syrup is not, as it is high in sugar.

The first ingredient listed on the syrup's label is sugar, followed by condensed nonfat milk, sweetened condensed nonfat milk and coconut oil. It also contains more added sugar in the form of high fructose corn syrup and cocoa butter for a boost of flavor. The ingredient list includes natural flavor, salt, the preservative potassium sorbate, and monoglycerides, which are used as emulsifiers to ensure the ingredients stay mixed together. Fontana White Chocolate Mocha Syrup has 120 calories in a 1-ounce serving. That means you'll get almost as many calories as a can of sweetened cola.

Coffee is naturally fat-free, but when you flavor it with Fontana White Chocolate Mocha Syrup you'll add some fat. Each 1-ounce serving contains 2 grams of total fat. While that amount qualifies as low fat, the entire 2 grams consist of saturated fat. This type of fat increases your levels of LDL, or bad, cholesterol, which can raise your risk for heart attack and stroke. The American Heart Association recommends limiting saturated fats to less than 7 percent of your total daily calories.

Most of the syrup's calories come from carbohydrates: You'll get 24 grams of carbohydrates in a 1-ounce serving. The carbs consist entirely of sugar added during processing. This type of added sugar provides calories without any nutritional benefits. Women should limit added sugar to 6 teaspoons or less daily, while men should not consume more than 9 teaspoons daily, according to the American Heart Association.

Thanks to the condensed nonfat milk in Fontana White Chocolate Mocha Syrup, you'll get 2 grams of protein in a 1-ounce serving. Institute of Medicine guidelines recommend that 10 to 35 percent of your daily calories should come from protein. For women this translates into about 46 grams daily, while men should aim for 56 grams of protein each day. Based on these values, the protein in 1-ounce of syrup provides about 4 percent of your recommended dietary allowance for protein.

This syrup is not a good source of most vitamins and minerals, but the condensed milk provides some calcium. As a result, each 1-ounce serving supplies 6 percent of your daily value for calcium, based on a 2,000 calorie-a-day diet. In addition to its well-known role building bones and teeth, calcium is also an essential electrolyte. In this role, it carries an electrical charge that helps keep your muscles and nerves working.
