Oranges aren't the only way to get the C you need.

A cup of orange juice gives you over 200 percent of the recommended daily intake of vitamin C, but it also contains a whopping 26 grams of carbohydrates. A better option? One small, red bell pepper contains even more vitamin C than orange juice and delivers only 4 grams of carbohydrates. Other good sources of C are green peppers, strawberries, broccoli, and tomato juice.

A note on grapefruit juice: Even though it tastes a lot less sweet than orange juice, it has virtually the same, high carb count. If you're a fan, grab a pointy-tipped spoon and eat half of a grapefruit instead (about 10 grams of carbs).
