A 50-gram serving of sweet potato noodles only has 170 calories per serving, no fat and no protein. Sweet potato noodles, however, are most commonly eaten stir-fried or in soups, and this can increase the calorie content of the dish. To keep the calorie count and fat content low and the dish nutritious, use only the minimal amount of added fat necessary to make the dish, and choose low-fat additions, such as steamed or boiled vegetables and lean cuts of protein.
Low in Sodium
A 50-gram serving of sweet potato noodles only has 20 milligrams of sodium per serving, which is less than 1 percent of the daily recommended upper limit for adults. According to Colorado State University, most Americans consume too much sodium in their diets. The recommended daily upper limit is 2,300 milligrams. But if you are over the age of 51, have a history of heart disease or are African-American, the upper limit drops to 1,500 milligrams.
Low in Dietary Fiber
With no dietary fiber per 50-gram serving, sweet potato noodles will not help you meet your daily fiber recommendation. Most Americans do not consume enough dietary fiber. In addition to providing bulk to the diet and making you feel fuller after a meal, this nutrient also reduces the risk of constipation, helping the body pass solid waste through the digestive tract more easily. To increase the fiber content of your sweet potato dish, include plenty of fresh vegetables. Common additions include shredded carrots, green onions, spinach or bok choy.
All calories from sweet potato noodles are from the carbohydrate content, with 43 grams of carbohydrates per serving. Carbohydrates are your body’s primary source of fuel and are easily converted into glucose, which is used as energy for your body’s functions. They are also needed for your nervous system, kidneys, brain and muscles to function properly, and excess amounts are stored in your liver and muscles to be used later on. Excess amounts are also turned into fat if they are not used by your body, however.
