As the culinary website Chow explains, peanut sauce is popular in many Asian cultures, and can be used for dipping, as a salad dressing, or as a sauce for noodles. Although some sauces tend to be low in calories, peanut sauce is high in calories.
According to online nutrition resource MyFitnessPal, a two-tablespoon serving of peanut sauce contains 70 calories. This is significantly more calories than many other sauces contain; for example, barbecue sauce contains 35 calories per two tablespoon serving, according to MyFitnessPal.
Peanuts are high in fat, and peanut sauce contains some fat as a result. MyFitnessPal explains that two tablespoons of peanut sauce contains 3 g of fat, with 1 g of saturated fat.
Two tablespoons of peanut sauce contains 7 g of carbohydrates, according to MyFitnessPal. The website notes that this serving contains 1 g of fiber and 5 g of sugar. The National Library of Medicine and National Institutes of Health explain that while carbohydrates are your body's main source of fuel, you should limit sugar intake, as it provides calories but little nutritional value.
Peanut sauce is low in protein, with just 2 g in each two tablespoon serving, according to MyFitnessPal.
