As temperatures soar, many people reach for refreshing summer favorites such as naengmyeon (cold noodles), kongguksu (soy milk noodles) and shaved ice desserts. But these seasonal staples often contain far more calories, sugar and sodium than expected. Here are five popular summer foods that may quietly sabotage your diet. Naengmyeon Depending on the type, a serving of naengmyeon contains about 500 to 700 calories. More concerning than the calorie count, however, are its high carbohydrate and sodium levels. Many commercially sold naengmyeon noodles contain relatively little buckwheat and are instead made primarily from starch, making them high in carbohydrates. The chilled broth also often contains sugar or high-fructose corn syrup. Drinking all of the broth can provide more than half of the recommended daily sodium intake. Those trying to lose weight are advised to leave most of the broth behind. Adding a boiled egg or slices of lean meat can boost protein intake, helping slow blood sugar spikes and keep you feeling full longer. Kongguksu A bowl
