Instant ramen noodles are a popular, affordable convenience food, but in their basic form they are not very nutrient-dense. Most ramen noodles are made from refined flour, which provides calories but little fiber, protein, or essential nutrients. As a result, ramen alone may not keep you full for long or support balanced nutrition. Many brands also pre-fry the noodles to achieve their texture, increasing saturated fat content, which should be consumed in moderation.
