Questions of health and nutrition are out of scope for this site. However, the question "what are alternatives to these instant noodles" is pretty straightforward.
Instant noodles are typically preserved by flash-frying in oil. They arose as a quick-to-prepare and long-lasting alternative to fresh or frozen noodles. Thus, fresh or frozen noodles are a great replacement. Though they need to be refrigerated or frozen, and may require a longer cook time, they are typically made without oil.
In particular, both noodles in your question appear to be instant Korean ramyeon, which is very similar to Japanese ramen. In the United States, Sun Noodle produces fresh Ramen noodles that are commonly available at supermarkets or Asian grocers.
