Mostly all of the instant noodles are made up of refined wheat floor i.e. Maida which is harmful for our body. Our stomach is incapable of digesting it properly thus it gets deposited under our skin making us fat. As we keep on eating it more this layer gets thicked leading to obesity and high blood pressures as the veins carrying blood gets blocked due to these deposits. Hence try to avoid eating instant noodles for a healthier body.
You can opt for whole wheat noodles that can be made at home in a noodle maker as a better alternative.
Stay healthy, Stay happy :)
