Will eating instant noodles twice a week cause some effects?

Yes- it depends on:: Everything we eat affects our health. Instant noodles are mostly carbs; a high-carb diet raises blood sugar, increases obesity, causes inflammation etc.Most instant noodles are wheat ; thus have gluten, which adversely affects many people (but you could have rice or buckwheat noodles without gluten). Most have msg as a flavor-enhancer which may be toxic- see http://bit.Ly/1cj9f5f best only on occ.
