Number of ingredients doesn't really matter, it only matters what the ingredients are and in many cases more is better. lets look at regular wheat flours to start, given the options of pure white flour(wheat endosperm), enriched white flour(wheat endosperm + added minerals), or wholewheat flour(wheat endosperm + bran and germ) according to the logic of "more is bad" the pure would be the best but it's objectively the most nutritionally deficient.
