@OogieBoogie These overdoses are deliberate, to make such foods addictive.
You used to hear complaints that the "own-brand" or own-contract foods available in some supermarkets were somehow of "lower-quality" to the long-established "big name" brands, simply for a slightly different taste. The truth is that the own-brands have considerably less sugar and salt than the Big-Name makers add to enhance their products' sweetness and flavour artificially, to boost sales.
@OogieBoogie Indeed! They do at least have to list the ingredients and those values, but in the end it it is still for us to judge for ourselves what we buy and how often.
I have a sweet tooth so do like desserts probably similar to that Oreo but I do try to limit them, and to eat a vaguely-sensible diet.
