These things are really high in monosodium glutamate (chemical number E621). to find out more google “vaporeon e621” or for more products in general that have sea salt flavoring search “sea salt e621”
you’re right, it’s about as bad for you as salt - but in high consumption MSG, since it contains sodium, can contribute to high blood pressure and hypertension. Google “E621 hyper” for more about that
