Wat? What spices contain a high level of sodium? Or are you counting 'salt' as a 'traditional Indian spice'?!
That said, I don't understand how you have this much salt in these packs. I'm south indian and cook on a regular basis; specifically I cook these foods quite often and the spices involved generally don't have salt mixed in (unless the spice mix wasn't ground by you originally and so I can see how the salt would be mixed in, but still)
The majority of Indian spices are mostly single element spices - cumin, coriander, fennel, fenugreek, garlic etc.
Even Garam Masala probably the most widely used multi-spice doesn't contain any salt.
Could you elaborate on which "traditional" Indian spices have salt in them?
As an example, you'd need around 5 kilos each of both ginger and chillies to come close to the sodium content of one of these meals!
Personally, I don't have a problem with them having a high sodium content - but I do have a problem with nonsensical claims by the maker.

This is untrue, bastardized Indian dishes tend to overcompensate for not only sodium but also oil. I'm guessing the extra sodium and sugar in your dishes are added to appeal to Americans and keep a longer shelf life...
