"Requirements - The Food and Nutrition Board recommended a sodium intake of less than 2,400 mg/day for adults."

They say that athelete who are exercising more than 2 hrs a day would need more due to excessive sweat losses.

And "hypertensive individuals are recommended to limit their sodium intake to less than 2,400 mg daily..."

"Toxicity - Excessive consumption of sodium on a regular basis is often associated with hypertension and edema. High intakes of sodium can also lead to osteoporosis because sodium can increase urinary calcium losses.

"No upper safety limits for sodium have been established because the body generally excretes excess sodium through the kidneys. But health organizations recommend daily consumption of sodium < 2,400 mg per day (about half of that found in the typical American diet)."

I just picked three random meals from the Mtn House choices and all were over 5,000 mg. If you're a young adult in good health, with no hypertensive issues, you could probably get away with it. But it would be like eating fast food all day, every day.

If you're middle-aged or so, it wouldn't be very good.

If you only ate one MH meal per day (say dinner), and ate more regular stuff for your other meals, it would be better. Say a double portion of quick-cooking oatmeal with milk (reconstituted dry) and two tablespoons of brown sugar would have about 125 mg of sodium.

Balance is probably the key.
