While I like the Mountain House Beef Stroganoff Pro Pack best for flavor and total calories (500), it does have a drawback, namely it’s high in saturated fats. But it has 36% fat calories, and only 12 gm of sugar. It comes in at 125 cal/ounce, pretty good.
Perhaps the most nutritious of all is the MH Beef Stew Pro Pack. It has 119 cal/ounce, low % of saturated fats, low sugars, and a good calorie balance (25% fat, 45% CHO, and 30% protein). The bad part is that it contains 2390 mg of NaCl (ouch!).
The MH Pro Pack that most closely matches the FDA recommended calorie ratio is their Chili Mac (27% fat, 53% CHO, and 20% protein). It yields 118 cal/ounce with low sugars, and the % of saturated fat is about average for the MH line.
If you want to bump up the protein there are a couple of powdered nutrition powders that I like (but they aren’t cheap). The more palatable brand is NutriBiotic ProZone ( I get it at Vitamin Cottage). The caloric balance is interesting at 29% F, 41% C, and 30% P. The drawback is that it’s a bit high in saturated fat and sugars. I re-package it into 3.0 ounce portions, which I vacuum-seal. Each one yields 372 calories, or 124 cal/ounce. It makes a pretty decent breakfast shake, a higher protein alternative to Ensure.
Another high protein (and high fat, with VERY low carbs) shake mix I’ve gotten into recently is the Vega One shake mix from Whole Foods or Vitamin Cottage. Its caloric breakdown is 29% F, 20% C, and a whopping 51% complete plant protein. A 3-ounce portion of this yields 351 calories, or 117 cal/ounce.
As I mentioned, these two specialty powdered mixes aren’t cheap. The 3 ounce portions of NutriBiotic ProZone are about $3 each, whereas the Vega shake mix is about $3.50 for just a 1.75 oz. portion. Also, since the Vega is unsweetened (so fairly “plant tasting”), I add some stevia to it, and maybe some vanilla extract to make it more palatable.
If I’m not terribly worried about my caloric balance, say while on a 2-3 night trip, I just take 3-oz portions of powdered Ensure for a quick and easy breakfast. 127 cal/ounce, and it has probably the best overall caloric balance (though it’s high with sugars at 20 gm/serving). Though Ensure is rather expensive at ~$2.50/serving at Walgreen’s, they offer a 20% discount for seniors on the first Tuesday of each month. That brings the price down to $2.00 per serving, which is about the best I can do for a good nutritional shake mix.
The other thing a lot of us do to control the nutrition of our meals is to dehydrate our ingredients, combine them, add our special spices, etc. and then vacuum seal individual meals. The storage life in my cool, dark Colorado basement is easily 3-5 years. But this doesn’t seem like something you will want to get into.
