Good suggestions William. I don't know how much your rice is up there where you are, but I can buy 20 pound sacks of it for less than $10 here.
Protein powder is a good idea as well, just got to watch it close if it has whey powder in it. I've had to use it before for medical reasons and that's what the nutritionist told me. If you know of a good protein powder that is sugar-free and is drinkable without being made with milk, please let me know.
What is this about whey? I've only encountered information stating it is one of the best protein powders out there.
It is soy protein that is dangerous to consume in large quantities especially for guys.
It is better than rice protein also because it is a complete protein, kindly supply more info on any issues you know of in regard to whey.
If it is lactose intolerance, I am very mildly lactose intolerant... WHEY isolate has most of the lactose removed. also the ALLWHEY brand mix I just got is very low lactose also due to having a bunch of enzymes such as lactase added to it.
If your medical issue is lactose intolerance get whey isolate, or something that has digestive aids added to it such as the Allwhey I had, relatively economical price for 10lbs it ran around $120 so about $12/lb. of 80% protein. Its not cheap but I find it very useful since I lead a mostly vegan/vegetarian lifestyle, although I do eat most anything, I tend to only buy fish/eggs and where it occurs dairy products, but I tend to not buy processed dairy.
There is egg protein
There is a bunch of others also whey tends to be the lowest in price in terms of bang for buck.
If you eat meat there are plenty of alternatives,
the 10lb allwhey allows for 2 months at 60grams per day, which is enough to boost protein intake, since 40 grams from other sources is doable on rice/lentils/beans etc.. for 100gram intake goal. 40grams natural source 60 grams whey nutritional blend which includes taurine, glycerol, digestive enzymes and some amino acids (bcaa's) its a mix whey isolate concentrate mix for fast absorption and slow release. If I was a serious body builder I could double my intake and do $4 a day instead of $2/day but I'm fine at about 1-1.2x body weight intake.
I tend to trust the whey way more than commercial slaughter and processed meats, it just seems like a cleaner source.
I'm also thinking a quick fix if the "mass gainer" products out there as they tend to be high calory, but they are costly.
I've been aiming for some RTL hens, but no one delivers out here... 3 or 4 hens would supply me with enough eggs to keep my protein level mint.
In terms of whey powder a 6 month supply at 60 grams a day runs at about $360 which works out to 30lbs or 6 5lb containers, you might be able to get a better price. It is an easy fix to insure protein.
Fats are easy with olive oil, or hard stuff like lard.. but I prefer oils because I consider them more manageable, for recipes but a mix of the two would probably suit most people. Say perhaps $50-100 worth should cover you for 6 months
For carbs, rice is probably the cheapest, and I suggest a mix of flour and rice for each grown adult 1 8kg bag should last 2 weeks so 2 bags per month or 12 bags for half a year should run less than $150 probably closer to $100
a couple dollars worth of salt should cover you for your salt needs.
and 1 or 2 multivitamins a day so two to four 120 cap centrum type multivitamins this should run maybe $30
a water purifier, perhaps some jugs of water filled should be a "baseline"
so perhaps $600 should be able to get you the baseline of supplies for 6 months.
I also recommend a big bag of sugar. which an 8kg bag should be under $10
most people in an urban setting should be able to get nutritious greens, vitamin c etc.. from nature most plants you see are edible
An added benefit to the protein powder method is that it gets you use to drinking say ateast 1 litres of water a day. Also depending on flavours it can be a morale booster. I buy vanilla usually though, because it is easier to cook with, but there is chocolate, peanut butter, fudge, strawberry you name it flavours.
