I started yesterday with an explanation of complete vs. incomplete protein, and together with a discussion I had with my oldest about nutrition and poverty in the US, reminded me that people in the US actually know very little about nutrition. When I was a kid, they used the 4 food groups and/or a pie chart; more recently they've used a food pyramid, and generally the schools seem to think that's enough information. I remember even as a kid being a bit offended when my teacher told me that a glass of milk could either count as a dairy or a protein food for the day, but not both. That implied that if the body used the calcium in milk, it couldn't use the protein and vice versa, which is absurd.
Let me start by reminding you that I'm not a trained nutritionist, just a self-educated one. A better simplified explanation is that foods provide three main things: protein, carbohydrates, and fats. They tend to be classified by what they provide the most of. Lean meat is mostly a protein, but it usually has some fat. The same with dairy. Whole wheat bread supplies a lot of carbohydrates, but it does have some protein and fat. Some fruits and vegetables supply almost entirely carbohydrates, but most of them are very high in vitamins and minerals that you don't get from the high-protein or high-fat foods.
The estimates of how much protein you need in a day varies, but despite what writers say, it's the food people are mostly likely to skimp on, particularly women. I like to aim for 60 grams in a day, which isn't as hard as you might think, but I focus particularly on protein at breakfast. My favorite nutrition writer (one who wasn't afraid to REALLY explain nutrition in detail) suggested that studies supported 22 grams of protein at breakfast as an ideal, along with a small amount of carbohydrate and fat, preferably including some fruit.
Why? This level of protein, when supported by the other foods, after "fasting" all night, raises your blood sugar to a good level (lots of energy) and keeps it high through lunch. Less protein, especially if replaced with sweetened foods, tends to give you a high level for a short time, then drops below what it was before you ate, making you very tired. If that happens, even a high protein lunch won't get that energy level back. But if you had that good breakfast, then a light lunch with at least a little of each, you should keep that energy level all day. A high fat breakfast, on the other hand, will raise your energy some and sustain it, but not nearly as much as the high protein breakfast.
Think of the carbohydrates like twigs for a fire. Fat turns the twigs into longer-burning logs, and protein is like a draft control, supplying just enough air to burn well without so much that it burns out too fast. Not a very good analogy, but you get the idea...

Protein for the frugal
Ami asked for an explanation of complete proteins, so here's the "quickie" answer; keep in mind this really over-simplifies it (which sounds funny since my post runs on so long), but it's enough information for practical use.
To "build" protein, there are a number of amino acids necessary (called the essential amino acids by some writers). Some your body can produce from other nutrients, some it can't, but if it doesn't have all of them, it can't produce the protein that your body needs. And it has to get all of the ones it can't produce at about the same time, within about an hour I believe.
Meat, eggs, milk, soy and most nuts are complete proteins, that is, their protein includes all of the essential amino acids your body can't produce. If a meal includes a serving of one of these, you can probably use all the protein in the meal. There are other foods whose proteins include some but not all of these essential amino acids. These include grains---corn, wheat, rice, barley, millet, and oats--- and legumes---peanuts, beans, peas, and lentils. These are incomplete proteins. However, the protein in the grains mostly lack the amino acids that the legumes have and vice versa, and they can "complete" each other.
That means if you eat a slice of whole wheat bread (a grain) with peanut butter (a legume), you've given your body all the amino acids at one time. Beans and brown rice or split pea soup with whole wheat bread or corn tortilla with black beans are other examples of combinations. And if you have an incomplete protein with a complete protein, you're fine too. I can't recall right now where sunflower and pumpkin seeds fall, complete or incomplete, and there are a few others.
This probably sounds complicated. But it's really a lot simpler. If you have food from at least two protein groups (meat, dairy, nuts, seeds, grains, and legumes) at a meal, you should have a complete protein. Drink a glass of milk or soy milk with every meal, and you won't need to think much about this.
Just a note: there are a very few research studies that suggest your body might store the incomplete proteins for later combination, but I believe a lot of other research contradicts that. Probably safer to go with the more conservative one hour figure (and I aim to get them at the same time when possible).

Simple snacks
These are the simplest of healthy snacks, those that even complete non-cooks should be able to manage.
Popcorn is a favorite, simple and low-cal, and very cheap...if you avoid the microwave type. If you get a hot air popcorn maker (which seem to be making a bit of a comeback), you can buy popcorn in large bags for less than a box of the gourmet microwave popcorns. And you can completely control how much butter and salt you use. I say butter intentionally because we've found that margarine tends to make the popcorn turn soggy while butter does not. And if you want fat free, keep in mind that all microwave popcorn adds some fat, while none is required for hot air popping.
Crisp cold raw vegetables. Carrots, cucumbers, celery, cauliflower, mushrooms, brocolli, zucchini, radishes, onions, green peppers, and ripe (red, orange, or yellow) peppers all are quite good served raw. Cherry tomato or low-juice tomato slices are also good, but have more potential to be messy. Serve with a simple dip---I like to mix 2 parts plain yogurt and 1 part olive-oil based mayo with a bit of seasoning (things like onions, chives, parsley, dill, salt, pepper). Or use salsa. Carrots and celery are quite good with a little peanut butter. Pick vegetables that are in season and don't overdo the dip, and this is not only nutritious but cheap and filling.
Fresh fruit. Grapes, berries, sliced apple, pear, pineapple, and bananas can be eaten with a sweet dip...I like plain yogurt with some honey stirred in. Again, pick things in season and go light on the dip for nutritious, cheap, and filling.
Berries and milk. This is one of my favorite desserts, something I only get to enjoy for a few months of the year. Wash the berries. Cap them if they're strawberries, and slice large strawberries into quarters. Put the berries in a bowl, pour on enough milk to cover. Crush and add some unsalted nuts and toss on a few chocolate chips. Sprinkle a little sugar on top if the berries aren't very sweet. A cup of berries is about 45 calories, half a cup of skim milk is about 45, a 1/4 cup of nuts is about 50 calories, and add a few chocolate chips and some sugar, and you have a great dessert for between 175 and 200 calories. You can mix several types of berries and nuts or have just one kind of berry and nut each. I leave off the sweeteners sometimes when berries are really cheap and have a bowl for breakfast with a slice of peanut butter toast.
Peanuts, sunflower seeds, and pumpkin seeds. These are generally pretty cheap and fairly nutritious. Peanuts are not a complete protein, I'm not sure about the other two, and if you're watching sodium, you probably should consider avoiding the salted varieties.
Dried fruits. These can be a bit expensive, other than raisins, and sometimes dried cranberries, but a great energy source if you like them.

Groceries for the week of July 16th
Not a bad week, though we did a bit more stocking up, $70.30, but we got some really good deals.
We spent $3.58 on meat, $18.96 on dairy, $16.24 for produce, breads and grains were $10.87, and $20.65 on miscellaneous soups, nuts, and such. My best deal were cans of diced tomatoes with chili peppers for $.15 a can, and I got quarts of strawberries for $1.38 each, as well as some other good ones. I don't think I got a bad deal this week, really.
Coffee's so high that I bought a box of really cheap tea bags as an alternative to try out. We've always had green tea and herb teas around, but not as our everyday drink.
Oh, and the tomato/chili cans paired well with the corn tortillas we bought last week. I warmed up beef broth, a can of the tomatoes and chilies, added about a cup of frozen onions, and some seasonings (salt, pepper, garlic powder, cayenne pepper), brought it to a boil, and added some strips of corn tortillas. It was pretty good served with plain yogurt (as a substitute for sour cream) and a little salsa. It was a bit spicier than I like. Next time, I think I may try making it in chicken broth with a little chicken added and possibly some beans if I have some already cooked, or something that will soak up some of the spice. It could be made with corn, but I'm not a big fan of corn myself. Most of the recipes I've seen either use tortilla CHIPS or fry the tortillas, turning them into chips. I treated them like noodles and it worked pretty well. It was relatively low calorie; even with the tortillas and yogurt it was probably less than 200 calories per person. And cheap: I think the whole pot of soup was less than $.60, but that's because I combined several sales items.

Thoughts on simplicity
Has anyone else noticed that very few of the free recipes available online are simple ones? And the supposedly thrifty ones often aren't (at least not for ordinary people)? I think some of them would add 3 or 4 extra ingredients to instructions for making a grilled cheese.
Don't get me wrong, there's nothing at all wrong with options or variations on a recipe. But honestly, does tortilla soup really require 8 or 10 different spices, not to mention several other ingredients that I've never seen in tortilla soup? This may make a better version (or may not, more complex isn't always better), but it's certainly not necessary. I went to one Web site that's changed hands since I last looked, and the nicely practical, basic thrifty recipes have mostly been replaced with complicated or expensive recipes. The bulk cooking recipe Web sites used to be great too, but most of the recipes now seem to call for pricey ingredients.
I think there are several reasons for this. One is kind of like the change Mother Earth News underwent from the really genuine back to basics stuff when it began (fruit-loopy as some of it was) to the trendy stuff that only appeals to the upper middle class who have a lot more money than the poor; profit tends to push things to target them. Second is also an economic one---recipes are a great way to sell more of some item, and I suspect a lot of things online are directly or indirectly financed by the vendors. Third is also an economic one---people want to produce original versions of recipes and the "best" version so people will pay for their cookbook or classes or something. But last, I suspect a lot fewer of the working class and poor spend much time online, either from lack of computer and internet or from lack of time.
Search engines are also set up to push results of companies that pay for the favoritism up in your results. An example was when I searched for "basic bread recipe yeast". In the first 5 or 6 results there were several from prominent recipe sites that were anything but basic. None of those results was for a non-knead dough either, and while a batter bread recipe isn't great for sandwiches, it's perfectly delicious, and easier to make. Much less intimidating for someone experimenting with making bread for the first time.

Groceries for the week of 07/10/2011
This past weekend, we did a bit of stocking up at one of our secondary stores, with a total of $83.34.
We spent $9.51 on dairy, $37.08 on meat and eggs, $17.11 on produce, $9.18 for grains and bread, $2 for coffee, and $8.46 for odds and ends. That's a lot of money for meat, but we got over 20 pounds of (boneless) meat, and $10 of that went to stocking up on my fat free hot dogs that were on sale.
We've needed a trip to this store to restock on a couple of items, but we'd been watching for a weekend with unusually good sales, which this was. Our best meat purchase was ground chicken for $.99 a pound. A lot of produce was at a good price. We didn't exactly need the coffee since we'd bought some last week, but the small canister was about the equivalent of $6 for the large, so more than worth it. Unfortunately, there was a one-item limit. Our best buy was a very large package of corn tortillas for $.99 (I don't remember the exact number, but I think it was 90). That's a lot to use up, even for us, but I'm planning to try tortilla soup later this week, and we have baked enchillada at least once a week, and migas for breakfast.

Groceries-week of 07/02/2011
I've been offline for a couple of weeks due to computer and car problems and exams in my class. Hopefully I can get back to posting regularly.
Just to keep the weekly record of grocery buying complete, I'm going to jump back to the weekend before last. We spent $48.29, so another payoff week. We spent $3.19 for dairy, $14.04 for meat, $15.85 for produce, $2.19 for bread, $9.44 for coffee, and $3.58 for brownie mixes.
The total would have been even lower except this included food for the 4th of July plus brownie mixes that we made up to take to someone as a thank you for help with the car. The worst deal was the coffee. The price has gone up in the last few months and seems to be staying high. I could have gone a few more weeks, but I hate to chance running short too. Next time I see a good sale, though, I'm buying 3 or 4 cans even if I have to store them on top of the cabinets. Some of the produce was a particularly good price.
However, they had apparently made too many rotisserie chickens because they had a lot of them marked down quite a bit. One of our meat purchases was a really large BBQ chicken for $4.79 (at least twice the size of what's usually sold at that price) that provided lunch and supper that day with enough meat frozen to provide at least 8 lunches for me. I consider it a great deal since it saved us the work and time and avoided turning on the oven in this heat.
