As I continue through this text book I am amazed to find out what my Grandmother knew about foods that few people know today. I know that little or none of this is taught below a collegiate level and maybe then only in graduate nutrition and science programs.
Importance of milk. The general wisdom of the day was that milk in the diet could save a housewife work and worry in planning well=balanced meals. So important was it at that time that scientists said a quart of milk should be used daily until a person was grown but after that a pint. It was not necessary to drink an entire quart but it could be added to the diet in other ways.
The importance of milk was due to its ability to support growth, repair body tissue, to protect the body against "deficiency diseases" to supply fuel and to keep us young and vigorous. There is mention here of the various animals world wide that were/are used for milk production.
Composition of milk. Because most of us do not have a cow in our back yard anymore, and we buy it at the store we can know that our milk comes from mixed herds. What people in this generation generally knew was that milk varied in composition according to the cow, the season and what the cow was eating at that time.
The average composition then, I am going to look when I go to the store and see if I can verify this today: Water 87% Protein 3.3% fat 4% carbohydrates 5% minerals .7% containing larger amounts of vitamin A, moderate amounts of vitamin B ( am thinking they didn't know about the what, 7-8 B vitamins now known?) and small but useful amounts of vitamin C
The next section is Milk Regulations. Milk regulations varied somewhat but usually included these three things.
1 The composition is usually standardized by the regulation of total solids--3.25% milk fat and 8.5% of other solids. Thus 88.25% of your milk could be water. This was to prohibit the skimming of "whole milk" or the watering it down.
2 The bacteriological count should be low in clean milk. Some city health departments then required that milk be graded into A, B and C grades according to the bacterial count. Certified milk was even superior to grade A and not readily available.
3. The most affective form of controlling the quality of the milk supply in days of having a choice in your supply seemed to be scoring all dairies and publishing those scores. People bought milk from dairies that scored highly. People wanted clean milk, can you imagine?
Some of the things they looked for in scoring were healthy cows, workers that were healthy and clean and the utensils being sterilized in steam or boiling water.
Bacteria as we know multiply rapidly in warm milk. To keep the growth down milk should be cooled to 50 degrees or below. in an experiment sited milk kept at 50 degrees for 24 hours increased in bacteria five times but milk kept at 70 degrees (room temp) in the same time increased 750%
Pasteurization of milk. This process consists of heating the milk to 145 degrees for 30 minutes. This does not boil the milk but does destroy the disease causing bacteria. I knew that we pasteurized milk but honestly never knew what bacteria for, I guess I assumed just spoiling. The disease bacteria that the authors of this book say we are killing is typhoid, diphtheria and tuberculosis. This process does not prevent spoiling.
Food value of milk. Protein n milk (3.3%) the term protein is a class of substances that vary somewhat in their properties. Some of them are albumin (in eggs) Legumin ( in beans) myosin (in meat) gliadin and glutenin ( in wheat) lactalbumin and casein ( in milk) Proteins are not all equal in what they do for body building and repairing of tissue. Some which when used as the only protein element in the diet will support both growth and repair are called complete proteins. Others need help along the way to be a complete protein.
Milk proteins are complete proteins which is why nature provided that substance as the sole food for the very young during the period of most rapid growth.
Fat in milk ( 4 %) The most significant fact of the food value of the fat in milk is that it is high in vitamin A which is a fat soluble vitamin. Vitamin A will also be found in cream, butter and cheese. The fat in milk is for most people very easily digested due to its finely divided form and its low melting point
Carbohydrate (5%) Lactose or milk sugar is the carbohydrate in milk. When the lactose ferments it changes to lactic acid. It was thought at this time that lactic acid was beneficial in checking the growth of certain putrefactive bacteria that cause intestinal disorders. We do know that we need good bacteria in our bowels today to keep us healthy, can you say lactobacillus acidophilus?
Minerals (.7%) Milk is rich in most of the minerals needed by the body Calcium I the obvious one to us but it also contains phosphorus and iron. Iron is not abundant in mild but it is a very superior quality. This book also mentions that while babies are born with a large supply of iron, before the end fo the first year it is necessary to supplement that from not only milk but such foods as egg yolk and green leaf vegetables.
Vitamins: Vitamin A in milk helps prevent diseases of the eyes, lungs and throat. B associated with growth and good nutrition. Low amounts of vitamin C however. For this reason orange juice or tomato juice was introduced early into infants diets. It is an especially good source of calcium. It is a good source of protein, fuel, phosphorus, and vitamin B. Milk needs supplementing for iron and vitamin C it is not a sole food source for adults because it does not contain enough of some of these things plus it has no cellulose, for the intestines.
Fuel for energy value. In this book the amount of calories listed for a quart of whole milk is 675. Today what I am finding is in the upper 500s I believe the change has been in the way we feed our milk cows and the way we allow for exercise in our animals as well as probably differences in types of cows we generally use. At that time, approximately the same amount of calories was in a pound of steak Again, now steak has more calories because we like cornfed marbleing in our steaks which is ummmmm FAT. Grass fed beef is a whole other conversation.
Milk products: Skim milk and buttermilk have all the food value of milk except because fat is taken out, there is also less Vitamin A. Whey has some food value, but the protein and fat have been removed leaving the water, carbohydrates, minerals and water soluble vitamins B and C.
Condensed milk is in two forms, sweetened and unsweetened. The sweeteed is condensed one third and the unsweetened is condensed 1/2. I find that interesting because the sweetened kind is so much thicker than the unsweetened. I mean come on, you can eat IT with a spoon.. you would have to drink the evaporated milk. Condensing the milk does not change any of the food value except the vitamin C because either form has to be heated which destroys vitamin C.
Dried milk is made from either skim milk or whole milk and in the past has been considered a very important food. It contains all th food value of milk again with probably the exception of vitamin C is useful in cooking and is useful in either places where there isn't a safe supply of fresh milk continually or in homes where milk is used sparingly.
Cream contains from 20 to 40 percent fat. It also has the rest of the parts of milk but in lesser amounts over all.
Use of Milk for Breakfast: One glass of your daily amount of milk should be taken at breakfast however you don't have to just drink it. This amount can be used over fruit, or cereal, over toast, in breads, as a sauce for eggs or always the good ole cocoa or chocolate milk.
Milk cookery: The most obvious effect of cooking milk is the formation of a skim on the top, this is largely fat and protein (lact-albuin) Try not to let this form.
Cooking does change the taste of milk. The sugar and fat in milk can easily burn which will give milk a scorched taste so when cooking milk for sauces or puddings and such use a double boiler instead of direct heat. Boiling it makes milk more digestible by making softer the curd that is produced in our digestive system If milk is boiled though it should be done quickly boiled one minute and cooled quickly. This will prevent the skim from happening and thus the burning.
Rules for care of milk in the home: Keep it clean, covered and cool! As soon as it was delivered (yes home delivery) it should go in a cold fridge, in the part of your fridge that would keep it below 50 degrees. Do you know if your fridge has different temps in different places? Experiment here we come. Interestingly it says buy milk in bottles. One was also to wash the mount of the milk bottle before pouring the milk each time and never mix old and new milk.
Here is another quote from the book I found amazing. "The refrigerator should be kept scrupulously clean DAILY and should have a through cleaning WEEKLY. Milk and butter absorb odors easily so you should not put them in a place in your refrigerator near foods with a strong odor.
The last section is titled Cocoa and Chocolate
Food value The main food value of cocoa and chocolate as a breakfast beverage is due to the milk but they also have food value themselves In this respect they do differ from tea and coffee. Both contain theobromine a stimulant similar to the stimulant in tea and coffee.
Percent composition of cocoa and chocolate. Fat is the chief food constituent. Plain chocolate contains about 50% fat. Cocoa contains about 22 percent fat. One square of bitter chocolate yields of one hundred and seventy calories and one tablespoon of grated chocolate yields thirty calories.
One tablespoon of cocoa pulverized has @ 30 calories. Both cocoa and chocolate are rich but chocolate is richer even though both are made from cocoa beans some of the fat is removed in the production of cocoa. This makes cocoa the better choice for breakfast and for children and people with weak digestion.
My home practice this week is going to deviate from the book. Because several members of my family and I have lactose intolerance issues and have lived with less milk in our diets, I am going to explore the differences in nutrition from using milk to coconut milk to almond milk, our personal favorites. I am substituting both in several recipes already but generally those are things baked as both are sweeter than regular whole milk. If anyone has any knowledge on the subject of the vitamin and mineral content of each, I would love for you to share it.
