 The very first food for any person (not without reason the genus Homo belongs to mammals) was milk. It is said that only one product in the world can replace it when feeding infants - a suspension from raw liver (apparently, reindeer), and then after some processing.
Under ordinary "civilized" conditions, there is no need for such a replacement; naturally, no one is going to experiment on children, so it is difficult to conclusively confirm this. However, many years ago, even before the war, supposedly somewhere such a need arose and the experience was successful.
What is this wonderful product that is so irreplaceable - milk? Professor KS Petrovsky writes: "Milk and dairy products differ from all other food products in that they contain all the nutritional and biologically active substances necessary for the body in a balanced state." What does “balanced” mean will become clear from our further considerations, but we can already say that milk alone can satisfy all food needs.
If so, why not eat only milk? Or derivatives of it? Why grow bread, potatoes, sugar beet, breed pigs and chickens, catch fish? Can you imagine how much easier it would be for humanity to live if it switched to a purely milk diet? By the way, it is the production of milk and dairy products that is easiest to intensify and mechanize, it is here that there are the smallest losses of finished products - insects and rodents do not steal milk, do not spoil it, unless, of course, do not treat it wastefully, bacteria (and after all, a third of the food produced by man goes to these "tax collectors"). Consequently, the transition to a similar power supply unification promises more. huge economic benefit, which is also important.
But ... It cannot be that there is no disguised "but" here, otherwise how to explain that such recommendations had not been given by anyone before and were not spontaneously implemented by the population. However, before insisting on the urgent implementation of your proposal, it is advisable to consider in more detail the nutritional value of the substances contained in milk and estimate how much it should be drunk per day to fully meet the needs of an adult. There is no need to talk about children, everything is clear with them - milk and only milk, at least for the first five to six months of life.
For consideration, let's take, of course, cow's milk. First, for the absolute majority of the world's population, it is the most familiar, although they also drink the milk of donkeys and the milk of camels, and the chemical composition of the milk of giraffes and elephants is also known; mice, whales, etc. But what practical sense is that the fat content of milk, for example, of mice and whales, is almost the same and higher than that of cream sold in the store - 22.5%. Second, cow's milk is the most readily available.
The standard milk defined by GOST contains the following substances: water - 87.8%, fat - 2.5, proteins (casein, albumin, globulin, etc.) - 3.2, milk sugar - 4.7, organic and inorganic salts acids (minerals) - 0.65%, and in addition, at least seven vitamins and a small amount of other compounds.
Now let's estimate how much milk an average adult weighing 70 kilograms needs to drink to cover energy needs.
Any work done in the body and the body requires fuel consumption. It was only my daughter who, when she was little, believed that water was needed to heat a city apartment, but not fire (since water circulates in the central heating batteries, but the fire is not visible). Now she, with a laugh, recalls her childhood performances.So, fuel. Fuel for internal organs to work - heart, liver, stomach, lungs, kidneys ... Let us sleep or lie motionless, looking at the ceiling - the body works, energy is spent.
Roughly it is believed that under average conditions (ambient temperature, humidity, etc.), approximately 1 kilocalorie of energy per 1 kilogram of body weight per hour is produced and consumed at complete rest. Therefore, for the whole person - 70 kilocalories per hour.
Energy consumption during mental, and even more so physical activity increases sharply. Thus, a quiet reading of a not very emotional novel "costs" the body exactly 100 kilocalories, a quiet conversation already takes 106, and laboratory work while sitting - up to 180 kilocalories per hour. 4-7 times more energy is spent during heavy physical exertion. Somewhere in the middle between these figures (i.e., mental and hard physical work), there are indicators characterizing energy consumption during household activities - washing, cleaning floors, cooking, etc.
If we calculate all this, and such calculations have been made, and we will use them, reproducing from a textbook on food hygiene, it turns out that the minimum energy expenditure is determined at 2200-2600 (the first figure is for women, the second for men), the maximum is 3600-4000 kilocalories per day. The calorie content of cow's milk is 625 kilocalories per liter. Thus, to cover the minimum requirements, the average woman should drink about 3.5 liters of milk (2200: 625) per day, and a man 600 milliliters more. To meet the maximum costs, a woman will need 5.7 liters and a man 6.7 liters. Well, the dose is not too large, although, if you mean the liquid as such, it is somewhat excessive. But at the same time, it cannot be said that such mono-nutrition will not have a detrimental effect on the body.
