Having clarified that we are not nutritionally deficient because of the quality of our food, let's take a look at the actual nutritional supply of Germans. Until then, we need to figure out where to get an accurate picture of the Germans' nutritional supply and needs.
After a lot of expensive scientific research in recent years, researchers have learned a lot about the body's need for vitamins and minerals, most of which are much smaller than the actual intake of Germans.
When we learn that in fact, the human body does not always need micronutrients in the process of metabolism, and it is easy to understand that the demand for micronutrients is small. In other words, a vitamin molecule must repeatedly perform many physiological tasks before it can be honorably discharged. For example, vitamin B1 is involved in glucose breakdown, but not every sugar molecule is broken down by losing one vitamin B1 molecule. In fact, a vitamin B1 molecule can participate in the decomposition of countless sugar molecules, so it is a big mistake to call sugar a "robber who robbed vitamin B1".
Most micronutrients need to bind to functional proteins in order to perform their physiological functions, so these "cellular machine overhauls" must first isolate the corresponding vitamins or minerals. Our body is very calculating at this point, and in the case of insufficient supply of micronutrients, it will be very efficient in reusing micronutrients and slowing down micronutrient excretion.
The reason why our bodily mechanisms are so self-evident. It is conceivable that our ancestors often fell into a situation where there was no food to eat for days or weeks in the process of evolution, and if the body did not evolve the most efficient micronutrient conservation mechanism, how could humans survive to this day! This is why, from a medical point of view, micronutrient deficiencies today can only occur if the diet is too simple or if you suffer from certain diseases.
Another point we need to make clear here is that the upper limit given by professional associations on the body's micronutrient requirements can only maintain the metabolic function of most people at an ideal level to prevent micronutrient deficiencies. If you have been diagnosed by a doctor as deficient in a certain micronutrient, you must replenish your body's micronutrient reserves with medications. In this case, the official recommendation value is too low.
Another problem is that for the detection of many micronutrients, either there are not enough sensitive instruments, or the detection methods are very complex and very expensive. As a result, people can sometimes only determine if they are deficient in a certain nutrient by recording their diet. But this method is not reliable.
One can compare one's own recorded diet to the recommended values of professional associations. For safety reasons, professional associations have a large surplus of recommended values. This is done in consideration of factors such as the difficulty of absorbing vitamins and minerals in certain foods, the loss of nutrients during the cooking process of food, and fluctuations in the amount of nutrients in food.
Even if the intake of micronutrients is less than recommended, it does not mean that the body will be nutritionally deficient. A lack of medical significance can only be said to have occurred if accompanied by changes in biochemical indicators or the appearance of clear symptoms. A professional dietary record sheet can provide valuable information about what went wrong. We can make a dietary schedule and decide how to adjust the diet in a targeted manner.
However, the opinions of some "godfathers of supplements" are completely different. They complain that the claims of professional associations are completely misleading to the public that people can only use nutritional supplements to achieve their desired health and exercise effectiveness. Even in some very harsh and extreme cases, there are people in the medical community who claim that certain serious diseases can be cured by specialized nutritional supplements (of course, they market themselves). This is entirely irresponsible to the patient, an unethical act that puts the patient at risk to their health (unfortunately, this has been confirmed in some cases).
In addition, we also need to know that the human body demand for each micronutrient given by professional nutrition institutions around the world is similar in order of magnitude. The slight differences between the reference values given by the professional nutrition agencies in different countries are not because the demand for this micronutrient is different for the residents of different countries, but because of the surplus value set aside by different official institutions.
Another thing is that micronutrients, as the name suggests, can actually do well in very small doses. Its pharmacological effect is achieved through a considerable dose, and the dose only through dietary intake is not enough. We must learn to distinguish between the words "need" and "lack". Micronutrient "deficiency" is not about nutrition, but about the efficacy of the drug.
In Germany (and of course in other parts of the world), a wide variety of studies are assessing the vitamin and mineral supply of residents as precisely as possible. In addition, there are various studies specifically targeting groups such as the elderly, pregnant women, children and infants. One of the most important research projects at present is the "National Dietary Consumption Study 2". The results of these studies are summarized in dietary reports published every 4 years. The 2008 Diet Report has just been published from the data released and we can see whether and in what ways Germans may have a problem with a shortage of micronutrients.
