# A Spiritual Scientific View of Nature and Man

## GA 352 — 23 January 1924, Dornach

### II. Nutrition

I would like to add a few more things to what I told you last Saturday, and I can answer the two questions I was given for today next time. We talked about poisons and their effects on people, and we have just seen from the poisons that if you understand real science, you have to ascend to the supersensible, to the spiritual parts of the human being.

Now, in order to give you a complete picture, I would like to add to what produces such strong toxic effects, so that you can see the full picture, what the more or less healthy body can cope with when it comes to nutrition. I have spoken about nutrition several times, but let us talk about it again and take into account what we presented last time.

When it comes to nutrition, humans mainly consume three to four types of food. The first of these is protein, which you can best recognize by looking at a chicken egg. Protein is produced by plants as well as by animal and human bodies. Not only do human and animal bodies need the forces they have within themselves to produce protein, because every living body produces protein, but they also need the protein that is independently produced by plants. The human body also absorbs animal protein. In relation to this protein, science in particular has basically been embarrassed in the very latest times; because it was still taught everywhere twenty years ago that a person must absorb at least 120 grams of protein per day in order to stay healthy. And so the whole diet was organized in such a way that people were prescribed which foods they should eat in order to get the necessary amount of protein into their bodies. It was believed that 120 grams were necessary.

Today, science has completely abandoned this view. It now knows that if a person eats that much protein, not only does it not help their health, but it directly contributes to their illness, because most of the protein in the human intestinal tract decays. So that the human organism, by consuming 120 grams of protein a day, constantly has something like rotting eggs in its intestines, which terribly contaminate the intestinal contents and sweat out the poisons, which then pass into the organism, into the not only easily produce in the body what later leads to so-called hardening of the arteries – most hardening of the arteries comes from eating too much protein – but also what makes people extremely susceptible to all kinds of infectious diseases. The less protein a person consumes, the less he is exposed to the risk of contracting diseases – provided, of course, he has the necessary resistance. People who consume a lot of protein contract infectious diseases such as diphtheria, measles, and smallpox more easily than people who do not consume as much protein.

It is indeed very peculiar that today science teaches that not 120 grams of protein are necessary, but only 20 to 50 grams. That is the amount, they say, that a person actually needs daily. In just two decades, science has so quickly changed its views. So you can see how little you can actually rely on when something is supposedly scientifically established. If you happen to need to inform yourself on this subject and you pick up a twenty-year-old encyclopedia, you will read in the relevant chapter that you need 120 grams of protein. If you get a later edition, you will read: 20 to 50 grams, and if you had more, you would become ill from it. So you see what the situation is with scientific truths. We are taught what is to be considered true or false depending on which edition of the encyclopaedia we get hold of. All this just goes to show that you cannot get a clear idea of such things, which go into the spiritual, at all in this way. And that is of course a reason, when one really considers the matter, to go into the spiritual, when one wants to understand what happens when man takes in egg white. But it is that food, which must still be processed in the intestines, in the abdomen, and the abdomen itself must have the strength to process this egg white. You know that protein, especially fresh egg white, is semi-liquid. All protein is semi-liquid. The human etheric body has access to all semi-liquid substances. The human etheric body cannot do anything with solid substances, only with liquid ones. So the human being must take all the food he consumes in a liquid state.

Now you will say: When a person takes salt, sugar or something like that, it is solid. But it is immediately dissolved! That is what the saliva is for. The solids that make up the actual physical body must not enter the human body from the outside world at all. Therefore, you can conclude: You have solids in you, you know that; the bones are solid. But the thing is this: The firm bones are formed only out of the fluids in the human body itself. Nothing solid from the outside can ever enter the human body. The human body must allow everything solid to arise from the fluids. Therefore, you can say: We have the solid in us and the physical body forms it. But the physical body is formed entirely out of the liquid, and for the liquid, the etheric body is there, the fine body that cannot be seen, but which permeates the whole human being. And the egg white must also be completely processed by the etheric body, in the lower abdomen. Of course, as I have already told you, the other spiritual elements of the human being also work in there; but the egg white must be processed in the etheric body. So the fluid is there for the etheric body of the human being. Now, from the fact that you can know that the egg white must be processed in the human abdomen, you can see that the egg white cannot actually do the very hardest work in the human being, because it does not need to work its way up into the thoracic body, and above all, it does not need to work its way up into the human head. You see from this that egg white cannot serve as a nutrient that comes into consideration in the first place. One could say that it is actually impossible for a person to eat too little protein, because in the abdomen, what one eats is immediately inside; it does not need much work there. The protein is processed in the abdomen. Even if a person only consumes food that is very low in protein, all protein is processed immediately.

So you can see that it is entirely possible for humans to get by on a low-protein diet. Today, science already admits that, but years ago, children in particular were overfed with protein. Today, we see the children who were overfed with protein in the 1870s or 1880s; they now suffer from hardening of the arteries or have already died from it. So the harmfulness of something does not become apparent in the same period of time, but only much later.

The second type of food is fat. Fat naturally goes into the abdomen when it is eaten. But fat passes through the intestines and has a very strong effect on the middle part of the human body, on the chest. So for the middle part, the thoracic region, for the proper nourishment of the heart, chest and so on, humans must take in fatty substances.

From this it follows that man needs fat in the thoracic region because breathing takes place in the thoracic region. What does that mean? It means that the carbon that humans carry within them combines with oxygen. When carbon combines with oxygen, warmth is needed. The function of fats, in combining with oxygen, is to produce warmth. So fats contribute greatly to what the human chest organism needs.

Now one can say: proteins, when not processed by the body, and specifically when not processed in the abdomen, have a tendency to rot. If we have proteins in us that cannot be properly processed, we really do have something like rotten eggs in our intestines. Isn't that right, gentlemen? You are well aware of the smell of rotten eggs, and the thing is that if a person takes too much protein, he sweats this rotten-egg smell out internally into his body. He permeates himself completely with this rotten egg stench. Yes, if you leave eggs standing, then they will become rotten eggs, then they will stink like rotten eggs. And the part that the body has not processed will of course also stink in the body; but the other part, which is processed, will not stink, but will be transformed into something pure in the body. But that is the work of the etheric body. The etheric body is there to overcome and eliminate that which arises as a putrid stench. It is the case in the human body that the etheric body is the fighter and the victor over putrefaction. Putrefaction is conquered in the human being through the etheric body. If a person no longer has their etheric body after death, then they begin to rot. So I would like to say quite tangibly here: a person does not rot while they are alive; as soon as they are no longer alive, they rot. Why is that? Because the etheric body is gone when a person is dead! The etheric body is therefore the part of the human being that prevents rotting. So we are constantly fighting putrefaction within us, and the one who fights putrefaction is our etheric body.

So I think, gentlemen, anyone who thinks this through must find with the utmost clarity, merely by external observation, that an etheric body must be there, that an etheric body must be there everywhere at all. Just imagine, proteins are produced everywhere on earth, and they rot. The earth would have to stink up to heaven if it were not for the ether, which repeatedly drives away this putrefaction. So, inside and outside the human organism, it is the ether that constantly fights against the proteins from becoming putrid. This must be taken into account.

If we move on to fats, then we have to say: fats do not go bad, but they do go rancid – you all know this if you have ever left fats out somewhere – even butter goes rancid. So fats have the peculiarity of going rancid. Now, if you have left butter standing, you won't be able to tell whether it's rancid or good, fresh butter — unless you're trained to look at it. But when you put the butter on your tongue and taste it, you know immediately that the butter is rancid. So it has something to do with consciousness, with sensation. Rotting has something to do with smelling, with the external, you can smell it. Of course, it is different with rotten eggs than with the scent of roses, but at least you smell it. But not the process of going rancid. Rancidity is something that is described in terms of something more internal, of tasting.

This already indicates that it has much more to do with inner sensation than with what is putrid about eggs. The human thoracic body is physically connected to all that is sensation in consciousness, but the astral body is spiritually connected to it. And you know that what is air-like is in the thorax. We breathe in the air. We process the air. In the chest, the air is in the right place. In the other part of the human body, only a small amount of gases and air types may be produced. If too much gas is produced in the intestines, it causes bloating, and that is not healthy. The middle body of the human being is there for the actual gas production. And the higher supersensible spiritual link that intervenes there — that intervenes in the gaseous — is the human astral body. This human astral body now fights the rancidity of fats within itself; just as the etheric body fights the putrefaction of proteins, so the astral body fights the rancidity of fats. Man would constantly have a rancid belching of his own fats, would taste rancid inside, if his astral body did not constantly fight this rancidity. So that we have this astral body within us to fight the rancidity of fats.

You see, gentlemen, that is quite wonderful, because you can see from it that what is outside in the ordinary physical, material world takes a completely different course from what is inside with us. Outside in the physical world, fats definitely go rancid. Man does not always go rancid for his own good, only when he becomes ill inside. So the thing is that in a healthy state, a person's astral body is such that it cannot go rancid. It only goes rancid if the person eats too much fat for the astral body to cope with, or if too much fat is produced due to some other reason. But internally, the person does perceive when their fat is going rancid. And one can say: When a person becomes very rancid, that is, when the activity of the astral body is much too weak, then he has an unpleasant taste in his mouth all the time. This unpleasant taste then has an effect on the stomach. And in this roundabout way, a person first gets stomach and intestinal diseases from the rancid fat within himself.

If you notice that a person is becoming rancid inside, then arsenic is a good remedy for the fats that he has inside that he is not processing. Arsenic fights against fattening and strengthens the astral body. And the result is that the person can fight this rancidity. These are things that are extremely important. If a person shows an inclination within themselves to be unable to overcome their putrid protein through the etheric body, then some compound with copper usually has an extremely strong effect on the person as a remedy. Copper is effective when the lower abdominal diseases, intestinal diseases, are directly caused by the protein. But if you notice that something is making itself felt through the mouth, through the sense of taste, it does not help to give the person copper, but arsenic is needed because you first have to strengthen the astral body. So it is not enough to simply state that this or that disease lies in this or that part of the human being; instead, one must know where they come from. Whether they come from rotten protein in the intestines or from fats that have gone rancid, which in turn affect the intestines and stomach through the taste of the mouth.

So you see, gentlemen, we have within us the opposite of what these substances show on the outside. We have an astral body that fights the rancidity of fats, whereas in the ordinary physical material world, fats simply go rancid.

A third food that humans consume is the substances that are carbohydrates. Carbohydrates are found in particular in potatoes, for example, in lentils and beans, and of course in all types of grain. The carbohydrates are in there. In a great many of these substances, either sugar is directly contained, which we always take with our food, or sugar is produced directly from these carbohydrates by converting what we take in with the potato, for example. Potatoes contain mostly starch. This starch paste is first converted into dextrin and then into sugar in our bodies. So when you eat potatoes, you are actually nourishing yourself with sugar, because the potato paste, the starch paste, is converted into sugar in the human body. Isn't it true that grapes, for example, contain a lot of this sugar, and so does alcohol. What alcohol is for a person is actually based not only on the alcohol itself but also on its sugar content. Sugar is produced in the human organism from alcohol.

The first kind of food was therefore protein, the second kind was fat and the third kind was starch, sugar. We have seen that protein is processed by the etheric body in certain quantities, so that it does not become putrid. The fats are processed by the astral body, so that they do not go rancid. Now for starch and sugar! If you look at the etheric body, you have to say that it is mainly active in the lower body. The astral body is mainly active in the chest area. Now we come to something else. You all know, I don't want to say from your own experience, but from seeing people who are not like you, the effect of alcohol, and you know that alcohol produces a particular characteristic in people, first in the intoxication, but we don't want to talk about that for now. But you know, the next day – we have already spoken about this – the so-called “brummschädel” (headache) comes, it is also called a hangover. What does the headache or hangover mean?

Yes, gentlemen, you will already have gathered from the name that a headache has something to do with the human head. And if you have heard people describe how they were different from you the next day because they had a little too much to drink the day before, you will have heard them complain mainly about their heads. Their heads hurt, and when they don't hurt, they feel like they might fall off their shoulders and the like. What actually happens then?

The task of the head is namely to fight what starch and sugar want. What do starch and sugar want? You only have to look at wine. Isn't it true that when autumn comes, you harvest the wine, the grapes. They are pressed and then the mixture ferments. What is left after the process is enjoyed as wine. Now, because wine has become wine through fermentation, it has overcome fermentation. But when you bring wine into the stomach, something is created from it that in turn goes into the food. The alcohol is almost transformed back. And now the substances that want to ferment directly are starch and sugar. Starch and sugar in the human organism want to ferment. When you drink alcohol, the alcohol in the head drives away the forces that prevent the fermentation of sugar and starch in the human body. Let's take the story very clearly. Say you ate potatoes and beans on January 22nd and drank alcohol with them. Well, if you hadn't drunk alcohol, your head would have stayed sober. Potatoes and beans contain starch and sugar, which is produced from the starch; the head would have the power to properly prevent the fermentation of starch and sugar. If you take alcohol, the head loses the ability to prevent the fermentation of starch and sugar that you have taken in with the potatoes, and the potatoes and beans, and also the other things, cereals for example, begin to ferment in you.

So instead of preventing fermentation in the human being, it now occurs. And it occurs through an inability of the head that has occurred as a result of alcohol, so that the person is now full of fermentation. There is a strange expression in central Germany, in Thuringia. When someone talks nonsense, they say in Thuringia: He is fermenting. In these parts, it is not customary to say that someone who talks nonsense is fermenting; but those who have been to Germany will have heard it said in central Germany. And if someone always talks nonsense, then in central Germany, in Thuringia, they call him an old hag. So the thing is that in central Germany, fermenting is associated with being confused in the head, with talking nonsense. That is a very good folk instinct. You know that there is too much ferment in a person when they talk too much nonsense. Now, if someone has drunk alcohol and has a headache, then he does not talk nonsense, because he becomes quiet, but the nonsense is in him, it rumbles in him. So it is something that occurs to prevent starch and sugar from fermenting, something that counteracts the tangible effect of alcohol. So that one can say: There is something in the human mind that constantly works to prevent the starch and sugar in it from fermenting.

Now, no one denies that the human head is home to the strongest I, just as the abdomen is home to the etheric body and the middle body to the astral body, the I, the actual I. It is now the case that this actual I has to do with the warmth, just as it has to do with the solid of the physical body, with the liquid of the ether body, with the gaseous of the astral body. It is the case that in everything that depends on the actual self, the human being sets warmth in motion. This can be traced in the human body down to the last detail. The actual self is also connected with the blood, which is why the blood generates warmth. But the actual self, that which the human being experiences in consciousness, is also connected, for example, with glandular secretion. Therefore, glandular secretion is now associated with warmth. It is also the real self that now prevents fermentation from the supersensible through the powers of the head. So one can say: the etheric body fights the putrefaction of the proteins, the astral body fights the rancidity of the fats, the I fights the fermentation of sugars and starches.

This is also the reason why I had to tell you that excessive consumption of potatoes is bad for the head. Excessive consumption of potatoes has the following effect on people. You see, potatoes contain little protein. Because they contain little protein, they are actually a good food for humans. And if a person eats potatoes in moderation with other foods, then it is a good food because of its low protein content. But the potato contains an extraordinary amount of starch, which has to be converted into sugar in the human body, first into dextrin and then into sugar. I told you at the time that if a person eats too many potatoes, his head has to work terribly hard; of course, because the head has to prevent the fermentation. That is why people who eat too many potatoes and therefore have to work their heads terribly to process the potato fermentation become weak-headed. In particular, the middle sections of the brain become weak; only the frontal sections of the brain, which do not have to work as hard to prevent potato fermentation, remain. And so it is precisely because of the fact that potato food has become widespread in recent times that materialism has come about, because it is produced in the forebrain.

It is so strange: one believes that materialism is a logical thing. In a way, materialism in modern times is nothing more than the result of eating potatoes! Well, it's not true, people don't like to think that they should live on potatoes alone; but then they like materialism. So they are actually in a contradiction. If you really wanted to be a materialist, you would actually have to advise spreading potato food everywhere, because it would be the best way to become convinced of materialism, wouldn't it? That is something that most people don't succeed at. But if the materialistic monists wanted to fight effectively, they would actually have to ensure that other foods are replaced by potato foods as much as possible. Then the Monist League would achieve quite tremendous successes. If it did not work very quickly, it could work best over a period of several decades, and it would have the best possible results if it tried to influence people to eat only potatoes. But the people on whom it wanted to exert an influence would have a few tricks up their sleeves to get around its efforts, so it would not have the best possible success!

But you can see from this that spiritual science, as practised here, recognizes precisely the right kind of materialism. Materialism knows nothing at all about the material; spiritual science recognizes precisely that the potato is the right producer of materialism. It is terribly insidious, the potato, cunning, clever to excess. For just see, man can only eat the tubers of the potato, not even the eyes on the potato – they are harmful in themselves – and he certainly cannot eat the flower, because the potato is a member of the nightshade family and the flowers are poisonous. But what is the poison? I already told you last time: in large quantities the poison kills, in small quantities, finely distributed, it is a remedy. The potato itself has a great deal of starch paste in it, it consists almost entirely of starch paste. It could not live because the starch paste would be terribly harmful; at the same time, it draws the poison out of the world and destroys the harmful effect in itself. That is why I call her clever and cunning. She herself has her poison, through which she removes the harmfulness for herself. But the poison of the potato is particularly harmful to humans; she does not give that to him, she only gives him what she herself combats in herself through her poison. It is really something that can be called that: the potato is a clever, cunning creature! And humans must be clear about the fact that if they eat too many potatoes, their midbrain will atrophy and that even their senses can suffer precisely from excessive potato consumption.

If you eat too many potatoes as a child or very young person, your midbrain will become extremely weak. But the midbrain contains the sources of the most important sensory organs. The midbrain contains the four-mound body, the visual mounds and so on, and excessive potato consumption can even weaken vision because it has its sources in the midbrain. And some eye diseases in old age are caused by the fact that a person was raised on too many potatoes as a child. The person then becomes visually weak, weak-eyed. It is really the case that in the past, people in Europe became visually weak much less often in old age than they do now. And that in turn stems from the fact that, in addition to what otherwise affects the eyes – but that does not even have such a strong effect because it does not work internally, electric light and so on – the excessive consumption of potatoes has a very harmful effect on the eyes, on vision and even on the sense of taste – even on the sense of taste! You see, that is where the following comes from. Suppose a person eats too many potatoes from childhood on. You will often see this in later life: the person never knows when he has had enough because his taste has been spoiled by eating too many potatoes. In contrast, a person who has not eaten too many potatoes knows instinctively when he has had enough. So the instinct, which is more tied to the midbrain, is spoiled by excessive potato consumption. This is what has emerged particularly strongly in recent times.

But from all that I have told you, you can see that a person must be particularly careful to be strong enough to overcome, firstly, the decomposition of proteins, secondly, the rancidity of fats, and thirdly, the fermentation of starch and sugar.

Now, as I told you last time, a person cannot be completely teetotal, because if he does not drink any alcohol at all, alcohol is produced in him. But this alcohol remains in the abdomen; it does not go up to the head, because the head must be free of alcohol, otherwise it is immediately unable, as the carrier of the ego, to fight the fermentation that is in the body in the right way. You see, now you can form an idea of the way in which man relates to his natural environment. If you look, for example, at the protein that is rotting everywhere – after all, animals and plants are rotting – you have to say: there is ether everywhere, which gradually balances this out. If you look at the fats, which are also in the plants and are everywhere, you have to say that these fats would gradually make all living things incapable of living, both animal and human, if it were not for a fighter against rancidity in the astral body. So, in fact, the human being fights that which is outside in nature. And when the human being dies, the etheric body, the astral body and the ego leave the physical body. The human being then passes over into the spiritual world. What happens then? Well, gentlemen, you know what happens. The corpse immediately begins to decompose, to go rancid and to ferment at the same time, except that the decomposition is of course more visible, or rather more noticeable, because people rarely walk around with their noses stuffed up. So the putrefaction is easily smelled. But somehow lying over a grave and tasting whether the fat of the corpse in question has gone rancid is not something one usually does, and that is why one usually knows nothing about it. And the fermentation that does take place is certainly not studied. So it is actually the case that when the ego departs, the human body begins to ferment; when the astral body departs, the human body begins to go rancid; and when the etheric body departs, the human body begins to rot. Man carries this within him continually, but while he lives on earth, he fights it continually. Anyone who denies that the etheric body, the astral body and the I are spiritual realities within the human being must be asked: what do you think actually happens, why does the human being not rot? Why does he not ferment? Why does he not turn rancid? He would have to do so if he were like the mere physical body!

But what does our science do? Our science waits with its study until the human being has died. Because what it knows about the living human being is actually very little compared to what it actually knows from anatomy when the human being is a corpse, has died. Everything you can actually learn relates only to the corpse. Our science always waits for the corpse. So this science cannot know anything at all about the real human being who is alive, because it does not take this human being into account at all. And that is precisely the damage to our science – it has only been like this since the 17th century – that it has basically only gained its knowledge from the corpse. But the corpse is no longer the human being, because one must ask: What is it that, while the human being is alive, the corpse, which he also carries with him during his lifetime, does not behave as a corpse in such a way that it rots, ferments and becomes putrid? It is precisely when one really looks at the living human being that one comes across these spiritual, these supersensible aspects of the human being. And then one also notices that the ego works primarily in the head, that the astral body works primarily in the chest, and that the etheric body works primarily in the lower body. And science does not even know about the lower body, because it believes that the same processes that are outside in nature are in the lower body. That is simply not the case.

Well, gentlemen, it is interesting to study things, I would like to say, not in the study chamber, but to study them in the life of the people outside. There are, as you know, baths where it smells of rotten eggs, for example Marienbad. There are also German baths that contain hydrogen sulfide, where it smells like rotten eggs. Yes, really: people who are otherwise gourmets and also have a fine sense of smell have to go to such bathing places. And why do they do that? Why do they sometimes live there for several months during the summer in places where it smells as if everything has been sprinkled with rotten eggs? You see, it is like this: these people have actually eaten too much protein, and now they come to the seaside resort; because they are covered with skin and the thing is internal, they themselves do not smell like that, but if you could smell it, they would smell terribly of rotten eggs inside! Now all these people, who smell of rotten eggs on the inside, come to the seaside resorts, where it smells of rotten eggs, and what happens there? Yes, you see, one time the rotten egg smell is inside, the other time it is outside. The first time it is inside, the nose does not notice it; the second time it is outside, the nose notices it. Head and stomach are opposites. What the stomach produces in terms of rotten egg smell when it comes from the head through smelling is fought. And so, in the seaside resorts that smell of rotten eggs, the internal rotten egg smell is fought.

This is especially noticeable for those who have the sense to make such observations. As a boy, I happened to go to a seaside resort like this. I had to go to Bad Marienquelle every other day. So it stinks of rotten eggs there. While it is so unpleasant on the outside because it smells so terrible, you suddenly start to feel very comfortable in your stomach. So if you are not sick, if you don't have a rotten egg smell in your stomach, you experience a feeling of a higher zest for life. Those who do not let themselves be repelled by the rotten egg smell can experience this. Of course, the one who holds his nose shut does not have the opposite, does not have this spring effect in the stomach that one has when one really surrenders to the rotten egg smell. And the rotten egg smell, for example, even when artificially produced, is an extraordinarily good healing agent. It gives the body the strength, for example, to make fading muscles firm again, to make them strong. Now, people do not love such cures, but they are extremely useful in a certain respect. Because, you see, when the rotten egg smell approaches a person externally, it becomes spring in the belly internally. And in spring everything sprouts and grows, and a person can become strong again by getting spring in his belly.

This is what happens to people who gluttonously spoil their stomachs during the winter. You see, if you don't spoil your stomach in winter through gluttony, then you join in with the spring that is outside. It is precisely the abdomen that participates in spring in an extraordinarily strong way. But if you really want to experience spring outside in nature, then you should eat as few such things as goose liver pâté and so on as possible. If you have eaten a lot of goose liver pâté, then it is not spring in the human stomach, but rather it remains in the human stomach as it is under the earth in winter - not as it is on the earth, but as it is under the earth. It is warm there, that is where you put the potatoes in the pits. But everything in the person rots because the warmth is stored in the belly; it does not spring in the person. And then you have to look for an artificial spring in the rotten egg smell.

Such is the contrast between the ego and the etheric body. The I and the etheric body must balance each other out in the human being. You can see from this that if you only really study nature, if you go to a seaside resort with an open mind and there is a rotten egg smell, hydrogen sulfide, then the feeling of spring in the belly teaches you how the opposite of this actually works internally in the putrefaction of the protein substance.

I wanted to give you some additional information to what I said last time. You know that I told you that when someone has taken a certain poison, they must take liquid egg white as an antidote. Those things that are healthy become poisons if they are not properly treated in the body, if too much of them enters the body. So even egg white can expel a toxin from the human body, but egg white itself is toxic if it decays in the body, if too much of it enters the body. So close together are nutrition and poisoning. And you will have heard for yourself how excess in nutrition can become poisoning. A large part of illnesses are nutritional illnesses, that is, no consideration is given in nutrition to the fact that the substances in question should only be consumed in a certain amount if they are to be processed.

I will have the next lesson announced because I cannot be there on Saturday. I will be in Bern.
