The Marvelous World of Dietary Fiber ( englisch )

The Marvelous World of Dietary Fiber:

Its Types, Importance for Health, and the Role of Gut Bacteria

Dietary fiber plays a crucial role in our nutrition and overall health. These fiber-rich nutrients are found in various foods.

Here are some examples:

Whole grains such as whole grain bread, pasta, and rice, as well as quinoa, are high in fiber.

Excellent sources of fiber include beans, lentils, chickpeas, and peas.

Among vegetables, we find rich sources of fiber, such as green leafy vegetables like spinach, kale, and Swiss chard, along with many other vegetables like broccoli, carrots, celery, and sweet potatoes.

Further examples of fiber-rich foods can be found in the abundant selection of fruits and berries.

This includes apples, pears, bananas, oranges, plums, and avocados.

Examples of healthy berries are red and black currants, gooseberries, blueberries, and tomatoes, pumpkins, and zucchini, which are also classified as berries.

Healthy strawberries belong to the nut family.

Nuts and seeds are also an excellent source of fiber.

This includes the aforementioned strawberries.

Other examples from this outstanding food group include almonds, walnuts, chia seeds, flaxseeds, pumpkin seeds, and hemp seeds.

In this article, I will discuss the various types of dietary fiber, their importance for health, and the vital role that gut bacteria play in processing fiber.

Types of Dietary Fiber:

Soluble Fiber:

This type of fiber dissolves in water and forms a gel-like substance. It is found in foods such as oats, legumes, apples, and carrots.

Insoluble Fiber:

This fiber does not dissolve in water. It helps increase stool bulk and supports gut health. Foods such as whole grains, vegetables, and nuts contain insoluble fiber.

The Importance of Dietary Fiber for Our Health:

Digestive Promotion:

Dietary fiber promotes healthy digestion by regulating bowel movements and preventing constipation.

Blood Sugar Control:

Soluble fiber can help stabilize blood sugar levels by slowing the absorption of sugar.

Cholesterol Reduction:

Fiber binds to bile acids in the intestines and promotes their excretion, which can lead to a decrease in cholesterol levels.

Weight Management:

High-fiber foods provide a longer-lasting feeling of fullness and can help control weight or even support weight loss.

The Role of Gut Bacteria

Gut bacteria play a crucial role in processing dietary fiber. These beneficial bacteria ferment fiber in the colon, producing short-chain fatty acids such as butyrate, propionate, and acetate.

These short-chain fatty acids play an essential role in the human body, particularly in the digestive tract.

Energy Metabolism:

These fatty acids are used by the gut cells as an energy source. They are needed for various metabolic processes and the production of enzymes.

Butyrate is the preferred energy source for colon cells and helps maintain a healthy gut barrier.

Anti-Inflammatory Effect:

Short-chain fatty acids have anti-inflammatory properties and can reduce the expression of inflammation. Lower inflammation in the body can help regulate the activity of enzymes involved in inflammatory responses, thereby contributing to the prevention of inflammatory bowel diseases.

Gut Health:

Butyrate, as one of the most important fatty acids, is used by gut cells as a preferred energy source.

Propionate and acetate help maintain a healthy gut flora and function.

They support the integrity of the intestinal lining and contribute to regulating bowel movements, promoting digestion and nutrient absorption.

Immune System Regulation:

These fatty acids work with the immune system to help maintain an appropriate immune response by influencing the activity of certain immune cells. This contributes to disease defense and maintains an optimal environment for the body's enzymatic reactions.

Although short-chain fatty acids are not directly involved in enzyme formation, they can still influence enzyme activities by regulating various metabolic and immune responses that are crucial for the body's health.

Metabolic Health:

Short-chain fatty acids can regulate metabolism and improve insulin sensitivity, reducing the risk of metabolic disorders such as diabetes.

Overall, dietary fiber and the short-chain fatty acids produced by gut bacteria are crucial for the health of the digestive system, metabolism, and immune system.

By consuming a fiber-rich diet, we positively influence our health.

In our nutrition, dietary fiber plays a crucial role in our health. These fiber-rich nutrients are contained in a variety of foods

Species-appropriate nutrition( Englisch)

What Is Species-Appropriate Nutrition?

How Our Ancestors' Diet Can Help Us Live Healthier Lives

Have you ever wondered if our modern eating habits are truly the best for our health? The concept of "species-appropriate nutrition" is gaining more and more attention, with many people seeking ways to improve their well-being.

But what does it actually mean? And why should we care about it at all?

What Is Species-Appropriate Nutrition?

To understand it better, we look at what our ancestors ate. The concept of species-appropriate nutrition is based on the idea that our bodies have adapted to certain types of food over the course of evolution. This means that some foods are better suited to our biological needs than others.

The Diet of Our Ancestors

When we take a look into the past, we see that our ancestors' diet was much simpler than the one we follow today. They mainly ate unprocessed foods, such as vegetables and fruits (referring to ancient varieties), along with nuts and seeds. Fish and meat were also an essential part of their diet, as they were hunters and gatherers.

These foods were rich in proteins, fats, carbohydrates, vitamins, bioflavonoids, and minerals. (Back then, the content of the last three in food was much higher than it is today.) In short, they had everything the body needs to stay healthy.

What Can We Learn from This?

By adopting some of the eating habits of our ancestors, we can likely improve our health. Instead of relying on processed foods, which are often linked to various health problems, we should aim to consume a variety of unprocessed foods. This doesn't mean we need to completely abandon modern foods, but we should try to source the majority of our diet from natural, whole foods.

Conclusion

The idea of species-appropriate nutrition might seem complicated at first glance, but at its core, it's about listening to the needs of our body and giving it what it can best process. By aligning our diet more closely with that of our ancestors and incorporating a wide range of unprocessed foods, we can improve our health and feel better.

It's never too late to start. So why not begin today? Your body will thank you

Excess protein and carbohydrates ( englisch )

The Silent Danger: How Diet, Excess Protein, and Carbohydrates Can Contribute to Insulin Resistance

In today’s world, our eating habits are under constant scrutiny – and rightly so. In the past, the diagnosis of Type 2 diabetes seemed to be mostly confined to older adults. However, more and more young adults and even children are now being diagnosed with this condition. This alarming trend forces us to rethink our diet and its impact on our metabolism. It’s not just sugar and carbohydrates, which are quickly converted into glucose, that play a role; the amount of animal protein we consume is also significant.

Sugar and Carbohydrates: A Well-Known Culprit

It is well known that sugar and simple carbohydrates – like those found in white bread, sweets, and sugary drinks – are rapidly converted into glucose. These quick blood sugar spikes cause our body to produce more insulin to transport the glucose from the blood into the cells. However, if this process is triggered too often, the system can become overwhelmed, leading to insulin resistance over time. In this state, insulin is no longer able to work effectively because the cells become resistant to the hormone.

The Role of Proteins: More Than Just Building Blocks

While carbohydrates often take center stage as the culprit, another factor is frequently overlooked: proteins. Our body has well-defined storage sites for glucose, such as in the liver, and for fats, in our fat deposits. But where do we store proteins? Scientific speculation suggests that excess proteins may accumulate in the basement membranes of our blood vessels.

These membranes, which act as a barrier between the cells and the blood vessels, can become increasingly impermeable due to protein deposits. This results in elevated blood pressure, as the heart needs to work harder to pump blood through the narrowed vessels. Here, the connection becomes clear: If the basement membranes are less permeable, it becomes more difficult for insulin to transport glucose from the blood into the cells. This marks the beginning of insulin resistance.

The Alarming Increase in Insulin Resistance and Type 2 Diabetes

In recent decades, we have witnessed a dramatic rise in cases of insulin resistance and Type 2 diabetes, particularly among younger people. In the past, this disease mainly affected older adults, but now we see more children and teenagers developing it. But why?

There are two main factors that could be contributing to this trend: our increased consumption of carbohydrates and the drastically higher intake of animal protein. While carbohydrates were consumed in moderation in the past – think of the occasional bread roll or Sunday cake – they now have a permanent place in our daily diets. On top of that, the consumption of meat, sausage, and animal products has increased significantly compared to a few decades ago.

A Look at the Past: What Can We Learn?

When I was a child, food access was quite different in many households. Meat was a rare treat, typically served as a Sunday roast. During the week, there might be a piece of sausage in pea soup or some eggs in mustard sauce – and that was it. Bread was also limited, usually just one slice in the morning and another at dinner, often topped with tomatoes, cucumbers, or radishes. Cookies or cake? Those were reserved for special occasions, like Sundays or holidays. Diabetes was almost exclusively found in older adults or in wealthier households.

Today, we and our children eat far more carbohydrates and animal protein than back then. It seems these two factors play a critical role in the increasing prevalence of diabetes.

Conclusion: Balance in Diet Is Key

Modern diets present numerous health challenges, and both an excess of carbohydrates and animal protein appear to contribute to the development of insulin resistance and diabetes. Therefore, it is essential to find a healthy balance in our diet. A diet rich in fiber, healthy fats, and moderate amounts of protein, combined with regular exercise, is the key to maintaining stable blood sugar levels and staying healthy in the long run.

Perhaps our ancestors intuitively understood what scientific research is confirming today: Less is often more, and a balanced diet can be the best protection against the silent dangers of our modern eating habits.

Proteinüberschuss und Kohlenhydrate

 Die stille Gefahr: Wie Ernährung, Proteinüberschuss und Kohlenhydrate zur Insulinresistenz beitragen können

In der heutigen Zeit stehen unsere Essgewohnheiten unter ständiger Beobachtung – und das zu Recht. Früher schien die Diagnose Diabetes Typ 2 fast ausschließlich älteren Menschen vorbehalten zu sein, doch mittlerweile sind es immer mehr junge Erwachsene und sogar Kinder, die an dieser Krankheit erkranken. Es ist eine alarmierende Entwicklung, die uns zwingt, unsere Ernährung und deren Einfluss auf den Stoffwechsel neu zu überdenken. Dabei spielen nicht nur Zucker und Kohlenhydrate, die schnell in Glukose umgewandelt werden, eine Rolle, sondern auch die Menge an tierischem Protein, die wir konsumieren.

Zucker und Kohlenhydrate: Ein bekannter Übeltäter

Es ist weithin bekannt, dass Zucker und einfache Kohlenhydrate – wie in Weißbrot, Süßigkeiten oder zuckerhaltigen Getränken – schnell in Glukose umgewandelt werden. Diese schnellen Blutzuckerspitzen führen dazu, dass unser Körper verstärkt Insulin produziert, um den Zucker aus dem Blut in die Zellen zu transportieren. Doch wenn dieser Prozess zu oft angeregt wird, kann es zu einer Überforderung des Systems kommen, was langfristig zur Insulinresistenz führt. Dabei kann das Insulin seine Arbeit nicht mehr effektiv verrichten, da die Zellen unempfindlich gegenüber dem Hormon werden.

Die Rolle von Proteinen: Mehr als nur ein Baustoff

Während Kohlenhydrate als Übeltäter oft in den Fokus rücken, bleibt ein anderer Faktor häufig unberücksichtigt: die Proteine. Unser Körper hat gut definierte Speicher für Glukose, wie in der Leber, und für Fette, in unseren Fettdepots. Aber wo speichern wir eigentlich Proteine? Wissenschaftliche Vermutungen deuten darauf hin, dass überschüssige Proteine sich in den Basalmembranen unserer Blutgefäße einlagern könnten.

Diese Membranen, die als Trennschicht zwischen den Zellen und den Blutgefäßen dienen, können durch die Einlagerung von Proteinen zunehmend undurchlässiger werden. Dies hat zur Folge, dass der Blutdruck steigt, weil das Herz mehr Kraft aufwenden muss, um das Blut durch die verengten Gefäße zu pumpen. Und hier schließt sich der Kreis: Denn wenn die Basalmembranen weniger durchlässig sind, wird es auch für das Insulin schwieriger, die Glukose aus dem Blut in die Zellen zu transportieren. Der Beginn der Insulinresistenz ist gemacht.

Die alarmierende Zunahme von Insulinresistenz und Diabetes Typ 2

In den letzten Jahrzehnten haben wir einen dramatischen Anstieg der Fälle von Insulinresistenz und Diabetes Typ 2, insbesondere bei jüngeren Menschen, beobachtet. Früher betraf diese Erkrankung vorwiegend ältere Menschen, doch nun sehen wir, dass immer mehr Kinder und Jugendliche betroffen sind. Aber warum?

Es gibt zwei Hauptfaktoren, die zu dieser Entwicklung beitragen könnten: unser veränderter Konsum von Kohlenhydraten und die enorm gestiegene Aufnahme von tierischem Eiweiß. Während Kohlenhydrate früher in Maßen verzehrt wurden – man denke an die seltenen Brötchen oder den Sonntagskuchen – haben sie heute einen festen Platz in unserem täglichen Speiseplan. Dazu kommt die Tatsache, dass Fleisch, Wurst und tierische Produkte heute in weitaus größeren Mengen konsumiert werden als noch vor einigen Jahrzehnten.

Ein Blick in die Vergangenheit: Was können wir daraus lernen?

Als ich ein Kind war, gab es in vielen Haushalten einen ganz anderen Zugang zu Nahrungsmitteln. Fleisch war eine seltene Delikatesse, die höchstens am Sonntag als Braten auf den Tisch kam. Unter der Woche gab es vielleicht mal ein Stück Wurst in der Erbsensuppe oder Senfeier – das war’s. Auch Brot war in der Menge begrenzt, meist gab es morgens eine Scheibe und abends eine weitere, oft belegt mit Tomaten, Gurken oder Radieschen. Kekse oder Kuchen? Diese waren nur für besondere Anlässe wie Sonntage oder Feiertage reserviert. Diabetes war in dieser Zeit fast ausschließlich bei älteren Menschen oder in sehr wohlhabenden Schichten verbreitet.

Heute essen wir und unsere Kinder deutlich mehr Kohlenhydrate und tierisches Eiweiß als damals. Es scheint, dass diese beiden Faktoren eine entscheidende Rolle in der zunehmenden Verbreitung von Diabetes spielen.

Fazit: Die Balance in der Ernährung ist entscheidend

Die moderne Ernährung bringt zahlreiche gesundheitliche Herausforderungen mit sich, und sowohl ein Übermaß an Kohlenhydraten als auch an tierischem Eiweiß scheint zur Entstehung von Insulinresistenz und Diabetes beizutragen. Es ist daher essenziell, ein gesundes Gleichgewicht in unserer Ernährung zu finden. Eine ballaststoffreiche Ernährung, gesunde Fette und Proteine in Maßen, kombiniert mit regelmäßiger Bewegung, sind der Schlüssel, um den Blutzuckerspiegel stabil zu halten und langfristig gesund zu bleiben.

Unsere Vorfahren haben vielleicht intuitiv gewusst, was wir heute erst durch wissenschaftliche Erkenntnisse bestätigen können: Weniger ist oft mehr, und eine ausgewogene Ernährung kann der beste Schutz vor den stillen Gefahren unserer modernen Essgewohnheiten sein.

Managing blood sugar levels (Englisch)

How the Order of Our Food Intake Affects Blood Sugar Levels

CO₂ is essential for life on Earth. It forms the basis of photosynthesis, a process that plants use to create glucose from carbon dioxide (CO₂), water, and sunlight. Glucose, a form of sugar, is the starting material for producing starch and cellulose, the building blocks of plants. Without this process, neither plants nor animals, including humans, could exist.

But what does this mean for our diet and the effects of sugar on our bodies?

The Impact of Sugar and Fruit on Blood Sugar Levels

Fruit naturally contains high amounts of sugar, especially fructose, which often leads to a rapid rise in blood sugar levels after consumption. This spike triggers a strong release of insulin, the hormone responsible for transporting sugar from the blood into cells, where it is either used for energy or stored as fat.

To avoid sharp fluctuations in blood sugar levels and excessive insulin release, the order in which we consume certain foods plays a crucial role.

The Order of Food Intake: A Key to Blood Sugar Control

By eating fiber-rich foods before consuming protein and sugar-rich foods, we can better regulate blood sugar. Here’s how it works:

• Fiber First: Starting with fiber-rich foods slows down digestion and sugar absorption in the intestines, resulting in a slower release of sugar into the bloodstream and preventing sharp blood sugar spikes.
• Proteins and Fats After: Proteins (e.g., meat, fish, eggs) and healthy fats (e.g., from nuts, avocados) also help regulate blood sugar. They further slow down sugar absorption, allowing for a more even release of sugar over time.
• Carbohydrates Last: Sugar-rich foods, including fruits, should be consumed at the end of the meal. This ensures that the sugar enters the bloodstream more slowly, avoiding sudden insulin spikes.

The Process in the Body: Why This Order Matters

If we eat sugar-rich foods like fruit or sweets first, the sugar is quickly converted into glucose and rapidly enters the bloodstream. The body responds by producing insulin to transport the sugar into the cells. However, excess glucose, which is not immediately needed, is converted into fat, leading to weight gain over time.

When we eat fiber first, it slows down glucose absorption, resulting in a slower, steadier rise in blood sugar. This gives the body more time to convert glucose into energy rather than storing it as fat. Less insulin is released, and energy needs are better met.

Conclusion: The Right Order Makes the Difference

To minimize blood sugar fluctuations and stabilize insulin levels, we should start our meals with fiber-rich foods, followed by proteins and fats, and save carbohydrate-rich and sugary foods for last. This simple adjustment can lead to better blood sugar control and a healthier lifestyle in the long run.

Remember: No matter what you eat—always start with fiber.
