Old friends have heard of Inuit . They are traditional nomads, mainly hunting and gathering food.
Most of them live near the Arctic, and the environment has also created the traditional diet structure of the Inuit people. They mainly eat meat, including land and ocean mammals, such as reindeer , musk ox , seals, whale and fish.
No vegetables, no fruits.
This pure meat diet has been eaten for hundreds of thousands of years. The meat is usually eaten raw, occasionally frozen, dried, fermented or cooked.
This dietary method that highly relies on animals has a characteristic, that is, has no dietary fiber.
This is very inconsistent with modern intestinal nutrition. Without dietary fiber, how can we maintain intestinal health? How do they poop? Will be constipated all year round?
In this article today, let’s discuss and study the intestinal health problems of Inuit people.
Inuit intestinal health, less inflammation
"Science" found that this adaptive diet structure (based on fish and marine mammals) caused Greenland Inuit to undergo gene mutation .
Although Inuit people consume a lot of fat, they suffer from cardiovascular disease and diabetes may have less sex, and their body and intestines are also healthy .
Harvard an anthropologist Stanfinsen When living near Arctic Circle , he found that the intestinal inflammation of Inuit people has a low incidence of , and also poops normally, and there is no problem of long-term constipation.
In addition, during a survey by the famous dentist Western Price in Africa, he found that Maasai is almost pure meat diet, does not have much fiber, and does not have any problems with constipation.
Differences between Inuit and Modern Human Intestinal Human
Human Intestinal Microbiome is a very complex ecosystem, a diverse community composed of eukaryotic microorganisms, viruses, Archaeophytes and most bacteria, and plays an important role in in immunity, metabolism and nutrition.
microbial structure is determined by many factors, including geography, gender, host genetics and age, but it will also change through acquired diet habits.
Most humans have intestinal bacterial flora , which is relatively stable, but may also change with time and dietary style .
There are some studies comparing the microbiome of modern humans with the microbiome of agricultural or hunting tribal populations.
Short-term consumption of animal-rich diet (composed entirely of animal products) can change the intestinal microbiome, increase the number of Bacteroides, Cholephila , etc., while reducing the number of polysaccharide degradation of Firmicutes phylum .
Inuit people living in the Arctic region of are highly dependent on animal foods and belong to a typical low-carb and low-fiber diet.
A sample of 19 adults (16 Inuit, 2 European ancestry and 1 mixed ancestry) from the Canadian Arctic community ( Nunavut region ), and 26 European ancestry adults from Montreal (temperate metropolitan area).
compared intestinal microbial diversity and colony composition characteristics feces.
Most participants from the Arctic community adhere to traditional Inuit diet , and often eat raw foods, especially marine mammals.
study defines traditional diet as a diet of traditional meat, , which does not exclude the consumption of imported or packaged foods.
Three participants who never or only occasionally consumed the traditional Inuit diet (once a week or less), as well as participants from Montreal, were classified as the modern western diet.
According to the sample, the changes in microbial community vary from individual to individual ( 45-61% variation, depending on the beta diversity indicator used), and the variation is very small (3-5%) .
Continuous sampling throughout the year showed that diet caused changes in microbial communities among all participants, especially for Inuit participants with 17% changes.
Compared with Montreal, the composition of the traditional Inuit people, intestinal microbiome, diversity has a great influence.
A single diet affects intestinal diversity, which is normal, which is different from whether the intestine is healthy.
In fact, a habit of the Silver Newts makes their gut very healthy.
Inuit people love to eat fermented food
fermented food is a major part of human diet. Traditional Inuit people will also eat many fermented meat products.
Inuit people will make homemade fermented animals' food, most of which are concentrated on fermented walruses (igunaqs) and fermented seals and whales.
occasionally fermented, some trout , arctic char, narwhal and reindeer.
These aged foods usually do not add salt, use any starter, and do not directly control the temperature. These foods are basically made in the natural environment of .
This fermentation process will expand the diversity of microbials.
Studies have found that in the animal-derived foods fermented by the Inuit, microorganisms are very rich, and these foods are usually not cooked before consumption, providing a richer source of dietary microorganisms.
study conducted a test on the microbial content in fermented muscle tissue. It was found that these foods contain a very unique microbiome. Most of the bacteria found on walrus and seal meat are clostridium bacteria, and narwhals contain high levels of clostridium bacteria and Bacteroides .
Long-term intake of live microorganisms and some fermented foods, is very important for intestinal health.
The key skinny dragon says
Regarding the relationship between dietary fiber and constipation, we have shared a very special study before.
Do not eat or reduce dietary fiber, constipation problems are more likely to disappear, which is exactly the opposite of modern intestinal nutrition .
The low-fiber diet of Inuit people, compared with high fiber, the intestinal diversity may not be that complicated, but the intestine is very healthy and there is no problem with constipation.
But unfortunately, like many other indigenous people in the world, Inuit is also rapidly moving from traditional diets to more modern diets.
Many problems are beginning to increase, and chronic diseases are also beginning to develop.
