Another study points to the connections between our gut health and what we eat.

An April 15 2021 Genetic Engineering and Biotechnology News reported that high dietary intake of animal products, processed foods, alcohol and sugar could lead to inflammation in our gut, according to a study by the University of Groningen and University Medical Centre Groningen. This diet showed to support the abundance of inflammatory Firmicutes and Ruminococcus sp in our gut.

A diet rich in plant-based foods was found to promote the opposite affect. For example, nuts, oily fish, fruit, vegetables was linked to a higher abundance of healthy bacteria such as Faecalibacterium sp.

University of Groningen's Laura A. Bolte, PhD, and colleagues, studied 1425 individuals many of whom suffered from some type of gut related disease and compared their diets to a control group of 871 gut healthy individuals.

The SciTech Daily reported on April 12 2021 new metabolic capabilities of gut bacteria, according to a study by University of Vienna and Professor David Schleheck from the University of Konstanz. For the first time, the researchers found that our gut microbes digest plant-based, sulfur-containing sugar sulfoquinovose, which exist in many green vegetables such as spinach and algae. They found that low concentrations of hydrogen sulfide in the gut can have anti-inflammatory effects, while excessive amounts may be connected to diseases such as cancer.

An earlier study by microbiologist David Schleheck at the University of Konstanz discovered that other microorganisms can use the sulfosugar as a nutrient. Now, they have confirmed that the gut microbiome in humans contribute to how nutrition affects our health.

The new study found that "sulfoquinovose stimulates the growth of very specific key organisms in the gut microbiome,” says David Schleheck quoted in SciTech Daily, including Eubacterium rectale which is associated with healthy people. On the other hand, high concentrations were associated with chronic inflammatory diseases.

Quoted in the Harvard Gazette March 23 2021, “Evidence in humans and many animals to this point suggests that, surprisingly, genetics plays a small role compared to environmental influences,” according to Rachel Carmody, an assistant professor in the Department of Human Evolutionary Biology and principal investigator of the department’s Nutritional and Microbial Ecology Lab.

Her team studied a number of different animals that were domesticated and given "foods originally cultivated for human use, in processed forms that are relatively easily digestible," Carmody is quoted as saying in the Harvard Gazette article. The result is they found that the microbiomes of these different species, from dogs to pigs to rabbits, became commonly similar. Carmody’s lab previously studied how the gut biome squad of both mice and humans changed, and changed quickly, simply through diet changes. The end result suggests that genetics plays a limited role in gut microbiome make up.

Your ability to resist pathogens largely depends on your gut microbiome

Recent studies have shown that gut microbiota can build resistance to gut colonization by disease-causing microorganisms (pathogens). Conversely, prolonged and/or high levels of antibiotic use in people promotes expansion of Clostridium difficile, a bacterium that causes severe diarrhoea and inflammation of the colon.

Scientists again have found that when one becomes infected with a pathogen changes occur in the microbial community that enhances one's ability to combat the harmful bacteria. The strength of one's resistance varies from person to person, according to Apollo Stacey of the National Institute of Health laboratory of Host Immunity.

It has been known that antibiotic use in people promotes expansion of Clostridium difficile, a bacterium that causes severe diarrhoea and inflammation of the colon, leading to a high risk of disease and death. Likewise, Salmonella enterica and C. rodentium respond to microbiota in the gut to strength or weaken their virulence. Stacey's team found that a naturally produced chemical in the body called taurine nourishes and trains the microbiota to promote its resistance to subsequent infection.

Researchers from the U.S. and India on the International Space Station discovered previously unknown microbes, according to a a March 16 2021 article in Science Alert.

They found four strains of bacteria living in different places in the ISS, including Methylorubrum rhodesianum and the previously unknown species which were named IF7SW-B2T, IIF1SW-B5, and IIF4SW-B5, according to Science Alert. This family of bacteria found in soil and freshwater are involved in nitrogen fixation, plant growth, and can help stop plant pathogens, says team lead University of Southern California geneticist Swati Bijlani.

Natalia Shulzhenko, an associate professor of biomedical sciences at the Oregon State University (OSU) and her associates have employed a data-driven, systems-biology approach called Transkingdom network analysis to study host-microbe interactions under a western diet, according to a January 05 2021 report by News 18 television station in Noida, Uttar Pradesh, India. They use operational taxonomic units, or OTUs to categorize bacteria based on gene sequence similarity, says the report.

The OSU team studied Lactobacillus Johnsonii, Lactobacillus Gasseri, Romboutsia Ilealis and Ruminococcus Gnavus, for example, and their impact on the western diet. The team compared multiple studies of both humans and mice and the abundance of these four bacteria on our body mass index (BMI). With this analysis, R. Ilealis to be present in more than 80 per cent of obese patients, according to the News 18 report.

According to a recent February 26 2021 article in Mind Body Green, akkermansia municiphila is the great gut protector, supplying our gut lining with a protective layer of mucus. A common gut ailment called leaky gut is connected to a deficiency of Akkermansia.

The weakening of our gut wall can enable undigested food particles and bacteria to "leak" into the bloodstream which causes inflammation, even worse, gastrointestinal diseases, according to Dr. Mark Hyman, founder and director of The UltraWellness Center, the Head of Strategy and Innovation of the Cleveland Clinic Center for Functional Medicine who is quoted in the article.

There are a number of foods that are high in anti-oxidant properties such as pomegranate, green tea, and cranberry. These phytochemicals contain large amounts of tannins, flavonols, anthocyanins which feed the akkermansia bacteria.

In the article, Dr. Hyman also mentions the importance of Akkermansia for certain drug cancer treatments which are only effective with the presence of this bacteria in the gut.

According to a February 19 2021 article in Genetic Engineering and Biotechnology News (Genengnews) researchers have built "the Gut Phage Database" (GPD), a collection of 142,000 nonredundant viral genomes (>10 kb) obtained by mining a dataset of 28,060 globally distributed human gut metagenomes and 2,898 reference genomes of cultured gut bacteria.” They identified common ancestors among the identified viruses.

Researchers at Wellcome Sanger Institute and EMBL’s European Bioinformatics Institute (EMBL-EBI) claim that more than half of these viruses have never been seen before.

Genengnews quoted Alexandre Almeida, PhD, postdoctoral fellow at EMBL-EBI and the Wellcome Sanger Institute saying this could lead to new treatments such as antimicrobials from bacteriophage origin.

Evidence microbes connect Nature's health to human health; 経験的証拠では自然の健康を人間の健康に結びつけます

Microbes out in Nature, from cyanobacteria to diatoms, could affect human health, according to a January 16 2021 report in Phys.Org by Kevin Dillon, a doctoral student in the lab of co-author Professor Donna E. Fennell, chair of the Rutgers University-New Brunswick, Dept. of Environmental Sciences, Environmental and Biological Sciences. They found these microbes travel in clouds distributing themselves throughout nature, including soil, rivers, and lakes (1).

It has been known that phytoplankton such as diatoms and various forms of algae thrive in nutrient-rich coastal waters, during oceanic spring blooms, and fresh water environments. The algae include blue-green (cyanobacteria), green, red and golden algae, and diatoms (another form of algae).

The power of microbes is their ability to recycle the primary elements of all living systems, such as carbon, nitrogen, and oxygen. Plankton are responsible for much of the food we eat and the air we breathe (2). Dillon says their research can lead to unlocking specific genes associated with the production of toxins by these microorganisms and limiting their growth. What this means is our well being really does go full circle in the "circle of life", and the connection is more interdependent than we may have ever suspected.

In addition to our personal health, diatoms hold 20% of carbon emissions in check, playing a major role in climate change control and is a major source of food for mammals such as whales, according to the American Association for the Advancement of Science (3). Additional research by the Norwegian University of Science and Technology say these tiny plankton drive a process called the "biological pump", consuming carbon dioxide from the atmosphere and moving it to sediments in the deep ocean (4).

経験的証拠では自然の健康を人間の健康に結びつけます

2021年1月16日にPhys.Orgで報告されているように共著者、ラトガース大学環境科学、環境生物科学科の議長のDonna E.Fennell教授の研究室の博士課程の学生であるKevin Dillonによると、シアノバクテリアや珪藻など自然界に存在する微生物は、人間の健康に影響を与える可能性があります。この微生物が雲の中を移動し、土壌、川、湖などの自然全体に分布していることを発見されました。

珪藻やさまざまな藻類などの植物プランクトンは、栄養豊富な沿岸水域で、海洋性の春咲きの時、或いは淡水環境で繁殖することが知られています。藻類には、青緑色（シアノバクテリア）、緑・赤・黄金色藻、珪藻（別の形態の藻）が含まれます。

微生物の力は、炭素、窒素、酸素など、すべての生命システムの主要な要素をリサイクルする能力です。プランクトンは私たちが食べる食品と呼吸する空気の多くに役割を果たす。アメリカ科学振興協会によると、珪藻は私たちの個人的な健康に加えて、炭素排出量の20％を抑制し、気候変動の制御に大きな役割を果たし、クジラなどの哺乳類の主要な食料源となっています。

ノルウェー科学技術大学の研究によると、この小さなプランクトンは「生物ポンプ」と呼ばれるプロセスを駆動し、大気から二酸化炭素を消費して深海の堆積物に移動させます。
