Did they fund the study? It sounds like they were simply promoting, writing about it? Here are authors, they don't seem affiliated with the OP's "Plant based news" article. Can't really fault an organization from promoting a study that aligns with them.

The article found at the URL submitted by OP ( https://plantbasednews.org/news/science/fermented-foods-huma... ) seems like classic blogspam, i.e. regurgitation, of this Harvard Gazette article: https://news.harvard.edu/gazette/story/2024/02/did-fermented... IMHO HN staff should, as the often do in such cases, update the OP link to point to the Harvard Gazette article. As for the questioned passage, it appears to ori…

At least for me, I was responding to those that wanted to call the study biased, or invalidate, or question the results, because the original post was 'classic blogspam'.

The study was in Nature, not 'plantbasednews'.

Just because a blog with a bias, like 'plantbasednews', reports on a study, doesn't invalidate the study.

The 'blog' is just cherry picking the studies that align with their bias.

Nature causes various food sources to ferment which is exploited by many animals.

Like what? Usually lacto fermenting requires a specific salt level. I know fruit tends to ferment, but that produces alcohol, which is a negative factor for brains.

human pathogens can't live in alcohol. so a low alcohol liquid would be sterile and healthy for humans.

brain health isn't the big factor, it is outweighed by the not heaving out your guts by food poisoning.

Lacto only requires a specific salt level to keep the bad bacteria out. I doubt caveman humans cared much about sanitary conditions. Also, I doubt the vessels they used would be air tight (except to expel gases) like the ones I use. Modern humans have genes to process alcohol and some populations don’t have the gene (Asian flushing). Alcohol and fermented fruit were probably sources of calories and drinkable water fo…

"Alcohol and fermented fruit were probably sources of calories and drinkable water for many populations."

I'm questioning how this could have preceeded the formation of advanced brains at a level to contribute to the formation of advanced brains.

This isn't true at all. Beer can go bad and give you food poisoning.

No. As you obviously know by the phrasing of your question, the issue is that the vegan community has a particular history of agenda over science, and the concern is that any group that starts with a conclusion will build research to support their agenda rather than create objective evidence.

Agenda over science? What? It isn’t anti-science to be against eating meat because of its role in climate change. To think otherwise would be anti-science.

> Agenda over science?

The person you are responding to is right. The anti-meat/ pro-plant position may not have direct industry ties, but the bias is evident in several ways, of which I'll present just a few:

> But what has for the most part been overlooked is that Katz and THI and many of its council members have numerous industry ties themselves. The difference is that their ties are primarily with companies and organizations that stand to profit if people eat less red meat and a more plant-based diet. Unlike the beef industry, these entities are surrounded by an aura of health and wellness, although that isn’t necessarily evidence-based.

- Dr. David M Klurfeld] was on the World Health Organization working group to decide if meat causes cancer in 2015 with a bunch of vegetarians and vegans and says it was the most frustrating professional experience of his life - There were 22 scientists - half of which were epidemiologists - They claimed they used 800 studies but they actually only used 18 - There was a group of people that were strongly against the vote - He thinks a number of the people made up their minds before they even arrived

> Looking back I think there were many factors that shaped my previously held stance on nutrition. I believe my education set me up to be susceptible to a plant-based diet. I was educated that too much red meat is not good. I was educated to value fruits and vegetables over meat. With this mind set, I was predisposed into believing red meat was bad for me and that the only animal protein (if any) I should eat was chicken and fish. I became further disgusted by red meat through documentaries and books with a vegan agenda. Red meat causes climate change, red meat decreases our life expectancy, red meat is morally bad. This pushed me further away from red meat and meat in general. I became more focused on this ideology of health rather than listening to my own body. Without me even realizing it, I began to shape my identity around a plant-based diet. It was really hard for me to break up with this idea of what I thought was healthy and it took me months of self-education to open up my eyes.

> The emphasis on health ministry within the Seventh-day Adventist (SDA) movement led to the development of sanitariums in mid-nineteenth century America. These facilities, the most notable being in Battle Creek, Michigan, initiated the development of vegetarian foods, such as breakfast cereals and analogue meats. The SDA Church still operates a handful of food production facilities around the world. The first Battle Creek Sanitarium dietitian was co-founder of the American Dietetics Association which ultimately advocated a vegetarian diet. The SDA Church established hundreds of hospitals, colleges, and secondary schools and tens of thousands of churches around the world, all promoting a vegetarian diet. As part of the ‘health message,’ diet continues to be an important aspect of the church’s evangelistic efforts. In addition to promoting a vegetarian diet and abstinence from alcohol, the SDA church has also invested resources in demonstrating the health benefits of these practices through research. Much of that research has been conducted at Loma Linda University in southern California, where there have been three prospective cohort studies conducted over 50 years. The present study, Adventist Health Study-2, enrolled 96,194 Adventists throughout North America in 2003–2004 with funding from the National Institutes of Health. Adventist Health Studies have demonstrated that a vegetarian diet is associated with longer life and better health.

> Dietary policies, mass media, and activists increasingly portray plants as mostly beneficial and animal source foods (ASFs) as mostly harmful. Yet, both sides of this poorly informative plant/animal binary represent heterogeneous food groups, which can be either benign or harmful from an ethical, environmental, or health perspective. It is not helpful to base policies on such simplistic categorization, which derives from reductionist approaches to nutrition, distortions by journalists, societal anxieties, and various forms of bias.

Actually the big evolutionary advantage of humans is that they can thrive on a wide range different diets. Unlike other animals we can almost eat everything.

There's large parts of the food world that are completely inaccessible to humans. Most plant material (i.e. "fiber", digestible by e.g. cows), carion, most raw meat (if we ate what dogs ate, we'd have constant stomach issues...)

>carion, most raw meat (if we ate what dogs ate, we'd have constant stomach issues...)

Humans have extremely acidic stomach acid (1.5 - 3.5 pH), close to that of vultures and dogs (1 - 2 pH).

Early humans and their predecessors, were very likely (at least partially) carrion feeders, and consumed raw meat for millions of years before they started cooking.

I keep hearing about this "dead" yogurt. What does this mean?

It refers to whether the yogurt is alive or dead. It's not exactly mysterious terminology. You get yogurt by using bacteria to process milk. In order to do their processing, the bacteria need to be alive. So, for example, adding living yogurt to milk will get you more yogurt, but adding dead yogurt to milk will get you milk with some dead yogurt in it.

I agree it's not mysterious. I was asking with some admittedly false naivety because if I'm being honest, I'm skeptical. I've only ever heard about this from people whose opinions on nutrition are dubious in other ways, and it's usually phrased as something like "all the yogurt you get from the store is dead." I eat yogurt every day and I sometimes make my own (using commercial yogurt as a starter), and I've never had a batch fail to start. Apparently I've only ever bought the live stuff.

my take based on several such articles. 8-10M ago humans (big apes that we were back then) got the ability to metabolize alcohol, ie. all those plentiful of fermenting/rotting fruit on the ground became food. That in particular allowed for less tree climbing, more walking on the floor. That, in particular for the purposes of self-defense and body calories storage - to more body mass - that in turn to less tree climbi…

Very interesting theory. Do we know what types of fruits they would have been eating off the ground? Also wondering if alcohol metabolization can be traced in dna or similar to align this theory.

yes, it is DNA tracing, for example (and note - "increasing terrestrialization"):

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8308604/

"Paleogenetic reconstruction of alcohol dehydrogenase genes across the hominid phylogeny indicates a dramatically enhanced catabolic capacity in one particular ADH (ADH4, as encoded by the ADH7 allele), starting at about 10 Mya [26]. ADH4, although only one of multiple ADH forms present in mammals, is found primarily in the mouth and digestive tract and thus effects the “first pass” at the digestion of ethanol. This enzyme became dramatically better at metabolizing ethanol following the phyletic split between the lineage leading to modern orangutans and to the other great apes, including ourselves. It thus correlates well with increasing terrestrialization among the African apes, possibly yielding greater access to fermenting fruit crops on the ground, and thus resulting in increased ethanol within the diet [26]. "

Sure you can, but the thing about ideologies is that they are almost always pseudo-religious philosophies, and those entities that make them their foremost identity typically seek out supporting facts while ignoring contravening facts. Expecting this behavior is reasonable, almost all ideologues engage in it to some degree. Thus additional skepticism/verification is warranted when the source is an ideologue and the p…

It was an article in 'plantbasednews', about a totally separately funded study that had a positive result for 'plants'. This is a site to report 'plant based news', reporting on a study about 'plants'. The site does not label itself as : "Completely un-biased news site weighing the thousands of studies dealing with all food types and providing equal 50-50 coverage of both plants and meat studies so people on the inte…

When "plant-based" is used as a euphemism for "vegan," I find that annoying and borderline dishonest.

We all eat plants. Even lots of plants. But most of us are not vegan.

So if these people are vegan and pushing a vegan agenda ... I wish they'd make it more clear than "plant based."

Incidentally, kimchi is easy to make, delicious, and healthy. AND most kimchi recipes are not vegan - they include one or two fishy ingredients.
