Mediterranean Diet for Longevity
Posted in food, life extension
I could find hardly any scientific studies that showed negative results from the Mediterranean Diet for longevity, which honestly makes me a little wary of scientific establishment groupthink.
That said, I think I am going to start taking shots of olive oil after all my research…
Is the Mediterranean Diet the key to longevity? Lots of research suggests olive oil and other Mediterranean foods can help you live longer.

It might not look like much, but this little worm could hold the key to biological regeneration!
Researchers have made an extraordinary discovery using a creature in common to the Gulf of Eilat. The creature is called Polycarpa mytiligera and is a species of ascidian, which is a marine animal commonly found in the waters of the Gulf that is capable of regenerating its organs. Surprisingly, the researchers discovered the animal can regenerate all of its organs even when dissected into three fragments.
Scientists say that is an astounding discovery because it’s an animal belonging to the Phylum Chordata, which are animals with a dorsal cord, which also includes humans. The ability to regenerate organs itself is not uncommon in the animal kingdom. One example is the gecko able to regrow its tail. However, it’s not common for creatures to be able to regrow entire body systems.
With the Polycarpa mytiligera, scientists have discovered a creature able to regenerate all organs even if separated into three pieces, each piece knowing exactly how to regain the function of all of its missing body systems within a short period. Project researcher Tal Gordon says that by all accounts, the ascidian is a simple organism with two openings in its body, and inside the body is a central organ resembling a pasta strainer.
To answer this question, an internal team of scientists, consisting of researchers affiliated with the Buck Institute for Research on Ageing, and researchers from Nanjing University decided to modify both the Insulin and the rapamycin pathways of a group of C.elegans worms, expecting to see a cumulative result of a 130% increase in lifespan. However, instead of seeing a cumulative effect in lifespan, the worms lived five times longer than they normally would.
“The synergistic extension is really wild. The effect isn’t one plus one equals two, it’s one plus one equals five. Our findings demonstrate that nothing in nature exists in a vacuum; in order to develop the most effective anti-aging treatments we have to look at longevity networks rather than individual pathways.” – Jarad Rollins of Nanjing University.
What could this mean for human regenerative medicine? Humans are not worms, however on a cellular level they do possess very similar biology. Both the insulin pathway and the rapamycin pathway are what is known as ‘conserved’ between humans and C.elegans, meaning that these pathways have been maintained in both organisms. In the distant past, both humans and C.elegans had a common ancestor, in exactly the same way as humans and Chimpanzees have a common ancestor. Evolution has changed our bodies significantly over the millions of years that humans and C.elegans have diverged from one another, but a lot of our fundamental biological functions remain largely unchanged.
**Low birth weight tied to accelerated aging in boys**
A study in Pediatrics found that boys who weigh less than 2 pounds at birth aged faster and were five years older biologically in their early 30s, compared with boys who were born at the same time but whose birth weights were normal. The findings were based on the genes of 45 individuals who were extremely low birth weight and those of 47 whose birth weights were normal.
MONDAY, May 17, 2021 (HealthDay News) — Boys who weigh less than 2 pounds at birth don’t age as well as their normal-weight peers, a long-term study finds.
Canadian researchers have followed a group of extremely low birth weight (ELBW) babies and their normal-weight counterparts since 1977.
When participants were in their early 30s, researchers compared the genes of 45 who were ELBW babies with those of 47 whose birth weight was normal.
The secret to longevity is already in the animals around us.
Some species live unexpectedly long lives. By studying how they do it, researchers hope to pinpoint factors affecting human longevity.

Life, for most of us, ends far too soon — hence the effort by biomedical researchers to find ways to delay the aging process and extend our stay on Earth. But there’s a paradox at the heart of the science of aging: The vast majority of research focuses on fruit flies, nematode worms and laboratory mice, because they’re easy to work with and lots of genetic tools are available. And yet, a major reason that geneticists chose these species in the first place is because they have short lifespans. In effect, we’ve been learning about longevity from organisms that are the least successful at the game.

In our ongoing search to continuously improve our health, we occasionally pay lip service to the bacteria that live inside our gut. Normally this concern rarely manifests as anything more than occasionally remembering to buy some of those small bottles of pro-biotic yoghurts while shopping for your…
Recent discoveries have led to the conclusion that the gut plays an important role in cognitive function, with a large amount of research into understanding what is known as the gut-brain axis, which is the collective name given to the biochemical signalling pathways which take place between the gastrointestinal tract and the central nervous system. With an ever-increasing understanding of this pathway, along with an expanded understand of the gut flora (which was found to decline with age), researchers started to ask how the gut flora are involved in the ageing process.
In order to test how exactly ageing gut flora effects the gut-brain axis, researchers at the University of East Anglia conducted a faecal transplant from elderly mice into younger mice. Following this transplant, the young mice were then put through a serious of tests to assess their cognitive abilities. The younger mice showed significant changes in their microbial profiles, as well as significantly impaired capacity for spatial learning, as well as a decreased capacity for memorisation. These mice also showed an altered expression of proteins associated with neurotransmission and neuroplasticity, along with changes in the mice’s hippocampus, which is responsible for allowing the mice to memories new information, as well as recalling previous memories.
This research has successfully proven a link between the changing microbiome of the gut and protein expression within the central nervous system. This discovery is exceptionally good news, as not only is the problem potentially fairly easy to fix (with an aforementioned faecal transplant), but it also provides clues as to how we might compensate for this age related change in the gut microbiome with medication tailors to mimic the role of a young microbiome. Either way, the discovery has opened the door to a number of exciting prospects for regenerative medicine, along with maybe highlighting the fact that we should really start considering our gut bacteria as more than just a collection of microorganisms, and more of a collection of symbiotic organisms that benefit us in ways that we are only just beginning to understand.
To begin with, why do we use mice in medical and biological research? The answer to this question is fairly straight forward. Mice are cheap, they grow quickly, and the public rarely object to experimentations involving mice. However, mice offer something that is far more important than simple pragmatism, as despite being significantly smaller and externally dissimilar to humans, our two species share an awful lot of similarities. Almost every gene found within mice share functions with genes found within humans, with many genes being essentially identical (with the obvious exception of genetic variation found within all species). This means that anatomically mice are remarkably similar to humans.
Now, this is where for the sake of clarity it would be best to break down biomedical research into two categories. Physiological research and pharmaceutical research, as the success of the mouse model should probably be judges separately depending upon the research that is being carried out. Separating the question of the usefulness of the mouse model down into these two categories also solves the function of more accurately focusing the ire of its critics.
The usefulness of the mouse model in the field of physiological research is largely unquestioned at this point. We have quite literally filled entire textbooks with the information we have gained from studying mice, especially in the field of genetics and pathology. The similarities between humans and mice are so prevalent that it is in fact possible to create functioning human/mouse hybrids, known as ‘genetically engineered mouse models’ or ‘GEMMs’. Essentially, GEMMs are mice that have had the mouse version of a particular gene replaced with its human equivalent. This is an exceptionally powerful tool for medical research, and has led to numerous medical breakthroughs, including most notably our current treatment of acute promyelocytic leukaemia (APL), which was created using GEMMs.
