Protein & Alzheimer's [6:43] Laurel says: Hi Robb, How are you? I hope you and Nikkie are doing well.  I just recently have entered the world of Alzheimer's via my cousin who is in her 60s. It is unbelievable to not 'find' my real cousin in there anymore - she is literally vacant, with tiny glimmers of her former self popping up randomly and then being instantly gone. I will soon be helping the family take care of her in some way. I started to google Alzheimer's research and found this. With so many turning carnivore, and me potentially wanting to toy with my cousins diet to try to help, can I do harm by encouraging more protein consumption? What do you think? https://www.sciencedaily.com/releases/2020/01/200122080532.htm Alzheimer's Disease affects millions More than 5.7 million Americans have Alzheimer's disease, which is the primary cause of dementia and sixth-leading cause of death in the United States. That population is predicted to reach 14 million by the year 2050, according to the Alzheimer's Association. The relationship between Alzheimer's (and subsequent brain atrophy) and amyloid plaques -- the hard accumulations of beta amyloid proteins that clump together between the nerve cells (neurons) in the brains of Alzheimer's patients -- has been well-established among researchers. Less understood is precisely how that amyloid-beta actually leads to plaque formation -- and where this new work appears to have broken new ground, Wang said. Further, while there has been much research into what genes might influence whether or not someone gets Alzheimer's, there is less understanding of genes that might be linked to the progression of the disease, meaning the formation of plaque and subsequent atrophy in the brain. The role of 'aggregatin' protein In the new work, the researchers began by correlating roughly a million genetic markers (called single-nucleotide polymorphisms, or SNPs) with brain images. They were able to identify a specific SNP in the FAM222, a gene linked to different patterns of regional brain atrophy. Further experiments then suggested that the protein encoded by gene FAM222A is not only associated with AD patient-related beta-amyloid plaques and regional brain atrophy, but that "aggregatin" attaches to amyloid beta peptide -- the major component of plaque and facilitates the plaque formation. So when researchers injected mouse models with the "aggregatin" protein (made from the FAM222A gene), plaque (amyloid deposits) formation accelerated in the brain, resulting in more neuroinflammation and cognitive dysfunction. This happened, they report, because the protein was found to bind directly the amyloid beta peptide, thus facilitating the aggregation and placque formation, Wang said. Conversely, when they suppressed the protein, the plaques were reduced and neuroinflammation and cognitive impairment alleviated. Their findings indicate that reducing levels of this protein and inhibition of its interaction with amyloid beta peptide could potentially be therapeutic -- not necessarily to prevent Alzheimer's but to slow its progression. Thanks Robb, I await your take on this. Best, Laurel Here is a neat map. Don't know how they get their numbers though. https://www.worldlifeexpectancy.com/cause-of-death/alzheimers-dementia/by-country/ and here is the last one from me today... you likely have already read all this stuff. Poland has a low Alzheimer's death rate, and this study seems to have Polish origins.https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6356942/ 2. Question Regarding Vegetarians [16:46] Karoliina
