| Ēd desiņu un iegūsti kognitīvo spēju zudumu un demenci. |

People who eat more red meat, especially processed red meat like bacon, sausage and bologna, are more likely to have a higher risk of cognitive decline and dementia when compared to those who eat very little red meat, according to a new study of 133,771 people followed up to 43 years.
Higher intake of red meat, particularly processed red meat, was associated with a higher risk of developing dementia and worse cognition. Reducing red meat consumption could be included in dietary guidelines to promote cognitive health. Further research is needed to assess the generalizability of these findings to populations with diverse ethnic backgrounds.

| Omnivore, vegan and vegetarian diet quality associations with depressive symptoms. |
[Jan. 9th, 2025|06:36 pm] |
A nine-year study of about 10,000 women found no significant link between diet type (plant-based or omnivore) and depressive symptoms. However, diet quality (fresh versus processed foods) had a correlation, with higher-quality diets reducing depressive symptoms.

Animal sentience is often thought of as a complex, poorly defined, subjective, and abstract concept, raising as many questions as it does answers. If you talk to different people about their views on animal sentience you will undoubtedly get various responses. If you asked a pet owner whether animals have feelings, they would regale you with stories of when their dog comforts them, or is proud of himself when he opens a closed door. A farmer who works closely with his or her animals may tell you about how cow number 19 likes being tickled behind her ears, and how cow number 25 is the shy and cautious one. But then you may talk to someone who sees animals only in terms of their monetary value. Animals to such people are not living, sentient beings, they represent commodities. It is far easier for them to see animals in this way but far less convenient for them to consider their ability to suffer or their need to experience positive emotions like pleasure. How people perceive animals is never black and white, attitudes may depend on the species in question, and the animals perceived mental ability [47]. However, when you consider how we treat the animals we farm for food, experiment upon, or use for entertainment, you can clearly see how important these perspectives are, and which the dominant ones are.

| Par D vitamīnu. |
[Nov. 8th, 2024|08:21 pm] |
Aizmaldījos pa internetiem līdz podkāstam par D vitamīnu. 2 Doktori apgalvo, ka D vitamīna, kurš nemaz nav vitamīns, jo mēs paši labi varam to saražot, iedod tikai nedaudz saules gaismas, avitaminoze ir reti sastopama un D vitamīna lietošana nav zinātniski pamatota, bet industrijas izdomājums. Video komentos attiecīgi doktori tika nolikti, ka runājot muļķības.
Tas man lika pameklēt pētījumus par tēmu. Neatradu pārliecinošus datus par D vitamīna lietošanas vajadzību. D vitamīns esot vispārējās veselības rādītājs, kura līmenis katram indivīdam atšķiras. D vitamīna avitaminozei ir konkrēti sāpīgi simptomi. Prikolīgi, bet būtu labāk videospēles spēlējis, nevis galvu jaucis. |

| The Impact Plant-Based Diets Have on Athletic Performance and Body Composition: A Systematic Review |
[Jun. 29th, 2024|06:42 pm] |
Patīkami, kad personīgā anekdote sakrīt ar objektīvo realitāti.
Following a plant-based diet does not harm athletic performance.
Plant-based diets may improve maximal oxygen consumption, vertical countermovement jumps, and relative strength.
There is no evidence that plant-based diets are detrimental to athletic performance or body composition.
The long-term implications and the affect following a plant-based diet has on athletic performance in professional athletes are still unknown.

Introduction: Tryptophan is catabolized by gut microorganisms resulting in a wide range of metabolites implicated in both beneficial and adverse host effects. How gut microbial tryptophan metabolism is directed towards indole, associated with chronic kidney disease, or towards protective indolelactic acid (ILA) and indolepropionic acid (IPA) is unclear.
Methods: Here we used in vitro culturing and animal experiments to assess gut microbial competition for tryptophan and the resulting metabolites in a controlled three-species defined community and in complex undefined human faecal communities.
Results: The generation of specific tryptophan-derived metabolites was not predominantly determined by the abundance of tryptophan-metabolizing bacteria, but rather by substrate-dependent regulation of specific metabolic pathways. Indole-producing Escherichia coli and ILA- and IPA-producing Clostridium sporogenes competed for tryptophan within the three-species community in vitro and in vivo. Importantly, fibre-degrading Bacteroides thetaiotaomicron affected this competition by cross-feeding monosaccharides to E. coli. This inhibited indole production through catabolite repression, thus making more tryptophan available to C. sporogenes, resulting in increased ILA and IPA production. The fibre-dependent reduction in indole was confirmed using human faecal cultures and faecal-microbiota-transplanted gnotobiotic mice.
Conclusion: Our findings explain why consumption of fermentable fibres suppresses indole production but promotes the generation of other tryptophan metabolites associated with health benefits.
