Research increasingly demonstrates that healthy nutrition improves mental health, and an entirely new subspecialty has formed to support this. Nutritional psychiatry is expanding rapidly, with research growing 15-fold from 2000 to 2024, reflecting the increasing acceptance of diet's role in mental health.
The article from the journal argues that the gut-autism axis is a house of cards built on lousy studies with inconsistent data. They assert that the studies are contradictory and that too much emphasis is placed on dubious mouse models. It is notoriously challenging to nail down microbial causes of disease—it is hard enough to simply identify a normal microbiome.
There are some communities that are very unhealthy where the diversity is higher. Low diversity is not a universal marker. We found something that at first seemed surprising. That a healthy microbiome has lots of competition. These bugs are all going after the same food. In an unhealthy gut, on the other hand, you see tight cooperation - microorganisms are helping each other out.
Gut bacteria are crucial to ensuring healthy digestion and defecation. But two species of bacteria may also be the cause of constipation: according to a new study, Bacteroides thetaiotaomicron and Akkermansia muciniphila appear to work in concert to break down colonic mucin, the slimy coating in our colons that keeps our poo moving along. Too little mucin means a drier and more constipation-prone colon.
Although specific bacterial taxa have been associated with favourable clinical responses to immune checkpoint blockade (ICB) in cancer patients12,13,18,19,20,21,22, the mechanisms by which the intestinal microbiota influences anti-tumour immune responses remain poorly defined. Products of the microbiota, including metabolites23,24,25 and innate receptor ligands26, may reprogramme myeloid cells27, lowering the activation threshold for antigen presentation and thereby facilitating priming and activation of tumour-reactive T cells.
Everything on my Instagram feed at the moment is about worms and parasites, she told the Wall Street Journal, ominously adding: I don't know what the heck is going to come out. Maybe your social media feeds aren't full of posts about worms and parasites, in which case, congratulations. But type parasite cleanse into TikTok or Instagram and you'll be inundated with so-called experts peddling expensive herbal supplements that promise to detox the body and rid it of harmful worms and parasites.
Being overweight doesn't just make people more susceptible to chronic illnesses such as heart disease and diabetesit might also increase their risk of severe influenza and other infections, a new study confirms. The study, published today in the Lancet, suggests that people with obesity may be more susceptible to death and hospitalization from a variety of infections caused by viruses, fungi, parasites and bacteria.
Intermittent fasting within an eight-hour window can significantly reduce symptoms of Crohn's disease, a new study has found. Crohn's disease, according to the NHS, is a long-term condition where part of the gut becomes inflamed. It cannot currently be cured and the common symptoms include: diarrhoea, blood or mucus in your poo and stomach pain. Researchers at the University of Calgary found that time-restricted feeding can reduce disease activity by 40 per cent and halve abdominal discomfort in over 12 weeks in people living with Crohn's disease.
During viral infection and in the case of cancer, CD4+ helper T-cells release cytokines, or small signaling proteins, that activate and "give permission" to other immune cells to control and clear viral pathogens. In certain viral infections, such as lymphocytic choriomeningitis virus (LCMV), which is spread by infected rodents, CD4+ T-cells differentiate into different subpopulations, including one subset of progenitor CD4+ T-cells that replenish type 1 helper (Th1) and follicular helper (Tfh) T-cells.
