How our microbiome is shaped by family, friends and even neighbors

People living in same household or in regular contact tend to have same microbes in their guts & mouths. The study raises possibility that diseases linked to #microbiome dysfunction, including #cancer, #diabetes & #obesity, could be partly transmissible. People living in the same household share more than just a roof (and pints of milk). Be they family or flatmate, housemates tend to have the same microbes colonizing their bodies, and the longer the cohabitation, the more sim

Fighting obesity in San Joaquin County, California

While popular fast-food chains such as Raising Cane’s and In-N-Out continue to open locations and thrive on hungry stomachs in the North San Joaquin County district, the combined #overweight and #obesity rate has climbed to greater than 65% of the local population, a historic high. By emphasizing certain priority communities and engaging with the community to address socioeconomic and ethnic disparities which are at the root of the obesity epidemic, it is not too late to reve

Food allergy is associated with lower risk of SARS-CoV-2 infection

A study found that people with food #allergies are less likely to become infected with the #SARSCoV2 #coronavirus. The study also found that #obesity & high body mass index (BMI) are associated with increased risk of infection, while having asthma does not increase risk.

Inflammasome activation at the crux of severe COVID-19

Review of evidence that #SARSCoV2#coronavirus directly or indirectly activates #inflammasomes, leading to secretion of IL-1 family cytokines (IL-1beta and IL-18), and pyroptosis, an inflammatory form of cell death. The #COVID19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), results in life-threatening disease in a minority of patients, especially elderly people and those with co-morbidities such as #obesity and #diabetes. Severe disease is c

This mushroom might alter gut bacteria for the better, study finds

A mushroom a day may keep the doctor away. The active ingredients in a Asian mushroom used in traditional Chinese medicine (#TCM) can change bacteria in your stomach for the better, researchers have found. By altering gut bacteria, the #Reishi mushroom (#Ganoderma lucidum, #lingzhi #靈芝) prevents and reverses symptoms of #obesity in mice, including weight gain and insulin resistance. “Mice kept on a high-fat diet gained up to 25 percent more than mice kept on the same diet wit

The obesity fighting mushroom: Chinese medicine counters diabetes and weight gain

#Reishi #microbiota #lingzhi #obesity #insulin #microbiome #Ganoderma #mushrooms #diet #nutrition As any gardener knows, plants need the right mix of fertilisers to flourish – and the same seems to be true for your gut bacteria. Microbiologist David Ojcius from Taiwan’s Chang Gung University and his colleagues found the secret to a healthy gut is what you feed them – and that perfect meal could come from a humble mushroom. They published their findings in Nature Communication

Association between periodontal pathogens and systemic disease

#oralhealth #inflammation #Alzheimers #pregnancy #pneumonia #obesity #diabetes #heartidisease A growing body of literature suggests that there is a link between periodontitis and systemic diseases. These diseases include cardiovascular disease, gastrointestinal and colorectal cancer, diabetes and insulin resistance, and Alzheimer's disease, as well as respiratory tract infection and adverse pregnancy outcomes. The presence of periodontal pathogens and their metabolic by-produ

Genetic admixture in the South Pacific: From Denisovans to the human immune response

#immunology #evolution Scientists have looked at understudied human populations from the South Pacific, which are severely affected by a variety of diseases, including vector-borne infectious diseases such as #Zika virus, #dengue, and #chikungunya, and metabolic diseases such as #obesity and #diabetes. Using genome sequencing of 320 individuals, the scientists have investigated how human populations have biologically adapted to the environments of the Pacific islands and how

Intermittent fasting and why when you eat makes a difference

“Intermittent #fasting” may help ward off #obesity, as expected. More speculatively, there are signs in animal studies that the regimens might also enhance athletic endurance and cognition, alleviate diabetes and perhaps even help combat other medical conditions. #intermittentfasting #CR #diet #nutrition https://www.washingtonpost.com/health/the-science-of-intermittent-fasting/2021/02/26/68f53c80-7546-11eb-948d-19472e683521_story.html

As you grow older, some preventive medical tests can be skipped

#aging patients still should have an annual “wellness” visit to check blood pressure, blood sugar (for the presence of Type 2 #diabetes), cholesterol, bone density (for #osteoporosis), #obesity and underweight (for frailty), skin (for cancerous lesions), #hearing, #vision and balance (to evaluate the risk of falls), and cognition. They also should keep up with certain #vaccinations, such as flu, shingles, tetanus and pneumonia. But they might be able to avoid certain tests if

Researchers identify bacteria that promote metabolic and mental health

Researchers identified Bifidobacterium longum APC1472 as regulator of appetite & metabolism. In overweight or obese people, the novel bacterial strain reduced fasting blood glucose levels & normalize levels of both ghrelin & the stress hormone cortisol. #microbiology #obesity #stress #diabetes https://medicalxpress.com/news/2020-12-bacteria-metabolic-mental-health.html
