Gut bacteria play a leading role in how well cancer drugs work. Certain gut bacteria (Bifidobacterium specifically) boost people’s response to cancer treatment while others can make immunotherapy ineffective. In addition, previous studies show that those with antibiotic exposure are more likely to have a poor response rate to immunotherapy. Researchers are now testing how to […]
A ketogenic diet (KD) improves neurovascular pathways that play key roles in brain function and beneficially alters the gut microbiome. The study included a 16-week ketogenic diet and was conducted in young, healthy mice aged 12 to 14 weeks. In addition to improved neurovascular function, a KD reduced blood glucose levels and body weight and showed […]
Patterned hair loss could be due to gut bacteria imbalance. Antibiotic-induced dysbiosis, characterized by an overgrowth of Lactobacillus murinus (a gut bacteria strain that depletes biotin – vitamin B7, a nutrient associated with hair growth), in mice fed a biotin deficient diet altered gut metabolic function and resulted in alopecia (or hair loss). When consuming a […]
Is your microbiome test giving you an accurate picture? A recent study looked at one of the most well known markers of microbial health – bacterial diversity. The researchers found that taking 5 fecal samples over 5 consecutive days portrays a more accurate picture of microbial diversity than just 1 sample. This study also concluded that when […]
Artificial sweeteners promote dysbiosis (imbalanced gut bacteria) in Crohn’s disease (CD) patients and may worsen the disease and its symptoms. In a series of 3 studies, scientists mixed a low dose of Splenda into the drinking water of mice (who originated from a genetic line of mice with CD). They increased the dose slightly for the […]
High processed salt intake alters gut bacteria composition and may disrupt the relationship between the microbiome and host homeostasis. While increased salt intake is a risk factor for cardiovascular disease (CVD), we’re not exactly sure why that is. A recent study gave rats either water or a salt-water solution over a two-week period and analyzed blood […]
Initiating an intrauterine device (IUD) with copper over a 180-day period significantly increased the prevalence of bacterial vaginosis (BV) in a group of women seeking contraception in Zimbabwe, while hormonal contraceptive methods did not affect BV prevalence. In the 234 women using the copper IUD, BV prevalence was assessed at baseline and at 30, 90 […]
Studies show that overweight mothers are more likely to have overweight children, but why? A recent study, looking at 935 mother-infant pairs, found that infants born vaginally to overweight mothers were 3 times more likely to be overweight by the age of 3 when compared to infants born from normal weight mothers. Those born via C-section […]
