Hair Loss Linked To Gut Bacteria Imbalance
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 […]
Does Microbiome Testing Offer An Accurate Picture?
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 […]
Lot of white capsules on a blue background. Medical background.
The question we’re all wondering as we pop our daily probiotic – is probiotic supplementation in healthy adults helpful, or is it all hype? A 2018 review of probiotic supplementation in healthy adult populations analyzed the literature published between 1990 and August 2017. The review included 45 studies. Results showed that probiotic supplementation can lead to […]
Wooden spoon with salt and rosemary on a dark background. Macro.
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 […]
A Popular Birth Control Method Linked To Bacterial Vaginosis
 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 […]

Nitrate in drinking water, even at safe levels (within 50 mg nitrate/liter of water), increases colorectal cancer (CRC) risk. Scientists assessed drinking water nitrate level exposure in 2.7 million adults and examined 200,000 drinking water analyses from 1978 to 2011 in Denmark. Comparing this data with population-based health registry data, scientists identified 5,944 CRC cases. Analysis […]
Woman cleaning and polishing the kitchen worktop with a spray detergent, housekeeping and hygiene concept
A 20-year long study, including 6,235 participants with an average age of 34, uncovers the long-term impact of spray cleaners on lung function in women. The study found that women who regularly clean with cleaning sprays experience worsening of lung function over time when compared to women who don’t clean. To put the findings in more […]
