1. A significant difference exists between the fecal microbiota of hospital-born infants versus home-born infants, and the differences persist well into the first month of life. The study included 35 vaginally born, breast-fed neonates, 14 who were delivered at home and 21 who were delivered in the hospital. Eight maternal and infant feces samples were […]

1. Do you struggle to lose weight? Your microbiome could have something to do with it. A recent study implemented a 3-month lifestyle intervention in 26 overweight and obese adults (aged 18 to 65) and compared weight loss success (defined as losing 5% or more of baseline body weight) with microbial composition. Results showed an […]

1. Beneficial gut bacteria help determine our ability to fight off infection, but how? Scientists discover that gut bacteria communicate with immune cells and cells lining the intestinal wall to regulate the immune system’s response to infection. Beneficial gut bacteria are responsible for attaching to the intestinal wall and signaling the cellular production of IL-10, […]

1. Prebiotic supplementation could replace the low FODMAPs diet as a treatment for functional gut disorders (IBS, constipation, functional dyspepsia, etc.). A 4-week study compared the effects of a prebiotic supplement plus Mediterranean-type diet, versus a placebo supplement plus low FODMAP diet for 2 weeks. Fecal microbiota composition, intestinal gas production, and digestive sensations were measured […]

1. Intermittent fasting (typically defined as going 12 to 18 hours a day without food) positively impacts the gut microbiome and protects against central nervous system (CNS) autoimmunity.  A recent study in mice found that IF increases gut bacteria richness and diversity (resulting in an increase in Lactobacillaceae, Bacteroidaceae, and Prevotellaceae families), and positively alters […]

1. Weight gain and metabolic dysfunction in adulthood could be linked to maternal omega-3 fatty acid intake during gestation and lactation. A recent mouse study found that maternal PUFA (polyunsaturated fatty acid) production during pregnancy and nursing significantly reduced weight gain and markers for metabolic dysfunction in male offspring fed a high fat diet. The […]

1. 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 […]

1. Cancer risk in the distal colon in women is lower in those who avoid eating red meat. In a 17-year study in over 32,000 women, researchers found that those women who did not eat red meat had a reduced risk of distal colon cancer. A red meat-free diet was not protective against cancer elsewhere […]

1. 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 […]
