Early-life antibiotic exposure can disrupt the founding intestinal microbial community and lead to obesity later in life. Recent studies show that omega-3 fatty acids can reduce body weight gain and chronic inflammation through modulation of the gut microbiota.
We hypothesize that increased tissue levels of omega-3 fatty acids may prevent antibiotic-induced alteration of gut microbiota and obesity later in life.
Here, we utilize the fat-1 transgenic mouse model, which can endogenously produce omega-3 fatty acids and thereby eliminates confounding factors of diet, to show that elevated tissue levels of omega-3 fatty acids significantly reduce body weight gain and the severity of insulin resistance, fatty liver and dyslipidemia resulting from early-life exposure to azithromycin.
These effects were associated with a reversal of antibiotic-induced dysbiosis of gut microbiota in fat-1 mice.
These results demonstrate the beneficial effects of omega-3 fatty acids on antibiotic-induced gut dysbiosis and obesity, and suggest the potential utility of omega-3 supplementation as a safe and effective means for the prevention of obesity in children who are exposed to antibiotics.
