Combating childhood obesity by preventing ‘fatty liver’ in fetus
New research published in The Journal of Physiologyindicates that an obese pregnant mother and exposure to a high fat, high sugar diet during pregnancy produces a "fatty liver" in the fetus, potentially predisposing children to obesity, metabolic and cardiovascular disorders later in life. The research aims to understand the cellular mechanisms involved in laying down fat in … [Read more...]
