All dietary fats are not created equal. Some types of fats have been linked to ailments like heart disease and diabetes, while others, like those often found in plants and fish, have well documented health benefits. So why do our bodies respond so destructively to some fats but not others? A new hypothesis described in latest issue of The Quarterly Review of Biology suggests the answer may lie in how different fats interact with the microbes in our guts. According to researchers from the University of New Mexico and Northwestern University, some fats may encourage the growth of harmful bacteria in the digestive system. Our bodies have evolved to recognize those fats and launch an immune response to preempt the impeding changes in harmful bacteria. The result is low-level inflammation that, over the long term, causes chronic disease.
