Antimicrobial Eats: How Food Additives are Contributing to Obesity via the Gut Microbiome

The typical modern diet is brimming with food additives used in food processing. Additives such as antibiotic residues, GMOs, pesticide residues, anti-caking agents, emulsifiers, artificial sweeteners, colorants, flavor enhancers, and preservatives. Most of these additives seem to shift the gut microbiome towards more pro-inflammatory signals. When all these additives are considered as an amalgam, such as with the modern processed diet, the ramifications on the gut microbiome are concerning. Obesity, which is characterized by low-level chronic inflammation, is likely exacerbated by these food additives. Consequently, most of these additives should be avoided or banned for optimal health.
