Cardiovascular diseases continue to be the leading cause of death worldwide. Research studies have emphasized the significant association between cardiovascular toxicity and dietary patterns as well as inflammatory processes; these factors critically influence cardiovascular health and contribute to major cardiovascular risk factors such as Type 2 diabetes Mellitus (T2DM) and obesity. Recent studies have elucidated a causal link between gut microbiota and cardiovascular toxicity, operating either directly or via its metabolic products. The intricate interplay between dietary intake, the gut microbiome, and the host’s immune response presents a fascinating and complex puzzle. This complexity is further heightened because the underlying mechanisms driving inflammation and their contribution to cardiovascular pathologies remain incompletely defined. This discussion will delve into these interconnected components and the mechanisms by which they instigate cardiovascular toxicity and related diseases.
