Lactobacilli and Bifidobacterium as anti- atherosclerotic agents

Atherosclerosis is the thickening or hardening of the arteries which is caused by a buildup of atheromatous plaque in the inner lining of an artery. Hypercholesterolemia, inflammation, oxidative stress, and trimethylamine N-oxide (TMAO) are important risk factors for atherosclerosis. Therefore, this study aimed to review the anti-atherosclerotic effects of Lactobacilli and Bifidobacterium via improving lipid profile and reducing the effects of oxidative stress, inflammation, and TMAO. To prepare the present review, several databases such as Scopus, PubMed, and Google Scholar were searched, and relevant articles from ۱۹۹۰ until ۲۰۲۲ were selected and reviewed. The present review showed that Lactobacilli and Bifidobacterium reduce the risk of atherosclerosis in both in vitro and in vivo studies by breaking down or altering cholesterol metabolism with the help of their by-products and by reducing inflammation and oxidative stress and TMAO. Consumption of Lactobacilli and Bifidobacterium can be useful in prevention of atherosclerosis.
