The gut microbiota is a central regulator of host metabolism. The composition and function of the gut microbiota is dynamic and affected by diet properties such as the amount and composition of lipids. Hence, dietary lipids may influence host physiology through interaction with the gut microbiota. Lipids affect the gut microbiota both as substrates for bacterial metabolic processes, and by inhibiting bacterial growth by toxic influence. The gut microbiota has been shown to affect lipid metabolism and lipid levels in blood and tissues, both in mice and humans. Furthermore, diseases linked to dyslipidemia, such as non-alcoholic liver disease and atherosclerosis, are associated with changes in gut microbiota profile. The influence of the gut microbiota on host lipid metabolism may be mediated through metabolites produced by the gut microbiota such as short-chain fatty acids, secondary bile acids and trimethylamine and by pro-inflammatory bacterially derived factors such as lipopolysaccharide. Here we will review the association between gut microbiota, dietary lipids and lipid metabolism.

Phytic acid (PA) or myoinositol intake was recently reported by our group to suppress hepatic lipogenic gene expression and modulate gut microbiota in rats fed a high-sucrose diet (HSC). The aim of th...
Increasing evidence has indicated an association between gut microbiota in gastrointestinal cancer and clinical outcome. Herein, we aim to develop a prognosis-prediction tool based on an immune-lipid ...
Dietary fatty acids can accumulate in sperm and affect their function in vertebrates. As Drosophila melanogaster shares several pathways of lipid metabolism and shows similar lipid-dependent phenotype...
Most current knowledge about plant lipid metabolism has focused on the biosynthesis of lipids and their transport between different organelles. However, lipid composition changes during development an...
Microwave radiation can lead to some biological effects, mainly involving the nervous and reproductive systems. However, its lipid metabolic mechanism remains unclear. Here, we performed an untargeted...
Individuals submitted to a high-fat or a high-fructose/sucrose diet develop, over a 6 day-period, several features of the metabolic syndrome, including increased plasma triglycerides, incr...
The purpose of this study is to examine whether the daily consumption of 5 g of milk polar lipids influences serum lipids and gut microbiota composition in healthy adults.
To assess the extent to which consumption of different sources of hydrogenated fat relative to unhydrogenated oil or butter alters plasma lipoprotein concentrations and measures of lipid m...
Modern way of life characterized by decreased physical activity and poor dietary habits seems to be an important trigger for the onset of metabolic disorders. Accumulating evidence indicat...
It has become apparent that many cancers depend on specific fats (lipids) for their continued growth. Conjugated linoleic acid (CLA) is a safe, popular, and well-tolerated dietary suppleme...
The metabolic process of breaking down LIPIDS to release FREE FATTY ACIDS, the major oxidative fuel for the body. Lipolysis may involve dietary lipids in the DIGESTIVE TRACT, circulating lipids in the BLOOD, and stored lipids in the ADIPOSE TISSUE or the LIVER. A number of enzymes are involved in such lipid hydrolysis, such as LIPASE and LIPOPROTEIN LIPASE from various tissues.
Dynamic cytoplasmic organelles found in almost all cells. They consist of a central core of LIPIDS surrounded by a phospholipid monolayer studded with surface proteins, and are involved in LIPID METABOLISM and storage.
Substances that alter the metabolism of LIPIDS.
Errors in the metabolism of LIPIDS resulting from inborn genetic MUTATIONS that are heritable.
Physiological processes in biosynthesis (anabolism) and degradation (catabolism) of LIPIDS.
Hepatology is the study of liver, gallbladder, biliary tree, and pancreas, and diseases associated with them. This includes viral hepatitis, alcohol damage, cirrhosis and cancer. As modern lifestyles change, with alcoholism and cancer becoming more promi...
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
