Special Issue Information

Dear Colleagues,

This Special Issue explores the critical role that dietary fatty acids play in modulating gut microbiota and metabolites and their subsequent impact on metabolic health. The gut microbiota and their metabolites significantly influence host metabolism, immune function, and health. Dietary fatty acids, including saturated fats, monounsaturated fats, and polyunsaturated fats (PUFAs), affect the composition and function of gut microbiota and their metabolites in various manners.

Key Topics Covered:

  1. Types of Dietary Fatty Acids:

Saturated Fatty Acids (SFAs): typically found in animal fats and some plant oils, SFAs can alter the gut microbiota composition, often leading to reduced microbial diversity and increased inflammation, contributing to metabolic disorders like obesity and insulin resistance.

Monounsaturated Fatty Acids (MUFAs): present in olive oil and avocados, MUFAs are associated with beneficial effects on gut microbiota, promoting microbial diversity and reducing inflammation.

Polyunsaturated Fatty Acids (PUFAs): Including omega-3 and omega-6 fatty acids, PUFAs play a crucial role in maintaining gut health. Omega-3 fatty acids, found in fish oil and flaxseed, have anti-inflammatory properties and affect gut microbiota metabolites. Conversely, excessive omega-6 fatty acid intake, common in processed foods, can promote inflammation and negatively affect gut health.

  1. Topics of health implications:

The research topics on health implications can cover various aspects, which are briefly outlined below. These topics focus on the regulation of chronic diseases such as obesity, metabolic syndrome, inflammatory diseases, cardiovascular diseases, stroke, hepatic diseases, renal diseases, and more.

Conclusion:

This Special Issue emphasizes the importance of dietary fatty acids in the modulation of gut microbiota and metabolites and influencing metabolic health. It underscores the need for balanced dietary fat intake to promote a healthy gut microbiome and reduce the risk of metabolic and inflammatory diseases.

Dietary lipid intake can influence the gut microbiota (GM) and their metabolites, such as short-chain fatty acids (SCFA) and bile acids, which are key mediators of health. The objective is to examine how dietary lipids’ quantity and quality influence the GM and metabolite profiles. A literature review of 33 studies in animals and humans was performed on the effects of saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), polyunsaturated fatty acids (PUFAs), trans-fatty acids (TFAs), and sterols on GM composition and gut-derived metabolites. The results show that diets rich in MUFAs, n-3 PUFAs, and short-chain FAs have the potential to enhance beneficial bacteria and metabolites. In addition, trans-palmitoleic acid, conjugated linoleic acid, and phytosterols may also have potentially beneficial effects on GM, but more research is needed. Medium-chain FAs and n-6 PUFAs have variable effects on the GM. Conversely, intakes of high-fat diets, long-chain SFAs, industrial TFAs, and cholesterol disrupt GM balance. In conclusion, animal studies clearly demonstrate that dietary fats influence the GM and related metabolites. Yet, human studies are limited. Therefore, well-designed human studies that consider the whole diet and baseline health status are needed to better understand the effects of dietary lipids on GM. Full article
