Trans Fats in Spanish Pastries and Their Influence on Mesenchymal Stem Cell Behavior In Vitro and Related Health...

Area of Science:

• Food Science and Technology
• Cell Biology
• Toxicology

Background:

• Trans fats (TFAs) are associated with chronic diseases and cellular dysfunction.
• Spain lacks effective regulations on TFAs in food products.
• Commercial pastries are a potential source of dietary TFAs.

Purpose of the Study:

• To analyze trans fat content in Spanish commercial pastries.
• To evaluate the biological impact of pastry-derived TFAs on mesenchymal stem cells (MSCs).
• To assess compliance with international trans fat guidelines.

Main Methods:

• Developed a novel method for fatty acid extraction from pastry samples.
• Analyzed trans fatty acid (TFA) levels using gas chromatography.
• Assessed MSC viability, adhesion, proliferation, and cytotoxicity via MTT assays and microscopy.
• Conducted dose-response experiments with pastry extracts.

Main Results:

• Significant variability in TFA levels was observed across pastry samples.
• TFAs exhibited dose-dependent negative effects on MSCs.
• Reduced MSC adhesion and proliferation, increased cytotoxicity were noted.
• TFA consumption impacts cellular health and growth mechanisms.

Conclusions:

• Spanish pastries contain variable levels of trans fats.
• Trans fats negatively impact mesenchymal stem cell function.
• Stricter regulatory frameworks are essential to monitor and limit TFA levels globally.
• Findings highlight potential health risks of excessive TFA consumption.
