Anti-inflammatory and antioxidant activity of functional lipids extracted through sustainable technologies from Mexican Opuntia ficus-indica seeds.

Opuntia ficus-indica (OFI) seeds are a rich source of functional lipids, yet research on Mexican cultivars remains limited. This study evaluated the antioxidant and anti-inflammatory properties of lipids extracted through subcritical fluid and supercritical fluid extraction with carbon dioxide (SCE-CO₂ and SFE-CO₂) from Mexican OFI Villanueva and Rojo Vigor seeds with and without enzymatic pretreatment. SCE OFI Villanueva oil showed higher extraction efficiency of linoleic (45.

Functional foods lipids: unraveling their role in the immune response in obesity.

Functional lipids are lipids that are found in food matrices and play an important role in influencing human health as their role goes beyond energy storage and structural components. Ongoing research into functional lipids has highlighted their potential to modulate immune responses and other mechanisms associated with obesity, along with its comorbidities. These lipids represent a new field that may offer new therapeutic and preventive strategies for these diseases by understanding their contribution to health.

Polyphenol Bioaccessibility and Antioxidant Activity of Pomegranate () Peel Supplementation in Diet-Induced Obese Rats.

Fruit by-products are a source of biocompounds with antioxidant properties and potential role in the obesity treatment. This study aimed to assess the effect of pomegranate () peel (PP) supplementation on the total antioxidant capacity (TAC) in diet-induced obese rats. Thus, an gastrointestinal digestion was performed to evaluate the total phenolic content (TPC) and the antioxidant capacity of PP.

Characterization of the Cafeteria Diet as Simulation of the Human Western Diet and Its Impact on the Lipidomic Profile and Gut Microbiota in Obese Rats.

The obesity pandemic has been strongly associated with the Western diet, characterized by the consumption of ultra-processed foods. The Western lifestyle causes gut dysbiosis leading to impaired fatty acid metabolism. Therefore, this study aimed to evaluate shifts in gut microbiota and correlate these with serum fatty acid profiles in male Wistar rats fed a cafeteria diet.
