Interesterified palm oil promotes insulin resistance and altered insulin secretion and signaling in Swiss mice.

Interesterified fats have been used to replace trans-fat in ultra-processed foods. However, their metabolic effects are not completely understood. Hence, this study aimed to investigate the effects related to glucose homeostasis in response to interesterified palm oil or refined palm oil intake.

Interesterified palm oil increases intestinal permeability, promotes bacterial translocation, alters inflammatory parameters and tight-junction protein genic expression in Swiss mice.

High-fat diets seem to have a negative influence on the development of obesity and the processes associated with low-grade chronic systemic inflammation. In recent years, partial hydrogenated oil, rich in trans isomers, has been associated with deleterious health effects. It has been replaced by interesterified fat (IF).

Wheat gluten intake increases the severity of experimental colitis and bacterial translocation by weakening of the proteins of the junctional complex.

Gluten is only partially digested by intestinal enzymes and can generate peptides that can alter intestinal permeability, facilitating bacterial translocation, thus affecting the immune system. Few studies addressed the role of diet with gluten in the development of colitis. Therefore, we investigate the effects of wheat gluten-containing diet on the evolution of sodium dextran sulphate (DSS)-induced colitis.
