Sepsis Worsens With Western-style Diet

High fat diets result in a severe overreaction of the immune system to sepsis, discloses an experimental study done on mice.

The study has shown that a diet high in saturated fat, sugars and cholesterol greatly exaggerates the inflammatory response to sepsis.

Macrobiotics is an Oriental theory that lays down guidelines for promoting well-being and longevity through systematic diet consisting mainly of whole grains and beans.

"Mortality due to sepsis in morbidly obese subjects is estimated to be 7 times more prevalent compared to mortality in lean individuals. Morbidity in obese patients is also more severe," said Chantal Rivera of the Louisiana State University Health Sciences Center-Shreveport.

"Results from our recent studies suggest that this adverse outcome may be caused by consuming a high-fat diet, which predisposes the immune system to react more strongly to infection," he said.

Rivera lead a team of researchers to carry out the surgical induction of sepsis in mice that had been fed normal chow or western diet for 3 weeks.

Obesity - Causes, Symptoms, Diagnosis, Complications, Treatment
Obesity is a condition where there is excess accumulation of body fat which poses a risk to the health of the individual. It can affect children and adults.

Mice on the western diet, which was enriched in saturated fat, showed exacerbated inflammation that was found to be mediated by signalling via the toll-like receptor 4 (TLR-4) pathway.

"These results suggest that targeting the TLR signaling pathway as a therapeutic approach to the medical management of sepsis may be especially beneficial in obese patients," said Rivera.

Look Out For Sepsis
Researchers at the critical care centre felt that, everyone should be aware of the dangers of sepsis, a life-threatening response to infection.

The findings were published in the journal BMC Physiology.
