Fat intake and inflammation -

For the UC Davis Health study, which used a mouse model, Hwang and his colleagues found that a diet containing both high fat and high sugar mimicking the Western diet in humans was required to induce observable skin inflammation.

In four weeks only, mice on Western diet had significantly increased ear swelling and visible dermatitis compared to mice fed a controlled diet and those on high fat diet alone. The study detailed the mechanisms by which inflammation happens following a Western diet.

It identified bile acids as key signaling molecules in the regulation of skin immunity. Bile acids are produced in the liver from cholesterol and metabolized in the intestine by the gut microbiota.

They play an important role in dietary lipid absorption and cholesterol balance in the blood. The study found that cholestyramine, a drug used to lower cholesterol levels by binding to bile acids in the intestine, helped reduce the risk of skin inflammation.

The finding suggests that bile acids mediate the development of psoriasis. The binding of cholestyramine to bile acids in the gut and its subsequent release through the stool allows for lowering of skin inflammation.

Further studies are needed to understand the mechanism behind diet-induced skin inflammation and the interaction between metabolism, microbes and immunity. Other collaborators include Xuesong Wu, Mindy Huynh and Mimi Nguyen from Department of Dermatology at UC Davis, Prasant Jena and Yui-Jui Yvonne Wan from Medical Pathology and Laboratory Medicine at UC Davis and Sebastian Yu from Department of Dermatology at Kaohsiung Medical University.

Although there were no major changes in the overall volume of gut bacteria among the three groups, the numbers of beneficial bacteria that produce short chain fatty acids, including butyrate, had increased in the low fat diet group. Butryate is a key energy source for bowel cells and has anti-inflammatory properties.

Certain bacteria, such as Blautia species, which were associated with lower cholesterol levels, were abundant among those on the low fat diet.

Bacteroides species, which were associated with higher cholesterol levels, were more common among those on the high fat diet. The opposite was true for the low fat diet. The researchers emphasise that sampling was only done at the start and finish of the trial, and a more complete picture of microbial changes would have emerged with more frequent sampling.

But the findings do seem to illustrate the need to curb dietary fat intake, they suggest. But their findings might also have implications for other countries, they suggest.

High fat diet linked to unfavourable changes in gut bacteria and inflammatory triggers. High fat diet linked to unfavourable changes in gut bacteria and inflammatory triggers May sow seeds for metabolic disorders and cardiovascular disease over longer term A high fat diet is linked to unfavourable changes in the type and numbers of gut bacteria—collectively known as the microbiome—as well as a rise in inflammatory triggers in the body, finds the first study of its kind, published online in the journal Gut.

Obesity plays a Fat intake and inflammation role in the development of low-grade inflammation. Dietary fatty acids are important modulators of inflammatory responses. Saturated fatty acids SFA and n-6 polyunsaturated fatty acids PUFA have been reported to exert pro-inflammatory effects.
