How fatty food in old age affects the heart

Broken red heart with a bandaid and Heart Attack text

UNITED STATES (VOP TODAY NEWS) — Omega acids are known to be different. We usually lack omega-3 acids . But omega-6 acids are consumed in excess: they are found in such common foods as chicken and turkey meat, margarine and mayonnaise, sunflower seeds and peanut butter.

Ideally, the ratio of omega-6 and omega-3 in the diet should be 4: 1, but in practice it is usually 20: 1. And it is especially dangerous for an aging body.

Researchers from the Autonomous University of Barcelona decided to find out how a diet with a surplus of omega-6 affects the intestinal microbiome and the profile of spleen leukocytes.

The spleen, a secondary immune organ, is a reservoir for leukocytes that are released after damage to the heart, for example, due to a heart attack. Spleen leukocytes rush to the heart to begin tissue repair and remove inflammation.

Scientists conducted experiments on mice and saw that a high-fat diet caused a sharp growth of bacteria belonging to the genus Allobaculum , type Firmicutes . Also, in all experimental mice an increase in the level of neutrophils, structural deformities of the spleen and a decrease in the CD169-positive splenic macrophages were recorded.

It was found that a diet with an excess of omega-6 due to deformations occurring in the spleen, and changes in the microbiome worsens the processes of recovery of cardiac tissue.

No less important was the influence of age. Thus, the organisms of young mice during testing still managed to cope with the harmful effects of fatty foods . But the organisms of older mice could not overcome it – they had irreversible inflammation associated with the development of acute decompensated heart failure.

According to scientists, this study emphasizes that diet and age are critical factors affecting the health of the heart and the whole body. Scientists urge to abandon fatty foods as they age — even if in youth it didn’t bring much damage, over the years this diet becomes truly dangerous.
