Eating Oily Fish Can Help Reverse Junk Food’s Harm to Immunity


The logic is simple to follow: Eating too much “junk food” leads to increase fat deposits in the body which suppresses the body’s production of antibodies, thus impairing immunity. But in a world where junk food is sometimes hard to avoid, it’s good to know that just two servings of oily fish per week may help reverse the damage.

Obesity’s damage to the immune system makes fighting viruses and bacteria more difficult, as well as increases the risk of serious diseases such as cancer, type 2 diabetes, stroke and coronary heart disease — the harmful effects are similar to those associated with aging.

In the study conducted at John Moores University in Liverpool, the immunity-boosting effects of two supplements were tested. Thirty-two mice were fed obesity promoting diets, resulting in the inadequate production of antioxidants, along with aging of the immune system. The mice were then divided into two groups that were given supplements of either omega-3 fatty acids or 2-hydroxyoleic acid, a synthetic compound from oleic acid.

After eight weeks, an examination of the rodents’ spleens showed that both supplements decreased the effects of obesity on the immune system. The group that was fed 2-hydroxyoleic acid improved the most.

“This is the first study, at least to our knowledge, to suggest the efficacy of 2-hydroxyoleic acid for reversing obesity-associated immune alterations and improving oxidative stress,” said study author Dr. Fatima Perez de Heredia.

People can eat two portions of fish per week, one being oily, to receive the benefits of 2-hydroxyoleic acid, advised de Heredia. “The Mediterranean diet of two fish portions a week is a good place to start,” she added.

The study was published in the journal Experimental Physiology.

These findings come on the heels of a 2016 study that found eating small amounts of oily fish after a bowel cancer diagnosis may reduce the risk of death by 70 percent. Unquestionably, eating fish varieties, such as salmon, trout, mackerel and tuna, is one of the most healthful ways to improve your diet.
