Fish oils may halt negative effects of junk food

29 May 2013

A new study has revealed that fish oil can minimise, and possibly even reverse, junk food’s negative effect on the brain.

The healthcare research, conducted by scientists at the University of Liverpool, analysed 185 previous related studies. Experts concluded that fish oil plays a significant role in weight loss efforts by stimulating a part of the brain that regulates food intake.

High-fat, calorie-laden junk food has been found to disrupt neurogenesis, a process that creates new nerve cells. Fish oils, which are rich in omega-3s, minimise this effect. Additionally, they help the brain regain control of feeding and appetite.

Lead researcher, Dr Lucy Pickavance, said the nutrient is crucial for dieters hoping to lose weight. Meanwhile, “excessive intake of certain macronutrients, the refined sugars and saturated fats found in junk food, can lead to weight gain, disrupt metabolism and even affect mental processing”. Fish oils themselves don’t cause weight loss, but “they may take the brakes off the detrimental effects of some of the processes triggered in the brain by high-fat diets”, Dr Pickavance said.

A number of nutrient shortages, including a lack of omega-3s, can cause health problems. Have a one-off mineral level test to determine whether an iron, vitamin B or calcium deficiency negatively impacting your health.
