Breaking News - Fish Oil May Be Harmful

Breaking News -  Fish oil is not as healthful as you think, study says

Fish oil is known for its plentiful health benefits. But new research suggests that the long-term consumption of fish oil or sunflower oil would  increase the risk of fatty liver disease later in life.
And how did they know this? By studying rats, researchers found that continous intake of sunflower oil or fish oil for over 10 years led to changes in the liver that make the organ vulnerable to non-alcoholic steatohepatitis (NASH).
NASH is a more serious form of non-alcoholic fatty liver disease (NAFLD).
Study co-author José Luis Quiles, a professor of physiology working at the University of Granada in Spain, and colleagues recently reported their findings in The Journal of Nutritional Biochemistry.
It is estimated that around 20 percent of people in the United States who have NAFLD also have NASH, and the condition becomes more common with age.
NASH is characterized by a buildup of fat in the liver — which is not caused by alcohol consumption — inflammation, and liver cell damage. The liver damage that occurs in NASH can increase the risk of liver cirrhosisand liver cancer.
Some of the key risk factors for NASH include overweight and obesityhigh blood pressure, high cholesterol, and type 2 diabetes, which are factors heavily influenced by diet.
The researchers came to their findings by analyzing the effects of different dietary fats, including sunflower oil, fish oil, and virgin olive oil, on rat livers.
In detail, the team looked at how lifelong intake of each of these oils impacted the structure of the rodents' livers, as well as their effects on gene expression, liver fibrosis (or scarring). 

The researchers not only found that liver fat accumulates with age, but they also revealed that the type of fat that builds up on the liver is influenced by the type of fats that we eat.
As Prof. Quiles points out, "[...] this means that, regardless of this accumulation, some livers age in a healthier way than others and with a greater or lesser predisposition to certain diseases."
The study revealed that fish oil and sunflower oil negatively impacted the liver health of the rats.
Lifelong sunflower oil intake was found to trigger liver fibrosis, and it also altered the structure of the organ, led to changes in gene expression, and increased oxidation in liver cells.
Olive oil, however, was found to cause the least damage to the liver.
These findings may come as a surprise; fish oil is the most commonly used natural product in the U.S. due to its frequently documented health benefits.
Still, this latest study certainly provides some food for thought when it comes to choosing which fats to include in the diet.
