An international group of scientists has shown that the long-term intake of fish oils can cause a number of alterations in the liver, which can lead to cirrhosis and cancer.
Published in the Journal of the American Medical Association (JAMA), the study was conducted by a team of researchers from the University of California, San Francisco (UCSF) and the Harvard School of Public Health (HSPH) in collaboration with the National Institute of Environmental Health Sciences (NIEHS).
The research was funded by the U.S. Department of Health and Human Services (DHHS) Environmental Protection Agency (EPA) Office of Research and Development (ORD) through a grant to the UCSF Institute for Health Metrics and Evaluation (IHME) at the Henry Ford Health System.
Can fish oil reduce fatty liver?
The aim of this study was to determine the effect of a high-dose (2.5 g/day) of EPA and DHA on serum lipids and lipoproteins in overweight and obese men and women. In this randomized, double-blind, placebo-controlled, crossover trial, participants were randomly assigned to receive either a low-fat diet (LFD) or a LFD supplemented with either 1.0 g EPA or 0.8 g DPA/d for 12 wk.
Blood samples were collected at baseline and at the end of each 12-wk intervention period. Lipids were ased by HPLC-MS/MS and lipid profiles were assessed by using the Friedewald equation. Serum total cholesterol, LDL-cholesterol, triglycerides, apolipoprotein B (apoB) and apoA-I were measured by radioimmunoas. Plasma concentrations of total and HDL cholesterol were determined by enzyme-linked immunosorbent as (ELISA).

Omega 3 fatty acids regulate important biological pathways, including the synthesis, oxidation, and breakdown of fats in the blood. One of the most significant of the omega 3 fatty acids is called DHA, and it plays a role in a variety of biological processes.
DHA is found in oily fish such as salmon – Check the list below

It is also found as a by-product of fish oil production, as well as in some processed foods. States, the average daily intake of omega-3 fats is about 2.5 grams per day, with most of this intake coming from fish.
Who should not take fish oil?
According to a new study, people using blood thinners, such as warfarin, should not take fish oil or other omega 3 supplements because of their increased risk of heart attack and stroke. The study, published in the journal Circulation: Cardiovascular Quality and Outcomes, looked at data from more than 1.5 million people who were followed for an average of 10 years.
The researchers found that people taking fish-oil supplements were more likely to have heart attacks and strokes than those who didn’t take the supplements, even after adjusting for other risk factors, including age, body mass index (BMI), smoking, diabetes, high blood pressure, and cholesterol levels. People who took fish oils were also at a higher risk for developing heart disease than the general population, the study found.

Is 1000mg fish oil too much?
Many doctors often recommend 1000 to 1200 mg of fish oil, because that amount of fish oil contains the total amount of Omega-3s the doctor recommends. The study also found no difference between the two groups in blood pressure, cholesterol, triglycerides, or blood sugar levels.
This study was not able to determine whether the difference was due to differences in fish consumption or other factors, such as age, sex, body mass index (BMI), smoking status, and other lifestyle factors.
It is important to note, however, that the results of this study were based on a very small number of people, so it is not possible to draw any firm conclusions about the health benefits of taking fish oils.
