The study found that “certain types of n-3 (from marine oils) were significantly associated with a decreased risk of having asthma or asthma-like symptoms by up to 62 per cent, while high n-6 consumption (from vegetable oils) was associated with an increased risk by up to 67 per cent,” said Andreas Lopata, Professor from the James Cook University in Australia. For the study, the team included 642 people who worked in a fish processing factory in a village in South Africa.
“Even if you factor in contaminants, such as mercury found in some fish populations, the benefits of fish and seafood intake far more outweighs the potential risks,” Lopata said, in the paper published in International Journal of Environmental Research and Public Health.
