Omega-3 and omega-6 fatty acids are "healthy fats" and essential for human health.
A higher consumption of omega-3 and omega-6 fatty acids may help ward off a variety of cancers, finds a study of more than 2,50,000 people on Tuesday. Cancer has become a global health concern, especially with increasing early onset.
Omega-3 and omega-6 fatty acids are
"healthy fats" and essential for human health. These are important to
the cells and are known to reduce bad cholesterol levels, keep the brain
healthy and boost mental health. Higher levels of omega-3s showed protection
against colon, stomach and lung cancer, according to the study, published in
the International Journal of Cancer.
On the other hand, high omega-6 levels
protect against brain, malignant melanoma, bladder and 14 different cancers.
"Higher omega-3 and omega-6 levels were associated with lower rates of
cancer," said lead author Yuchen Zhang, a doctoral student at the
University of Georgia's College of Public Health.
Zhang noted that with the significant rise
in cancers worldwide, the study “suggests that the average person should focus
on getting more of these fatty acids in their diets.”
The researchers analysed data from more
than 2,50,000 people, of which about 30,000 developed some form of cancer in
the 10 years of follow-up.
Omega-3 and omega-6 are present in fatty
fish, nuts and even some plant oils. However, as diets may not provide the
recommended amounts, people often turn to fish oil supplements — one of the
most popular dietary pills on the market. However, it may not be suitable for
all, said the researchers.
