A global shortage of omega-3 fatty acids may be putting billions at risk for health problems, according to a research study from Case Western Reserve University.
Omega-3s, primarily found in fish and some plants, are essential for brain, eye, cardiovascular and endocrine health. However, the human body cannot produce enough on its own, so we must get it from food or supplements.
“Our current food systems are not providing enough uncontaminated omega-3,” said Timothy Ciesielski, a research scientist at the university’s School of Medicine. “Access is expected to decrease in the near future.”
The research
The study, published in AJPM Focus, found that 85% of the global population fails to meet recommended omega-3 intake levels. Environmental stressors, including rising ocean temperatures, overfishing and pollution, are contributing to the shortage of omega-3. Only about 15% of countries currently meet sufficient omega-3 levels, mostly due to ocean access.
Researchers recommend increasing production of omega-3-rich foods and reducing consumption of omega-6 fatty acids, which are overrepresented in modern diets and may interfere with omega-3 absorption. Doing so can lower the risk of diseases related to chronic inflammation, such as heart disease, cancer, preterm birth and some mental-health issues, the researcher noted.
“This isn’t just a healthcare issue; it’s a public health and environmental challenge,” Ciesielski said. “Everyone should have the right to uncontaminated omega-3s in their diet. These are important questions that require our collective attention and action.”
