Global Omega-3 Deficiency Raises Health and Environmental Concerns

A new study from Case Western Reserve University warns of a growing global deficiency in omega-3 fatty acids, essential nutrients the body cannot produce on its own. Found mainly in fish and some plants, omega-3s are critical for brain, eye, heart, and endocrine health. Researchers found that 85% of the world’s population lacks sufficient omega-3 intake, largely due to environmental issues like ocean warming, pollution, and overfishing, which reduce access to uncontaminated sources.

The study urges increased production of omega-3-rich foods and a reduction in omega-6 intake, as modern diets now contain 20 times more omega-6s, disrupting the omega-3 balance and raising the risk of diseases tied to chronic inflammation, including heart disease and cancer.

Only 15% of countries meet sufficient intake levels, mostly those with ocean access. Experts emphasize the need for sustainable ocean protection and public health efforts to address this growing nutritional crisis.
