Are You Getting Enough Omega-3s? 85% of People Aren’t

Summary: A new study warns of a global omega-3 deficiency affecting 85% of people worldwide. Environmental damage, overfishing, and dietary imbalance are to blame. Scientists urge action to improve access to clean, omega-3-rich foods and restore balance with omega-6s to lower the risk of chronic diseases like heart disease, cancer, and mental health issues.

Global Omega-3 Deficiency Puts Health at Risk

Omega-3 deficiency is quietly becoming a global health crisis, and most of us don’t even realise it. According to a new study by Case Western Reserve University, a staggering 85% of the world’s population isn’t getting enough omega-3 fatty acids in their diets. These essential nutrients play a key role in brain, heart, and endocrine health, yet our modern food systems are failing to deliver them.

“Our current food systems are not providing enough uncontaminated omega-3,” said Timothy Ciesielski, lead researcher and scientist at the university’s School of Medicine.
“And our access is expected to decrease in the near future.”

Let’s explore what omega-3s do, why they’re vanishing, and how we can fix this global imbalance.

Why Omega-3 Fatty Acids Are Vital for Your Body

Omega-3 polyunsaturated fatty acids are essential fats that support:

Brain and eye development
Cardiovascular and endocrine function
Cellular health and energy production

Since our bodies can’t make enough omega-3s naturally, we must rely on food sources to meet our needs, like

Fatty fish (salmon, sardines)
Flaxseeds
Chia seeds
Supplements

The Alarming Global Shortage of Omega-3s

The study, published in AJPM Focus, found that environmental challenges are contributing to a global omega-3 shortage:

Rising ocean temperatures
Overfishing
Pollution

This means not only are fewer people able to access omega-3-rich foods, but even the foods available may be contaminated or nutritionally compromised.

“This has serious and widespread health implications,” Ciesielski warned.
“This isn’t just a healthcare issue; it’s a public health and environmental challenge.”

The Omega-6 Imbalance: A Modern Problem

Historically, humans ate diets with a healthy balance of omega-3 to omega-6 fatty acids. But today’s diets, especially in industrialised nations, contain about 20 times more omega-6s than omega-3s. This imbalance can fuel chronic inflammation, leading to:

Heart disease
Cancer
Preterm birth
Mental health disorders

Reducing omega-6 intake (found in vegetable oils and processed foods) and increasing omega-3 consumption is crucial.

How Oceans and Sustainability Affect Omega-3 Access

Only about 15% of countries currently meet the recommended omega-3 intake levels, mostly those with direct ocean access. This suggests that:

Protecting marine ecosystems
Sustainable fishing
Investing in algae-based omega-3 sources

…could help secure a cleaner, more reliable supply of this essential nutrient.

“Everyone should have the right to uncontaminated omega-3s in their diet,” said Ciesielski.
“These are important questions that require our collective attention and action.”

What You Can Do to Protect Your Health

Eat more omega-3-rich foods: salmon, mackerel, walnuts, flaxseeds, chia seeds
Cut down on omega-6s: avoid vegetable oils and highly processed snacks
Choose clean, sustainable omega-3 supplements
Support environmental policies that protect oceans and regulate overfishing

Conclusion: This Is a Wake-Up Call for Us All

The omega-3 crisis isn’t just about diet, it’s about

Global health
Food security
Environmental sustainability

If 85% of people aren’t getting enough, we need to rethink our food systems, protect marine sources, and reclaim nutritional balance in our diets.

Because when omega-3 levels fall, the risk of disease rises and that affects all of us.
