TV Doctor Warns of Widespread Omega-3 Deficiency in Modern Diets
Prominent GP and television personality Dr Amir Khan has issued an urgent health recommendation, urging the public to consider daily omega-3 supplementation due to what he describes as a widespread nutritional deficiency with potentially serious long-term consequences.
The Essential Nutrient Most People Are Missing
In a recent social media video that has garnered significant attention, Dr Khan, familiar to viewers from his regular appearances on ITV's Good Morning Britain and Lorraine, addressed a critical gap in modern nutrition. "Can we talk about omega-3 fatty acids?" he began. "They're one of those nutrients everyone's heard of but most people aren't actually getting enough of."
The doctor, who practices at the Ridge Medical Centre in Bradford, West Yorkshire, emphasised that this deficiency extends even to those who believe they maintain relatively healthy eating habits. He explained that omega-3s are essential fats, meaning the human body cannot produce them independently; they must be obtained through diet or supplementation.
Why Omega-3s Are Crucial for Brain and Body
Dr Khan detailed the multifaceted importance of these fatty acids, stating they are especially vital for brain health, but also play significant roles in cardiovascular function, eye health, inflammation reduction, and even mood regulation. He specifically highlighted two marine-based omega-3s: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid).
"DHA is a major building block for the brain," he explained. "It literally helps your brain cells communicate properly. So, if you're not getting enough over time, that can affect things like your concentration, your memory, your mood and even your long-term brain health."
The Modern Diet Problem and Supplement Solutions
The GP identified several factors contributing to the common shortfall. Firstly, most people do not consume enough oily fish—such as salmon, sardines, or mackerel—which are primary natural sources of EPA and DHA. Secondly, modern diets are overloaded with ultra-processed foods high in omega-6 fats, which can "crowd out" the beneficial omega-3s.
For those who do not eat fish, Dr Khan presented a compelling alternative. "Omega-3s start with algae - the fish just pass them on," he revealed. "That's why algae based omega-3 supplements also exist and, yes, they work great - I take them." He noted these plant-based supplements provide DHA and EPA directly and are an excellent option for vegetarians and vegans.
While he endorsed plant foods like flax seeds, chia seeds, and walnuts (which contain ALA, a precursor omega-3), he cautioned that the body's conversion of ALA to the more beneficial EPA and DHA is inefficient and requires considerable metabolic effort.
Serious Long-Term Health Implications
The doctor warned that chronic low levels of omega-3 are not a minor issue. "Long-term low omega-3 levels have been linked to higher inflammation, heart disease risk, mood problems, possibly faster brain ageing and even poorer pregnancy outcomes," he stated.
His clear recommendation is for fish-eaters to aim for two portions of oily fish per week, while those who do not should consider a high-quality, algae-based omega-3 supplement. He concluded with a powerful reframing of the nutrient's importance: "Think of omega-3s as brain nutrition, not just a wellness trend."
This advice comes as a timely reminder during a period when busy, demanding lifestyles often lead to nutritional compromises, making targeted supplementation a practical strategy for maintaining essential health foundations.
