Can You Eat Healthy and Still Have Nutritional Imbalances?

5 min read

Yes. And it's more common than the phrase "eating healthy" would suggest.

What "healthy eating" usually means — and what it doesn't measure

"Eating healthy" is typically shorthand for avoiding processed food, eating more vegetables, and keeping added sugar low. These are genuinely good habits. None of them, by themselves, guarantee balance between specific nutrients — particularly the omega-6 to omega-3 ratio, which depends on the type of fat in a diet, not just its overall cleanliness.

A diet can be clean and still skewed

Lean meats, whole grains, and plant-based cooking oils are all reasonable choices by conventional standards — and all of them tend to be higher in omega-6 relative to omega-3. A 2025 global study, drawing on nearly 600,000 blood samples, found this pattern holds broadly: modern diets have shifted toward overconsumption of omega-6-rich vegetable oils and processed foods, alongside comparatively low omega-3 intake, even in populations that would generally be considered health-conscious.

The study's authors made a specific point of noting that even among their study cohort — people who opted into home health testing, plausibly a more health-conscious subset of the population — total omega-6 to omega-3 ratios remained above the levels associated with optimal balance. Their conclusion: even health-conscious individuals may not achieve optimal fatty acid balance without targeted dietary intervention.

Why this gets missed

It's entirely possible to eat a diet most nutritionists would call healthy and still carry a ratio far more skewed than what the body evolved to handle — not because of a flaw in trying to eat well, but because "healthy eating," as a general category, was never designed to measure this specific balance.

The only way to know which category you're in

A simple at-home test shows your actual ratio directly, rather than relying on how clean your plate looks. If this is the second or third time you're reading a version of this point on this blog, that's intentional: it's the single most common misunderstanding in wellness, worth restating from a few different angles because it's the one most people never think to question.
