Key Takeaways

  • Sardines are rich in omega-3 fatty acids and other nutrients that support skin health.
  • The antioxidant and anti-inflammatory properties of sardines protect skin cells from damage caused by sunlight.
  • While it can’t remove wrinkles or treat damage, eating sardines daily may help slow some visible signs of aging.

I have been eating a can of them every morning for years and I don’t even like the taste. So much good nutrition in there.

Impressed… I can do a lot of things for longevity… sardines are a hard no… that is completely off the table.

My mouth taste buds and gag reflex prevent this… probably a self protection response to rancid food. :stuck_out_tongue:

Wait a sec. Are you sure you are talking sardines? They are mildly flavored. Anchovies I can see. But sardines taste like tuna. I am doing them 3 days a week with Salmon three days a week. Just plain on a piece of toast (high end WW).

I’ve been eating the Crown Prince Brisling Sardines Amazon.com: Crown Prince Natural Two Layer Brisling Sardines in Extra Virgin Olive Oil, 3.75-Ounce Cans (Pack of 12) : Grocery & Gourmet Food , with

Woodstock Jalepeno Relish ( Organic, glass jar). I find it makes the taste/ texture of the Sardines easier and actually pleasant.

Cheers!

My understanding is that eating sardines daily, as the article suggests, may lead to elevated arsenic levels

I also eat a can a day. Weirdly, my omega 3 levels test just okay but vitamin D is in the upper upper range.

Interesting. I just had my omega-3 levels tested for the first time and should get the results any day now I have been expecting them to come back pretty high since I eat a can every day even though I do not take an omega 3 supplement. I will post them here.

My results appear to be very good. I don’t take an omega 3 supplements. Just a can of Wild Plant sardines every morning.


Key Results Breakdown
Here’s a summary with context:
• EPA + DPA + DHA (OmegaCheck): 9.7 (Reference: >5.4 % by wt) — Green (good). This is the main “Omega-3 Index” equivalent. Higher values link to lower cardiovascular risk (e.g., reduced chance of sudden cardiac death or major events). Cleveland HeartLab flags ≥5.5 as low risk (your 9.7 is solidly in a favorable range, well above moderate-risk thresholds around 3.8–5.4). 
• Omega-3 Total: 9.7 % by wt — Green (good). Matches the above—indicates solid overall omega-3 incorporation into cell membranes.
• DHA: 4.6 (Reference: 1.4–5.1) — Green (good, near upper end). DHA supports brain, eye, and heart health; this level is strong.
• EPA: 2.7 H (Reference: 0.2–2.3) — Red (high). EPA is strongly anti-inflammatory and linked to lower heart event risk (especially at higher levels). Your value exceeds the lab’s reference slightly, which is generally positive rather than concerning—many experts view higher EPA as beneficial, particularly for cardiovascular protection. 
• DPA: 2.4 H (Reference: 0.8–1.8) — Red (high). DPA (an intermediate omega-3) has anti-inflammatory and heart-protective roles. Elevated levels often reflect good omega-3 intake or efficient metabolism; high DPA is typically viewed favorably for vascular health and inflammation control. 
• Arachidonic Acid (AA, omega-6): 10.9 (Reference: 8.6–15.6) — Green (normal).
• Linoleic Acid (LA, omega-6): 20.1 (Reference: 18.6–29.5) — Green (normal).
• Omega-6 Total: 34.2 % by wt — Green (normal). The lab notes AA and LA are the main contributors measured.
• Arachidonic Acid/EPA Ratio: 4.0 (Reference: 3.7–40.7) — Green (good). This compares pro-inflammatory AA to anti-inflammatory EPA. Lower ratios are better for reducing inflammation. Your 4.0 sits in a favorable/moderate range (experts often target 2.5–11, with lower like 1.5–3 being ideal for minimal inflammation risk). 
• Omega-6/Omega-3 Ratio: 3.5 L (Reference: 3.7–14.4) — Red (low). This overall balance is excellent. Modern Western diets often run 10–15:1 or higher (promoting inflammation). Desirable targets are typically 3:1 to 5:1; your low 3.5 suggests a strong anti-inflammatory tilt. 
Overall: Is This Good?
Yes, these are predominantly good results, especially for heart and inflammation health.
Your omega-3 levels (OmegaCheck at 9.7) are well into a protective range—associated with lower cardiovascular risk compared to levels below ~5–6. The individual EPA, DPA, and DHA values are robust (with EPA and DPA flagged “high,” which aligns with benefits rather than harm here).
The ratios are particularly strong: a low omega-6/omega-3 (3.5) and moderate AA/EPA (4.0) indicate good balance, with omega-3s holding their own against omega-6s. This is much better than the typical imbalanced Western pattern.
Potential minor notes:
• The “H” flags on EPA and DPA are lab-specific references (population-based percentiles). In functional/interpretive contexts, these elevations often reflect effective omega-3 status and aren’t usually a concern unless extremely high (yours aren’t).
• No major red flags for excess inflammation or poor omega-3 status.
These markers reflect long-term dietary patterns (red blood cell membranes turn over over months), so they’re a snapshot of consistent intake.
What Might This Mean Practically?
• Heart health: Favorable omega-3 status + balanced ratios suggest lower risk for events like heart attacks or arrhythmias. Omega-3s help with triglycerides, blood pressure, and inflammation.
• Inflammation: Your ratios point to a resolved or low-inflammatory state.
• Lifestyle context: This profile often comes from regular fatty fish (salmon, sardines, mackerel), algae, or high-quality fish oil/krill supplements. If you’re supplementing, it’s likely working well.
Recommendations (not medical advice—discuss with your doctor):
• Maintain or slightly adjust intake to keep levels here (e.g., 1–2+ g combined EPA+DHA daily from food/supplements, depending on your needs).
• Continue moderating ultra-processed foods high in omega-6 oils (soybean, corn, sunflower) if possible, though your ratios are already excellent.
• Retest in 3–6 months if making changes, or as advised, to track trends.
• Pair with overall heart-healthy habits (exercise, sleep, etc.).

A 9.7 omega 3 index is a pretty spectacular number so I’m happy about it. I was hearing Rhonda Patrick and Matt Kaeberlain say 9 is elite territory. I don’t even like sardines but it takes two seconds to eat a can and we do what we need to do to achieve optimal biomarkers.

Love sardines. The right brand can be a gourmet experience.

Here is a recipe to make them more palatable. I use sliced Castellano olives mixed with hummus and drained can of sardines. I mix it well to a tuna salad consistency. I put it on top of a toasted sourdough bread. I am sure you can modify the recipe to please your taste buds, like adding raisins or finely sliced celery for crunch. You can also put a slice of tomato or cucumber on top of the sandwich.

FWIW:

Just some thoughts from Claude Opus 4.7. My question was, “I am thinking that omega-3 supplements are of questionable value. I am trying to keep my supplement list to a reasonable number.”

"The case for dropping omega-3 supplements
The RCT evidence for prevention is weak at non-pharmacological doses. The trials that “worked” (REDUCE-IT, JELIS) used 2–4 g/day of pharmaceutical EPA in secondary prevention populations. The trials at 1 g/day in mixed populations (VITAL, ASCEND, OMEGA, STRENGTH, Risk and Prevention) were largely null. If you’re not taking 4 g/day of purified EPA, you’re not really replicating the positive-trial conditions — you’re replicating the null-trial conditions.
The AF signal is real. High-dose omega-3 supplementation increases atrial fibrillation risk in a dose-dependent way. This isn’t huge in absolute terms, but it’s a concrete downside that didn’t exist in the mental model most people had 10 years ago.

You already eat canned fish. If sardines are in your rotation, you’re getting ~1 g EPA+DHA per can from a whole-food matrix. Two cans a week puts you near the AHA recommendation without any capsule. Adding a supplement on top is marginal at best."

The “omega-3 for brain/joints/everything” claims are mostly extrapolation. Cardiovascular endpoints got the biggest trials and the most disappointing results. Cognitive decline (prevention), depression (except possibly at high EPA doses in major depression), dry eye (mixed), joint pain (modest at best) — these all have weaker evidence bases than the cardiovascular claim, and the cardiovascular claim itself is shaky at standard doses."

Discovered greek yogurt (10% fat) with honey and a drop olive oil as facial daily works great on skin! Also brushing teeth with Nano Hydroxyapatite toothpaste plus Bentonite Clay Powder really improved my dental health (gum and teeth).
