Anchovies
Small, oily, and wildly underrated. Anchovies pack more omega-3 per gram than most fish — with the lowest mercury burden of any seafood.
Why It Matters for Longevity
Anchovies deliver 1.5–2.1 g of EPA + DHA per 100g, the active omega-3 forms that reduce systemic inflammation, lower triglycerides, and protect against cardiac arrhythmia. Being small and short-lived, they sit near the bottom of the food chain and bioaccumulate almost no mercury — the primary concern with regular fish consumption. Research confirms they have the lowest contamination among marine species while maintaining the full omega-3 benefit.
Vitamin B12 content is substantial at 0.62 mcg per 28g serving. B12 deficiency accelerates cognitive aging through homocysteine accumulation; anchovies are among the most efficient delivery mechanisms, especially in small daily doses (e.g., on pizza or pasta). Calcium comes as a bonus: canned anchovies with edible bones provide 232 mg per 100g — comparable to dairy.
The Longevity Diet explicitly recommends anchovies as a weekly fish, used on pizzas, in pasta, and as a flavoring in cooked dishes.
How to Use It
Two or three anchovy fillets dissolved in olive oil at the start of a dish add depth without fishiness — they melt into a savory umami base. Classic on pizza, pasta puttanesca, or bagna cauda. Canned in olive oil are shelf-stable and ready to use; packed in salt require rinsing. Eat the bones in canned varieties — that's where the calcium lives.
What to Pair It With
| Ingredient | Why | Tradition |
|---|---|---|
| Olive oil | Fat enhances fat-soluble vitamin absorption; traditional Ligurian/Italian base | Italian |
| Tomatoes | Lycopene absorption improved by oil; umami + acid balance | Italian/Mediterranean |
| Capers | Quercetin in capers complements omega-3 anti-inflammatory action | Italian |
Flavor Profile
Intensely savory and salty with deep umami. Raw or minimally processed: pungent and fishy. Cooked in oil: they dissolve into a rich, nutty background flavor that amplifies other ingredients without announcing themselves. The saltiness demands balance from acid (lemon, tomato) or fat.
The Science
- Small pelagic fish have lowest mercury contamination among marine species (PMID comparison studies)
- 1.5–2.1 g EPA + DHA per 100g — among the highest of any fish
- Calcium: 232 mg per 100g (canned with bones) — comparable to dairy
- Vitamin B12: 0.62 mcg per 28g serving; essential for homocysteine metabolism and cognitive health
Key Nutrients
| Nutrient | Per 100g | Notes |
|---|---|---|
| EPA + DHA | 1.5–2.1 g | Active omega-3 forms; anti-inflammatory, cardioprotective |
| Vitamin B12 | ~2.2 mcg | Bioavailable animal B12; prevents cognitive decline via homocysteine control |
| Calcium | 232 mg | Bioavailable when eating canned anchovies with bones |
| Vitamin D | ~40 IU | Supports calcium absorption; immune modulation |
