⚠️ But Be Careful: When Lemon + Tuna Might Be a Problem
❗ Vitamin C vs. Iron in Tuna
- Lemon enhances non-heme iron absorption (from plant foods)
- Tuna contains heme iron, which doesn’t benefit as much from vitamin C
- The acidic environment may slightly degrade sensitive nutrients like B12 if stored too long in lemon juice
✅ Tip: Add lemon right before eating — not hours in advance.
❗ Mercury in Tuna + Acidic Marinade
- Tuna can contain moderate mercury (especially albacore or bigeye)
- Soaking tuna in lemon for long periods may affect mineral balance and alter taste
- Acid can increase oxidation of fats if exposed to air too long
✅ Use lemon as a fresh finish, not as a long soak.
❗ Canned Tuna + Lemon Juice? Watch the Sodium
- Many canned tunas are already high in sodium
- Adding lemon is fine — but avoid salty sauces or dressings on top
✅ Balance flavors with herbs (dill, parsley) instead of extra salt.
