Anchovy

Anchovy refers to small forage fish of the family Engraulidae, primarily harvested from temperate and tropical oceans. The most commercially available species is Engraulis encrasicolus (European anchovy) and Engraulis ringens (Peruvian anchovy). Anchovies are sold fresh, canned in salt or oil, as pastes, or as dried fillets. They are a traditional ingredient in Mediterranean, East Asian, and Southeast Asian cuisines, and are widely used as a umami flavoring base in sauces, dressings, and condiments.

Anchovy is calorie-dense (approximately 175–210 kcal per 100g canned in oil, depending on drain state) and provides approximately 29g protein per 100g. The fatty acid profile is dominated by omega-3 polyunsaturated fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Canned anchovies are typically preserved in salt, making sodium content high—commonly 1,500–3,700 mg per 100g depending on preparation and whether the product is drained and rinsed. Anchovies contain a naturally elevated histamine content due to bacterial decarboxylation of histidine during storage and fermentation, which may trigger reactions in sensitive individuals. When bones are consumed whole, anchovies can provide a meaningful amount of calcium.

Histamine and Sensitivity

Anchovy is a high-histamine food because of its curing, salting, and storage processes. Individuals with histamine intolerance—a condition involving impaired histamine metabolism—may experience flushing, headaches, gastrointestinal upset, or respiratory symptoms after consumption. Histamine levels increase over time in stored fish and cured products. Freshly caught anchovies contain lower histamine than aged or fermented varieties, but commercial preparations are typically aged or salt-cured and should be avoided by those following a low-histamine diet.

Sodium and Blood Pressure

Canned anchovies preserved in salt contain high sodium levels, typically ranging from 1,500 to 3,700 mg per 100g depending on the product and preparation method. A typical 2–3 anchovy portion (approximately 10 g) can deliver 150–370 mg sodium. For individuals managing hypertension or following sodium-restricted diets, anchovy consumption should be limited; rinsing anchovies under cold water before use can reduce sodium content by approximately 30–40%. The American Heart Association recommends no more than 2,300 mg sodium daily. Fresh or frozen anchovies are the lowest-sodium option.

Tolerance and Portion Guidance

Anchovy is well-tolerated in small quantities by most people without fish or shellfish allergy. A typical serving is 2–4 fillets (10–20 g) used as a flavoring or garnish rather than a main protein. Those with fish allergy should avoid entirely. Individuals with gout should consume moderately, as anchovies contain purine compounds (approximately 240–320 mg per 100g per published food composition data), which elevate uric acid when consumed in quantity. Anchovies are considered a low-mercury fish and are generally regarded as a safe choice for pregnant individuals; consult a clinician or midwife for personalised dietary guidance during pregnancy. Persons with sulfite sensitivity should verify that canned varieties do not contain sulfite preservatives.
