Fish stew
Fish stew is a hearty culinary dish consisting of fish or seafood simmered in a flavorful broth, typically combined with vegetables, herbs, and spices to create a comforting, soup-like meal that highlights fresh catches from coastal regions.[1][2] It serves as a versatile staple in many global cuisines, often prepared with economical ingredients like bony or lesser-desired fish to minimize waste while maximizing flavor through slow cooking.[1] Historically, fish stews emerged from practical needs among fishing communities, where unsold or leftover seafood was boiled with available aromatics to produce nourishing meals, a tradition spanning ancient times to modern interpretations.[1][2] For example, the Provençal bouillabaisse originated in Marseille, France, as a frugal fisherman's stew using rockfish, scorpion fish, and scraps simmered in seawater or simple stock, later refined with additions like saffron and fennel in the 19th century.[1][3] Similarly, other variants trace roots to medieval or earlier practices, such as Russia's ukha, documented since the 11th century as a general soup that evolved into a clear fish broth from peasant soups by the 17th century.[3] Key ingredients in fish stews generally include sturdy white fish like cod, haddock, or pollock, along with onions, garlic, tomatoes, potatoes, and liquids such as fish stock, wine, or coconut milk, which impart regional character and texture.[2][1] Variations reflect local availability and tastes: the creamy New England clam chowder from the United States features clams, potatoes, and cream for a thick consistency; Thailand's Tom Yum Talay incorporates shrimp, lemongrass, chilies, and lime for a spicy-sour profile; while Portugal's caldeirada layers mixed fish, shellfish, and tomatoes in a spiced, olive oil-enriched broth.[3] These adaptations underscore fish stew's adaptability, often served with bread to soak up the broth and enjoyed as both everyday fare and festive dishes.[2][3]Overview
Definition
A fish stew is a culinary dish consisting of fish or seafood as the primary protein, cooked slowly in a liquid medium such as broth or stock, often combined with vegetables and seasonings to create a flavorful, hearty preparation.[4][5] This hot, liquid-based meal distinguishes itself from drier cooked fish dishes by its simmering process, which allows flavors to meld in a single pot, typically resulting in a thicker consistency than soup due to evaporation and added thickeners like tomatoes or grains. Central to fish stew are core elements such as fresh, frozen, or preserved fish—ranging from white fish like cod to shellfish—serving as the main component, alongside aromatics including onions, garlic, and herbs that form the flavorful base.[2] These ingredients are simmered together to produce a complete, nutritious one-pot meal that emphasizes simplicity and the natural taste of seafood.[6] The word "stew" originates from the Old French verb estuver, meaning "to bathe in steam" or "to enclose for heating," derived from Vulgar Latin extufare (to emit steam), and by the late 14th century in English, it specifically denoted slow cooking by simmering in liquid within a closed vessel.[7] This etymology underscores the gentle, enclosed cooking method applied to fish-based versions, adapting the general term to highlight seafood-centric preparations across various traditions.Key Characteristics
Fish stew is distinguished by its varied texture and consistency, with the broth ranging from thin and clear to thick and chunky, depending on the incorporation of vegetables, stocks, or thickening agents. The fish components are typically tender and flaky, achieved through gentle poaching or simmering that preserves their delicate structure without overcooking, resulting in pieces that easily break apart in the mouth. Emulsified elements, such as those from fish oils, creams, or repeated pounding of solids into the broth, often contribute to a creamy, velvety body that enhances the overall mouthfeel.[8][9] The flavor profile of fish stew centers on the inherent umami from fresh fish, which provides a savory depth amplified by the natural glutamates in seafood. This umami is balanced by acidity introduced through tomatoes, wine, or citrus, preventing any heaviness and adding brightness to the dish. Herbs like fennel, bay leaves, and thyme, along with spices such as saffron or pepper, layer aromatic complexity, creating a harmonious blend that underscores the freshness central to coastal culinary traditions.[8][9] In terms of serving style, fish stew is commonly presented hot with crusty bread for dipping and absorbing the flavorful broth, or spooned over rice to soak up the liquids and add substance. This format facilitates communal eating in various cultures, where the dish is often shared from a large platter, encouraging social interaction during meals.[8][10]History
Origins
The origins of fish stew trace back to ancient Mediterranean civilizations, where archaeological evidence from Bronze Age sites indicates early practices of processing fish into preserved forms that likely formed the basis for stew-like preparations. Excavations at Akrotiri on the island of Thera (modern Santorini), dating to around 2000 BCE, have revealed remains of processed fish products, reflecting early preservation techniques in Minoan cuisine.[11] While specific recipes are scarce, textual and artifactual evidence suggests that Minoan dishes incorporated fish preparations alongside stews, often enhanced with local herbs and oils, as part of daily coastal diets.[12] By the Roman era, these traditions evolved into more documented culinary forms, as seen in the 1st-century CE cookbook De re coquinaria attributed to Apicius. This text describes several fish-based dishes involving garum, a fermented fish sauce central to Roman cooking, such as boiled fish seasoned with pepper, liquamen (garum), cumin, passum (raisin wine), vinegar, defrutum (reduced grape must), and oenogarum (a wine-garum sauce).[13] Another recipe prepares boiled fish in a pan with similar ingredients, including oil, underscoring garum's role in creating flavorful broths that simmered fish into stew-like consistencies.[14] These Roman adaptations built on earlier Mediterranean practices, emphasizing garum as a key umami enhancer derived from fermented fish entrails.[15] Indigenous influences contributed independently to early fish stew traditions in other regions. Among pre-colonial coastal Native American tribes, such as the Anishinabe (Ojibwe), simple broths were prepared by boiling fish with corn and wild rice until thickened, forming nutrient-dense stews that sustained communities reliant on freshwater and marine resources.[16] In the Pacific Northwest, tribes like the Suquamish heavily incorporated salmon into one-pot stews.[17] Similarly, Polynesian societies developed coconut-based fish preparations around 1000 CE, coinciding with their oceanic expansions; traditional dishes involved cooking reef fish in coconut milk, creating creamy stews sweetened naturally and served as staples in island feasts.[18][19] A pivotal early milestone occurred in the 16th century with the Columbian Exchange, which introduced New World ingredients like tomatoes to European cuisines, fundamentally transforming existing fish stew recipes by adding acidity and richness to broths.[20] Spanish and Portuguese explorers brought tomatoes back from the Americas, where they were integrated into coastal dishes, enhancing Mediterranean and Atlantic variants with vibrant, tangy profiles that persist in evolved forms. This exchange marked a shift from herb- and garum-dominated preparations to more diverse, globally influenced iterations.[21]Historical Development
During the colonial era, fish stews in the Americas underwent significant adaptations between the 17th and 19th centuries, incorporating New World ingredients such as potatoes to enhance sustenance and texture in dishes like chowders. Originating from French coastal traditions of layered cauldrons (chaudieres), these stews evolved in New England colonies, where early recipes layered fish, bacon, onions, and potatoes in a flour-thickened broth, as seen in Lydia Maria Child's 1830 The Frugal Housewife, which reflects widespread popularity with over 35 printings by 1850.[22] Potatoes, a staple crop by the 18th century, became integral to these one-pot meals, providing bulk amid limited resources.[23] British colonial migrations from Caribbean islands like Barbados to regions such as South Carolina further influenced seafood stews, blending European techniques with local flavors in dishes like she-crab soup and gumbo precursors, where enslaved cooks adapted British stew methods to abundant coastal seafood.[24] In the 20th century, industrialization transformed fish stews through advancements in preservation, particularly the canning of sardines starting in the late 19th century, which enabled year-round access to preserved fish for stews in Europe and beyond. Portuguese factories, such as those adopting can-sealing machines by the early 1900s, shifted to boiling sardines in spiced saltwater, producing durable products that supported export and home cooking of hearty, preserved stews by the 1926 expansion of operations like Nero's.[25] This innovation complemented traditional recipes, allowing dishes like fisherman's sardine stew to incorporate canned fish for convenience without fresh sourcing. Post-World War II, the end of rationing in countries like the UK in 1954 contributed to a surge in seafood consumption in Europe, as abundance replaced wartime scarcity and promoted affordable, nutrient-rich stews amid economic recovery and global trade resumption.[26] Fish, already valued during rationing for its protein efficiency, saw heightened popularity in home and tavern preparations, reflecting a broader shift to diverse, accessible cuisines.[27] Building on ancient Mediterranean and European origins, 21st-century developments emphasize sustainability in fish stews, driven by movements promoting eco-friendly sourcing to combat overfishing and habitat loss. Certifications like the Marine Stewardship Council (MSC) blue label, adopted widely since the 2000s, guide consumers toward responsibly caught seafood, ensuring low-emission proteins for dishes while minimizing environmental impact—71% of buyers prioritize such independent verification.[28] Concurrently, fusion versions emerged in globalized kitchens from the 1990s onward, blending traditions like Mediterranean-Asian fish stews with ingredients such as coconut milk and yuzu for innovative profiles that prioritize complementary flavors over novelty.[29] These adaptations reflect heightened awareness of ethical sourcing and cultural exchange in modern culinary practices.[30]Ingredients
Core Components
The core components of a fish stew revolve around a selection of fresh seafood proteins, flavorful liquids to form the broth, and foundational aromatics that provide depth and structure. These elements ensure the dish remains hearty yet balanced, with the proteins serving as the centerpiece while the liquids and aromatics create a cohesive base.[31][32] The primary protein typically consists of firm white fish fillets such as cod, haddock, halibut, or sea bass, which hold their texture during cooking and contribute a mild, flaky quality to the stew. Shellfish like mussels, clams, or shrimp are often incorporated for added brininess and variety, enhancing the seafood profile without overpowering the dish. A standard quantity for these proteins is 1 to 2 pounds total for four servings, allowing the stew to remain substantial yet not overwhelming.[31][33][32] Base liquids form the stew's broth, starting with fish stock made from simmering fish bones, heads, and trimmings with aromatics to extract a rich, oceanic essence that amplifies the seafood flavors. Vegetable or chicken broth serves as a milder alternative when fish stock is unavailable, while acids such as dry white wine or fresh lemon juice are added for brightness and to cut through the richness, typically in amounts of 1/2 to 1 cup of wine or the juice of one lemon per four servings. Tomatoes, either fresh or canned, are commonly included to provide a subtle acidity and body to the liquid base.[34][33][32] Aromatics and thickeners establish the stew's foundational flavor and consistency, with common aromatics such as onions, often with celery and/or carrots—roughly 1 medium onion, 1-2 celery stalks, and/or 1 carrot, diced—sautéed to release sweetness and depth. Garlic and fresh herbs like parsley or thyme further enhance the profile. For body, potatoes (about 2-3 medium, cubed) or a simple roux made from flour and fat are optional additions that absorb flavors and provide substance without dominating the seafood.[35][36][31]Regional Adaptations
In tropical regions, particularly Southeast Asia, fish stews often incorporate coconut milk as a primary liquid base, providing a rich, creamy texture that contrasts with the wine typically used in European versions for acidity and depth. This adaptation leverages locally abundant coconuts to enhance flavor without relying on fermented ingredients, resulting in a milder, aromatic broth infused with ginger and greens.[37][38] In Latin American adaptations, starchy staples like plantains or yuca frequently substitute for potatoes, adding sweetness and a denser consistency suited to the region's tropical agriculture and coastal availability. These root vegetables absorb flavors from the fish and spices while contributing nutritional heft, making the stew more filling in humid climates.[39][40] In Northern Europe, herbs such as dill are commonly used to complement fresh fish and vegetables, often in creamy stews paired with root vegetables like potatoes and carrots.[41][42][43] Allergen considerations lead to dairy-free formulations in Mediterranean regions, where olive oil serves as the key fat for emulsifying the broth and imparting fruity notes, accommodating lactose intolerance while aligning with dietary traditions. This differs from New England styles, which traditionally rely on cream for a velvety richness, though adaptations may reduce dairy for broader accessibility.[32][44][45]Preparation
Basic Techniques
Preparing a standard fish stew begins with mise en place to ensure efficient cooking and optimal texture. Start by chopping vegetables such as onions, garlic, celery, and carrots into uniform pieces for even cooking, typically yielding about 1 cup of onions and ½ cup of celery for a basic batch. Prep the fish by selecting firm white varieties like cod or halibut, patting them dry, removing any bones or skin, and cutting into 1- to 2-inch chunks to promote quick, even cooking without falling apart. This preparation stage usually takes 10-15 minutes and sets the foundation for a stew that simmers gently to avoid overcooking the delicate fish protein.[31][35] The core cooking method involves sautéing aromatics followed by simmering, which builds flavor layers while keeping the process straightforward. Heat 2-3 tablespoons of olive oil or butter in a large, heavy-bottomed pot or Dutch oven over medium heat, then add the chopped onions, celery, and garlic, sautéing for 4-5 minutes until softened and fragrant but not browned. Stir in tomato paste or diced tomatoes if using, cooking for another 1-2 minutes to deepen the base, then deglaze the pot with ½ to 1 cup of dry white wine, clam juice, or broth, scraping up any browned bits for added richness. Bring the mixture to a simmer, add potatoes or other sturdy vegetables if desired, and cook covered for 10-15 minutes until tender. Finally, nestle the fish chunks into the broth and simmer on low heat for 5-10 minutes more, or until the fish flakes easily with a fork, ensuring the total simmering time remains 20-30 minutes to prevent toughness.[31][35][36] For scaling servings from 2 to 6 people, adjust ingredients proportionally—such as doubling the fish to 3 pounds and liquids to 4-6 cups for larger groups—while maintaining low-heat simmering to preserve the fish's tenderness and moisture. This approach ensures the stew remains balanced, with fish added last to cook gently in the hot broth without direct high heat. Advanced flavor enhancements, like specialized roux or infusions, can build on these basics for more complexity.[46][35]Advanced Methods
In advanced preparations of fish stew, emulsification techniques are employed to achieve a luxurious, velvety texture that binds the broth and enhances mouthfeel. This process involves slowly incorporating fats such as butter or aioli into the simmering liquid while whisking vigorously to create a stable emulsion, preventing separation and yielding a creamy consistency without curdling the proteins.[8] A classic example is the Provençal rouille, an emulsified sauce made by gradually adding olive oil to a base of garlic, chili peppers, egg yolk, and soaked bread or potato, which is then floated on the stew or spread on croutons for serving.[47] For partial pureeing, an immersion blender can be used directly in the pot to blend a portion of the vegetables and broth while leaving chunks of fish and other solids intact, resulting in a textured yet cohesive stew that maintains visual appeal and varied bite.[48] Infusion techniques further elevate flavor depth in fish stews by extracting complex aromas from ingredients through controlled heat and time. Saffron threads are commonly steeped in warm white wine or stock for 15-20 minutes prior to incorporation, allowing the spice's volatile compounds to infuse the liquid with earthy, floral notes that permeate the entire dish without overpowering the seafood.[49] Similarly, seafood shells—such as those from shrimp, lobster, or crab—are roasted briefly at 400°F (204°C) to caramelize proteins, then simmered in water or wine for 30-45 minutes to release umami-rich glutamates and minerals into the broth base, which is strained before adding fresh fish to avoid grit.[50] Adaptations using pressure cookers accelerate this infusion; for instance, shells and aromatics can be cooked under high pressure for 10 minutes, followed by a natural release, condensing flavors in a fraction of traditional simmering time while preserving tenderness in delicate fish added post-pressurization.[51] Preservation methods for fish stew focus on techniques that retain nutritional integrity and sensory qualities during storage. For canning, the cooled stew is packed into pint jars with 1-inch headspace, then pressure-processed at 10-11 psi for 100 minutes (fresh) or 110 minutes (smoked variants) to ensure destruction of Clostridium botulinum spores, enabling shelf-stable storage at room temperature for up to a year.[52] Freezing involves portioning the stew into airtight containers with minimal air exposure, and storing at 0°F (-18°C) or below for 3-6 months; to maintain freshness upon thawing, avoid refreezing and reheat gently to prevent texture degradation from ice crystal formation.[53]Regional Variations
European Varieties
One of the most iconic European fish stews is bouillabaisse, originating from the Provençal region of France, particularly the port city of Marseille, where it began as a simple fisherman's dish utilizing unsold or less desirable rockfish.[54] Traditionally prepared with scorpionfish (rascasse) as a primary ingredient, along with other Mediterranean varieties such as conger eel, whiting, and mullet, the stew features a flavorful broth enriched by tomatoes, saffron, garlic, onions, fennel, and olive oil.[8] The dish is typically served in two parts: the aromatic broth first, accompanied by croutons and rouille—a spicy, garlicky mayonnaise made with saffron, cayenne, and egg yolk—followed by the poached fish.[8] This preparation highlights the stew's rustic roots while adhering to a strict charter established in the 1980s to preserve its authenticity using local catches.[54] In Italy, cacciucco represents a robust Tuscan tradition, hailing from the coastal city of Livorno, where it evolved from fishermen's practices of combining unsellable seafood into a hearty one-pot meal.[55] The stew incorporates a diverse mix of seafood, prominently featuring cuttlefish, octopus, squid, eel, mussels, clams, and firm-fleshed fish like monkfish or red gurnard, all simmered in a tomato-based broth infused with red or white wine, garlic, onions, celery, fennel, chili, and sage for depth.[56][57] Preparation involves staged cooking to respect varying textures: tougher cephalopods like cuttlefish and octopus are braised first in the wine-tomato mixture for tenderness, followed by shellfish and fish added toward the end to avoid overcooking.[55] Often finished with a drizzle of olive oil and served over grilled bread rubbed with garlic, cacciucco embodies Livorno's maritime heritage and is traditionally enjoyed with a rustic red wine.[58] Portugal's caldeirada offers a layered approach to fish stew, rooted in the coastal traditions of regions like Peniche and influenced by the 15th-century Age of Discoveries, when Portuguese explorers adapted onboard cooking methods using available catches during long voyages.[59] This versatile dish assembles ingredients in alternating layers—starting with sliced onions, bell peppers (red and green), and tomatoes at the bottom of a pot, followed by thick potato slices, then mixed fish such as monkfish, conger eel, or sardines, and topped with more vegetables, garlic, bay leaves, chili, and a generous pour of olive oil and white wine.[59] The slow simmering allows flavors to meld, with the potatoes absorbing the broth's essence, resulting in a colorful, aromatic stew that reflects the era's exploratory spirit and resourcefulness at sea.[59] Regional variations may include shellfish or coriander, but the layered method remains central to its identity as a communal, seafaring staple.[59]North American Varieties
North American fish stews reflect the fusion of European immigrant traditions with local seafood abundance, particularly along the Atlantic and Pacific coasts. These dishes emerged from colonial settlements and later waves of migration, adapting Old World recipes to New World ingredients like haddock, clams, and Dungeness crab.[60] Cioppino, a hallmark of San Francisco's culinary scene, originated in the late 19th century among Italian fishermen, primarily from Genoa, who settled in the city's North Beach neighborhood. Created between 1850 and 1880 at what was then Meiggs' Wharf (now Fisherman's Wharf), the stew arose from the practical need to use unsold or leftover catch at day's end, with fishermen contributing ("chipping in") their portions. This Italian-American dish features a tomato-based broth enriched with garlic, white wine, herbs, and chili peppers, incorporating local seafood such as Dungeness crab, clams, shrimp, mussels, and squid. The earliest documented reference appears in a 1901 San Francisco Call article, predating the 1906 earthquake's impact on the fishing community.[61] New England fish chowder, a creamy staple of the region's maritime heritage, traces its roots to 18th-century British settlers who brought stew-making techniques from Europe. The first printed recipe appeared in the Boston Evening Post on September 23, 1751, describing a layered preparation of fish, salt pork, onions, and ship's biscuits simmered in water. By the 19th century, it evolved to include a milk or cream base for richness, with haddock as the primary fish due to its availability and flaky texture, alongside diced potatoes for substance, celery, and onions. This adaptation distinguished it from thinner European broths, emphasizing local bounty while honoring settler traditions.[60][62][63] Manhattan clam chowder, a tomato-based counterpart, developed in the mid-19th century amid rising tomato popularity and influences from Italian and Portuguese immigrants in New York and Rhode Island. Initially known as Coney Island or Fulton Market clam chowder in the 1890s, it substituted tomatoes for cream to create a lighter, reddish broth with clams, potatoes, carrots, celery, and onions. Early recipes, such as those in Alessandro Filippini's 1889 cookbook and Charles Ranhofer's 1894 guide, highlight this vegetable-forward style. From its inception, it sparked debate as an illegitimate variation on traditional chowder, with critics like James Beard dismissing it as "vegetable soup with clams"; in 1939, a Maine legislator even proposed banning tomatoes in chowder to preserve New England purity. By the 1930s, the name "Manhattan clam chowder" solidified, though the controversy endures.[64][65]Asian and Oceanic Varieties
In Asian and Oceanic cuisines, fish stews often incorporate tropical flavors, fresh seafood, and aromatic spices, reflecting the region's diverse maritime influences and abundant local ingredients. These preparations typically feature lighter, spice-forward broths served with rice, distinguishing them from heavier Western variants. Sinigang, a staple Filipino sour soup, traces its origins to pre-colonial times, predating Spanish arrival in the 16th century, and remains an everyday comfort dish in households across the Philippines.[66] The broth achieves its signature tang through tamarind, a native souring agent, simmered with fish such as bangus (milkfish), alongside vegetables like eggplant, okra, string beans, and kangkong (water spinach).[67] This simple yet versatile preparation highlights indigenous souring techniques using unripe fruits, making it a nutritious, affordable meal integral to Filipino daily life.[68] Tom jued, a light Thai clear soup, embodies the simplicity of home cooking with its herbal, non-spicy profile, often prepared as a weekly family staple using pork or chicken broth as the base.[69] In seafood variations, prawns take center stage, combined with glass noodles (woon sen), tofu, and vegetables like Chinese cabbage, mushrooms, and carrots, all gently simmered to preserve delicate flavors without overpowering heat.[70] This traditional dish underscores Thai culinary restraint, prioritizing fresh ingredients and subtle seasoning for a comforting, low-calorie broth typically enjoyed with jasmine rice.[69] Fish head curry represents a 20th-century fusion in Singapore and Malaysia, invented in 1949 by Indian immigrant M. J. Gomez, a Malayalee from Kerala, who adapted South Indian curry techniques to appeal to Chinese customers fond of fish heads.[71] The dish gained popularity after Chinese chef Hoong Ah Kong refined the recipe in 1951 at his restaurant, blending Indian spices with local elements; by the 1970s, it had become a national icon served in claypots.[71] Key ingredients include a whole red snapper head stewed in a thick, spicy coconut milk-based curry paste of chilies, turmeric, tamarind, and curry powder, accompanied by vegetables such as okra, eggplant, long beans, and tomatoes.[72] This hearty preparation, emphasizing the tender cheeks and gelatinous texture of the fish head, exemplifies Peranakan and multicultural influences in Southeast Asian street food culture.[72]Nutrition and Cultural Aspects
Nutritional Profile
Fish stew offers a nutrient-dense meal, primarily due to its base of seafood and vegetables, which contribute to a balanced intake of essential macronutrients and micronutrients. A typical serving (approximately 250-300 grams) provides around 100-300 calories for lean, broth-based versions, up to 500 calories for richer preparations incorporating olive oil or fatty fish like salmon.[73][74][75] This variability arises from recipes that range from lean, broth-based versions to richer ones incorporating olive oil or fatty fish like salmon. However, considerations such as mercury content in certain fish (e.g., larger predatory species) should be noted for safe consumption, particularly for vulnerable groups.[76] In terms of macronutrients, fish stew is notably high in protein, delivering 19-47 grams per serving from the fish component, which supports muscle repair and satiety. Carbohydrates are moderate, typically 7-23 grams, mainly from vegetables like potatoes, tomatoes, or onions, while fats range from 1-15 grams, often including healthy monounsaturated fats from olive oil or the fish itself. These levels position fish stew as a protein-focused dish with lower carbohydrate content compared to grain-heavy meals.[73][74][75] Micronutrients in fish stew are abundant, particularly omega-3 fatty acids from the seafood, with servings providing 0.1-2 grams of combined EPA and DHA, beneficial for cardiovascular health and reducing inflammation. Vitamins A and C are contributed by tomatoes, peppers, and herbs, offering antioxidant support, while the fish supplies selenium (a key antioxidant mineral, up to 34 mcg per serving). Other notable elements include vitamin D (around 0.3-1 mcg). Iodine content varies by fish type, typically 50-200 mcg per serving.[77][78][79][80][81] A representative caloric breakdown for a standard fish stew serving (e.g., 300 calories total) allocates approximately 40% to protein (from fish), 30% to fats (including omega-3 sources), and 30% to carbohydrates from vegetables, highlighting its role as a lean yet satisfying option. This distribution can shift with ingredient choices, such as using lean white fish versus oily varieties.[82][74]| Nutrient Category | Approximate Contribution per Serving | Key Sources |
|---|---|---|
| Protein | 20-30g (40% of calories) | Fish |
| Fats | 5-10g (30% of calories, incl. omega-3) | Fish and oil |
| Carbohydrates | 10-20g (30% of calories) | Vegetables |
