10 Recipes for a Heart-Healthy Diet — The Food, the Science, and the Flavour

By BiteBrightly 28 July 2026: This post might contain affiliate links.

Cardiovascular disease remains the leading cause of death globally — and diet is one of the most powerful and most modifiable risk factors available. The 2026 American Heart Association Scientific Statement on dietary guidance for cardiovascular health confirmed that poor diet quality is strongly associated with elevated cardiovascular disease morbidity and mortality risk, and that a heart-healthy dietary pattern — built around vegetables, fruits, whole grains, healthy protein sources, and unsaturated fats — meaningfully reduces that risk.

This guide presents 10 genuinely delicious recipes built around the foods and dietary patterns with the strongest cardiovascular health evidence — primarily the Mediterranean dietary pattern, which the landmark PREDIMED randomised controlled trial found was associated with a 30% lower risk of major cardiovascular events (heart attack, stroke, or cardiovascular death) compared to a low-fat control diet.

These recipes are not bland medical food. They are full-flavoured, satisfying meals built around olive oil, oily fish, legumes, whole grains, nuts, and an abundance of vegetables — the actual foods the evidence supports. Every recipe includes the specific cardiovascular mechanism it addresses and uses confirmed heart-healthy cooking methods.

If you have been diagnosed with heart disease, are taking cardiac medication, or have had a cardiovascular event, please follow the dietary guidance of your cardiologist or a registered dietitian — this guide is for general heart-healthy eating, not for the management of diagnosed cardiovascular conditions.

Key Takeaways

• The landmark PREDIMED randomised controlled trial found that a Mediterranean diet enriched with extra-virgin olive oil or nuts was associated with a 30% lower risk of major cardiovascular events compared to a low-fat control diet — one of the strongest dietary intervention findings in cardiovascular research

• The 2026 American Heart Association Scientific Statement confirmed that a heart-healthy dietary pattern includes: plenty of vegetables and fruits, whole grains over refined grains, healthy protein sources, unsaturated fats over saturated fat, and minimal processed food, added sugar, and salt

• A June 2025 review in Cardiovascular Research confirmed that plant-based dietary patterns rich in minimally processed foods reduce CVD risk, while patterns rich in ultra-processed foods, meat, salt, sugar, and saturated fat increase risk — with the Mediterranean, DASH, and vegetarian diets all showing CVD risk reduction

• Omega-3 fatty acids from oily fish (EPA and DHA) reduce triglycerides, reduce inflammation, and improve heart rhythm — the American Heart Association recommends at least two servings of fatty fish per week for cardiovascular health

• Soluble fibre from oats, legumes, and fruits binds cholesterol in the digestive tract and prevents its reabsorption — reducing LDL cholesterol through a direct, well-established mechanism; the 10g+ of soluble fibre per day consistently associated with LDL reduction is achievable from whole food sources

• Extra-virgin olive oil is the primary fat of the Mediterranean diet — its monounsaturated fats lower LDL while maintaining HDL cholesterol, and its oleocanthal provides anti-inflammatory COX enzyme inhibition; the PREDIMED trial used approximately 4 tablespoons (50ml) of extra-virgin olive oil daily in the intervention group

The Heart-Healthy Dietary Pattern — What the Evidence Supports

Before the recipes, the nutritional framework they are built around — because understanding why these ingredients are chosen makes the dietary changes easier to maintain long-term.

Olive oil (primary fat): Monounsaturated oleic acid lowers LDL without reducing HDL — the most favourable lipid profile change available from a dietary fat. Extra-virgin olive oil additionally provides oleocanthal (anti-inflammatory) and polyphenols with antioxidant activity in arterial tissue.

Oily fish (2–3 times weekly): EPA and DHA omega-3 fatty acids reduce triglycerides (a cardiovascular risk factor), reduce arterial inflammation, improve endothelial function, and stabilise heart rhythm. Wild salmon, mackerel, sardines, and tinned tuna are the most practical sources.

Legumes (several times weekly): Provide soluble fibre for LDL reduction, plant protein as a partial replacement for red meat, and polyphenols with antioxidant and anti-inflammatory activity. Lentils, chickpeas, black beans, and cannellini beans are the workhorses of heart-healthy cooking.

Whole grains (over refined grains): Provide beta-glucan soluble fibre (oats specifically — with the most consistent LDL-lowering evidence), B vitamins, and a more moderate blood glucose response than refined grains — reducing the insulin spikes associated with arterial inflammation.

Nuts and seeds (daily small amounts): Walnuts specifically provide both ALA omega-3 and ellagitannins with antioxidant activity. Almonds provide monounsaturated fat and plant sterols that reduce cholesterol absorption. A small daily handful — not a large portion — is the evidence-supported amount.

Abundant vegetables and fruits: Provide potassium (lowers blood pressure), antioxidants that protect arterial walls from oxidative damage, fibre for cholesterol management, and folate (reduces homocysteine, a cardiovascular risk marker).

Limited red meat, processed meat, added sugar, salt, and saturated fat: The dietary factors most consistently associated with increased cardiovascular risk in large epidemiological research.

BREAKFAST RECIPES

Recipe 1: Oat and Berry Heart Bowl

Cardiovascular focus: Soluble fibre for LDL reduction + antioxidant berry polyphenols Prep time: 10 minutes (overnight oats version: 5 minutes the night before)

Oats are the single most evidence-supported food for LDL cholesterol reduction through diet. Their beta-glucan soluble fibre forms a gel in the digestive tract that binds bile acids (which are made from cholesterol), preventing their reabsorption and signalling the liver to use more circulating cholesterol to make new bile acids — reducing LDL in the process. The FDA formally recognises this mechanism as sufficient to allow the health claim "may reduce the risk of heart disease" on oat products providing at least 3g of beta-glucan per day.

Ingredients (serves 1):

• 80g rolled oats (provides approximately 4g of beta-glucan)

• 300ml unsweetened almond milk or skimmed dairy milk

• 150g mixed berries (blueberries, raspberries, strawberries — anthocyanins for arterial health)

• 1 tablespoon ground flaxseed (ALA omega-3 + additional soluble fibre)

• 1 tablespoon walnuts, roughly broken (ALA omega-3 + ellagitannins)

• 1 teaspoon honey (optional)

• ½ teaspoon cinnamon (improves glucose response)

How to make it:

1. Stovetop: combine oats and milk in a small pan. Cook over medium heat, stirring regularly, for 5–6 minutes until creamy and thickened

2. Microwave: combine oats and milk in a bowl. Microwave on high for 2.5 minutes, stir halfway

3. Overnight oats: combine oats and cold milk in a jar the night before. Refrigerate overnight. Eat cold or warm briefly in the morning

4. Top with berries, flaxseed, walnuts, and honey if using

5. Finish with cinnamon

Cardiovascular highlights: Beta-glucan (4g — FDA-recognised cholesterol-lowering mechanism), anthocyanins from berries (arterial antioxidant protection), ALA omega-3 from flaxseed and walnuts, cinnamon for glucose response modulation.

Recipe 2: Smoked Salmon and Avocado Whole Grain Toast

Cardiovascular focus: Omega-3 for triglyceride reduction + monounsaturated fat for HDL maintenance Prep time: 8 minutes

A genuinely satisfying breakfast combining three of the strongest heart-healthy foods: smoked salmon (EPA and DHA omega-3), avocado (monounsaturated oleic acid — the same fat as in olive oil — alongside potassium for blood pressure), and whole grain bread (fibre and B vitamins over refined grain). Lemon juice brightens the flavour while providing vitamin C that supports collagen in arterial walls.

Ingredients (serves 1):

• 2 slices whole grain sourdough or rye bread

• 80g smoked salmon

• ½ ripe avocado, mashed or sliced

• Juice of ½ lemon

• Red onion, thinly sliced (quercetin — antioxidant flavonoid)

• Capers (quercetin + sodium note: rinse capers before using to reduce salt)

• Fresh dill

• Black pepper

How to make it:

1. Toast the whole grain bread

2. Mash or slice avocado — mash provides better coverage; a squeeze of lemon prevents browning and adds vitamin C

3. Layer avocado on toast, top with smoked salmon

4. Add red onion, capers, and fresh dill

5. Finish with black pepper and remaining lemon juice

Cardiovascular highlights: EPA + DHA omega-3 from smoked salmon (triglyceride reduction + endothelial function), monounsaturated fat from avocado (LDL lowering + HDL maintenance), potassium from avocado (blood pressure support), whole grain fibre, quercetin from red onion (arterial antioxidant protection).

LUNCH RECIPES

Recipe 3: Mediterranean Lentil Soup

Cardiovascular focus: Soluble fibre for LDL reduction + plant protein + polyphenols Prep time: 35 minutes | Batch cooks 4 days

Red lentils cook in 20 minutes without soaking and produce a silky, deeply satisfying soup when combined with garlic, turmeric, cumin, and a finishing squeeze of lemon. A single serving provides approximately 8g of dietary fibre alongside 18g of plant protein — addressing both the soluble fibre LDL-lowering mechanism and the plant protein replacement of less heart-healthy animal protein sources.

Ingredients (serves 4):

• 300g dry red lentils

• 1 litre low-sodium vegetable or chicken stock

• 1 tin (400g) chopped tomatoes

• 1 large onion, diced

• 4 garlic cloves, crushed

• 1 teaspoon turmeric

• 1 teaspoon cumin

• ½ teaspoon smoked paprika

• ½ teaspoon black pepper (always with turmeric for curcumin absorption)

• 3 tablespoons extra-virgin olive oil

• Juice of 1 lemon

• Fresh parsley

• Low-sodium salt to taste

How to make it:

1. Heat olive oil in a large pot over medium heat. Cook onion until softened (5 minutes)

2. Add garlic — cook 2 minutes. Add turmeric, cumin, paprika, black pepper — stir 30 seconds

3. Add rinsed lentils, tomatoes, and stock. Bring to a boil, then simmer 20 minutes until lentils are completely soft

4. Blend partially (leave some texture) or blend smooth — both work well

5. Finish with lemon juice, adjust seasoning, and top with fresh parsley

6. Drizzle a small amount of extra-virgin olive oil over each bowl before serving

Cardiovascular highlights: Lentil soluble fibre (LDL reduction through bile acid binding), plant protein (replacing higher saturated fat animal protein), lentil polyphenols (antioxidant + anti-inflammatory), garlic allicin (blood pressure support), turmeric curcumin with black pepper (anti-inflammatory NF-kB pathway), olive oil monounsaturated fat.

Recipe 4: Salmon and Quinoa Salad With Walnut Dressing

Cardiovascular focus: Omega-3 from two sources + complete plant protein + arterial antioxidants Prep time: 20 minutes

Wild salmon alongside quinoa (complete plant protein providing all essential amino acids) dressed with a walnut-based dressing providing ALA omega-3 from a plant source — addressing cardiovascular health through both marine and plant omega-3 pathways simultaneously. A genuinely satisfying lunch that covers three of the most important heart-healthy food categories in one bowl.

Ingredients (serves 2):

• 2 wild salmon fillets (approximately 130g each)

• 160g dry quinoa (cooked)

• 100g rocket and spinach

• 1 red pepper, diced (vitamin C + potassium)

• ½ cucumber, diced

• 100g cherry tomatoes, halved

• 2 tablespoons fresh parsley

Walnut and lemon dressing:

• 3 tablespoons extra-virgin olive oil

• 1 tablespoon walnut oil (or 2 tablespoons crushed walnuts blended in)

• Juice of 1 lemon

• 1 teaspoon Dijon mustard

• 1 garlic clove, grated

• Salt and black pepper

How to make it:

1. Cook quinoa according to packet instructions. Cool slightly

2. Season salmon with salt, pepper, and a drizzle of olive oil. Pan-fry skin-side down over medium-high heat for 4–5 minutes. Flip, cook 2–3 more minutes until just cooked through

3. Whisk all dressing ingredients together

4. Combine cooled quinoa, rocket, spinach, red pepper, cucumber, and tomatoes

5. Toss with dressing

6. Top with salmon and fresh parsley

Cardiovascular highlights: EPA + DHA omega-3 from wild salmon (triglycerides + inflammation + heart rhythm), ALA omega-3 from walnut oil (plant-based cardiovascular support), quinoa complete protein, olive oil monounsaturated fat, red pepper potassium and vitamin C, tomato lycopene (antioxidant, LDL oxidation protection).

Recipe 5: Sardine and White Bean Toast

Cardiovascular focus: Omega-3 + soluble fibre + plant sterols — three LDL-lowering mechanisms in one Prep time: 10 minutes

Sardines are one of the most omega-3-dense, most affordable, and most nutritionally complete foods available — providing approximately 2g of EPA+DHA per 100g alongside vitamin D, calcium (from the soft edible bones), and selenium. Paired with cannellini beans (soluble fibre + plant sterols) on whole grain toast, this provides three simultaneous LDL-reducing mechanisms: omega-3 for triglyceride reduction, soluble fibre for bile acid binding, and plant sterols that directly block dietary cholesterol absorption.

Ingredients (serves 1):

• 1 tin sardines in olive oil or water (approximately 100g drained)

• 3 tablespoons cannellini beans, drained and lightly mashed

• 2 slices whole grain or sourdough bread, toasted

• 1 tablespoon extra-virgin olive oil

• Juice of ½ lemon

• Fresh parsley, finely chopped

• Red pepper flakes, black pepper

• Optional: sliced tomato, red onion

How to make it:

1. Drain sardines. If using sardines in olive oil, the oil can be drizzled over the toast as an additional heart-healthy fat source

2. Lightly mash cannellini beans with a fork — leave some texture, not fully smooth

3. Toast bread

4. Spread mashed beans on each slice

5. Top with sardines

6. Drizzle olive oil and lemon juice

7. Finish with fresh parsley, chilli flakes, and black pepper

Cardiovascular highlights: EPA + DHA from sardines (~2g — exceeds the American Heart Association recommendation per serving), soluble fibre from cannellini beans (LDL reduction), plant sterols from beans (cholesterol absorption inhibition), whole grain fibre, olive oil monounsaturated fat, vitamin D from sardines (cardiovascular relevance).

DINNER RECIPES

Recipe 6: Baked Salmon With Roasted Mediterranean Vegetables

Cardiovascular focus: Omega-3 + polyphenol-rich vegetables + olive oil — the Mediterranean diet in one dish Prep time: 35 minutes

A one-pan dinner that captures the three pillars of the Mediterranean dietary pattern most associated with the PREDIMED trial's 30% cardiovascular event risk reduction: oily fish, abundant vegetables, and extra-virgin olive oil. The vegetables — aubergine, courgette, cherry tomatoes, red pepper — provide lycopene, anthocyanins, and potassium alongside the dietary fibre that is consistently associated with reduced cardiovascular risk.

Ingredients (serves 2):

• 2 wild salmon fillets (150g each)

3. Push vegetables to the sides of the tray. Season salmon and place in the centre. Drizzle remaining olive oil over salmon

4. Return to oven for 12–15 minutes until salmon is just cooked through

5. Squeeze lemon over everything. Finish with fresh basil

Cardiovascular highlights: Wild salmon EPA + DHA (triglycerides, inflammation, endothelial function), extra-virgin olive oil (monounsaturated fat + oleocanthal anti-inflammatory + PREDIMED intervention fat), roasted tomato lycopene (LDL oxidation protection), aubergine nasunin (antioxidant), red pepper potassium (blood pressure), garlic allicin (blood pressure + LDL).

Recipe 7: Chickpea and Spinach Stew With Feta

Cardiovascular focus: Plant protein + soluble fibre + anti-inflammatory herbs and spices Prep time: 30 minutes

A deeply satisfying plant-based dinner providing 22g of protein per serving from chickpeas alongside 12g of fibre — one of the highest-fibre dinners in this guide. The combination of cumin, coriander, and smoked paprika produces a rich, warming flavour that makes this feel like comfort food rather than a health-conscious meal. Spinach provides potassium and folate relevant to blood pressure and homocysteine metabolism.

Ingredients (serves 3):

• 2 tins (800g) chickpeas, drained

• 200g fresh spinach

• 1 tin (400g) chopped tomatoes

• 1 large onion, diced

• 4 garlic cloves, crushed

• 1 teaspoon cumin

• 1 teaspoon coriander

• 1 teaspoon smoked paprika

• ½ teaspoon turmeric

• ¼ teaspoon black pepper

• 3 tablespoons extra-virgin olive oil

• 100g feta cheese, crumbled

• Juice of ½ lemon

• Fresh coriander or parsley

How to make it:

1. Heat olive oil in a large pan over medium heat. Cook onion until softened (5 minutes)

2. Add garlic and all spices — cook 2 minutes until fragrant

3. Add chickpeas and tomatoes. Stir well and simmer 12–15 minutes until slightly thickened

4. Add spinach and stir until wilted (2 minutes)

5. Finish with lemon juice. Adjust seasoning

6. Serve topped with crumbled feta and fresh coriander

Cardiovascular highlights: Chickpea soluble fibre (LDL reduction + bile acid binding), chickpea plant sterols (cholesterol absorption inhibition), chickpea plant protein (replacing higher saturated fat meat protein), spinach potassium and folate (blood pressure and homocysteine), olive oil monounsaturated fat, garlic allicin, turmeric + black pepper curcumin.

Recipe 8: Mackerel With Butter Bean Mash and Greens

Cardiovascular focus: Highest omega-3 dinner in the guide + legume soluble fibre + dark green veg potassium Prep time: 25 minutes

Mackerel has a higher omega-3 concentration per gram than salmon — making it the most omega-3-dense dinner in this guide — combined with butter bean mash (a heart-healthy alternative to mashed potato, providing soluble fibre and plant protein) and dark leafy greens (kale or spinach, providing potassium, folate, and vitamin K). The butter bean mash is one of the most practically useful techniques in this guide: silky, satisfying, and ready in 5 minutes.

Ingredients (serves 2):

• 2 mackerel fillets (approximately 180g each)

• 2 tins (800g) butter beans, drained

• 200g kale or spinach

• 4 garlic cloves: 2 for the bean mash, 2 for the greens

• 4 tablespoons extra-virgin olive oil

• Juice of 1 lemon

• Fresh thyme

• Salt, black pepper

How to make it:

1. Butter bean mash: Heat 2 tablespoons olive oil in a pan. Add 2 crushed garlic cloves, cook 1 minute. Add butter beans and warm through. Add a splash of warm water and mash or blend to a creamy consistency. Season well, add lemon juice

2. Greens: Wilt kale or spinach in a pan with olive oil and crushed garlic for 3–4 minutes. Season

3. Mackerel: Season fillets. Pan-fry skin-side down in a little olive oil over high heat for 4 minutes. Flip, cook 2 more minutes

4. Serve mackerel over butter bean mash alongside wilted greens. Drizzle any remaining olive oil and lemon over the plate

Cardiovascular highlights: Mackerel EPA + DHA (highest omega-3 per gram of any common fish — triglycerides, inflammation, heart rhythm), butter bean soluble fibre and plant sterols (LDL reduction), kale potassium and folate (blood pressure and homocysteine), olive oil monounsaturated fat, garlic allicin.

Recipe 9: Walnut and Roasted Vegetable Whole Grain Pasta

Cardiovascular focus: Plant sterols and ALA omega-3 from walnuts + whole grain fibre + abundant vegetables Prep time: 30 minutes

A genuinely satisfying pasta dish built around whole grain pasta (the fibre and B vitamins of the whole grain versus none of these in refined pasta), roasted Mediterranean vegetables, and a walnut-based sauce that provides both ALA omega-3 and the ellagitannins converted to urolithins in the gut. The walnut crumble mimics the texture and satisfaction of a meat-based sauce without the saturated fat.

Ingredients (serves 3):

• 240g whole grain pasta (wholemeal penne or rigatoni)

• 100g walnuts, roughly blended or very finely chopped (the "walnut meat")

• 1 aubergine, diced small

• 2 courgettes, diced small

• 300g cherry tomatoes, halved

• 1 red onion, diced

• 4 garlic cloves, crushed

• 4 tablespoons extra-virgin olive oil

• 1 tin (400g) chopped tomatoes

• 1 teaspoon dried oregano

4. Add tinned tomatoes and oregano. Simmer 8 minutes. Add roasted vegetables

5. Drain pasta, add to the sauce. Toss everything together

6. Finish with fresh basil and a small amount of Parmesan if using

Cardiovascular highlights: Walnuts (ALA omega-3 + ellagitannins + plant sterols — LDL reduction), whole grain pasta fibre (versus refined grain), abundant roasted vegetables (polyphenols, potassium, fibre), olive oil monounsaturated fat (PREDIMED primary intervention fat), tomato lycopene (LDL oxidation protection).

Recipe 10: Mediterranean Baked Cod With Olives, Tomatoes, and Capers

Cardiovascular focus: Lean white fish protein + olive oil polyphenols + Mediterranean dietary pattern Prep time: 25 minutes

Cod is a lean, mild white fish providing complete protein with minimal saturated fat — a heart-healthy protein source that is practical, affordable, and versatile. Baked in a Mediterranean sauce of olive oil, olives, cherry tomatoes, capers, and garlic, it demonstrates how the Mediterranean dietary pattern produces genuinely flavourful food rather than bland health eating. Olives provide additional oleic acid and hydroxytyrosol — an olive polyphenol with specific research interest in cardiovascular health.

Ingredients (serves 2):

• 2 cod fillets (approximately 150g each)

• 200g cherry tomatoes, halved

• 60g kalamata olives, pitted and halved

• 2 tablespoons capers, rinsed (rinse to reduce sodium)

• 4 garlic cloves, thinly sliced

• 3 tablespoons extra-virgin olive oil

• 100ml dry white wine (optional) or vegetable stock

• 1 teaspoon dried oregano

• Juice of ½ lemon

• Fresh parsley

• Salt, black pepper

How to make it:

1. Preheat oven to 200°C

2. In an ovenproof dish, combine cherry tomatoes, olives, capers, garlic slices, olive oil, wine or stock, and oregano. Stir to combine

3. Roast the tomato-olive mixture for 10 minutes until tomatoes are beginning to soften

4. Nestle cod fillets into the mixture. Season with salt, pepper, and a squeeze of lemon

5. Return to oven for 12–15 minutes until cod is opaque and flakes easily

6. Finish with fresh parsley and remaining lemon juice

Cardiovascular highlights: Cod lean protein (high-quality protein with minimal saturated fat — heart-healthy protein source), extra-virgin olive oil oleocanthal and polyphenols (PREDIMED intervention fat + anti-inflammatory), olives hydroxytyrosol (cardiovascular polyphenol with specific research interest), capers quercetin, tomato lycopene, garlic allicin.

What to Limit — The Other Side of Heart-Healthy Eating

The 2026 American Heart Association guidance is explicit: diet reduces cardiovascular risk not only through what is added but through what is reduced. The foods most consistently associated with increased cardiovascular risk:

Ultra-processed foods: Consistently associated with higher cardiovascular mortality across large cohort studies — the combination of refined carbohydrates, saturated and trans fats, high sodium, and additive-heavy processing creates a cardiovascular risk profile that goes beyond any single nutrient.

Salt (sodium): Elevated sodium intake raises blood pressure — the most common cardiovascular risk factor. The AHA recommends less than 2,300mg daily (approximately 1 teaspoon of salt total from all sources). The recipes in this guide use herbs, spices, lemon, garlic, and good olive oil to provide flavour without reliance on salt.

Saturated fat (from processed red meat and full-fat dairy): Replaces LDL-lowering unsaturated fat in the diet and is associated with higher LDL cholesterol and cardiovascular risk. This guide does not eliminate red meat or dairy — it shifts the primary fat and protein sources toward fish, legumes, olive oil, and nuts, with red meat and full-fat dairy as occasional rather than daily foods.

Added sugar: Drives triglyceride production in the liver — triglycerides are an independent cardiovascular risk factor — and promotes visceral fat accumulation with its associated inflammatory and hormonal effects on cardiovascular risk.

Frequently Asked Questions

Is the Mediterranean diet safe for people with high cholesterol?

The Mediterranean dietary pattern is specifically recommended by the American Heart Association as one of the best heart-healthy eating patterns available for people with elevated cholesterol. Its combination of soluble fibre (for LDL reduction through bile acid binding), monounsaturated fat (for LDL lowering without HDL reduction), plant sterols (from legumes and nuts — for cholesterol absorption inhibition), and omega-3 fatty acids (for triglyceride reduction) addresses multiple lipid pathways simultaneously. People with medically diagnosed dyslipidaemia should work with their doctor or dietitian alongside any dietary changes.

How much olive oil is too much?

The PREDIMED trial intervention group consumed approximately 4 tablespoons (50ml) of extra-virgin olive oil daily — a generous amount that produced significant cardiovascular benefit. Olive oil is calorie-dense (approximately 120 calories per tablespoon) — the heart-healthy benefit comes from using it to replace less healthy fat sources rather than adding it on top of an otherwise high-fat diet. The practical approach: use extra-virgin olive oil as the primary cooking fat and dressing fat, replacing butter, margarine, and refined vegetable oils.

Should I take omega-3 supplements if I don't eat fish?

For people who do not eat oily fish, ALA omega-3 from plant sources (walnuts, flaxseed, chia seeds) provides some cardiovascular benefit, though EPA and DHA from marine sources have stronger and more consistent cardiovascular research behind them. A high-quality omega-3 supplement (fish oil or algae-based for vegans) is a reasonable consideration for people who do not eat oily fish — discuss with your doctor, particularly as omega-3 supplements interact with some blood-thinning medications.
