Quick Answer
Nuts and seeds support heart health through unsaturated fats, fibre, plant protein, magnesium and vitamin E. Walnuts, almonds, pistachios, flaxseed, chia and pumpkin seeds are standout choices. A sensible daily portion is about a small handful, roughly 30 grams, or one to two tablespoons of seeds. Choosing unsalted, unsweetened versions keeps the benefits without adding extra sodium or sugar.
The Most Heart-Friendly Nuts and Seeds
Walnuts are notable for their plant omega-3 fat, ALA, and have been studied in relation to healthy cholesterol levels. Almonds provide vitamin E and magnesium. Pistachios bring potassium and are lower in calories per nut, so a portion looks bigger. Peanuts are technically legumes but share a similar nutrient profile and are an affordable everyday option for most households.
Seeds pack a lot into a spoonful. Ground flaxseed gives ALA and fibre, though it needs grinding to be absorbed well. Chia seeds swell in liquid and add soluble fibre to oats and yogurt. Pumpkin seeds are rich in magnesium, while sunflower seeds offer vitamin E. Sesame seeds, including tahini, add calcium and a rich nutty flavour to dressings.
How to Add Them Without Overdoing It
Because nuts are energy-dense, portion matters. Pre-portion a handful into small tubs rather than eating from the bag. Sprinkle seeds over porridge, yogurt or salads, stir nut butter into oats, and use chopped walnuts or almonds instead of croutons. A tablespoon of tahini with lemon and garlic makes a simple dressing for roasted vegetables or chickpea bowls.
Watch for salted, honey-roasted or chocolate-coated versions, which change the profile considerably. Choose plain, dry-roasted or raw nuts, and nut butters made only from nuts. Swapping a biscuit or crisps for a handful of almonds is one of the easiest switches. Mixing several types across the week gives a broader range of fats, minerals and antioxidants.
