Sunflower seeds are slightly tear-shaped and grow in the head of the sunflower. Each seed has an outer shell or hull and an inner seed or kernel. Sunflowers are of course the big, bright sunny yellow and black flowers that grow over 5ft fall. They famously turn to face the sun across the day and do well in hot weather. Sunflowers themselves belong to the Asteraceae family and are related to daisies, marigolds, chrysanthemums, echinacea and yarrow. Sunflowers originated in America, with Indigenous Americans cultivating sunflower seeds as early as 3000 BC.
Widespread production of sunflowers began in Europe in the 16th century. Commercially the outer husk of the seeds appears either solid black or striped. They are used in cereals and baked goods or processed to yield sunflower oil for cooking. The three varieties of sunflower seeds include linoleic, high oleic and regular sunflower oil seeds. Each has a special profile of healthy fats, varying in monounsaturated, saturated or polyunsaturated fats.

Some Sunflower Seed Health Benefits
The benefits of sunflower seeds are comparable to the benefits of many nuts and seeds like Chia Seeds. In fact sunflower seeds could rival almonds for their vitamin E content. They are also fairly high in protein as far as seeds go. They have historically been used in traditional European cultures to treat upper respiratory conditions, including coughs and the common cold. Sunflower seeds have a range of beneficial therapeutic actions. Here’s what the data shows:
- Hormone support
- Weight management
Sunflower Seeds & Ovarian Cycle Function
This may well be a long bow to draw, but it’s not a bad concept if it means getting more sunflower seeds into your daily diet. Sunflower seeds feature in the relatively popular fad of seed cycling. Here, flaxseeds, pumpkin seeds, sesame seeds and sunflower seeds are used interchangeably at various times in a woman’s ovarian cycle. The goal is to improve the nutrient reserves that affect hormones as they peak and fall over the course of the follicular and luteal phases. I go into more detail on this protocol together with a healthy recipe here.
Sunflower Seed Extract Supports Healthy Weight
A 2019 study demonstrated the metabolic effects of sunflower seeds in a group of overweight participants. The authors noted improvements in body weight and cholesterol and concluded sunflower seeds to be a healthy addition in obesity-related conditions.
Soaking Sunflower Seeds Boosts Antioxidant Potential
The antioxidant properties of sunflower seeds are prone to degradation over time. A process known as osmopriming, which involves soaking seeds in a solution of low water potential, appears to reinvigorate aged seeds. This process progressively restores antioxidant defence systems of sunflower seeds. This was demonstrated not only by an increase in substances such as superoxide dismutase and glutathione reductase, but also the reduction in lipid peroxidation of the cell wall.
How to Enjoy Sunflower Seeds
- Enjoy them raw or roasted with seasoning as a snack.
- Make a praline by dousing them in caramel and setting on a baking tray.
- Toss them in a salad
- Throw them in your homemade granola or add to your porridge.
- Sunflower seeds are also used in Russia to make halva.
- Alternatively you can eat them sprouted in a salad for an extra dose of dietary zinc.
- Consume them in a ground meal like LSA
Because of their mild taste they really can go into all kinds of dishes, both sweet and savoury.
Nut Butter Alternative? Try Sunflower Seed Butter
Sunflower seed butter is a wonderful alternative to traditional nut butters if you’ve got nut allergies or just want to try something new. High in protein and healthy fats, and often cheaper than some nut butters, sunflower seed butter has a mild flavour and makes a great pairing with sliced strawberries on sourdough. Yum! Have a look at some delicious nut butter ideas here.
How to Store Sunflower Seeds
Sunflower seeds are sensitive to oxidation and going ‘off’ just the same as other seeds and nuts. Keeping your sunflower seeds in an airtight container in the fridge is ideal. However, storing sunflower seeds on a shelf away from direct sunlight is also fine. They should last for several months.
Linguine with Blue Cheese and Sunflower Seeds
A bit special in more ways than one. This pasta dish is elegant with just a few ingredients. Not everyone likes blue cheese, and that’s totally fair enough! However the sauce is balanced well and the sunflower seeds give added texture and depth. I hope you give it a go.
1 packet of linguine or spaghettini
1 shallot or small onion, peeled and chopped
90g blue cheese
1 tbsp. Sunflower oil
1 ¾ cup sour cream
½ tsp. Pepper
40g roasted sunflower kernels
Chopped parsley to serve
- Cook pasta according to package directions, until just al dente.
- Meanwhile, heat a pan on medium heat, fry shallot or onion in butter.
- Add sour cream and warm slightly until sauce thickens.
- Crumble blue cheese with a fork, add to sour cream mixture, and stir until melted.
- Season with pepper.
- Add 20g sunflower seeds to the blue cheese sauce and stir through.
- Add the pasta to the sauce and coat evenly.
- Serve with chopped parsley and remaining sunflower kernels.
