Seeds are nutritious foods that provide protein, healthy fats, dietary fibre, vitamins, minerals and antioxidants. Including different types of seeds in a balanced diet may support heart health, digestion, skin health and overall well-being.
1. Sunflower Seeds
Scientific name: Helianthus annuus
Key nutrients: Vitamin E, protein, magnesium, selenium and healthy fats.
Health benefits
- Supports skin health: Vitamin E acts as an antioxidant and helps protect cells against oxidative damage.
- Promotes heart health: Sunflower seeds contain unsaturated fats that can support healthy cholesterol levels when they replace saturated fats in the diet.
- Supports hair health: They provide protein and micronutrients required for normal hair growth.
- Helps muscle function: Magnesium contributes to normal muscle and nerve function.
- Provides antioxidant protection: Vitamin E helps protect cells from oxidative stress.
- Supports energy metabolism: B vitamins and minerals contribute to the body’s normal energy-producing processes.
Recommended intake: Approximately 10–15 grams per day.
How to consume: Eat them raw or lightly roasted without excessive salt. Add them to salads, oatmeal, yoghurt, smoothies or homemade seed mixtures.
Precautions: Sunflower seeds are calorie-dense. Choose unsalted varieties if you need to limit sodium intake.
2. Pumpkin Seeds
Scientific name: Cucurbita species
Key nutrients: Zinc, magnesium, protein, iron and unsaturated fats.
Health benefits
- Supports immune function: Zinc is essential for normal immune system function.
- Supports reproductive health: Zinc contributes to normal reproductive function in men and women.
- Promotes muscle health: Magnesium helps maintain normal muscle and nerve function.
- Supports bone health: Magnesium and phosphorus contribute to healthy bones.
- Contributes to heart health: Unsaturated fats and magnesium support a heart-healthy dietary pattern.
- Helps maintain muscles: Protein supports tissue repair and muscle maintenance.
Recommended intake: Approximately 10–15 grams per day.
How to consume: Eat shelled pumpkin seeds raw or lightly roasted. They can be added to salads, soups, porridge, vegetable dishes and breakfast cereals.
Precautions: Pumpkin seeds are nutritious but are not a proven treatment for infertility or prostate disease.
3. Chia Seeds
Scientific name: Salvia hispanica
Key nutrients: Omega-3 fatty acid ALA, dietary fibre, protein, calcium, phosphorus and magnesium.
Health benefits
- Improves digestive health: Dietary fibre supports regular bowel movements and may help prevent constipation.
- Supports weight management: Chia seeds absorb water and form a gel, which may help you feel full for longer.
- Supports heart health: Their fibre and plant-based omega-3 fatty acids contribute to a balanced diet.
- Helps manage blood sugar: Fibre may slow digestion and moderate the rise in blood glucose after meals.
- Supports bone health: They supply calcium, phosphorus and magnesium.
- Provides plant-based omega-3: ALA is an essential fatty acid that the body needs from food.
Recommended intake: Start with 1 teaspoon and gradually increase to approximately 1 tablespoon, or 12 grams, per day if tolerated.
How to consume: Soak chia seeds in water or milk for 15–30 minutes. Add them to smoothies, oatmeal, yoghurt or homemade chia pudding.
Precautions: Do not swallow a spoonful of dry chia seeds, as they expand after absorbing liquid and may cause swallowing problems. Drink sufficient water and increase fibre gradually.
4. Black Sesame Seeds
Scientific name: Sesamum indicum
Key nutrients: Calcium, iron, copper, healthy fats, protein and lignans.
Health benefits
- Supports bone health: Sesame seeds provide minerals involved in maintaining healthy bones.
- Provides antioxidants: Sesame lignans, including sesamin, have antioxidant properties.
- Supports heart health: Their unsaturated fats can contribute to a heart-healthy diet.
- Supports normal body functions: Copper and iron contribute to several important physiological processes.
- Contributes to skin nutrition: Healthy fats and minerals help meet the body’s nutritional requirements.
- Adds nutritional variety: Black sesame seeds provide a convenient source of minerals and healthy fats.
Recommended intake: Approximately 5–10 grams per day.
How to consume: Add black sesame seeds to chutneys, salads, vegetables, homemade bread or seed powder. Light roasting can improve their flavour.
Important clarification: There is insufficient scientific evidence that black sesame seeds reverse grey hair or reliably increase melanin production. Hair colour is influenced by genetics, age and other factors, including certain nutritional deficiencies.
Precautions: Avoid sesame seeds if you have a sesame allergy.
5. Flax Seeds (Alsi)
Scientific name: Linum usitatissimum
Key nutrients: Omega-3 fatty acid ALA, dietary fibre, protein and lignans.
Health benefits
- Supports cholesterol management: Flaxseed, particularly ground flaxseed, may help improve cholesterol levels in some people.
- Improves bowel regularity: Its fibre can help relieve constipation.
- Supports heart health: ALA and fibre contribute to a heart-healthy eating pattern.
- May help with blood sugar management: Fibre can slow digestion and may moderate post-meal blood glucose responses.
- Provides antioxidant compounds: Lignans are plant compounds being studied for their potential health effects.
- Supports general nutrition: Flaxseed provides healthy fats, protein and dietary fibre.
Recommended intake: Start with 1 teaspoon of ground flaxseed and gradually increase to approximately 1 tablespoon, or 7–10 grams, per day.
How to consume: Grind the seeds before eating. Add them to oatmeal, yoghurt, smoothies or whole-wheat flour for rotis.
Precautions:
- Drink enough water when increasing fibre intake.
- Avoid raw or unripe flaxseeds.
- If you take blood-thinning medication, consult your doctor before using concentrated flaxseed supplements or making substantial dietary changes.
6. Hemp Seeds
Scientific name: Cannabis sativa
Key nutrients: Plant-based protein, omega-3 and omega-6 fatty acids, magnesium, iron and zinc.
Health benefits
- Supports muscle maintenance: Hemp seeds provide protein containing essential amino acids.
- Supports heart health: Their unsaturated fats can replace less healthy fat sources.
- Supports energy metabolism: Magnesium contributes to normal energy production.
- Supports skin health: Essential fatty acids help maintain normal skin function.
- Provides plant-based protein: Hemp seeds are a useful option for vegetarian and vegan diets.
- Contributes to mineral intake: They provide magnesium, iron and zinc.
Recommended intake: Approximately 10 grams per day, or 1 tablespoon of hulled hemp seeds.
How to consume: Add them to salads, soups, oatmeal, smoothies, yoghurt or cooked vegetables.
Precautions: Food-grade hemp seeds are different from cannabis products containing intoxicating THC. People with chronic kidney disease should consult a healthcare professional about suitable portions and mineral intake.
7. Black Cumin Seeds (Kalonji)
Scientific name: Nigella sativa
