The 6 Best Seeds to Add to Your Diet and What Each One Does for Your B

The six seeds in this guide were chosen because they each do something meaningfully different for the body. They are not interchangeable — chia seeds and sesame seeds serve very different nutritional roles, and knowing the difference helps you make better decisions about which to prioritise. Each one is also an ingredient you can find in your kitchen year-round, not a seasonal or specialist product.

6 seeds covered in this guide

1–2 tbsp is a meaningful daily serving

100% plant-based protein sources

All naturally gluten free

Chia Seeds

The omega-3 and hydration seed

Omega-3 ALA Soluble fibre Calcium Complete protein Antioxidants

What they do

Chia seeds are one of the richest plant sources of alpha-linolenic acid (ALA), the plant form of omega-3 fatty acid, which supports heart health and reduces inflammation. They are also exceptionally high in soluble fibre — when soaked, they form a gel that slows digestion, helps regulate blood sugar, and keeps you full for longer. A 30g serving provides more calcium than a glass of milk, making them particularly useful in dairy-free diets. Their complete amino acid profile is unusual for a plant food.

Daily use

Soak overnight in plant milk for chia pudding
Stir into porridge or overnight oats
Use as an egg substitute in vegan baking (1 tbsp + 3 tbsp water)
Blend into smoothies — no flavour, added nutrition
Scatter over yogurt or fruit bowls

Try them in

Chia is one of the five ingredients in our Omega Seed Mix Overnight Porridge with Berries — a no-cook breakfast that uses the seeds' natural gelling ability to create a creamy, filling bowl.

Flaxseed (Linseed)

The gut and hormone health seed

Lignans Insoluble fibre Omega-3 ALA Magnesium

What they do

Flaxseed is the richest dietary source of lignans — plant compounds that have a mild oestrogen-like effect in the body and are associated with hormone balance, particularly in women. It is also high in both soluble and insoluble fibre, supporting regular bowel movements and feeding beneficial gut bacteria. Ground flaxseed is significantly more bioavailable than whole — the body cannot break down the outer hull, so grinding before use unlocks the nutrients inside. Store ground flaxseed in the fridge and use within a few weeks.

Daily use

Grind and stir into porridge, soups, or smoothies
Use as a binding agent in baking (flax egg)
Add to bread dough or homemade crackers
Mix into yogurt or overnight oats
Sprinkle over salads — ground form recommended

Try them in

Flaxseed appears alongside chia in the Omega Seed Mix Overnight Porridge with Berries — and it is one of the five core ingredients in our no-bake Omega Seed Energy Balls.

You do not need to eat large quantities of seeds to benefit from them. One to two tablespoons daily, rotated across a few varieties, covers a meaningful range of nutrients that are difficult to get from other everyday foods.

Pumpkin Seeds

The mineral powerhouse

Zinc Magnesium Iron Plant protein Tryptophan

What they do

Pumpkin seeds punch well above their weight in terms of mineral content. A 30g serving provides a significant proportion of the daily recommended intake for zinc — essential for immune function, wound healing, and testosterone production — as well as magnesium, which supports sleep quality, muscle recovery, and hundreds of enzymatic processes in the body. They are also a notable source of tryptophan, an amino acid precursor to serotonin and melatonin, which may support mood and sleep. Their iron content makes them particularly valuable in plant-based diets.

Daily use

Roast with olive oil and sea salt for snacking
Scatter over soups, salads, and grain bowls
Blend into pesto as a nut-free alternative
Add to homemade granola and trail mixes
Press into bread dough before baking

Try them in

Pumpkin seeds are one of the key toppings in the Rye Flour Sourdough Crackers with Seeds — a simple bake where the seeds toast into the surface of the cracker for a satisfying crunch.

Sesame Seeds

The bone and blood pressure seed

Calcium Sesamin Copper Healthy fats Phytosterols

What they do

Sesame seeds are among the highest plant sources of calcium by weight, making them a valuable addition to dairy-free diets. They also contain sesamin and sesamolin — two unique lignans that have been studied for their anti-inflammatory properties and potential effects on blood pressure and cholesterol. Their phytosterol content supports cardiovascular health by competing with dietary cholesterol for absorption. Tahini (ground sesame paste) concentrates all of these benefits and is one of the more bioavailable ways to consume sesame, as grinding breaks down the hull and improves nutrient absorption.

Daily use

Toast lightly and scatter over stir-fries and noodles
Use tahini in dressings, hummus, and sauces
Press into bread or flatbreads before baking
Add to energy balls and no-bake bars
Blend into smoothies for a subtle nuttiness

Try them in

Sesame seeds are the hero ingredient in the Sesame Seed Halva Energy Bars — a no-bake, refined sugar-free bar that uses tahini as its base for a rich, nutty result.

On whole vs ground seeds

For flaxseed and sesame, grinding or using as tahini significantly increases how much nutrition your body can absorb. Whole seeds often pass through undigested. For chia, pumpkin, and sunflower seeds, whole seeds are fine — the outer coat is soft enough to digest without processing.

Sunflower Seeds

The vitamin E and skin health seed

Vitamin E Selenium B vitamins Linoleic acid Plant protein

What they do

Sunflower seeds are one of the best dietary sources of vitamin E — a fat-soluble antioxidant that protects cell membranes from oxidative damage, supports skin health, and plays a role in immune function. A single 30g serving covers a large portion of the daily recommended intake. They are also high in selenium, a trace mineral important for thyroid function and DNA repair, and contain a good range of B vitamins, particularly B1 (thiamine) and B6, which support energy metabolism and nervous system health.

Daily use

Add to homemade granola and muesli
Use as a nut-free topping on salads and bowls
Blend into sunflower seed butter
Mix into energy balls and no-bake bars
Press into seeded loaves and crackers

Try them in

Sunflower seeds are one of the five core ingredients in our no-bake Omega Seed Energy Balls — a 15-minute recipe that showcases how well they pair with chia, flaxseed, and dates.

Organic Omega Seed Mix

The all-in-one daily addition

Omega-3 & 6 Broad spectrum minerals Multi-fibre Protein variety

What it does

If you want the benefits of multiple seeds without keeping five separate bags on the shelf, a quality omega seed mix delivers a broad nutritional profile in one ingredient. A well-balanced mix typically combines chia, flax, sunflower, and pumpkin seeds to cover omega-3 fatty acids, fibre, zinc, magnesium, and vitamin E in a single tablespoon. Rotating or blending seed types also ensures you benefit from the unique lignans, phytosterols, and micronutrients that no single seed covers alone. This is the most practical entry point if seeds are new to your diet.

Daily use

One to two tbsp over porridge or overnight oats
Stir into smoothies or yogurt
Press into homemade crackers or seeded loaves
Use as the base for no-bake energy balls
Scatter over soups and salads

Try it in

The Omega Seed Mix Overnight Porridge with Berries was designed specifically for the mix — five minutes of prep the night before and a genuinely filling, nutritious breakfast ready in the morning.

How to Start Adding Seeds to Your Diet

The simplest approach is to pick one seed and add a tablespoon of it to something you already eat every day — porridge, yogurt, a smoothie, or a salad. Do that consistently for a week before adding a second variety. This makes it a habit rather than a project, and means you will actually notice how each one integrates into your existing routine.

Buying certified organic seeds matters more than it might seem for an ingredient you use daily in its raw, unprocessed form — there is no cooking step to remove residues. Our full organic seeds range covers all six varieties listed in this guide, including individual seeds and omega mixes, all grown without synthetic pesticides or fertilisers.

Store seeds in airtight containers away from heat and light. Most keep well for three to six months in a cool cupboard. Ground flaxseed and chia, once opened, are best kept in the fridge to prevent the oils from going rancid.
