10 benefits of chia seeds – plus uses and recipes

Small but mighty, chia seeds are a simple way to add fibre, plant-based protein, omega-3 fatty acids and minerals to your diet. But are chia seeds good for you… And how much should you eat each day? With help from our nutritionist, Molly Arnold, we’ve looked into everything you need to know about chia seeds and how you can enjoy them daily, including the latest evidence and practical tips.

Chia seeds are tiny, oval-shaped seeds from the Salvia hispanica plant, which belongs to the mint family. They can be black, grey, brown or white and are only a few millimetres across. The plant is native to parts of Mexico and Central America, where chia has a long history as a food. Chia seeds were an important crop for ancient Mesoamerican cultures, including the Aztecs and Mayans. The word ‘chia’ is commonly associated with the Mayan word for strength.

Today, chia seeds are widely used as a nutritious ingredient in everything from breakfast bowls and smoothies to baked goods and desserts. Their appeal is partly down to their nutritional profile. “Chia seeds might be small, but they’re packed with nutrients. They provide fibre, plant-based protein and omega-3 fatty acids, alongside minerals such as iron and selenium," says Molly.¹ "They’re a great example of how small additions to our everyday meals can help increase the variety of nutrients in our diet.” They also have a particularly useful culinary property: when mixed with liquid, chia seeds absorb it and develop a soft, gel-like coating. This makes them versatile in both sweet and savoury recipes.

A typical  28g serving of chia seeds – roughly two tablespoons – provides approximately:

*Values can vary between products and food-composition databases, so check the product label for the most accurate information. Chia seeds also provide minerals including calcium, magnesium, phosphorus, iron, zinc, copper, manganese and selenium.

Yes, chia seeds can be a nutritious addition to a balanced diet. They’re particularly useful for increasing your intake of fibre and plant-based foods, while also providing protein, ALA and a range of minerals. However, it’s important not to overstate what chia seeds can do.

Chia seeds are nutritious, but they’re not a miracle food. Research into their effects on blood pressure, cholesterol, blood sugar and body weight is ongoing. Recent reviews have found some promising results, particularly for blood pressure, but the evidence remains mixed and studies are generally relatively small.² So, rather than thinking of chia seeds as a treatment for a particular health condition, it’s more useful to see them as one nutritious ingredient that can contribute to an overall healthy eating pattern.

Chia seeds are packed with a range of important nutrients that can support your overall health and wellbeing. From omega-3 fatty acids and fibre to protein – here’s why these tiny seeds are worth adding to your diet.

Chia seeds are a source of omega-3 ALA

“Chia seeds are a useful plant-based source of omega-3 fatty acids, particularly alpha-linolenic acid (ALA), which is an essential fatty acid that our bodies can’t produce themselves," says Molly.^1,3 “Including foods such as chia seeds, walnuts and flaxseeds can help provide a variety of unsaturated fats as part of a balanced diet.” ALA contributes to the maintenance of normal blood cholesterol levels. The beneficial effect is obtained with a daily intake of 2g ALA.^4,5

Chia seeds are high in fibre

Fibre is one of the biggest nutritional reasons to include chia seeds in your diet. Around 28g of chia seeds provides approximately 10g of fibre, although the exact amount varies between products and food databases.

“One of the biggest nutritional advantages of chia seeds is their fibre content. Just two tablespoons, around 28g, provide approximately 10g of fibre, which is a third of the recommended daily intake for UK adults,” says Molly.^1,6 “Adding them to porridge, yoghurt or smoothies is a simple way to help increase your fibre intake without making major changes to your diet.” If you’re not used to eating much fibre, introduce chia seeds gradually and make sure you drink enough fluid.

Chia seeds provide plant-based protein

Chia seeds contain around 4–5g of protein per 28g serving. Protein is needed for normal growth and maintenance of the body, including muscles, so chia seeds can contribute to overall protein intake. They can be particularly useful when combined with other plant protein sources, such as nuts, seeds, pulses, soya products and wholegrains.

Although chia seeds contain all nine essential amino acids, they aren't especially protein-dense compared with foods such as tofu, beans, lentils or higher-protein dairy alternatives. Think of chia as one part of a varied diet rather than your main protein source.

Chia seeds provide iron

Chia seeds contain iron which contributes to normal cognitive function, as well as normal energy-yielding metabolism, oxygen transport and the normal function of the immune system.^5,7 Including a variety of iron-containing foods in your diet is particularly important because iron is an essential mineral that the body cannot produce.⁸

Chia seeds provide selenium

Chia seeds also contain selenium. Selenium contributes to the normal function of the immune system and normal thyroid function.^5,9 The amount of selenium in chia seeds can vary depending on factors including growing conditions, so check the nutritional information on the product you buy.

Chia seeds contain antioxidants

Chia seeds contain natural antioxidants, such as tocopherols, phytosterols, carotenoids and polyphenolic compounds.¹⁰ Antioxidants are compounds found in many plant foods.¹¹ Rather than viewing antioxidants as a reason to eat one particular 'superfood', it’s best to get a variety of plant foods in your diet. Fruit, vegetables, wholegrains, pulses, nuts and seeds can all contribute different plant compounds to your diet.

You may see chia seeds promoted as a food that can help you lose weight because they're high in fibre and protein. However, there isn't enough evidence to say that chia seeds themselves cause weight loss. Recent research has produced mixed findings – some studies found that chia consumption was associated with reductions in waist circumference but it did not significantly affect body weight or BMI.¹²

“One of the best things about chia seeds is how easy they are to incorporate into everyday meals," says Molly. "Their mild flavour makes them a versatile addition to overnight oats, yoghurt, smoothies and even homemade baking.” Try:

• sprinkling them over porridge or cereal

• adding them to yoghurt or overnight oats

• blending them into smoothies

• mixing them into homemade granola

• stirring them into soups or sauces as a thickener

• adding them to homemade energy bites

• making chia pudding

• using them in baking

• mixing them into jam

• using them as a plant-based egg replacement

From creamy breakfast puddings to indulgent chocolatey treats, chia seeds are surprisingly versatile. Make them the star of the show with our mango chia pudding or high-fibre Nutella-style chia pudding. Or try adding them to our Black Forest gateau pots or spiced apple, pear and berry breakfast crumble for another delicious way to enjoy them.

Tiny in size but big on versatility, chia seeds have plenty to offer. From their impressive nutritional profile to their effortless ability to slot into everything from breakfast bowls to bakes, these little seeds make it easy to add something extra to your everyday meals. Whether you’re already a chia seed convert or just discovering their potential, there are plenty of delicious ways to enjoy them.
