Chia Seeds
Small seeds that absorb many times their weight in liquid, providing exceptional fibre and the highest plant omega-3 content of any common food.
What Chia Seeds Provide
Chia seeds are notable for two things: an unusually high fibre content and the highest concentration of omega-3 ALA of any commonly eaten food. They can absorb roughly ten times their weight in water, forming a gel that is used to thicken puddings and to replace eggs in some recipes. They also supply calcium, magnesium, and phosphorus.
Nutrition Highlights
Omega-3 ALA
An ounce of chia seeds provides about 5 g of omega-3 ALA — more per gram than flax seeds. ALA is an essential fatty acid and a precursor to longer-chain omega-3, although the body converts only a small fraction.
Fibre
Roughly 9.8 g of fibre per ounce, which is close to a third of the daily requirement. Most of this is soluble fibre, which forms a gel in the gut and may support digestive regularity and feelings of fullness.
Calcium and Magnesium
Chia supplies about 179 mg of calcium and 95 mg of magnesium per ounce. Calcium supports bone maintenance, and magnesium contributes to normal muscle and nerve function.
Phosphorus and Protein
Around 244 mg of phosphorus and 4.7 g of protein per ounce. Phosphorus is a component of bone mineral and is involved in energy metabolism.
How to Include Chia Seeds in a Balanced Diet
- Stirred into yogurt or overnight oats.
- Made into chia pudding with milk and fruit.
- Whisked into salad dressings as a thickener.
- Added to smoothies for fibre and omega-3.
- Used as an egg substitute in baking (1 tbsp chia + 3 tbsp water).
Who Might Want to Watch Portions
Because chia absorbs large amounts of liquid, eating a dry handful without enough fluid can cause discomfort or, rarely, a blockage — always take chia with plenty of water. People on blood-thinning medication should note that chia is high in ALA and keep intake consistent. Introduce chia gradually to avoid bloating.
