Chia seed

Chia seeds are the tiny seeds of the Salvia hispanica plant, a member of the mint family, native to Mexico and Guatemala. They are harvested from the plant and typically sold whole and dried, requiring no further processing for consumption.

Chia seeds are often added to foods for their nutritional content and texture. They can absorb liquid and form a gel, making them useful as a thickener in puddings, yoghurts, and smoothies. They are also frequently incorporated into baked goods like bread and crackers, as well as porridges and breakfast cereals.

Chia seeds are not classified as a food additive in the UK and are therefore not listed on the Register of Food Additive Authorisations. They are a source of fibre, protein, and omega-3 fatty acids. The European Food Safety Authority (EFSA) has evaluated chia seeds in the context of novel foods, and they are authorised for use in the EU and UK. Evidence suggests they can contribute to a healthy diet, but like all foods, excessive consumption may lead to digestive discomfort due to their high fibre content.
