Rich in protein, omega 3 and essential minerals, it promotes digestion, prevents cardiovascular disease and is anti-inflammatory. Chia (Salvia hispanica) is a species of sage native to Mexico and Guatemala that gave its name to the Mexican state of Chiapas (waters / river of chia). This plant was cultivated by the Aztecs and Mayas who already knew the peculiarities of this plant. Chia seeds were then the third source of plant food in their diet after corn and bean varieties. Chia seeds are rich in omega-3 essential fatty acids (15-17% in the form of alpha-linolenic acid - ALA). 5 g of chia seeds cover 45% of the NRN (daily nutritional guidelines) in omega-3. They have a high dietary fibre content which gives them a great satiating power when hydrated. Indeed, their richness in mucilage makes them increase considerably in volume, to form a gel, when immersed in water. Chia seeds are excellent for sportsmen and women because of the protein they contain (about 22 g per 100 g). Finally, chia seeds do not contain gluten or cholesterol.
