While the popularity of chia seeds has recently grown, the tiny seeds have been around for thousands of years and are believed to have originated in Central America, where they were eaten by the Aztecs.
Effective Method to Get the Most Out of Chia Seeds
Chia seeds are a popular superfood but consumers may not be getting the most benefit possible out of them, said the team from the University of Adelaide in Australia.

“Chia seeds contain healthy fats, antioxidants and dietary fibre but there isn’t a lot of research into how the composition of these seeds interact with gut microflora, which help to digest food,” said Rachel Burton, Professor from the University’s School of Agriculture, Food, and Wine.
“Through this research, we discovered that different preparation methods influenced the nutritional benefits gained from the seeds and grinding them up delivered more nutrients than consuming them whole.”
To carry out this research, gut microbes from pigs were exposed to different forms of chia seeds, including whole seeds and seeds that had been ground into a meal.
The samples were incubated for 70 hours while a special robotic machine measured the gas released over this time, simulating the digestion process.
Best Way to Consume Chia Seeds for Optimal Dietary Fiber Benefits
“What we found was that when the seeds were ground down, they produced more beneficial metabolites or fuel that could then be used to renew gut cells,” said the University’s Dr. James Cowley from the School of Agriculture, Food and Wine.
“This shows the benefits of eating chia seeds could be enhanced if the nutlets are ground, improving access to key nutrients such as dietary fibre.”
The findings, including a detailed chemical analysis of the composition of chia seeds, have been published in the journal Food & Function.
“There is a lot of emerging research that show gut microbes in the digestive system influence a huge range of conditions including depression and anxiety. Consuming ground chia seeds may potentially shift populations of gut microbes and affect progression of these conditions, however more research needs to be conducted in this area,” said Cowley.
