Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Flax and chia seeds (22.5 grams of flax seeds and 22.5 grams of chia seeds containing ~10.25 grams of ALA) in a population following a whole food plant-based diet.

The flax and chia seeds will be incorporated daily (45g/day) into participants existing diets by mixing or adding to meals i.e. sprinkled on oats for 8 weeks.

Adherence will be monitored by asking participants to return all seeds which were not consumed during the 8 week intervention.

Both groups will be asked to continue eating their existing low fat (<20%) whole food plant-based diets. Additionally, both groups will also complete a validated online 24 hour diet recall to measure adherence to the intervention.
