Participants will be instructed by clinical coordinators to integrate the products (2 sachets of seeds, 1 salad dressing) into their daily meals and to avoid other dietary sources of n-3 fatty acids, such as flax, chia, camelina, krill and fish products. Participants will be given activity monitors to wear during the intervention periods. Participants will be required to eat one sachet of hulled seeds in the morning and one in the evening, and to consume the dressing throughout the day, for each 4 week treatment period.
