What is the recommended daily intake of EPA and DHA according to WHO/FAO, and is there a difference for pregnant or lactating women?
-The WHO/FAO recommends a daily intake of 250 mg of EPA and DHA for adults. For pregnant or lactating women, the daily intake should be increased to 300 mg.
How are omega-3 fatty acids incorporated into meat, eggs, and dairy products, and what is the challenge with using fish oil?
-Omega-3 fatty acids are incorporated into meat, eggs, and dairy products by using algae, fish, or fish oil as feed for laying hens, dairy cattle, and bovine farms. The challenge with using fish oil is its potential effect on product stability, odor, and taste, which can be mitigated with technologies like microencapsulation, deodorization, and the addition of antioxidants.
What is the projected growth rate and market value for long chain omega-3 fortified food products by 2022?
-The market for long chain omega-3 fortified food products is projected to grow at nearly 14 percent per annum and is predicted to exceed $25 billion USD by 2022.
