Frequently Asked Questions (FAQs)
1. Which fish is sustainably sourced?
Organic farmed salmon and trout are a good alternative to wild-caught and cause significantly less pollution than regular fish farms. Vegetarian fish such as tilapia or carp are greener still as they don't require feeding with fish meal – one of the biggest contributors to the decline in wild fish stocks.
2. Are fish oil supplements ethical?
While taking fish oil is quite harmless (apparently in both a health positive and negative sense), the industry does significantly damage the environment. According to Greenberg's book, fish oil is customarily extracted from large quantities of forage or bait fish such as anchovies and krill.
3. Is cod liver oil sustainable?
This is widely considered to be one of the world's most sustainable sources of cod. To ensure that these species of fish continue to thrive, Möller uses only the livers from cod caught from the Norwegian fisheries certified by the Marine Stewardship Council.
4. What is the controversy about fish oil?
New research finds that taking omega-3 supplements is associated with an increased risk of atrial fibrillation in people with a high risk of, or existing, heart disease. Experts say while omega-3s are essential for health, the relationship between using these supplements and heart health is complicated.
