This guide looks at the science behind health claims for fish and unearths the research that the fish industry would rather ignore - research which clearly shows that plant-based oils are much safer and healthier. It explains what omega-3 fats are, why they're important and recommends sources other than fish. It reveals precisely what toxins are present in fish and how harmful they can be. It explains why public health policies promoting oily fish are misplaced and how they effectively undermine health promotion. This guide will leave you in no doubt - fish is not a health food.
