Researchers in Canada say that the supposed health benefits of eating fish are over-stated and are putting pressure on wild fish. Fish oils are promoted for heart health, but results are mixed. Vegetarians don’t have an increased risk of heart disease (in fact, they have a 25 per cent lower risk). Safer, healthier sources of omega-3s include flaxseed oil and algal supplements. Farley Mowat, co-author of the study, said: “The damage we have already done to life in the oceans is a prime example of our idiocy, and a last warning that we had better change our ways”.
