In this fully updated edition of his 2013 bestseller Toxic Oil, David Gillespie reviews the latest research from this rapidly evolving field linking seed oils to a host of diseases, including cancer.

Over the past century, manufactured seed oils - canola, sunflower and rice bran oil, among others - have systematically replaced saturated fats in our diet. Despite nutrition guidelines stating this is a good thing, our rates of obesity, diabetes and heart disease are soaring. In fact, recent findings suggest that animal fats are not the villains we once thought them to be.

As most processed foods - from breads and crackers to mayonnaise and pesto - contain seed oils, David shows us how to identify these toxic products and make healthier choices at the supermarket. He tells us which brands to avoid, which to enjoy - and how to create seed-oil free versions of favourite foods at home.
