0:00.0	Welcome to Zoe, science and nutrition, where world-leading scientists explain how their research can improve your health. Seed oils are in everything. You'll recognize them as
0:18.4	sunflower oil, soybean or canola, that's rape seed in the UK. They're in our snacks, our restaurants and
0:26.0	our pantries. They're inexpensive. They have a neutral taste and a high smoke point
0:30.9	which makes them great for frying. But many people think seed oils are
