Michael Mosley gets his flax fix, as he finds out how flax seeds, also known as linseeds, can protect your heart, reduce your blood sugar levels, and might even keep your skin feeling smooth and hydrated! With the help of Dr Grant Pierce from the University of Manitoba in Canada, Michael learns about the key components of flaxseed, including alpha-linolenic acid, and how they contribute to its array of impressive benefits. Through his research, Grant has demonstrated that daily flaxseed can lower your blood pressure and cholesterol, reducing your chance of a heart attack or stroke by a remarkable 50%! Meanwhile, our volunteer Rena finds flaxseed a welcome addition to her diet. Series Producer: Nija Dalal-Small Editor: Zoë Heron A BBC Studios production for BBC Sounds / BBC Radio 4.
