Sugar, seed oils, and avoiding sickness: your health questions answered

We asked for your questions on getting healthy in 2025 and you
delivered. In the first episode of our listener questions special,
Madeleine Finlay tells Ian Sample what she has uncovered about the
scientifically proven ways to cut down on sugar, the truth behind
the panic over seed oils, and why it is that some of us seem to
have bullet proof immune systems, while others succumb to every bug
they encounter. With contributions from Wendy Wood, provost
professor emerita of psychology and business at USC Dornsife, John
Trowsdale, emeritus professor of immunology at the University of
Cambridge and Katherine Appleton, professor of psychology at
Bournemouth University. Help support our independent journalism at
