In the first of two episodes on food and grief, Emily Thomas explores how food can help us navigate through the darkest of times - the days, weeks, and even years following the death of someone we loved. In times of loss, should we use food to remember the dead or to reconnect with them? A neurologist explains the science behind grief and appetite, and people who've been recently bereaved talk about the foods and eating rituals that have helped them through it. (Photo: A raw onion.
