Answer 2

You can pass the list to the view model using Html.hiddenfor each list item.

, for (foreach ). :

@for (var i = 0; i < Model.Nutrients.Count(); i++) 
{
  // This ensures that the list of nutrients is passed in the view model back to the controller
  @Html.HiddenFor(m => m.Nutrients[i].Name);
  @Html.HiddenFor(m => m.Nutrients[i].Id);
}
