I think the look of food is important in hospital - a lot of patients need to eat more but feel too sick to. Food that looks awful discourages patients from eating it even more. I've usually been on gastro wards - the food sucked and they couldn't manage to cater to special dietary needs. There were always special items on the menu - vegetarian, "soft" food, etc. but what ended up being brought often varied a lot from what patients had selected. I think it just varies a lot from hospital to hospital.I've seen some of the photographs that have been published over the last day or so and they don't look good but food doesn't always photograph well. I can think of ready meals I have bought from the likes of Waitrose that look fantastic in the carefully set up photo on the packaging but reality is somewhat less flattering.
So that's my experience. Maybe I have just been lucky on the above occasions as I was in the specialist gastro ward where they realised the importance of getting their patients to eat.
