If you click the fridge, you will se a message in the top of the menu bar. It will tell you how much food they have. They seem to be most happy, when they have 1000 or more.

MickyTeddy asked:

How do you how much food your little peeps have??
Saves me just buying or waiting for an e mail asking?!!

Hi Micky, Click the top of the fridge and it will show you exactly how many food units your little peeps have. It's good to buy the food when it's on sale whether they need it or not. I try to keep 1000 or more food units in their fridge.

Thanks!!
I had in fact just worked it out!!!

Click on the refrigerator and it will tell you how much food is available. This does not include food you have bought but is still in your tool tray. Once you put a bag of groceries on the table, its contents are added to the grocery total, even if the peeps have not put them away yet.

FWIW, I checked, and the other food-related actions (apart from preparing a meal) don't reduce the amount of stored food. These include feeding the fish, barbecuing, making breakfast, or even (with a kitchen-related job) working on a career,

The BBQ does drop it by 3. Not a lot, but it does drop it, but it does also increase their fed bar. I find I use the BBQ to feed my 55+ family members when there are no kids as they are too slow to prepare meals and it's a fast way of getting them fed.

I also noticed today that when one of the peeps throws out old food there is no change in the amount in the food units. Wish it worked that way for real!

Oops! So it does!

I must have miscounted.

It was easy for me to check. I was on 1406 food, and dropped the two parents on there (as they're 58 & 56 and needing feeding), and got 1400, so if I got that wrong there would be something wrong!
