DH has purchased a 1970s dinner service. We already have plenty of crockery but it's made up of the remnants of about 5 dinner sets. All of our dinner sets have larger plates than the 1970s one. This got me thinking is that why most recipes that say serve 4 often I only get 3 out of because the plate looks half empty. So I used the 1970s one and a 4 portion recipe did indeed fill 4 plates. So maybe a return to smaller dinner plates would help people reduce portion size and help the obesity problems
I will add that as a child we always had bread and butter on the table if we wanted it alongside our meal which doesn't seem to happen now unless it's garlic bread. Does our minds trick us into feeling full if we see a full plate and think we are still hungry if the plate isn't full?
