Can "pleisiur" be used to talk about the pleasure of eating food? "An pleisiur na bia"
"The pleasure of eating food" would be an pléisiúr a bheith ag ithe bia.
I'm not quite sure what it would mean, but "The pleasure of food" would be pléisiúr an bhia - no leading an, because the one in the middle makes the whole phrase positive, and an bhia because bia is a masculine noun, with bia as it's singular genitive form.
For food, sásamh might be more appropriate, but the same argument could be made about English.
