What does the word pulse mean in the book of Daniel?

The Word 'pulse' occurs 2 times in the King James Bible in Daniel 1:12 & 16. Pulse is also suggested in 2 Samuel 17:28.

Pulse is the English Word for the Hebrew "zeroa", which is generally vegetables, mostly raw, although many are dried and put into flour for bread.

"Zeroa" is also a plural noun meaning "vegetables, herbs, vegetable food, such as is eaten in a half fast; opposed to flesh and more delicate food."

Jewish answer:

The Hebrew Word refers exclusively to legumes, seeds and the like - not to vegetables, or flour or bread of any kind.
