במזון שתי סעודות לעירוב (see also Tractate Eruvin, Chapter 8, Mishnah 2) – A person who wants to walk more than two-thousand cubits on Shabbat makes a joining of borders/ עירובי תחומין and places the food for two [Sabbath] meals in the place where he desires that he will establish his Eruv, and he walks from the place of his Eruv and beyond [another] two-thousand cubits. And this is six eggs according to Maimonides and eight eggs according to my Rabbis/Teachers.

All kinds of food can combine with one another: To make up the quantity of half a peras in order to render the body unfit One who eats half of a peras (the equivalent of two eggs) of unclean food, cannot eat terumah until the evening. The food “renders his body unfit” to eat holy food. Different types of unclean food can join to create this minimum amount.
