Trail of Crumbs
Enchantment
When this enchantment enters, create a Food token. (It's an artifact with "
, 
, Sacrifice this token: You gain 3 life.")
Whenever you sacrifice a Food, you may pay . If you do, look at the top two cards of your library. You may reveal a permanent card from among them and put it into your hand. Put the rest on the bottom of your library in any order.

While resolving the second triggered ability, you can't pay multiple times to look at more cards.
A permanent card is an artifact, creature, enchantment, land, or planeswalker card.
Whatever you do, don't eat the delicious cards.
If an effect refers to a Food, it means any Food artifact, not just a Food artifact token. For example, you can sacrifice Tough Cookie (an Artifact Creature — Food Golem) to activate Maraleaf Rider's ability (an ability with "Sacrifice a Food" in its cost).
Food is an artifact type. Even though it appears on some creatures, it's never a creature type.
You can't sacrifice a Food to pay multiple costs. For example, you can't sacrifice a Food token to activate its own ability and also to activate Maraleaf Rider's ability.
