Sehdeva ate his father’s brain, literally!

When Pandu, the father of the Pandavas, was about to die, he wished for his sons to partake of his brain so that they inherit his wisdom and knowledge. Only Sahadeva paid heed, though; it is said that with the first bite of his father’s brain, he gained knowledge of all that had happened in the universe. With the second he gained knowledge of the present happenings, and with the third he came to know of all that would occur in the future.
