Mishneh Torah — Negative Mitzvot מצוות לא תעשה, Chapter 137

שלא תאכל חללה קודש, לא תרומות ולא חזה ושוק, שנאמר "ובת כוהן--כי תהיה, לאיש זר" (ויקרא כב,יב).

For a chalalah not to partake of consecrated foods, neither terumah, nor the breast and the shankbone [given to the priest], as [Leviticus 22:12] states: "When a priest's daughter marries an unauthorized person, she shall not eat [from the sacred, elevated gifts]."
