The traditional foods of Daeboreum have a lot of connections with superstition.

People drink cold 'Guibargi Wine' in the morning, believing one will only hear good news all year round and will hear better.

The nutcracking that is described in the book, <Dongguk-sesigi (in Korean: 동국세시기)> has been widely spread not only in Korea but also in China and Japan, and it is being performed on New Year's Day, too.

There is also a custom of eating ogokbap (오곡밥 or chalbap, 찰밥) and yakbap (약밥) around Daeboreum.
Yakbap is made by steaming glutinous rice and mixing jujube, chestnut, pine nuts, oil, honey, and soy sauce together.
In South Jeolla Province (전라남도), people steamed it with a 'siru' (시루) steamer and gave it to the castellan, so it is called 'castellan rice' or 'siru rice'.

People eat a lot of dinner early on the 14th and early on the morning of the 15th, which means to be diligent throughout the year.
Also it is said that it is better to eat the food of the neighbors.
This is called hometown rice (세성받이밥).
If you make dinner late, you may lose a dinner to the invited neighbors, so people made an early dinner and invite the neighbors from 2 pm.
Also in <Dongguksesigi (in Korean: 동국세시기)>, it is  described about a similar tradition of 'Baekgaban' in Jeollanam-do – children go to get rice in the morning from the neighbors in Daeboreum.
Gyeongnam has the same tradition.
They believe it is good for their health.

There is a tradition of eating a selection of certain seasoned vegetables referred to as boreum namul (보름 나물, or mugeun namul 묵은 나물) as well as bokssam (복쌈): Dishes made from dried vegetables, left over from the previous year (e.g. pumpkin leaves, radish greens, eggplant, mushrooms, ferns) are believed to enable one to cope with the heat in the next summer, when eaten on Daeboreum.
Eating bokssam, which is rice wrapped in leafy vegetables, is supposed to bring luck (bok, 복, 福).

In Jeollanam-do, the barley rice is put into a bowl with herbs and placed on a straw or a wall to give to the crow.
There is a similar report in Jeonbuk and Chungbuk.
The crow is now an ominous bird, but in the past, it was a sacred bird, also a symbol of the sun. '
crow's sacrifice' and 'crow's rice' are  described in Samguk Yusa.
