Gourmet Cells (グルメ細胞 Gurume Saibou) are specialized cells first discovered and harvested from Gourmet Jellyfish by the "Bishokushin" Acacia 605 years ago. The cells have excellent regenerative and strength-enhancing qualities. When implanted into the cells of another living thing, they can enhance its qualities and abilities in various ways. For instance, when Gourmet Cells are implanted into ingredients, their flavors improve producing more delicious versions of the originals though this may also have the effect of making the ingredient more powerful and difficult to capture as well.
When a human successfully adapts Gourmet Cells into their body they gain overwhelming life force and strength, creating a super human. An individual's Gourmet Cells increase in power when they consume delicious foods that suit them and the 'tastes' of their gourmet cells, causing the cells to "evolve"; this enhances the strength of the user and their abilities. Gourmet cells can also evolve as a response to harsh new environments, instantly creating adaptations which allow the user to survive. Training one's Gourmet Cells to adapt to a variety of such environments is an integral part of training to survive in the Gourmet World.
Implanting Gourmet Cells in one's body carries risks, however. If an individual's body is not compatible with the cells at the implantation stage they may gain no power, or even die. Gourmet Cells have very high energy demands, so individuals must consume frequent large amounts of delicious food, lest the cells begin uncontrollably devouring the their body at the cellular level.
Because of the incredible and wide-ranging abilities of Gourmet Cells, and in particular their ability to increase fighting strength, many prominent Bishokuya, Saiseiya, chefs, IGO members, and even criminals have them. Many of these, such as the members of the Bishokukai, seek out new and rare ingredients specifically to increase their fighting strength.
But the biggest advantage Gourmet Cells can afford is Appetite Energy. It is pure cellular energy emitted created by a person or animal in order to defeat its prey. The energy is not created by normal appetite, but a hunger to get delicious food.
