Cooking food and purity.(Meat purity idea also)

Now we have trees with purity, can we add it so cooking a 25/25/25/25 bit of meat with 15/55/15/15 twigs from a tree will yeild 20/40/20/20 cooked meat, so on and so forth ?
Has this even been considered that wood purity used why cooked should come into the calculation of the final product ? Most of all in Times were getting high purity is very hard, most of all in meat produce.
This would also help to contribute towards a wider range of cooked foods used.
PS: Secondary idea for meat purity.
How about the idea that you can let your meat hang on a drying rack for X period of time to increase its elemental composition towards the value of the materials (wood) to build the frame?
