Functional foods are part of the continuum of products that individuals may consume to improve their health
and/or contribute to reducing their disease burden. By these networks, various parameters can be calculated to quantitatively
characterize the complex and nonlinear physiological effects of wireless communication network and the metabolic
networks formed around the central metabolic pathways in vivo. It is concluded that network methods, particularly the
metabolic network and intercellular wireless network methods play an important role in quantitative evaluation of functional
foods in vivo using only a few milliliters of peripheral blood from volunteers.
