This is focused on the design and evaluation of drug delivery systems that release a bioactive agent at a rhythm matching the biological requirements of the treatment of a given disease [ 53 ]. Muslims take up the ecological challenge Few of them have taken into account the chrononutritional properties responsible for the effectiveness of such compounds. These include, but are not limited to, chronobiological, immunomodulatory, neuroendocrine, and antioxidant activities Figure 1. Around this time of year, much of the world is advancing their clocks by one hour to make efficient use of seasonal daylight. Finally, in the most significant phenol in red wine, trans-resveratrol, was shown to prevent carcinogenesis in mice [ 68 ].

This prolonged feeding period more time each day in which food is being consumed instigates rapid changes in daily gene expression and produces multiple adverse metabolic consequences, including fat gain, insulin resistance, and impaired lipid regulation, increasing fat deposition in the liver 1. In particular, it is a signal of darkness that encodes time of day and length of day information for the brain chrononutririon 17 ].

The mechanism is via enhancement of the brain serotonin functions that are involved in the adaptation to stress []. We now understand that the increased neuronal and metabolic activity of the brain during exercise drive increases in blood flow to it.

Particularly noteworthy was that not only the substantial amount of melatonin, serotonin [ 78 ], and tryptophan [ 80 ] contained in these Jerte Valley cherries, but also the timing of the meal, were critical to achieving the beneficial effects of these dietary interventions.

They have been linked to reductions in the risk chronlnutrition major oxidative stress-induced diseases [ 13 ]. Antioxidant systems deteriorate during aging.
