The relationship between our diet and sleep is bi-directional;
i.e. sleep impacts diet and diet impacts sleep. Therefore, we can
examine the impact of sleep timing, duration and other dimensions
on our dietary intake. And then also examine the impat of both
overall diet and specific nutrients on improving/worsening
sleep.
The is clear evidence of distinct, acute effects of restricted
sleep time on food preferences, eating behaviour, energy intake,
and our underlying metabolic physiology.
When it comes to the ability of certain foods or nutrients to
improve sleep, often many claims are based on weak evidence or
mechanistic reasoning. But there is evidence showing some impacts
of certain compounds to either positively or negatively impact
sleep.
So what is the accurate way to look at this bi-directional
relationship? In this episode, Greg Potter, PhD discusses the
evidence to date. Dr. Potter received his PhD from the University
of Leeds, where his research focused on circadian rhythms, sleep,
nutrition, and metabolism.
