commerce tied to these issues, expecting firm answers any
time soon may be wishful thinking, as the research is sure to
be mired in the eternal conflict between corporate interest
and scientific inquiry. But by opting for organic produce we
may be able to at least stack the odds in our own favor as
we await greater clarity.
Engage in Brief Periods of Fasting
New research from the Buck Institute for Research on
Aging suggests that fasting is able to “tune” synaptic
activity, giving these high-activity connection points a rest
as an energy conservation measure. When researchers
observed the neurons of fruit fly larvae in a fasted state, the
amount of neurotransmitters released decreased
dramatically, which essentially cleaned up the synaptic
gaps. This is positive because excess neurotransmitters left
to linger in the synaptic gaps can generate damage-causing
free radicals. Fasting may therefore help limit unwanted
oxidative damage in the brain (alongside its ability to reduce
the brain’s dependency on glucose).^43 Chapter 10 revisits
practical and safe fasting protocols.
Avoid Excessive Stimulation
Multiple systems are involved in mediating sensory
input. When our senses become overloaded, this can
substantially diminish our executive function. This is
perfectly illustrated by what happens when we watch a
movie. The sights and sounds completely envelop us and
we feel immersed in the universe of the film. This occurs
