Dopamine is the “reward” neurotransmitter that tells our
brains we want more; yet every substance or behavior that releases dopamine in
the extreme leads to addiction. Serotonin is the “contentment” neurotransmitter
that tells our brains we don’t need any more; yet its deficiency leads to
depression. Ideally, both are in optimal supply. Yet dopamine evolved to
overwhelm serotonin—because our ancestors were more likely to survive if they
were constantly motivated—with the result that constant desire can chemically
destroy our ability to feel happiness, while sending us down the slippery slope
to addiction. In the last forty years, government legislation and subsidies
have promoted ever-available temptation (sugar, drugs, social media, porn)
combined with constant stress (work, home, money, Internet), with the end
result of an unprecedented epidemic of addiction, anxiety, depression, and
chronic disease. And with the advent of neuromarketing, corporate America has
successfully imprisoned us in an endless loop of desire and consumption from
which there is no obvious escape.
With his customary wit and incisiveness, Lustig not only
reveals the science that drives these states of mind, he points his finger
directly at the corporations that helped create this mess, and the government
actors who facilitated it, and he offers solutions we can all use in the
pursuit of happiness, even in the face of overwhelming opposition. Always
fearless and provocative, Lustig marshals a call to action, with seminal
implications for our health, our well-being, and our culture.
Review: I was eager to read this book after listening to Lustig’s lecture, Sugar: The Bitter Truth, given ad part of the Series: UCSF Mini Medical School for the Public, in 2009. I found his work intriguing and enlightening.
This book further explored the issue of sugar in our diet,
but tied it to the larger issue – how corporations use our brain chemistry to
modify our behaviors and entice us to buy their products. Lustig takes us through
the two separate pathways in our brain – Dopamine (Pleasure) and Serotonin
(Happiness), explaining how each is vital to our life, but can also be used to
make us want things that aren’t good for us.
It’s a convoluted subject, making the narrative seem repetitive
at time – but it’s required to explain the topic properly. The text has more
pop-culture slang and jargon than one usually finds in science texts. It was a
bit distracting, as if Lustig was trying to make it “down-to-earth”. But it
didn’t. Despite this, I have recommended
this book to several people and will continue. It’s an important idea to
consider!
