I'm going to do what another reviewer did and copy a review that was on Amazon which surgically breaks down the content of this book. You'll understand once you read it why I copied and pasted.
This is one of the deepest books I've ever read. It is dense. It is not an easy read. You have to take your time with it.
Crazily enough, it's still entertaining. Despite what a mental giant Robert H. Lustig is, he's still able to relate with normal people.
Once you're done reading however you will be a different person.
The man is intellectually honest. He tells you what studies are not completely proven. He constantly brings up correlation does not necessarily imply causation. He fact checks himself frequently. He admits what science does and doesn't know. He's thorough. He cares.
It makes you trust him. Which is great, because what he does tell you with near certainty is so important.
You'll understand exactly why you make yourself miserable with social media, processed food, and so many other vices once you're through with this book. You'll understand it so intimately you will find it difficult to ever engage in certain behaviors again. For months I've had Robert H. Lustig's voice in my head, where he's telling me exactly what I'm doing to my body with my choices.
More importantly, he tells you how to feel better without medication. His advice works. It should be taught in all schools. Family planning clinics should have free courses on this information.
To learn more, read this excellent review:
"I had the opportunity to review Dr. Lustig’s book and interview him before it was published. He is perhaps best known for his brilliant research into sugar and obesity. His previous book, “Fat Chance:” [which i read] was a New York Times Best Seller. Lustig is an emeritus professor of pediatrics in the division of endocrinology at the University of California, San Francisco, and a member of the Institute for Health Policy Studies.
His motivation for “writing the book began 30 years ago, while still a postdoctoral fellow in neuroscience at Rockefeller University."
There, he learned about the interaction between dopamine and serotonin in the brain. At the time, only basic correlational data existed, but there appeared to be a very specific interaction going on between these two neurochemicals.
The book discusses how many try to bolster their happiness through certain food choices [also drugs, alcohol and technology], but this actually does not work, and Lustig provides compelling arguments that the foods [and other items] you crave drive up dopamine and drive down serotonin. Rather, it’s experiences that make you happy. People can make you happy. You can make yourself happy. In his book, Lustig outlines a number of different strategies to become happier. Ultimately, the goal is [to increase] your serotonin,” he says. There are four ways to boost your serotonin, and they’re all free. They’re also things your grandmother likely told you to do. First and foremost is making human connections.
Social media generate dopamine, associated with pleasure, and hence can drive addiction. The main problem is that when dopamine goes up, serotonin goes down. So, online communication is actually a major causative factor of unhappiness. Lustig also elaborates on how companies — both food manufacturers and electronics companies — capitalize on the biology of dopamine versus serotonin to get us addicted to their products.
It’s important to realize that the dopamine (or reward-generating) pathway is the same no matter what your source of pleasure is. It can be a substance, such as nicotine, alcohol, heroin or junk food; or it can be behavior, such as internet surfing, shopping or pornography. The problem, in a nutshell, is that dopamine is an excitatory neurotransmitter, and in excess is neurotoxic. When dopamine is released, and the neuron on the other side accepts the signal, it can damage that neuron. Over time, excitatory neurotransmitters can cause cell death. To protect itself from damage, the postsynaptic neuron employs a self-protective mechanism — it downregulates its receptors.
By having fewer receptors, the dopamine cannot do as much damage. So, each time you get a “hit” or rush of dopamine, the number of receptors decrease. As a result, you need increasingly larger doses or “hits” to get the same rush. Eventually, you end up with tolerance, a state where even a large dose produces no effect. Once the neurons start to actually die off, you’re a full-blown addict. Serotonin, on the other hand, is not an excitatory neurotransmitter. When it acts on the serotonin-1a receptor (the “contentment” receptor), no damage occurs. Hence, happiness does not lead to addictive behavior. Keep in mind that dopamine downregulates serotonin, so it’s basically impossible to achieve happiness (related to serotonin) through pleasure-seeking behavior (related to dopamine).
One of the cheapest pleasures that stimulates dopamine is sugar. Many reach for sweet junk food when they feel down, thinking it’ll help them feel better, but neurochemical science reveals this simply cannot happen. Add the stress hormone cortisol to the mix, which downregulates the serotonin-1a receptor, and you have a recipe for both addiction and depression. That’s what we’re seeing throughout all of civilized society, not just in America, but around the world. There are three other ways, besides connecting, that boost serotonin and happiness. The remaining three of the four C’s are:
1. Contribute: Meaning the act of contributing to something greater than yourself; making a contribution to society. “You can get happiness and contentment from your job, but there are certain criteria that have to be met,” Lustig says. “Most people, unfortunately, have a boss who is not contributing to their happiness. The workplace is not usually the best place to achieve meaningful contentment.”
2. Cope: Lack of sleep, insufficient exercise and multitasking are all causes of unhappiness. Sleep is extremely important for healthy serotonin production. Here, avoiding exposure to electronic screens is important, as blue light inhibits melatonin production, thereby making sleep more elusive. Electronics will also disrupt your sleep and deteriorate your health by exposing you to unnecessary microwaves, discussed in this recent article on depression.
3. Cook: If you cook, you’re likely going to increase your tryptophan, reduce your refined sugar intake, and increase your omega-3 fats (anti-inflammatory) and fiber. Overall, this will result in improved gut health, which has tremendous impact on your mood and mental health.
How do you boost systemic tryptophan? One of the keys is to eat real food, and to make sure you include high-tryptophan foods, the highest of which is egg whites. You also need omega-3 fatty acids, especially DHA, which is a component of every cell in your body. More than 90 percent of the omega-3 fat found in brain tissue is DHA.
The problem, of course, is that when we took the fat out of the food, we took ALL the fat out of the food. It’s been a real chore to get the medical cognoscenti to turn around on this. I do want to do a shout out to the American Heart Association, because they have now debunked their long-standing cholesterol-fat hypothesis. They now recognize that saturated fat was not the demon they made it out to be, and that there are seven classes of fats, and that you actually have to consume omega-3s. You have to consume monounsaturated fats. In fact, you do have to consume some saturated fat because it’s a major component of membranes.
Processed fructose, mostly in the form of corn syrup, has become a major contributor to the $3 trillion health care budget in the United States, and there’s clear data linking sugar consumption to de novo lipogenesis — a disease process associated with fat accumulation in the liver, causing insulin resistance, hyperinsulinemia, metabolic syndrome and associated diseases. That includes Type 2 diabetes, hypertension, lipid problems, cardiovascular disease, cancer and dementia.
In the past, people had a much better understanding of happiness and pleasure. Lustig’s book describes how these terms have been purposely conflated and confused by businesses and governments because it helped sales. To turn the trends of addiction around, you have to understand the difference between the two.
So, what’s the difference between pleasure and happiness? There are seven differences: Pleasure is visceral; happiness is ethereal. Pleasure is short-term; happiness is long-term. Pleasure is usually achieved alone; happiness is usually achieved in social groupings. Pleasure is taking; happiness is giving. Pleasure can be achieved with substances; happiness cannot be achieved with substances. The extremes of pleasure all lead to addiction, whereas there is no such thing as being addicted to happiness. Finally, pleasure is dopamine and happiness is serotonin."
