By: Michael Moss


In the world of processed foods, there lies a hidden secret: addiction. They manipulate our brains, making us crave more and more of their products. The book ‘Hooked: Food, Free Will, and How the Food Giants Exploit Our Addictions’ by Michael Moss offers an eye-opening insight into how and why we become addicted to sugar, salt, and fat. The summary delves into our evolutionary biology, the neurological pathways that keep us hooked, how our childhood memories impact our eating habits, and the tactics used by the processed food industry. Get ready to explore the fascinating psychology and science behind food addiction, and how it affects our lives in countless ways.

Appetite Control and Food Addiction

Appetite is controlled by the brain, not the stomach, and food addiction stems from the speed at which substances affect the brain.

For a long time, it was believed that our appetites were governed by our stomachs. However, recent research has shown that it is our brains that control our appetite, not our stomachs. Evidence for this is seen in bariatric surgery patients whose stomachs are reduced, yet their appetite returns within a year. This implies that appetite control is located in the brain. The return of appetite causes some patients to eat until their tiny stomachs become engorged or rupture. It highlights the fact that addiction is a brain condition—the quicker a substance can enter the bloodstream and reach the brain, the more addictive it is. Sugar, salt, and fat, the necessary components of processed foods, affect brain chemistry just half a second after consumption. In comparison, nicotine takes ten seconds to impact the brain, showing how fast sugar works on our neurons. This revelation firmly supports the idea that food can indeed be addictive.

Childhood Eating Habits Affect Adult Life

Memories of eating processed foods in childhood make it easier for adults to crave and remember these foods. This is due to the creation of neural pathways in the brain that associate the experience with pleasure and comfort. The more one eats processed foods as a child, the stronger these pathways become, leading to an increased likelihood of craving these foods in the future. Therefore, it’s crucial to establish healthy eating habits early on to prevent long-term negative effects.

The Evolutionary Biology of Food Cravings

The reason we find salty snacks, processed foods, and high-calorie meals so irresistible lies in our evolutionary biology. Our ancestors’ ability to tolerate a variety of foods served them well, but today’s dizzying range of options encourages overeating. Furthermore, our stomachs have evolved to recognize and enjoy high-calorie foods, signaling to our brains that these foods are good. This adaptation is still at work, explaining why we’re drawn to foods like pizza and Oreos, purely because they’re so dense in calories.
