Why do some foods seem irresistible? The packaged goods industry is notorious for adding ingredients like sugar, fat and salt that add to the “crave factor,” get us addicted to those foods, and fill us with antinutrients.
Understanding why we crave specific foods and how our brains respond to these cravings can help us manage them more effectively. This article provides information on the science behind cravings, the various triggers that promote cravings, and how following the principles of Nature’s pHarmacy® can help you manage and avoid cravings, while making healthier choices and avoiding immune burden.
The “Crave Factor” and Processed Foods
Dr. Jaffe talks about the “crave factor,” to explain how the processed food industry deliberately engineers foods to be more “crave-worthy.” By enhancing foods with higher levels of salt, fat, and sugar, manufacturers create products that are difficult to resist. These hyper-palatable foods overstimulate the brain’s reward system, leading to stronger cravings, in a cyclical loop. The more processed foods we eat, the more we crave them. The food industry’s ability to exploit this biological response has led to a surge in the consumption of ultra-processed foods, contributing to widespread issues like overeating, poor dietary habits, and a variety of preventable diseases.
The Science of Cravings
Cravings are often driven by complex biochemical processes that take place in the body. Several hormones and neurotransmitters play a key role in why we feel compelled to eat certain foods.
Hormonal Influences
One of the primary drivers of cravings is the interaction between hormones like ghrelin, leptin, and dopamine:
- Ghrelin, often called the “hunger hormone,” signals to the brain when the body needs food. Elevated ghrelin levels can intensify cravings, especially for high-calorie foods.
- Leptin is responsible for signaling fullness and satiety. However, when leptin resistance occurs—commonly seen in individuals with obesity—the brain doesn’t receive accurate signals to stop eating, leading to persistent cravings even after consuming enough calories.
- Dopamine, a neurotransmitter linked to the brain’s reward system, plays a significant role in why we often crave sugary, fatty, or salty foods. When we consume these foods, dopamine is released, creating a feeling of pleasure. This reinforces the behavior, making us more likely to seek out the same foods when we want that rewarding feeling.
Nutrient Deficiencies
Sometimes, cravings are a result of the body’s attempt to correct nutrient imbalances. For example, craving chocolate could signal a magnesium deficiency, while a strong desire for red meat may indicate low iron levels. The body, in its wisdom, drives us to seek out foods that it believes will restore balance. Unfortunately, with most modern diets, this doesn’t always lead to the healthiest choices.
Mental Triggers of Cravings
While physical factors like hormones and nutrient deficiencies play a role, cravings are often influenced by mental and emotional triggers. Stress, boredom, and habit can all drive us to reach for foods, even when we’re not physically hungry.
Stress and Emotional Eating
One of the most common mental triggers of cravings is stress. When we’re under stress, the body releases cortisol, a hormone that can increase appetite, particularly for foods high in sugar and fat. This is why stress often leads to emotional eating, where food becomes a coping mechanism. Comfort foods, such as sweets or high-carb snacks, offer a temporary escape, soothing negative emotions like anxiety or sadness.
Over time, this emotional reliance on food can become a cycle, where cravings arise as soon as stress hits. Recognizing this pattern is the first step toward breaking it.
Boredom and Distraction
Cravings can also stem from boredom or the need for distraction. How often have you found yourself reaching for snacks while watching TV, working from home, or mindlessly scrolling through your phone? In these moments, food becomes less about nourishment and more about occupying time or providing a temporary escape from the mundane.
The act of eating itself can offer a brief break from boredom, but it doesn’t address the underlying issue. Identifying activities that offer genuine engagement or fulfillment can reduce these types of cravings.
Habitual Cravings
Sometimes, cravings are simply a product of habit. If you’re used to having dessert after dinner every night or always grabbing a snack while watching your favorite show, your brain begins to associate certain times or activities with food. These habitual cravings are conditioned responses, triggered by routine rather than actual hunger.
By breaking the association between specific activities and food, it’s possible to rewire these habits and reduce cravings over time.
Environmental and Social Influences
Cravings are not only influenced by what’s happening inside our bodies and minds but also by our surroundings and social settings. Factors like the food environment, advertising, and even social gatherings can significantly impact what and how much we crave.
“Food environment” refers to the physical, social, and economic factors that shape our access to and selection of food, including the availability (or not) of healthy grocery stores and restaurants in our neighborhoods. Additionally, the prevalence of food delivery apps and pre-packaged meals means we’re constantly surrounded by tempting options that are quick and easy but not always nutritious.
Social influences such as family traditions, cultural norms, and peer behaviors can also impact what we crave and consume. Whether it’s a family dinner, a night out with friends, or a celebration, social situations can create additional pressure to indulge in foods we might otherwise avoid. Seeing others eat certain dishes, or simply being in a festive environment, can trigger cravings that have little to do with actual hunger.
Managing Cravings Mindfully
Understanding the triggers behind cravings is the first step toward managing them in a healthier, more intentional way. Mindful eating techniques can help us make more conscious food choices and break the cycle of impulsive eating.
Awareness of Triggers
One of the most effective ways to manage cravings is to become aware of what triggers them. By identifying whether cravings stem from stress, boredom, emotional needs, or environmental cues, you can start to address the root cause rather than automatically reaching for food. Practicing mindfulness allows you to pause and ask: Am I truly hungry, or is something else going on?
By bringing awareness to these moments, you can create space to make a more thoughtful choice about whether to indulge or find another way to meet your needs.
Mindful Eating Techniques
Mindful eating is about slowing down and being fully present while eating. This means paying attention to the flavors, textures, and sensations of each bite. By doing so, you’re more likely to feel satisfied with less food and better able to distinguish between actual hunger and cravings.
A few mindful eating tips include:
- Eat without distractions: Turn off screens and focus solely on your meal.
- Chew slowly: This helps you fully savor the food and gives your brain time to register satiety.
- Engage your senses: Notice the smell, taste, and texture of your food. This practice enhances the eating experience and can help reduce mindless snacking.
Emotional Regulation
Cravings are often a response to emotional states. Developing healthier coping mechanisms for stress, anxiety, or boredom can reduce the need to turn to food. Practices such as breathing exercises, meditation, or journaling can help calm your mind and provide a non-food outlet for dealing with emotions.
Learning to recognize the emotional cues behind cravings helps you manage them more effectively. When you’re mindful of these cues, you can choose to engage in self-care activities that nourish your well-being without reaching for comfort foods.
Balanced Eating
Another key strategy for managing cravings is maintaining a well-balanced diet. When your body is properly nourished, you’re less likely to experience extreme cravings driven by nutrient deficiencies or blood sugar imbalances. Ensuring you consume a diet rich in fiber, protein, and healthy fats helps stabilize your energy levels and reduces the frequency of cravings.

Hydration also plays a role. Thirst is sometimes confused with hunger, so staying hydrated throughout the day can prevent unnecessary snacking.
Conclusion
Cravings are a complex interplay of physical, mental, and environmental factors. Through following the Nature’s pHarmacy principles of mindful eating, emotional awareness, and maintaining a balanced diet, it’s possible to avoid the types of foods that lead to cravings, as well as manage any remaining cravings in a way that supports both physical health and emotional well-being. Learning to navigate cravings mindfully allows us to enjoy food with greater intention, making choices that serve our health rather than simply giving in to fleeting desires.
