In the complex world of nutrition and health, it’s not just the nutrients themselves that play a role, but also how these substances are processed by our bodies. A lesser known, but important part of this are exorphins. These are opioid-like substances that are released during the digestion of certain foods. These substances can directly affect our brain chemistry, with potentially detrimental effects on our health. In this blog, we’ll take a closer look at what exorphins are, how they work, the role of the DPP-IV enzyme in controlling their effects, and which foods contain them.
What are exorphins?
Exorphins are peptides that are produced during the digestion of certain proteins in food. They are structurally similar to endorphins, the natural opioids our bodies produce that play a role in pain relief and feelings of well-being. By binding to the same receptors as endorphins, exorphins can have similar effects on the brain, creating a sense of reward or pleasure. Like endorphins, exorphins briefly activate the dopaminergic reward system in the brain. As a result, we are “rewarded” for eating foods that provide exorphins. When overexposed, this can lead to addictive behavior, emotional attachment to food, and other health problems.
How do exorphins work on the brain?
Exorphins affect the brain by binding to opioid receptors. These receptors are responsible for regulating pain, mood, and feelings of pleasure. When exorphins bind to these receptors, they stimulate the release of neurotransmitters such as dopamine and serotonin, which contribute to feelings of reward, happiness, and relaxation. This may seem positive, but continued exposure can lead to addiction and disrupt the natural balance of neurotransmitters in the brain.
For example, the pleasure you feel after eating cheese or bread can be partly explained by the presence of exorphins. These substances make your brain think it is receiving a natural reward, which can result in cravings and dependence on specific foods. This explains why some people have difficulty resisting certain foods, even when they are aware of the negative consequences for their health.
The Role of the DPP-IV Enzyme
A key element in the way our body deals with exorphins is the enzyme DPP-IV (dipeptidyl peptidase IV). This enzyme plays a crucial role in breaking down exorphins, helping to reduce their effects. DPP-IV breaks down specific peptide bonds in the proteins released during digestion, making exorphins less active.
For example, when you eat gluten or casein, these proteins are broken down in the stomach and intestines into smaller fragments, including exorphins. The DPP-IV enzyme can further break down these exorphins, making them less potent and reducing their effects on the brain. This prevents exorphins from binding to opioid receptors for a long time and causing addictive feelings or behaviors.
Why is DPP-IV important?
A well-functioning DPP-IV enzyme can help minimize the impact of exorphins. People with a deficiency or reduced activity of this enzyme may be more sensitive to the effects of exorphins.This can lead to problems such as addiction to certain foods, digestive problems, and even psychological problems such as anxiety and depression.
In addition, decreased DPP-IV activity is often associated with conditions such as celiac disease and irritable bowel syndrome (IBS). This may explain why people with these conditions are extra sensitive to gluten and other foods containing exorphins. Supplementing with DPP-IV or making dietary changes can help support the activity of this enzyme and thus limit the negative effects of exorphins.
Which foods/products contain exorphins?
Exorphins are present in several commonly consumed foods:
Dairy products: Casomorphins are exorphins released during the digestion of casein, a protein found in milk and cheese.
Gluten-containing grains: Gliadorphins, also called gluten exorphins, are produced during the digestion of gluten, which is found in grains such as wheat, rye, and barley. This type of exorphin may contribute to gluten sensitivity or celiac-like symptoms in some people.
Soy: During the digestion of soy proteins, peptides are formed that can bind to opioid receptors, which explains why some people have difficulty digesting soy products.
Spinach: Although less well known, spinach leaves also contain exorphins. Although their effect is less potent, they can still have an impact on brain chemistry.
Health Problems Associated with Exorphins
Although exorphins can provide a short-lived pleasurable feeling, excessive intake can lead to several problems. Here are some conditions that have been linked to increased exposure to exorphins:
Addiction and dependency: Due to their ability to activate opioid receptors in the brain, exorphins can have an addictive effect. This may explain why some people have strong cravings for foods such as cheese, bread or (milk) chocolate.
Digestive problems: Exorphins can disrupt digestion, especially in people with gluten or lactose sensitivity. The body may have trouble fully breaking down these proteins, which can lead to stomach upset, bloating, and other digestive problems.
Cognitive dysfunction: Some studies suggest that excessive exorphin intake may contribute to problems with concentration, memory, general brain function, ADHD-related symptoms, and experiencing brain fog. This is because exorphins can disrupt the balance of neurotransmitters.
Mental problems: Exorphins have also been linked to mental health conditions such as depression and anxiety. Because they affect levels of neurotransmitters such as serotonin and dopamine, unbalanced consumption can lead to fluctuations in mood and emotional well-being.
How can you limit exorphin intake?
Given the potential negative effects of exorphins, it is wise to limit your intake, especially if you find yourself frequently craving foods rich in these substances.Here are some tips:
Avoid excessive consumption of dairy and gluten: If you find yourself frequently craving cheese, bread, or other dairy and grain products, try gradually reducing these foods or replacing them with alternatives such as plant-based milk or gluten-free products.
Eat more unprocessed foods: A diet rich in whole, natural foods can help limit exorphin intake. Choose vegetables, fruits, nuts, seeds, and organic meats and fish.
Support intestinal health and DPP-IV activity: Because exorphins are absorbed through the gut, improving gut health can help minimize their effects. This can be done by taking probiotics, eating fiber-rich foods, and avoiding highly processed foods. Supplements containing DPP-IV can also be helpful for people who have difficulty digesting gluten and casein.
Conclusion
Exorphins are a fascinating yet complex part of how food affects our bodies and minds. While they can provide short-term pleasure, prolonged and excessive exposure can lead to addiction and other health problems. The DPP-IV enzyme plays a key role in mitigating these effects and can help maintain healthy brain chemistry. By consciously choosing healthy, whole foods and supporting DPP-IV activity, you can contribute to greater well-being and more balanced health.
