Cheese Varieties And Their Dopamine Content: A Comprehensive Guide

Cheese is a beloved food for many, but why is it so addictive? Cheese contains a protein called casein, which, when digested, releases casomorphins, plant compounds that trigger dopamine production in the brain. This causes feelings of pleasure and reward, making you want to eat more cheese. While cheese is not an addictive substance like drugs or alcohol, it does have an addictive allure due to its sensory attributes, cultural significance, and the interaction of compounds like casomorphins with our brain's reward system. So, which type of cheese has the most dopamine? Let's find out!

High-fat content in cheese makes it easy to crave

Cheese is a food that is notoriously hard to give up. But why? Well, it's all to do with its chemical makeup.

Cheese contains a protein called casein, which is found in all dairy products. When casein is digested, it breaks down into casomorphins. These casomorphins are plant compounds that trigger dopamine production in your brain. Dopamine is a neurotransmitter related to feelings of pleasure and reward. The more casomorphins your brain is exposed to, the more pleasure you experience, and the more you will crave foods like cheese.

But it's not just the casomorphins that make cheese so moreish. Cheese is also high in fat, which can make it very satisfying and pleasurable to eat. Fats stimulate the release of feel-good neurotransmitters like dopamine in the brain, which can contribute to the sensation of craving more.

In fact, one study found that processed and high-fat foods, including cheese, promoted more addictive eating behaviours than less processed, lower-fat foods. These foods may directly affect pleasure receptors in the brain. This may be due to an evolutionary component, as high-fat foods were likely a survival mechanism for prehistoric humans.

So, while cheese may not be dangerous or unhealthy, its high-fat content, in combination with casomorphins, makes it a very craveable food.

Cheese contains casein, which releases casomorphins

Cheese contains casein, a protein that releases casomorphins when digested. Casein comprises the majority of protein in dairy milk, and the concentration of casein in cheese is even higher, as it takes around 10 pounds (4.5 kg) of milk to make 1 pound (0.5 kg) of cheese.

When casein is digested, it breaks down into smaller compounds called casomorphins. Casomorphins are peptides that can have opioid-like properties and influence our bodies in various ways. They can cross the blood-brain barrier and attach to opioid receptors in the brain, specifically dopamine receptors. This attachment triggers the release of dopamine, a neurotransmitter associated with feelings of pleasure and reward. Essentially, the more casomorphins your brain is exposed to, the more pleasure you experience, which may lead to cravings for cheese and other dairy products.

Casomorphins are thought to have an important evolutionary purpose in mammals by promoting the strong bond between mother and baby. The opiate-like compounds in milk reward the baby for nursing, ensuring they continue to drink their mother's nutrient-rich milk. This helps explain the intense look of satisfaction on a nursing baby's face before they fall into a peaceful sleep.

While cheese contains compounds that trigger dopamine production and may be mildly addictive, it is important to clarify that cheese is not a drug. The term "addictive" in relation to cheese refers to the pleasurable responses and cravings it can elicit, which are distinct from the intense, harmful cravings and dependency associated with drugs and alcohol. Cheese's allure is a result of a complex interplay of factors, including its fat content, umami flavour, texture, salt content, cultural significance, and the presence of casomorphins.

Casomorphins trigger dopamine production in the brain

Cheese contains a protein called casein, which is present in all dairy products. When casein is digested, it breaks down into smaller compounds called casomorphins. These casomorphins can cross the blood-brain barrier and attach to opioid receptors in the brain, specifically the dopamine receptors. This attachment triggers the release of dopamine, a neurotransmitter associated with feelings of pleasure and reward.

Casomorphins are essentially peptides with opioid-like properties, resembling opioid molecules in structure. They get their name from the combination of the words "casein" and "morphine". While casomorphins have a similar effect on the brain as opioids, the effects are much milder and do not lead to intense cravings or dependency as seen with drugs.

The release of dopamine caused by casomorphins leads to an elevation in mood and a sense of satisfaction, which may explain why people crave cheese and similar foods. This mechanism may have an evolutionary purpose, promoting the bond between mother and baby, ensuring that infants continue to nurse and receive their mother's nutrient-rich milk.

The concentration of casein in cheese is higher than in milk due to the amount of milk required to make cheese. This results in a higher concentration of casomorphins in cheese, making it a potent trigger for dopamine production.

In addition to the effects of casomorphins, other factors contribute to the addictive nature of cheese. Cheese is relatively high in fat, which stimulates the release of feel-good neurotransmitters like dopamine. It is also rich in umami, a savoury taste that is highly rewarding to the taste buds. The texture, salt content, and cultural and social associations of cheese further enhance its appeal and contribute to its potential habit-forming nature.

Cheese is linked to cultural and social factors

Cheese is also linked to cultural and social factors through the rituals and traditions that surround it. For instance, the process of making cheese can be a ritual in and of itself. In the French Basque Pyrenean village of Sainte-Engrâce, the local shepherds treat the cheese produced in their mountain huts with the same care and attention that they would give to their children. In some regions of Italy, cheese plays a symbolic role as a social currency in a competition called tiro al cacio, where contestants toss or roll real cheeses at a mark or goal. The contestant whose cheese lands closest to the mark wins all the other contestants' cheeses.

Finally, cheese is linked to cultural and social factors through the memories and emotions that surround it. For example, young Cypriots' consumption of hellim/halloumi is influenced by memories of their grandparents making the cheese, and the taste of mature hellim/halloumi reminds them of their childhood.

Cheese is rich in umami, one of the five basic tastes

The main compound responsible for umami is glutamate, a type of amino acid. When glutamate interacts with taste receptors on the tongue, it creates the signature savoury flavour. In cheese, umami develops as proteins break down into smaller molecules during the ageing process. This process, known as proteolysis, is driven by milk enzymes, starter cultures, and moulds or bacteria. The longer the bacteria are active, the more intense the savoury flavour becomes.

Some examples of glutamate-rich cheeses include:

• Parmigiano Reggiano (1200 - 2200 mg/100g)
• Comté (539 - 1570 mg/100g)
• Cabrales (~760 mg/100g)
• Aged Cheddar (173 - 718 mg/100g)
• Roquefort (~471 mg/100g)
• Emmentaler (~307 mg/100g)
• Aged Gouda (~295 mg/100g)

The concentration of free glutamate in cheese typically increases during the ageing process, with older cheeses having a stronger umami flavour. However, over-ageing can lead to imbalances where other flavour compounds may dominate.

While cheese is indeed rich in umami, it is also mildly addictive due to its protein casein, which can trigger cravings for similar foods. When you digest casein, your body breaks it down into smaller compounds called casomorphins. Casomorphins can cross the blood-brain barrier and attach to dopamine receptors in your brain, causing the release of dopamine, a neurotransmitter related to feelings of pleasure and reward.
