What is Vegetarian Cheese?
Vegetarian cheese is a product made from milk, just like conventional cheese, but it uses a non-animal coagulant to separate the curds from the whey. The key difference lies in the rennet—the enzyme mix that causes the milk to curdle. While traditional rennet is sourced from the stomachs of young ruminant animals, vegetarian rennet is derived from alternative, cruelty-free sources.
The Role of Rennet
Rennet is a crucial component in cheesemaking. It contains enzymes, primarily chymosin, that cause the milk to coagulate. For a vegetarian-friendly cheese, the source of these enzymes is what matters most. The three main types of rennet are:
- Animal Rennet: The traditional method, extracted from the fourth stomach of young, unweaned calves, lambs, or kids.
- Microbial Rennet: Produced by fermenting certain fungi, molds, or bacteria, it is the most common type used in modern commercial cheese production. Fermentation-produced chymosin (FPC), a highly purified and consistent microbial rennet, dominates the market.
- Plant-Based Rennet: Extracted from plants such as artichoke thistle or fig leaves. This method is less common commercially and can sometimes impart a slightly bitter taste to aged cheeses.
Because the vast majority of vegetarian cheese on the market uses microbial rennet, its core nutritional profile is virtually identical to cheese made with animal rennet. Both are made from milk and therefore contain dairy-based fats, protein, calcium, and cholesterol.
Nutritional Comparison: Vegetarian vs. Regular vs. Vegan Cheese
Comparing the healthiness of cheese requires looking beyond just the rennet. The real differences emerge when you compare vegetarian dairy cheese to plant-based vegan cheese alternatives.
The Dairy Factor
Since vegetarian cheese is still a dairy product, it shares the nutritional benefits and drawbacks of conventional cheese. It is a good source of protein and calcium, but also contains saturated fat and cholesterol. A study by the Center for Science in the Public Interest noted that while dairy cheese can be high in saturated fat, some research suggests it might not be linked to the same heart disease risks as saturated fats from other sources.
The Vegan Distinction
Vegan cheese, in contrast, is fundamentally different. It is made from plant-based ingredients, such as nuts (cashews, almonds), soy, or coconut oil. This means it is free of cholesterol and often lower in saturated fat, though some coconut oil-based versions can be high in saturated fat. A major drawback of many vegan cheeses is their low protein and calcium content unless fortified. The use of additives and starches in highly processed vegan cheese can also be a concern.
Choosing the Healthiest Option
For vegetarians, the question isn't whether their cheese is healthier than regular cheese—it’s how to choose the healthiest cheese overall. The type of rennet is a moral consideration, not a nutritional one.
Tips for choosing a healthier cheese:
- Check the ingredients list: For highly processed products (both dairy and vegan), a shorter, simpler list is usually better. Look for products made from whole foods like nuts, if considering vegan options.
- Compare sodium levels: Many commercial cheeses, both vegetarian and vegan, can be high in sodium. Always check the nutrition label and choose varieties with lower sodium content.
- Consider fat and calories: If calorie or saturated fat intake is a concern, opt for reduced-fat or lower-calorie varieties, such as part-skim mozzarella or goat cheese.
- Look for fortified vegan cheeses: If opting for a plant-based alternative, ensure it is fortified with vital nutrients like calcium and vitamin B12.
- Prioritize moderation: As with any food, moderation is key. Portion sizes of around 30 grams are recommended to enjoy the flavor without overindulging in fat and sodium.
Comparison Table
| Feature | Regular Dairy Cheese | Vegetarian Dairy Cheese | Vegan Cheese |
|---|---|---|---|
| Rennet Type | Animal-derived (traditional) | Microbial or Plant-based | None (plant-based) |
| Primary Ingredients | Milk, salt, cultures | Milk, salt, cultures | Nuts, seeds, soy, coconut oil, starches |
| Protein | High | High | Varies (often low, unless nut/soy-based) |
| Calcium | High | High | Varies (often low, unless fortified) |
| Saturated Fat | High (dairy fats) | High (dairy fats) | Varies (some high in coconut oil, some low) |
| Cholesterol | Contains cholesterol | Contains cholesterol | No cholesterol |
| Sodium | Can be high | Can be high | Can be high |
| Processing Level | Varies (from artisanal to processed) | Varies (from artisanal to processed) | Varies (some artisanal, many ultra-processed) |
| Long-Term Aging | Often preferred for flavor development | Some microbial/plant rennets can impart bitterness in aged cheeses | Not applicable; aged vegan cheeses are an artisan product. |
Conclusion: The Bottom Line on Vegetarian Cheese
The healthiness of vegetarian cheese is not determined by its rennet, but rather by its overall nutritional composition, which mirrors that of regular dairy cheese. For the health-conscious individual, the key takeaways are to prioritize overall dietary balance, read labels to manage sodium and saturated fat intake, and distinguish between dairy-based vegetarian cheese and plant-based vegan alternatives.
While vegetarian cheese can be a good source of protein and calcium, it is still a dairy product that should be consumed in moderation, especially considering its saturated fat and cholesterol content. For those seeking a truly different health profile, vegan cheese offers a cholesterol-free option, but requires careful selection to ensure it isn't overly processed or lacking in essential nutrients like protein and calcium. Ultimately, the healthiest approach is to enjoy cheese as part of a balanced diet, regardless of the rennet type used.
