Understanding the Blood Type O Diet and Dairy
For followers of the Blood Type Diet, specific dietary recommendations are determined by a person's ABO blood type. This diet, developed by naturopathic doctor Peter D'Adamo, suggests that individuals with Blood Type O should thrive on a high-protein, meat-heavy diet, similar to their 'hunter-gatherer' ancestors. Conversely, this dietary approach recommends limiting or avoiding certain food groups, including most grains, legumes, and dairy products, to support optimal health and weight management.
The rationale behind avoiding dairy for Type O individuals lies in the theory that their digestive systems may not be well-adapted to process these foods effectively. Proponents of the diet suggest that the lectins found in many dairy products can cause agglutination, or a 'clumping' of blood cells, which can trigger inflammatory responses and lead to digestive issues. While the scientific community has not broadly accepted the blood type diet, many people report feeling better after following its guidelines, often attributing improvements to the increased focus on lean protein and fresh produce.
Neutral and Acceptable Cheeses for Blood Type O
While the diet advises severe restriction of dairy, not all cheeses are strictly forbidden for Blood Type O individuals. Some varieties are listed as 'neutral,' meaning they can be consumed occasionally and in moderation without causing a significant negative reaction. These neutral options provide a way to include cheese in a Type O diet for variety and flavor.
Tolerated Cheeses:
- Feta Cheese: A classic example of an acceptable cheese, feta is mentioned as a good choice due to its potential compatibility with the Type O digestive system.
- Goat Cheese: Similar to feta, goat cheese is often cited as a suitable dairy option for Type O individuals, especially when sourced organically.
- Mozzarella: This soft cheese is typically classified as neutral and can be consumed occasionally. It’s a versatile option for adding to salads or other recipes in moderation.
- Farmer Cheese: Sometimes referred to as a neutral option, farmer cheese is a simple, unripened fresh cheese that can be a mild inclusion.
- Soy Cheese: For those who wish to avoid animal dairy entirely, soy cheese is listed as a neutral alternative that aligns with the Type O diet recommendations.
Cheeses to Avoid on the Blood Type O Diet
The list of cheeses to avoid is significantly longer, as most conventional, store-bought dairy cheeses are not recommended for Blood Type O individuals. These are thought to contain lectins or other compounds that are incompatible with the Type O digestive tract. Limiting these is a core component of the diet's strategy for weight management and anti-inflammatory benefits.
Cheeses to Strictly Avoid:
- Common Aged Cheeses: This includes varieties like Cheddar, Swiss, Jarlsburg, and Gouda, all of which are on the avoid list.
- Soft Ripened Cheeses: Brie and Camembert are specifically mentioned as cheeses to stay away from.
- Blue and Mold-Ripened Cheeses: Blue cheese is another variety recommended for avoidance.
- Processed Cheeses: American cheese and other processed, pre-packaged cheese products are generally considered detrimental on this diet.
- Cottage and Ricotta: While some sources may offer conflicting advice, many core resources for the blood type diet list these as cheeses to avoid or consume with extreme caution.
Comparing Cheese Options for Blood Type O
This table provides a simple overview of cheese compatibility based on the Blood Type Diet's principles. Remember that personal tolerance can vary, and this table serves as a general guide.
| Cheese Category | Neutral/Tolerated Cheeses | Cheeses to Avoid |
|---|---|---|
| Soft & Fresh | Feta, Goat cheese, Mozzarella, Farmer cheese | Ricotta, Cottage cheese |
| Aged & Hard | None listed as beneficial/neutral. | Cheddar, Parmesan, Swiss, Provolone |
| Specialty | Soy cheese | Blue cheese, Brie, Camembert |
| Processed | None. | American cheese, String cheese |
The Role of Individual Tolerance and Scientific Consensus
While the Blood Type Diet offers a structured approach, it is crucial to recognize that it lacks widespread scientific backing. Many mainstream nutrition experts point out that there is little evidence to support the idea that blood type determines optimal dietary choices. A person's individual reaction to specific foods, including dairy, can be a more reliable indicator of what is best for their body.
For some with Blood Type O, the recommendation to limit dairy may simply align with an underlying lactose intolerance or other food sensitivity that they were already experiencing. For others, moderate consumption of dairy may not cause any issues. It's always best to listen to your body and observe how you feel after eating different types of cheese.
Alternative Approaches to Dairy
For those who find that even the neutral cheeses cause discomfort, or who wish to eliminate dairy completely, several delicious alternatives exist:
- Soy Cheese: As a pre-approved neutral option, soy cheese is a great starting point.
- Nut-Based Cheeses: Many commercial nut-based cheeses, made from ingredients like cashews or almonds, can mimic the texture and flavor of traditional dairy cheese.
- Nutritional Yeast: This provides a savory, cheesy flavor to dishes without using any dairy products.
- Dairy-Free Parmesan: Homemade or store-bought dairy-free versions can be made from a blend of nuts, seeds, and spices.
Ultimately, the Blood Type Diet provides a framework for managing food intake based on a specific theory. While not scientifically proven, its focus on whole foods and limitation of processed items often leads to healthier eating habits for many individuals. For Blood Type O followers, understanding the distinction between neutral and avoided cheeses is a key step in navigating the diet successfully.

Conclusion
In summary, while the Blood Type Diet advises Blood Type O individuals to be cautious with dairy, not all cheese is off-limits. Neutral cheeses such as feta, goat cheese, and mozzarella are considered acceptable in moderation. Meanwhile, most hard and processed cheeses are on the avoidance list. The effectiveness of this diet varies, and individual tolerance to dairy should be the primary guide. Ultimately, listening to your body, consulting with a healthcare professional, and exploring suitable alternatives can help Blood Type O individuals find a sustainable way to include or replace cheese in their diet.
