There is no scientific evidence to suggest that certain spices are specifically beneficial or harmful for people with blood type B. The concept of blood type diets is not supported by mainstream medical science.
While the idea of aligning food choices with blood type is intriguing, there's no robust scientific basis for it. Your dietary needs are influenced by various factors like your overall health, activity level, and individual preferences.
Instead of focusing on blood type-specific diets, it's always best to consult with a registered dietitian or healthcare professional for personalized dietary advice. They can help you create a balanced and healthy eating plan that meets your specific requirements.
