1. Type A

According to D’Adamo, individuals with blood group A are distinguished by low levels of hydrochloric acid and high levels of disaccharidases (carbohydrate digestive enzymes) in their intestines. Consequently, it is challenging for individuals with this blood group to digest meat and animal products, yet they manage exceptionally well with vegetables and starchy products. It is recommended that they adhere to a meat-free diet based on plant-based, natural, unprocessed foods. They should also avoid and limit the consumption of coffee, alcohol, and sugar. This is associated with higher cortisol levels and a more pronounced response to stressors than in other blood groups. Practicing relaxation exercises, such as breathing exercises like Tai Chi or Yoga, can assist in stress reduction. Furthermore, these individuals should remember to maintain meal regularity and consume them in a tranquil atmosphere, as well as thoroughly chew their food to facilitate digestion.

2. Blood Type B

This blood group originated from our predecessors who resided in the Himalayas of modern-day India and Pakistan. Consequently, they had to adapt to the existing climate, which differed from the conditions on the savannah. As a result, individuals with the B antigen are easily adaptable to change. Products that enhance the adiposity of these individuals and pose a risk of hypoglycemia (low blood glucose levels) following consumption include maize, wheat, buckwheat, chickpeas, tomatoes, nuts, sesame seeds. Poultry is also not recommended, as it contains lectins causing agglutination. Recommended consumption includes game, rabbit, veal, low-fat dairy, eggs, green vegetables. Exercises engaging both the muscles and the mind, such as tennis, mountain climbing, golf, are advised. Visualization is also recommended as a technique facilitating the achievement of set goals. Maintaining sleep hygiene is also advised - one should sleep for no less than 8 hours daily and retire before 11:00 PM. People with Type B blood are purportedly in need of human interaction, making involvement in local communities advisable.

3. Type 0

According to the originator of the diet, individuals with blood type 0 often suffer from gastric ailments such as stomach diseases due to the increased production of hydrochloric acid in the stomach. Better adaptation to digesting meat products, cholesterol, and fat metabolism is also characteristic of this group. Excessive consumption of carbohydrates, especially simple sugars, leads to weight gain in them. Products not recommended for consumption include wheat, soybean oil, peanuts, and beans. The diet's creator recommends intense physical activity for individuals with blood type 0, which should be carried out for at least 30 minutes, at least four times a week. Regular exercise has a positive impact on mental health and is also advisable in situations of strong cravings for substances such as alcohol or cigarettes.

4. Type AB

Therefore, it is recommended that these individuals not consume a meal of carbohydrate and protein sources. They should avoid smoked and cured meats. Alcohol and caffeine are particularly unfavorable for these individuals. They may be susceptible to stomach cancer. They should also avoid bananas, corn, and poultry. Therefore, in their schedule, these individuals should consider both intense and relaxing exercises. Visualization technique is also recommended for them.
