In December 2019 researchers from Spain published their review on the association between dietary habits and the risk of developing diabetes type 2. Results showed that animal protein intake increases the risk of diabetes type 2, independently of body mass index. An intake of both unprocessed meat and processed meat is strongly and consistently associated with an increased risk of developing diabetes type 2 whereas the consumption of plant foods appears to reduce the risk. Plant foods include whole grains, nuts, legumes, fruits, and vegetables. Among less healthy plant-based foods are fruit juices, sweetened beverages, refined grains, potatoes, sweets, and desserts. Carbohydrate-restricted diets that encourage consumption of animal products promote diabetes type 2. According to the American Dietetic Association, “appropriately planned vegetarian diets including vegan diets are healthful, nutritionally adequate, and may provide health benefits in the prevention and treatment of certain diseases”.
