The national pork belly comes from the Community of Madrid and is recognized for its richness in nutrients. This type of meat, while varying in fat content depending on the portion, offers multiple health benefits. Lean meat is particularly effective in diets aimed at weight loss as it provides a good amount of protein that supports muscle growth and satiety. Furthermore, pork is a source of thiamine, crucial for carbohydrate absorption, and zinc, vital for maintaining bones and muscle systems. Consuming lean pork parts may improve dietary quality and prevent diseases, according to the Spanish Nutrition Foundation.
