Terms to understand about meat

Trans fat

A type of unsaturated fat primarily formed through industrial processes, such as the hydrogenation of vegetable oils, which alters its chemical structure. It is found in ultra-processed foods such as cookies, margarine, and snack foods. Frequent consumption is associated with increased LDL cholesterol (considered harmful) and reduced HDL cholesterol (protective), and is linked to a higher risk of cardiovascular disease.

Unsaturated fat

A type of fat found mainly in plant-based foods and fish. It is composed of unsaturated fatty acids and is divided into two subtypes: monounsaturated and polyunsaturated. These compounds are associated with various metabolic functions, including cardiovascular health, brain function, and the regulation of inflammatory processes.

Saturated fat

A type of fat found in animal-based foods (such as meat, cheese, milk, among others ) and some plant sources. It is composed of saturated fatty acids, which have a more stable chemical structure and play roles in energy storage and structural functions in the body.

Ultra-processed foods

Industrial products with formulations that include multiple ingredients and additives, such as colorings, flavorings, and preservatives, with little or no presence of the food in its original form.
