Abstract
Meat is considered to be a good source of protein with high biological value as well as of micronutrients such as minerals (iron, zinc, selenium, …) and vitamins (B6, B12, A, D, …) with a high degree of bioavailability. These micronutrients are either not present in plant-derived food or have poor bioavailability. Consequently, consuming moderate amounts of lean meat as part of a balanced diet makes a valuable contribution to the intake of essential nutrients [1]. However, some constituents of meat, especially in red meat and meat products, have been proposed to be responsible for the development of cardiovascular disease and colon cancer. These elements include the fat content and the fatty acid composition. Meat and meat products are generally classified as “high-fat products”, although the various products available differ markedly in terms of their total fat content. Meat is generally considered to have a fat content in the range 1–20 %, depending on the retail cut and the amount of fat trimmed. Both the fat content and fatty acid composition of meat are influenced by factors such as species, breed, sex, age/weight and diet [2]. Figure 5.1 shows the fat content and fatty acid composition of some meats and meat products obtained from different species. The fat content is usually higher in processed meat products (5–40 %), where large amounts of fatty tissue are used.
