When it comes to proteins, however, it is also important to focus on their quality which depends on the content of the amino acids defined as “essential” : our body needs them, but is unable to produce them on its own and must introduce them with food. There are 8 essential amino acids and in red meat proteins they are all present in high quantities so that our body can make the best use of them; for this reason it is said that red meat proteins have “a high biological value” and that they are “noble proteins”. On the contrary, vegetable proteins, such as legumes for example, are certainly important protein sources, but their proteins are deficient in two essential amino acids, methionine and cysteine, and therefore incomplete. Cereals, on the other hand, lack another essential amino acid, lysine, and despite combining the two foods (the typical example is pasta and beans) you get a meal that has all the essential amino acids, the biological value of red meat in any case it remains superior buy wagyu steak online.
Still legumes, and in particular soy, are widely used today to produce foods of vegetable origin proposed as protein substitutes for meat. In this case, while approaching (but not reaching) the levels of completeness and balance of red meat proteins, it should be clarified that these products are often the result of very sophisticated industrial techniques which use a quantity of different ingredients and additives which qualify as “ultraprocessed” foods, of which frequent consumption is not recommended.
Good sustainable farming practices: Origin Green project
The measure of the sustainability of a food does not concern the product itself, but the way in which it is obtained.
In the case of meat, the breeding of grazing cattle fed on grass as their nature would have it allows to obtain a better quality product with a lower environmental impact.
However, sustainability does not only concern the feeding of the animals, but also the maintenance of the spaces dedicated to breeding , starting from the consumption of water: in the case of pastures, such as those in Ireland, for example, rainwater is used to maintain the green and grassy meadows.
