Why is macaroni and cheese a complete protein?

Answer 1

Oh, dude, mac and cheese is a complete protein because when you combine macaroni and cheese, you get all the essential amino acids your body needs to function properly. It's like a delicious tag team of nutrients that your body can use to build and repair itself. So yeah, mac and cheese isn't just comfort food, it's also low-key keeping you fueled and ready to tackle the day.

Answer 2

Both together form a complete protein. There is a myth that macaroni itself alone is incomplete, and that cheese and other products usually made from animal products are complete. So how did this myth come about?

In 1914, Thomas B. Osborne and Lafayette B. Mendel conducted studies on rats, which suggested that they grew best when fed a combination of plant foods whose amino acid patterns resembled that of animal protein. That makes sense, as all baby mammals, rats and humans included, grow best when fed the perfect food for baby mammals: their mother's milk. The term "complete protein" was coined to describe a protein in which all eight or nine essential amino acids are present in the same proportion that they occur in animals. "Incomplete protein" described the varying amino acid patterns in plants. It's a misleading term, because it suggest that humans (and other animals, one would assume) can't get enough essential amino acids to make protein from plants.

Fortunately, the theory that plant proteins are somehow "incomplete" and therefore inadequate has been disproven. All unrefined foods have varying amounts of protein with varying amino acid profiles, including leafy green vegetables, tubers, grains, legumes, and nuts. All the essential and nonessential amino acids are present in any single one of these foods in amounts that meet or exceed your needs, even if you are an endurance athlete or body builder.
