Final answer:
The statement is true; lean, whole food options are recommended for dietary protein because they typically contain complete proteins, essential nutrients, and less saturated fat, contributing to a balanced and healthy diet.
Step-by-step explanation:
The statement, 'Most dietary protein should come from lean, whole food options,' is TRUE. Dietary proteins are essential nutrients that contain amino acids, which are the building blocks of body structures such as muscles and skin, and serve functions such as enzymes, hormones, and antibodies. While it is possible to get protein from a variety of sources, the healthiest options tend to be lean meats like chicken and fish, as well as plant-based sources such as beans and legumes. Lean proteins are preferred as they contain less saturated fat. Consuming excessive amounts of fat, especially saturated fat, can lead to health issues such as heart disease.
Furthermore, proteins that provide all nine essential amino acids are known as complete proteins. Complete proteins are typically found in animal products and are important for a balanced diet. However, it is also possible to combine different plant-based foods to consume all essential amino acids even if they individually contain only incomplete proteins. Whole foods are recommended over highly processed options and supplements because they not only contain proteins but also other valuable nutrients and dietary fiber.
