Final answer:
A healthy diet should include a variety of fruits and vegetables, not be high in saturated fats, contain adequate fiber, and not exclude protein-rich foods.
Therefore , option 1) is correct.
Step-by-step explanation:
When considering which dietary patterns promote optimal nutritional status, several factors are important. A healthy diet should include a variety of fruits and vegetables, as these are high in vitamins, minerals, and fiber. Foods that are high in saturated fats should be limited, as overconsumption of these is linked to negative health outcomes. Instead, one's diet should be high in foods that provide adequate fiber, which are beneficial for digestive health and can help regulate blood sugar levels. Protein is also essential for repairing tissue and maintaining muscle mass, so a healthy diet should not exclude protein-rich foods. Overall, an optimal dietary pattern is one that is balanced and includes a wide range of nutrients from whole foods, controls calories to match energy expenditure, and emphasizes moderation and variety.
Specifically responding to the provided options, the true recommendation for promoting optimal nutritional status is that dietary patterns should include a variety of fruits and vegetables. They should not be high in saturated fats, nor should they be low in fiber or exclude protein-rich foods.
