One example of a fat with low nutritional value is a) avocados b) walnuts c) cheese d) salmon

The correct answer is C. Cheese

Explanation:

In nutrition, fats are an important element of diet; these are composed mainly of hydrogen and carbon and are a source of energy. Despite this, not all fat is the same and in the last decades, scientists have determined some have high nutritional value and are recommended while others have low nutritional value and lead to health issues.

In this way, foods such as avocados, walnuts, and salmon contain high levels of monounsaturated fats that are beneficial for health, also these foods have high nutritional value due to the minerals or vitamins in them. In the case of cheese, this contains high levels of fat but this is not as healthy as other foods and therefore is considered to have a low nutritional value; also, its consumption should be limited especially in case you follow a low-fat diet.
