Which term refers to nutrients consumed by humans from food sources?

The term that refers to nutrients consumed by humans from food sources is "food." In the context of human consumption, "food" encompasses all the edible substances that provide nutrition, including carbohydrates, proteins, fats, vitamins, and minerals.

While "diet" describes the overall pattern of food and drink consumed by an individual or group, it does not specifically denote the nutrients themselves. "Feed" refers more often to animal nutrition and the provisions given to livestock rather than human consumption. "Nutrients" denotes the specific components found within food that are necessary for growth, metabolism, and other bodily functions. However, "food" is the broad category that contains these nutrients, making it the most accurate choice in the context of human consumption.
