Which of the following is a strategy that enhances nutrient absorption?

Combining foods to maximize nutrient availability is an effective strategy for enhancing nutrient absorption. Different foods contain a variety of nutrients that can complement each other, making it easier for the body to absorb vitamins and minerals. For instance, consuming foods rich in vitamin C, such as citrus fruits, alongside iron-rich foods like spinach can significantly enhance the absorption of non-heme iron. This is because vitamin C converts iron into a form that is more readily absorbed by the body.

Additionally, certain food combinations can promote the absorption of fat-soluble vitamins (A, D, E, and K) when foods containing healthy fats are included. For example, adding a source of fat, like olive oil, to vegetables can improve the absorption of these vitamins.

In contrast, eating only single food types can limit the range of nutrients available, while avoiding food combinations may hinder the body's ability to absorb certain nutrients efficiently. Similarly, consuming processed foods often leads to reduced nutritional quality, making it less likely that one is maximizing nutrient intake through effective combinations. Thus, strategically combining foods enhances nutrient availability and absorption, making it the most effective approach.
