Why is the focus on whole foods emphasized in FDN?

The emphasis on whole foods in Functional Diagnostic Nutrition is primarily due to their ability to reduce exposure to harmful processed ingredients. Whole foods, which include fruits, vegetables, whole grains, nuts, seeds, and lean proteins, are minimally processed and do not contain the additives, preservatives, and unhealthy fats often found in processed foods. These harmful ingredients can contribute to various health issues, including inflammation, digestive problems, and chronic diseases. By focusing on whole foods, individuals can support their overall health and well-being while providing their bodies with the nutrients they need.

The other options do not align with the core reasons for prioritizing whole foods in FDN. While whole foods might be more affordable or easier to prepare in some cases, this does not universally apply to all food choices. Additionally, whole foods are generally higher in fiber compared to processed foods, contrary to the statement suggesting they contain less fiber. Therefore, the significant focus is on reducing exposure to processed ingredients, making it clear why statement B is the most appropriate choice.
