Dietary Variety and Whole Foods

Whole Foods

Whole foods are minimally processed foods retaining most original components:

• Vegetables, fruits, legumes in fresh or dried forms
• Whole grains (oats, brown rice, quinoa, etc.)
• Nuts, seeds, and their butters
• Unprocessed animal products (meat, fish, dairy)
• Eggs
• Herbs and spices

Characteristics of Whole Foods

• Retain dietary fiber
• Contain naturally occurring micronutrients and phytonutrients
• Provide varied texture and flavor experiences
• Require active preparation
• Support satiety through fiber and complexity

Processed Foods

Processing exists on a continuum. Some processing (freezing, canning, pasteurization) maintains nutritional value and extends availability. Other processing (adding sugars, sodium, or artificial components) changes nutritional profile substantially.

Dietary Diversity

Different foods provide different nutrients and beneficial compounds. Consuming a variety of foods—different vegetables, fruits, whole grains, proteins, and healthy fats—helps ensure comprehensive nutrient intake and provides varied phytochemicals and other beneficial compounds.

Individual Circumstances

The optimal balance of whole and processed foods varies for individuals based on time availability, cooking ability, budget, taste preferences, digestive tolerance, cultural background, and life circumstances. There is variability in what constitutes appropriate dietary choices across different situations.
