Nutrient-Dense Foods Reference Guide

This guide provides a comprehensive list of nutrient-dense foods organized by food group, with information on key nutrients, practical tips for incorporation, and storage guidance.

What Makes a Food “Nutrient-Dense”?

Nutrient-dense foods provide substantial amounts of vitamins, minerals, beneficial plant compounds, and other nutrients relative to their calorie content. These foods give you more nutritional “bang for your buck,” helping you meet your nutrient needs without excessive calories.

Incorporating Nutrient-Dense Foods

Balanced Meal Formula

Create meals that include: - At least 1-2 servings of vegetables or fruits - A portion of protein - Some whole grains or starchy vegetables (portion based on activity level) - A small amount of healthy fat

Nutrient Density Boosting Strategies

• Add extra vegetables to soups, stews, and sauces
• Include a side salad with meals
• Snack on fruits, vegetables, and nuts rather than processed snacks
• Use herbs and spices liberally for flavor
• Choose whole food forms over processed versions when possible

Practical Shopping Tips

• Shop the perimeter of the store first (where most whole foods are located)
• Buy fruits and vegetables in season for best flavor and value
• Consider frozen fruits and vegetables for convenience and longevity
• Buy in bulk when appropriate for cost savings
• Plan meals around nutrient-dense foods rather than building meals around less nutritious options

Remember that nutrient density exists on a spectrum—focus on including more nutrient-dense options rather than creating rigid categories of “allowed” and “forbidden” foods. The goal is a pattern of eating that provides abundant nutrition while still being enjoyable and sustainable.
