Defining Wholefood: The Minimal Processing Rule
At its core, the simple answer to what counts as wholefood is any food that is unprocessed, unrefined, or as close to its natural state as possible. This includes fresh fruits and vegetables, whole grains, legumes, and unprocessed animal products. While the ideal wholefood has no ingredient list at all—like an apple or a carrot—many modern wholefoods undergo some minimal processing for safety, storage, or palatability. Washing, chopping, freezing, and pasteurizing are all examples of minimal processing that do not significantly alter the food's nutritional profile.
The Spectrum of Processing: Minimally vs. Ultra-Processed
It's important to understand that processing exists on a spectrum, and not all processed food is bad. The key is to differentiate between minimally processed foods and heavily or ultra-processed foods.
- Minimally Processed: These foods have been altered only slightly from their natural state. This includes items like frozen fruits and vegetables without added sauces, pre-washed spinach, dried lentils, or whole wheat flour. The intent is to preserve the food's integrity or make it more convenient without adding unhealthy ingredients.
- Processed: This category includes foods with added ingredients like salt, sugar, or fat for preservation or to improve flavor. Examples include canned beans (check for low sodium), cheeses, and plain yogurt. These can still be part of a healthy diet in moderation.
- Ultra-Processed: These are the foods to limit. They are made mostly from cheap, industrial ingredients and contain a long list of additives, artificial flavors, preservatives, and high levels of added sugar, fat, and sodium. Examples include sugary cereals, most packaged snacks, frozen dinners, and soda. These foods are often low in nutrients and high in empty calories.
Examples of Wholefoods in Every Food Group
Building a diet around wholefoods involves choosing items from a wide range of food groups. Here is a list of common wholefood examples:
- Fruits: Apples, bananas, berries, oranges, and melons. Eating whole fruit is more beneficial than drinking juice, as the fiber helps slow sugar absorption.
- Vegetables: Leafy greens like kale and spinach, cruciferous vegetables like broccoli and cauliflower, and root vegetables like carrots and sweet potatoes. Minimally processed frozen options without additives are also great.
- Whole Grains: Brown rice, quinoa, oats, barley, and farro. Look for products labeled "100 percent whole grain".
- Legumes: Dried beans (black, kidney), lentils, chickpeas, and peas. Soaking and cooking dried legumes is ideal, though canned versions without excess sodium are acceptable.
- Nuts and Seeds: Almonds, walnuts, chia seeds, and sunflower seeds. Opt for raw or dry-roasted versions without added salt or sugar.
- Proteins: Unprocessed meats and poultry (grass-fed or pasture-raised if possible), fish, eggs, and tofu.
- Dairy: Minimally processed options like plain yogurt, cottage cheese, and cheese. Avoid versions with added sugars and artificial flavorings.
Wholefoods vs. Ultra-Processed Foods: A Comparison
This table highlights the key differences that define what counts as wholefood versus what doesn't.
| Feature | Wholefoods (Unprocessed/Minimally Processed) | Ultra-Processed Foods |
|---|---|---|
| Processing Level | Minimal alteration (washing, freezing, cooking). | Extensive alteration using industrial additives and techniques. |
| Ingredient List | Non-existent or very short, with recognizable ingredients. | Long list of complex, unfamiliar chemical-sounding ingredients. |
| Nutrient Density | High in natural vitamins, minerals, antioxidants, and fiber. | Low in essential nutrients; often contains 'empty calories'. |
| Additives | Few to no added sugars, salts, fats, or artificial flavors. | High levels of added sugars, sodium, unhealthy fats, and artificial additives. |
| Satiety | High fiber and nutrient content promote lasting fullness. | Can lead to overeating due to concentrated calories and low nutrient value. |
| Shelf Life | Shorter shelf life due to minimal preservation. | Extended shelf life thanks to preservatives and synthetic ingredients. |
How to Incorporate More Wholefoods into Your Diet
Integrating more wholefoods doesn't have to be a complete overhaul. Small, consistent changes can make a big impact on your health.
- Shop the Perimeter: The outer aisles of the grocery store typically contain the freshest, whole foods like produce, eggs, and lean meats.
- Read the Label: Check the ingredient list and prioritize products with fewer, more recognizable ingredients. Be wary of marketing claims like "all-natural" or "fat-free," as these can be misleading.
- Make Simple Swaps: Swap sugary breakfast cereals for steel-cut oats with berries. Replace white bread with 100% whole grain bread. Choose whole fruits instead of fruit juice.
- Embrace Home Cooking: Cooking meals from scratch gives you full control over the ingredients, preventing the addition of excessive salt, sugar, and unhealthy fats common in pre-made foods.
- Plan Ahead: Meal prepping can help with busy schedules. Cooking large batches of wholefood-based meals like chili or soup and freezing them can provide convenient and healthy options.
- Choose Wisely: When buying canned or frozen products, opt for options with no added ingredients. Look for canned vegetables and beans with "no sodium added" or "low sodium" labels, and canned fruit packed in 100% juice instead of syrup.

Conclusion: Embracing a Wholefood-Centric Lifestyle
Understanding what counts as wholefood is the first and most crucial step towards making more informed and health-conscious dietary decisions. By prioritizing foods that are as close to their natural state as possible and minimizing your intake of ultra-processed items, you can dramatically increase your intake of vital nutrients like fiber, vitamins, and minerals. This approach to eating is not a restrictive fad diet, but a sustainable, long-term lifestyle choice that supports overall health and well-being. Start small with simple swaps and focus on progress over perfection. Your body will thank you for it.
