The first time my coach encouraged me to eat more whole foods I assumed she was talking about the grocery store. I quickly learned that whole foods are foods are fresh fruits and vegetables, whole grains, lean meats, legumes, nuts, and seeds. Unlike processed products that often contain refined sugars and preservatives, whole foods provide nutrients in their purest form, making them a foundation of a healthy diet.

Let’s talk about what whole foods are and why we should incorporate more of them into our diet.

What Are Whole Foods?

At the most basic level, whole foods are foods that are as close to their natural state as possible. They are minimally processed, free of artificial additives, and typically don’t come with a long list of ingredients.

Examples include:

• Fresh fruits and vegetables

• Whole grains like oats, brown rice, and quinoa

• Lean proteins such as chicken, fish, eggs, or beans

• Nuts and seeds

• Legumes like lentils and chickpeas

Whole foods are different from highly processed foods, which often contain added sugars, refined oils, preservatives, and artificial flavorings. For example, an apple is a whole food. Apple-flavored toaster pastries are not.

Why Whole Foods Are Recommended

1. Nutrient Density

Whole foods provide vitamins, minerals, fiber, and antioxidants that our bodies needs to function properly. Because they are not stripped of their natural components, they deliver far more nutrition per calorie than heavily processed alternatives.

For instance, eating an orange not only gives you vitamin C but also fiber, potassium, and flavonoids that work together to support immune and cardiovascular health.

2. Lower Risk of Chronic Disease

A growing body of research links diets rich in whole foods to a reduced risk of chronic illnesses. Studies suggest that eating plenty of fruits, vegetables, whole grains, and lean proteins can lower the risk of heart disease, type 2 diabetes, and certain cancers.

For example, a 2019 meta-analysis published in The Lancet found that higher fiber intake from whole food sources was associated with a 15–30% decrease in all-cause mortality, cardiovascular disease, and type 2 diabetes.

3. Improved Digestive Health

Whole foods, particularly fruits, vegetables, legumes, and whole grains, are high in dietary fiber. Fiber supports a healthy gut microbiome, regulates digestion, and can help prevent constipation. It also slows digestion, promoting steadier blood sugar levels and prolonged satiety.

4. Satiety and Weight Management

Whole foods are naturally more filling than processed foods. High-fiber and protein-rich options help regulate hunger hormones, making it easier to maintain a healthy weight. Contrast this with ultra-processed snacks that are engineered to be hyper-palatable and easy to overeat.

5. Reduced Intake of Additives and Hidden Calories

When you focus on whole foods, you naturally limit your intake of added sugars, trans fats, and sodium, all of which are linked to poor long-term health outcomes.

Unprocessed vs. Processed Foods: A Practical Look

It’s worth noting that “processed” doesn’t always mean “bad.” For example, frozen vegetables, plain Greek yogurt, or canned beans are processed but still excellent whole food options because they remain nutrient-dense and minimally altered.

The key is to recognize ultra-processed foods—packaged snacks, sugary drinks, processed meats, and fast foods—which tend to be calorie-dense but nutrient-poor.

How to Add More Whole Foods Into Your Diet

Start Small

You don’t need to overhaul your entire diet overnight. Begin by swapping one processed item with a whole food each day. For example, replace sugary breakfast cereal with overnight oats topped with fruit and nuts.

Build Your Plate Around Whole Foods

Think of protein, whole grains, and vegetables as the anchors of your meals. Add healthy fats like olive oil, nuts, or avocado to round things out.

Shop the Perimeter of the Grocery Store

Most whole foods—produce, meats, dairy, and grains—are located around the outside aisles of the store. Ultra-processed foods often fill the center aisles.

Read Labels

A good rule of thumb: if the ingredient list is long, unrecognizable, or includes lots of added sugars and preservatives, it’s likely not a whole food.

Meal Prep for Convenience

One of the biggest barriers to eating whole foods is convenience. Preparing meals and snacks ahead of time—such as cutting up vegetables, portioning nuts, or pre-cooking grains—makes it easier to choose healthier options.

How Much of Your Diet Should Be Whole Foods?

There’s no one-size-fits-all percentage, but many nutrition experts recommend aiming for at least 80% of your diet to come from whole food sources, leaving room for flexibility and enjoyment. This approach encourages a sustainable lifestyle rather than rigid rules.

Protein intake should still meet daily needs, typically ranging from 0.8 to 1.2 grams of protein per pound of body weight depending on activity level and goals. Choosing high-quality protein from whole food sources like chicken, fish, tofu, beans, or eggs will not only help with muscle repair but also improve satiety.

The Bottom Line: Why Whole Foods Matter

Whole foods aren’t about perfection or restriction. They’re about fueling your body with nutrient-dense, minimally processed options that support your long-term health. From better digestion and reduced chronic disease risk to easier weight management, the evidence is clear: the closer your food is to its natural state, the better it is for your health.
