The **T. Colin Campbell diet** is essentially a **whole-food, plant-based (WFPB)** eating pattern developed and promoted by nutritional biochemist T. Colin Campbell, largely based on findings from his research in China and later summarized in The China Study.
At its core, it recommends eating **unrefined plant foods** and avoiding or minimizing all animal-derived and highly processed foods.
### Core principles
The diet emphasizes:
* **Whole plant foods**: vegetables, fruits, whole grains, legumes, nuts, and seeds
* **Very low to no animal products**: no meat, dairy, eggs, or fish
* **Low fat intake**: especially minimizing added oils and high-fat processed foods
* **Unprocessed or minimally processed foods**: food in its natural form rather than refined products
* **High carbohydrate intake (from whole plants)**: staples often include rice, potatoes, oats, beans, and corn
### What is avoided
* Meat, poultry, fish
* Dairy products (milk, cheese, yogurt, butter)
* Eggs
* Added oils (olive oil, coconut oil, etc., are often discouraged)
* Refined sugar and heavily processed packaged foods
* Highly refined grains (like white bread or white rice in stricter versions)
### Underlying idea
Campbell’s approach is based on the hypothesis that:
* Chronic diseases (heart disease, diabetes, some cancers) are strongly linked to **animal protein and high-fat diets**
* Whole plant foods may support better long-term health outcomes when they replace animal products
This perspective was heavily influenced by large-scale epidemiological research conducted in collaboration with institutions including Cornell University.
### In practice
People following this diet often eat meals like:
* Oatmeal with fruit and nuts
* Bean and vegetable stews
* Brown rice with lentils and greens
* Potato-based meals without added oil
* Smoothies made from fruits and leafy greens
### Important nuance
This is a **strict form of vegan diet**, but it’s more specific than general veganism because it also strongly emphasizes:
* “Whole foods” over processed vegan substitutes
* Low fat intake
* Minimizing added oils even if plant-based
