Across the animal kingdom, dietary habits are largely determined by genetic design. Carnivores like cats have short digestive tracts and thrive on raw meat. In contrast, primates—including chimpanzees—and herbivores have longer guts adapted to fiber-rich plant foods.
Interestingly, the digestive system of a chimpanzee closely resembles that of a human. Even pigs, whose gut structure is surprisingly similar to ours, can survive and thrive on a plant-only diet. This suggests that humans, too, can live healthfully on whole plant-based foods.
In fact, many populations around the world have demonstrated this. Large vegetarian communities in India and among the Seventh-day Adventists in the United States show remarkable health and longevity. Studies consistently find that plant-based eaters have lower rates of non-communicable diseases (NCDs) such as heart disease, diabetes, and certain cancers.
Fiber—found exclusively in plant foods—is essential for optimal digestion and nutrient absorption. Our human gut depends on it, yet it is absent in animal-based foods. This is one reason why plant-eating primates rarely suffer from chronic diseases.
Although humans have evolved to enjoy both raw and cooked food, our best health outcomes are seen when the diet remains largely plant-based. In contrast, populations that consume high amounts of animal products tend to experience more lifestyle-related illnesses.
In summary, the closer our diet is to that of our primate cousins—centred on whole, unprocessed plant foods—the more likely we are to enjoy a healthy and extended life.
A whole-food, plant-based plate features the following:
- Vitamin B (especially B9 and fortified sources of B12)
- Vitamin D (via sun-exposed mushrooms and fortified plant milk)
- Omega-3 fatty acids (chia seeds, flaxseeds, walnuts)
The plate includes:
- Dark leafy greens (spinach or kale) – for B vitamins
- Lentils and chickpeas – for B9 and protein
- Tempeh or nutritional yeast – for plant-based B12
- Sun-dried mushrooms – natural Vitamin D source
- Fortified almond milk – served in a small glass (for Vitamin D)
- Chia and flax seeds – sprinkled on top for Omega-3
- Avocado slices and walnuts – for healthy fats and Omega-3
- Sweet potatoes – for fibre and B vitamins
