Should humans eat meat? It’s a question that sparks strong feelings. Some people argue that our bodies are better suited to plant foods; others point to the long history of humans eating meat. The truth is more nuanced than either side sometimes suggests.

What we know about human diets

Humans are able to digest both plant and animal foods. Evidence suggests our ancestors ate a wide variety of foods depending on where they lived, including plants, nuts, seeds, fish and meat. Today, people around the world thrive on very different diets.

The case for more plants

Many studies link diets rich in vegetables, fruit, beans, whole grains, nuts and seeds with better health. Plant foods provide fibre, vitamins, minerals and other helpful compounds. Eating more plants is also often kinder to the environment.

Meat can be part of a healthy diet

Many people include meat as part of a balanced diet. Choosing smaller portions, lean cuts and less processed meat, and filling more of your plate with plants, is one approach many dietary guidelines suggest.

If you eat a fully plant-based diet

A well-planned plant-based diet can provide most of what you need. One nutrient needs special attention: vitamin B12, which isn’t reliably found in plant foods. If you eat no animal products, choose fortified foods or a B12 supplement, keeping within the dose on the label. Iron, iodine, calcium and omega-3 fats are also worth keeping in mind.

Respecting different choices

People choose what to eat for many reasons: health, culture, ethics, budget and taste. There’s no need to judge yourself or others for different choices.
