The Sustainable EATLancet Diet

What is the EATLancet Diet?

The EATLancet Commission, a collaboration of nutrition and environmental scientists, released a universal reference diet in 2019. The aim was to define a dietary pattern that can nourish a growing global population while staying within planetary boundaries. Often called the planetary health diet, it combines evidencebased nutrition recommendations with climatefriendly food choices.

Core Principles

• Plantcentric: At least half of the plate should be fruits, vegetables, legumes, nuts and whole grains.
• Limited animal source foods: Modest portions of fish, poultry and dairy; red meat and processed meat are restricted.
• Low added sugar and refined grains: No more than 5% of daily calories from added sugars.
• Healthy fats: Emphasis on unsaturated oils (e.g., olive, rapeseed) and nuts; minimal saturated fat.
• Sustainability constraints: Food production must stay within safe limits for land use, freshwater, biodiversity loss and greenhousegas emissions.

Health Benefits

Adhering to the EATLancet diet is associated with a reduced risk of major noncommunicable diseases. Studies suggest:

The diet provides adequate protein, essential micronutrients and fiber while limiting saturated fat and sodium, which together support heart health, weight management and gut microbiome diversity.

Environmental Impact

When compared with typical Western diets, the reference diet can:

• Cut greenhousegas emissions by 2030%.
• Reduce land use for food production by up to 50%.
• Lower freshwater withdrawals by roughly 30%.
• Mitigate biodiversity loss by decreasing pressure on forests and marine ecosystems.

These figures stem from the diets lower reliance on resourceintensive animal products and its emphasis on locally sourced plant foods.

Practical Tips to Adopt the Diet

1. Start with a plantbased base. Fill half your plate with vegetables and legumes before adding any animal foods.
2. Choose whole grains. Swap white rice, refined pasta or bakery items for brown rice, quinoa, oats or wholewheat breads.
3. Limit red meat. Aim for 100g cooked red meat per week; replace with beans, lentils or tofu.
4. Eat fish responsibly. Prefer smallscale, lowbycatch species and keep intake to two servings per week.
5. Include nuts and seeds daily. A small handful (30g) supplies healthy fats and protein.
6. Reduce processed foods. Cut out sugary drinks, packaged snacks and readymade meals.
7. Season with herbs. Use spices, fresh herbs and citrus instead of excess salt.
8. Shop locally. Choose seasonal produce and support local farmers markets to cut transport emissions.
9. Plan meals. Weekly planning reduces waste and helps keep portions in line with recommendations.
10. Track progress. Simple apps can monitor fruit/vegetable servings, meat intake and carbon footprint.
