As the world grapples with the dual challenges of ensuring human health and sustaining the environment, the concept of the Planetary Health Diet has emerged as a beacon of hope. Designed by the EAT-Lancet Commission, this diet aims to balance human nutrition needs with the imperative to protect our planet. Here are eight innovative ideas to incorporate the Planetary Health Diet into your life in 2024.
1. Embrace Plant-Based Proteins
One of the core principles of the Planetary Health Diet is the shift from animal-based to plant-based proteins. Legumes, nuts, and seeds are excellent sources of protein, offering numerous health benefits and a lower environmental impact compared to meat.
Why it matters: Plant-based proteins require significantly less land, water, and energy to produce. For example, producing one kilogram of lentils generates 0.9 kg of CO2 emissions, compared to 27 kg of CO2 for beef . Additionally, legumes are rich in fiber, vitamins, and minerals, which are essential for a balanced diet.
How to start: Incorporate a variety of legumes into your meals. Try chickpea curries, black bean salads, or lentil soups. Use nuts and seeds as snacks or add them to dishes for extra protein and healthy fats.
2. Prioritize Whole Grains
Whole grains are a staple of the Planetary Health Diet, providing essential nutrients and fiber. Unlike refined grains, whole grains retain their bran and germ, which are packed with vitamins, minerals, and antioxidants.
Why it matters: Whole grains contribute to better digestive health, reduce the risk of chronic diseases, and have a lower glycemic index compared to refined grains. Environmentally, they are more sustainable as they require fewer inputs and yield more food per unit area than many other crops.
How to start: Replace refined grains with whole grains such as brown rice, quinoa, barley, and oats. Start your day with a bowl of oatmeal, use quinoa in salads, or switch to whole grain bread and pasta.
3. Reduce Meat Consumption
Reducing meat consumption is a key component of the Planetary Health Diet. While meat can be part of a balanced diet, excessive consumption is linked to numerous health issues and significant environmental degradation.
Why it matters: The production of red meat, in particular, is resource-intensive and generates high levels of greenhouse gases. Reducing meat intake can lower the risk of heart disease, stroke, and certain cancers .
How to start: Implement “Meatless Mondays” or choose plant-based meals for several days each week. Explore meat alternatives like tofu, tempeh, and seitan. When you do eat meat, opt for smaller portions and prioritize sustainably sourced, lean meats such as chicken or fish.
4. Diversify Your Diet with Seasonal and Local Produce
Eating a variety of seasonal and locally produced fruits and vegetables supports both health and the environment. Seasonal produce is often fresher and more nutrient-dense, while local sourcing reduces the carbon footprint associated with transportation.
Why it matters: Consuming a diverse array of fruits and vegetables ensures a broad intake of essential nutrients and phytochemicals, which support overall health and disease prevention. Supporting local agriculture also fosters community resilience and reduces reliance on long-distance food supply chains.
How to start: Visit local farmers’ markets to discover seasonal produce. Plan meals around what’s in season, and experiment with new fruits and vegetables. Grow your own herbs and vegetables if possible.

5. Optimize Dairy Intake
While dairy products are a good source of calcium and vitamin D, their production has a notable environmental impact. The Planetary Health Diet recommends moderate consumption of dairy, focusing on sustainable choices.
Why it matters: Dairy farming is associated with high greenhouse gas emissions, water use, and land degradation. Reducing dairy intake and choosing sustainably produced options can mitigate these impacts.
How to start: Limit your dairy intake to one or two servings per day. Explore plant-based alternatives like almond milk, soy milk, and oat milk. When purchasing dairy, look for products labeled as organic or from pasture-raised animals, which typically have a lower environmental footprint.
6. Minimize Food Waste
Food waste is a critical issue, with significant implications for both the environment and food security. Approximately one-third of all food produced globally is wasted, contributing to unnecessary resource use and greenhouse gas emissions .
Why it matters: Reducing food waste can conserve resources, reduce emissions, and improve food availability. From an environmental standpoint, minimizing waste helps reduce the pressure on landfills and decreases methane emissions.
How to start: Plan your meals and shop with a list to avoid over-purchasing. Store food properly to extend its shelf life, and get creative with leftovers. Compost organic waste instead of sending it to the landfill. Educate yourself on portion sizes to prevent plate waste.
7. Choose Sustainable Seafood
Seafood can be a healthy part of the diet, but overfishing and unsustainable practices threaten marine ecosystems. The Planetary Health Diet advocates for the consumption of sustainably sourced seafood.
Why it matters: Overfishing depletes fish populations, disrupts marine food webs, and damages habitats. Sustainable seafood practices help maintain fish stocks at healthy levels and protect ocean biodiversity.
How to start: Look for certifications such as the Marine Stewardship Council (MSC) label, which indicates sustainably sourced seafood. Diversify your seafood choices to include species that are more abundant. Reduce your consumption of high-impact species like shrimp and tuna, and opt for smaller, lower-impact fish like sardines and mackerel.
8. Hydrate Sustainably
Staying hydrated is essential for health, but the choice of beverages can have environmental implications. The Planetary Health Diet promotes the consumption of water as the primary beverage.
Why it matters: Bottled water and sugary drinks contribute to plastic waste and have a significant environmental footprint. Drinking tap water reduces plastic pollution and the carbon footprint associated with bottling and transporting beverages.
How to start: Invest in a reusable water bottle and drink tap water or filtered water whenever possible. Limit your intake of sugary drinks and avoid single-use plastic bottles. Explore sustainable and low-impact alternatives such as homemade herbal teas and infusions.
Conclusion
The Planetary Health Diet offers a comprehensive framework for aligning our dietary habits with the goals of health and sustainability. By embracing plant-based proteins, whole grains, seasonal and local produce, and reducing meat and dairy consumption, we can make a positive impact on our health and the planet. Minimizing food waste and choosing sustainable seafood further enhances these benefits. As we look towards 2024, let’s commit to making mindful food choices that support a healthier, more sustainable future for all.
