Make easy and responsible choices: A guide to sustainable diets

In a world full of big environmental problems, it's really important that we change the way we think about food. It's not just about eating to stay healthy and happy; it's also about realizing that the choices we make about what we eat can have a big impact on the Earth.

That's where sustainable diets come in. They're all about finding a balance between what's good for us and what's good for the planet. In this article, we'll explore what sustainable diets are, learn how to plan one and discover some foods and practices that can help us make a positive difference every day. It's time to start a journey toward a healthier planet!

What Are Sustainable Diets?

A sustainable diet can be defined as a way of eating that promotes both personal health and the health of the planet. It takes into account the social, economic, and environmental aspects of food production and consumption. Rather than focusing solely on calories or nutrients, a sustainable diet encourages mindful choices that minimize the negative impact on the environment while maximizing our well-being.

Indeed, the World Health Organization has found that at present times, global food production is responsible for “two-thirds of water use, is the leading cause of deforestation (in turn, decreasing biological diversity) and produces high levels of greenhouse gases – constituting about 20-30% of all such emissions.” (WHO)

Let’s look at an example.

What’s an Example of a Sustainable Diet?

One example of a sustainable diet is the "plant-forward" approach. It places plant-based foods at the center of the plate while still allowing for small amounts of animal products, such as fish, poultry, or dairy, if desired. By emphasizing fruits, vegetables, whole grains, legumes, and nuts, this diet promotes a wide range of essential nutrients while reducing the environmental strain caused by animal agriculture.

4 Thriving Sustainable Diets

When it comes to sustainable diets, it is important to rely on scientific research and data to guide our choices. Fortunately, several well-researched dietary patterns have emerged as powerful choices for both personal health and the environment.

1. Mediterranean Diet

The Mediterranean diet has been extensively studied and consistently shown to have numerous health benefits while being environmentally sustainable. (National Library of Medicine). This dietary pattern emphasizes whole foods such as fruits, vegetables, whole grains, legumes, nuts, and seeds. Furthermore, MedDiet emphasizes seasonality, biodiversity, food varieties, and buying local and fresh products. It also includes moderate consumption of fish, lean poultry, and dairy products, while minimizing red and processed meats. The Mediterranean diet is associated with reduced risks of heart disease, certain cancers, and overall mortality. Furthermore, its emphasis on plant-based foods and avoidance of resource-intensive meats makes it environmentally friendly.

2. Plant-Based Diet

Numerous studies have highlighted the health benefits and environmental sustainability of plant-based diets. These diets primarily focus on plant-derived foods, including fruits, vegetables, whole grains, legumes, nuts, and seeds, while minimizing or excluding animal products. Research indicates that well-planned plant-based diets can provide all the necessary nutrients while reducing the risk of chronic diseases such as obesity, type 2 diabetes, and heart disease. Plant-based diets also have a lower carbon footprint compared to diets heavy on animal products, making them a sustainable choice for both personal and planetary health.

3. Flexitarian Diet

A flexitarian diet is a flexible approach that combines the principles of plant-based eating with the occasional inclusion of small amounts of meat, fish, or poultry. This approach encourages a primarily plant-centered diet while allowing for flexibility and personal preferences. Flexitarians reap the benefits of plant-based eating, including reduced risks of chronic diseases and a lighter environmental footprint, while still enjoying the occasional inclusion of animal products. The flexibility of this approach makes it accessible to a wider range of individuals and facilitates long-term adherence.

4. DASH Diet

The Dietary Approaches to Stop Hypertension (DASH) diet is not only effective in reducing blood pressure (National Heart, Lung and Blood Institute) but also aligns with sustainability principles. The DASH diet emphasizes fruits, vegetables, whole grains, lean proteins, and low-fat dairy products while limiting saturated fats, added sugars, and sodium. This approach is associated with improved heart health and overall well-being. By focusing on plant-based foods, the DASH diet promotes environmental sustainability, as plant-based foods require fewer resources and produce fewer greenhouse gas emissions compared to animal-based foods.

5 Easy Ways To Plan Your First Sustainable Diet

Planning a sustainable diet starts with understanding your own dietary needs and preferences. Here are a few practical steps to get started:

Step 1: Increase plant-based foods: Incorporate a variety of fruits, vegetables, legumes, whole grains, and nuts into your meals. Experiment with new recipes and flavors to make this transition exciting and enjoyable.

Step 2: Choose sustainable protein sources: Reduce your reliance on animal proteins and opt for sustainable alternatives like beans, lentils, tofu, tempeh, and quinoa. If you consume animal products, prioritize those that are ethically and sustainably sourced.

Step 3: Minimize food waste: Plan meals ahead, create shopping lists, and store food properly to avoid unnecessary waste. Utilize leftovers creatively and compost food scraps whenever possible.

Step 4: Support local and seasonal produce: Buying locally grown and seasonal foods helps reduce transportation emissions and supports local farmers. Explore farmers' markets and community-supported agriculture (CSA) programs in your area.

Step 5: Opt for eco-friendly packaging: Choose products with minimal packaging or packaging made from sustainable materials. Consider buying in bulk or using reusable containers to reduce single-use plastics. Try these eco-friendly practices at your home.

What Are the Most Sustainable Foods to Eat?

Including the following foods in your sustainable diet can have a positive impact on the environment:

a. Leafy greens: Nutrient-rich and easy to grow, leafy greens like spinach, kale, and lettuce require fewer resources and have a smaller carbon footprint compared to animal-based alternatives.

b. Legumes: Beans, lentils, and chickpeas are not only excellent sources of protein but also promote nitrogen fixation in the soil, which reduces the need for synthetic fertilizers.

c. Seasonal fruits and vegetables: Choosing locally sourced and seasonal produce reduces the energy required for long-distance transportation and supports biodiversity.

d. Whole grains: Foods like quinoa, brown rice, and oats are high in fiber and require fewer resources compared to processed grains like white rice or refined wheat flour.

e. Sustainable seafood: When consuming seafood, choose options that are responsibly sourced and harvested to help protect marine ecosystems.

By embracing a sustainable diet, we can nourish our bodies and contribute to a healthier planet. Through conscious choices and small changes in our eating habits, and adopting these approaches, we can make informed choices that positively impact our well-being and contribute to a healthier planet. Remember, sustainability starts on our plates!
