Sustainable Nutrition

Sustainable nutrition is an approach to eating that safeguards individual health and well-being while considering environmental, economic, and social sustainability. It is defined by the Food and Agriculture Organization (FAO) and the World Health Organization (WHO) as dietary patterns that are low in environmental impact, safe, equitable, accessible, and culturally acceptable.

Sustainable nutrition encompasses not only the foods consumed but also the processes of production, processing, distribution, consumption, and waste management. This approach integrates goals related to food security, biodiversity, cultural heritage, locality, economic sustainability, and public health. Sustainable nutrition aims to ensure that current and future generations have access to sufficient, balanced, and healthy foods while preventing nutrition-related chronic diseases and preserving natural resources.

Climate Change and Nutrition

Agriculture and food production account for approximately 30% of global greenhouse gas emissions and contribute to 80% of global deforestation. Seventy percent of global freshwater use is dedicated to food production. Climate change negatively affects agricultural output, leading to yield losses, reduced biodiversity, and declines in nutritional quality. Extreme weather events and climate fluctuations increase food insecurity, particularly among vulnerable populations.

The carbon footprint is an indicator used to measure greenhouse gas emissions resulting from food production and consumption processes. For example, producing 1 kg of beef generates approximately 99.48 kg of carbon dioxide equivalent emissions, while 1 kg of apples produces 0.43 kg and 1 kg of potatoes produces 0.46 kg. The water footprint represents the total volume of water used in food production and is classified into blue, green, and grey water.

Principles of Sustainable Nutrition

Sustainable nutrition includes the following principles:

• Minimizing environmental impacts during production
• Preventing food waste
• Balanced consumption of animal and plant-based foods
• Prioritizing local and seasonal foods
• Supporting sustainable agricultural practices
• Reducing environmental impacts of packaging and transportation
• Preserving cultural values and traditional eating habits

Sustainable Dietary Patterns

Mediterranean Diet: Emphasizes plant-based foods. Legumes, cereals, fruits, and vegetables are the core components. Red meat and processed foods are limited. Most fats come from olive oil. Dairy products, eggs, fish, and white meat are consumed in moderation. Its protective effects against heart disease, diabetes, cancer, and neurodegenerative disorders are scientifically proven.

DASH Diet: Focuses on vegetables, fruits, whole grains, low-fat dairy products, and low-sodium foods.

Vegetarian and Vegan Models: Limit animal-based foods and prioritize plant-based proteins. Dietary variety and essential micronutrients must be carefully planned.

Flexitarian Diet: Plant-based foods are prioritized, while animal-based foods are consumed in moderation.

New Nordic Diet: Prioritizes local and seasonal foods, limits processed foods, and aims for low environmental impact.

Sustainable Agriculture and Food Systems

Sustainable agriculture encompasses production methods that are ecologically, socially, and economically balanced. Agroecology organizes food production processes in an environmentally sensitive, economically viable, and socially equitable manner. Family farming is a fundamental component of agroecological practices. More than 90% of farms worldwide are family-run and provide 80% of total food production.

Industrial agricultural systems exert pressure on natural resources through monoculture farming, intensive livestock production, and contract farming. These systems harm the environment through fossil fuel use, chemical fertilizer and pesticide application, genetic modification, and high water consumption. Agroecological production increases agricultural productivity, reduces rural poverty, and slows climate change. According to European projections, transitioning to agroecological practices could reduce agricultural greenhouse gas emissions by 40% and contribute to biodiversity conservation.

Turkish Cuisine and Sustainable Nutrition

Traditional Turkish cuisine is well suited to sustainable nutrition due to its food diversity, low environmental impact, and high nutritional value. Dried legumes, bulgur, vegetables, and olive oil-based dishes are prioritized. Local herbs, spices, and plants are utilized. Traditional foods such as fermented beverages, bread, and tarhana reduce food waste and support cultural heritage preservation. The use of regional products and foods prepared through traditional methods supports economic and social sustainability.

Sustainable Shopping Strategies

• Preference should be given to local and seasonal foods over imported ones.
• Producer markets and organic markets should be supported.
• Foods produced through sustainable agricultural practices (such as organic or good agricultural practices) should be preferred, and labels on packaging should be checked.
• Natural or minimally processed foods should be chosen over processed and packaged foods.
• Foods should be purchased according to their seasonal availability.
• Geographically indicated and traditional products should be supported.
• Best-before and recommended consumption dates of foods should be monitored.
• A shopping list should be prepared before going out, and unnecessary purchases should be avoided.
• Foods with recyclable and environmentally friendly packaging should be preferred.
• Reusable cloth bags or specialized shopping bags should replace plastic bags and single-use paper bags.
• In daily eating habits, animal-based foods should be consumed within recommended amounts, and plant-based foods should be prioritized.
• Walking, cycling, or public transportation should be preferred over individual car use.

Sustainable Nutrition Recommendations by Food Group

Red Meat and Processed Products: Consumption should be limited, and processed meats should be avoided. Plant-based protein sources should be included in meals. Brands that prioritize animal welfare can be preferred.

Dairy and Dairy Products: Low-fat varieties should be consumed in recommended amounts. Plant-based milk alternatives can be used in moderation and should be planned with dietitian guidance.

Fruits and Vegetables: Local and seasonal varieties should be consumed, and proper storage conditions should be observed. Foods produced through sustainable agricultural practices should be preferred.

Fish and Seafood: Foods harvested through sustainable fishing methods and consumed in season should be preferred.

Plant Oils: Olive oil and other plant oils should be consumed in balance, replacing palm oil.

Cereals and Legumes: Local and seasonal varieties should be preferred. Dried legumes, bulgur, whole grains, and regional cereal products support food diversity and sustainability.

Food Safety and Waste Management: Foods should be purchased according to need, and best-before dates should be tracked. Leftover foods should be repurposed in other meals, and fermented or dried foods should be incorporated into consumption plans.

Shopping and Storage Strategies: Choosing seasonal foods, checking for sustainable agriculture labels on packaged foods, selecting recyclable packaging, preparing shopping lists, and avoiding excess food purchases strengthen sustainable nutrition practices.
