From Roots to Fruits: How Trees Support Sustainable Diets
This year, as we observe National Nutrition Month 2025 with the theme “Ek Ped Maa Ke Naam,” we are reminded of the selfless, nurturing role that trees play in our lives—just like mothers. From their roots deep underground to the fruits they bear above, trees provide us with nutrition, resilience, and sustainability. They are the guardians of ecosystems and the silent providers of food security. Understanding the importance of trees in supporting sustainable diets is not only an environmental duty but also a celebration of the nourishment that connects nature to human health.

Roots – The Foundation of Life

Roots are the hidden lifelines of trees, storing energy and absorbing nutrients from the soil. Edible roots such as carrots, beets, radish, and turnips are loaded with dietary fiber, Vitamin A (beta-carotene), folate, potassium, and magnesium. These nutrients improve vision, support gut health, regulate blood pressure, and prevent anemia. Moreover, root-based foods are seasonal, locally available, and require fewer resources, making them sustainable choices for daily diets.

Leaves – Green Nutrient Powerhouses

Leaves are often called the “green pharmacy” of nature. Moringa, spinach, curry leaves, and drumstick leaves are rich in iron, calcium, Vitamin K, Vitamin C, chlorophyll, and phytonutrients. They support hemoglobin production, bone strength, blood clotting, and immunity. Moringa, in particular, is considered a superfood for its high protein and micronutrient density. Cultivating and consuming leafy parts of trees enhances diet diversity while maintaining ecological balance.

Flowers – Delicate Sources of Wellness

Many flowers are edible and hold significant nutritional and medicinal value. Banana blossoms are rich in fiber, Vitamin E, and antioxidants, helping manage diabetes and hormonal health. Pumpkin and hibiscus flowers are also consumed in Indian households, providing Vitamin C and phytochemicals that aid digestion and protect against oxidative stress. Incorporating edible flowers into meals not only adds variety but also connects traditional knowledge with modern nutrition practices.

Seeds & Nuts – Tiny Nutrient Treasures

Seeds and nuts from trees are compact reservoirs of energy. Almonds, walnuts, cashews, and pumpkin seeds are abundant in omega-3 fatty acids, protein, Vitamin E, magnesium, and zinc. They support brain health, improve heart function, enhance skin health, and provide satiety. Seeds like flax and sunflower are also crucial for hormone balance and reducing inflammation. Because they are non-perishable and nutrient-dense, nuts and seeds are a sustainable way to meet dietary needs across seasons.

Bark & Stems – Hidden Healers

Though often overlooked, the bark and stems of trees have profound health benefits. Cinnamon bark is a natural antidiabetic spice, supporting blood sugar control. Neem bark has antimicrobial properties, while sugarcane stem provides quick energy through natural sugars. Many tree-derived extracts are also used in Ayurvedic and herbal medicine to strengthen immunity, heal wounds and promote longevity. These parts demonstrate how trees extend their healing touch far beyond the plate.

Fruits – The Harvest of Health

Fruits are the most celebrated gifts of trees. Mango, guava, jackfruit, amla and coconut are traditional nutrition powerhouses in India.

  • Mango – rich in Vitamin A & C, supports vision and immunity.
  • Guava – an excellent source of Vitamin C and fiber, aids digestion and boosts immunity.
  • Amla (Indian gooseberry) – one of the richest sources of Vitamin C, acts as a strong antioxidant.
  • Jackfruit – provides fiber, Vitamin B6, and potassium, useful in heart health and satiety.
  • Coconut – offers healthy fats, electrolytes and lauric acid, promoting hydration and energy.

Fruits not only nourish but also provide hydration, prevent chronic diseases and improve overall vitality.

Trees as Pillars of Sustainable Diets

Beyond food, trees support sustainable diets by conserving soil, improving groundwater recharge, absorbing carbon dioxide, and fostering biodiversity. Practices like agroforestry—growing crops alongside trees—improve yields, reduce dependency on synthetic fertilizers and help communities withstand climate change.

          In Indian culture, trees have always been revered as mothers. The banyan tree shelters, the coconut sustains, and the neem heals. By dedicating a tree “Maa Ke Naam,” we honor both our mothers and Mother Earth—acknowledging their nurturing role in sustaining life and health.

A Call to Action

This National Nutrition Month, let us pledge to plant and protect nutrition-rich trees—mango, amla, moringa, drumstick, jackfruit, and many more. Every tree is a legacy of nourishment, resilience, and sustainability. By valuing trees from roots to fruits, we not only enrich our diets but also secure the health of future generations.

Just as a mother gives without expecting, trees nourish silently. Let us celebrate this bond by dedicating a tree “Maa Ke Naam” and creating a greener, healthier tomorrow.
