Vegan dietitian’s edamame guacamole could be the ultimate longevity-boosting recipe

If you’re hunting for a supercharged dish that doesn’t skimp on taste, registered dietitian and vegan chef Nisha Melvani might have just the thing. In a recent YouTube video, Melvani unveiled what she calls “possibly the healthiest meal on the planet”—a creamy edamame guacamole served with antioxidant-rich purple sweet potato.

Melvani, who holds a Master’s in Nutrition from Columbia University and is the author behind Cooking for Peanuts, crafted this recipe with one clear goal: boosting health span and promoting longevity. “Maybe it’s because I’m turning 50 soon, or maybe it’s the food scientist in me,” she said, “but I’m on a mission to create delicious tasting foods that promote long life and vibrant health.”

What’s in this green-and-purple powerhouse?

The centrepiece is her five-minute edamame guacamole, made with creamy avocado, nutty tahini, garlic, and protein-packed edamame. The result is a vibrant, satisfying dip that’s rich in fibre, healthy fats, plant protein, and antioxidants.

She pairs the dip with roasted or steamed purple sweet potato—a colourful root vegetable celebrated for its high levels of anthocyanins, compounds known to support brain function, reduce inflammation, and boost heart health.

“It’s not just about being healthy,” Melvani insists. “Food should also be enjoyable. And I really enjoy this.”

The recipe is versatile too—perfect as a dip, spread, or side to your favourite meals. Whether you’re looking to refresh your lunch routine or add more whole foods to your diet, this combo is simple, satisfying, and seriously nutritious.
