How To Build A Nutritionally Solid Vegan Diet

The nutrients requiring the most deliberate attention

Vitamin B12 (essentially unavailable from plant sources without fortification), and often iron, zinc, calcium, and omega-3s require more careful planning on a fully vegan diet compared to one including dairy and eggs.

B12 as a genuine non-negotiable

Unlike most other nutrients that can be reasonably obtained through careful plant-based food choices, B12 essentially requires either fortified foods or direct supplementation for anyone following a strict vegan diet long-term.

Building complete protein through variety

Combining different plant protein sources across the day — legumes, grains, nuts, seeds — ensures a complete amino acid profile, even though individual plant proteins are often incomplete on their own.

Calcium sources beyond dairy

Sesame seeds, fortified plant milks, certain leafy greens, and tofu (if made with a calcium-setting agent) can provide meaningful calcium on a vegan diet, though typically require more intentional inclusion than a diet that includes dairy.
