Vegan eating—no meat, fish, dairy, eggs, or honey—can be complete and healthful, but it asks for more attention than vegetarian eating. A few nutrients simply aren’t reliably available from plants alone, and pretending otherwise does no one any favors. Here’s the honest, practical picture.
The non-negotiable: If you eat fully vegan, you need a reliable source of vitamin B12—a supplement or consistently fortified foods. This isn’t optional, and it’s the one place where “just eat whole foods” isn’t enough.
The Nutrients That Need Real Attention
Vitamin B12 (essential supplement)
B12 isn’t reliably present in plant foods. Every credible vegan health authority recommends a B12 supplement or consistently fortified foods. Deficiency develops slowly and can cause serious, sometimes irreversible harm—so this one is genuinely important.
Omega-3 (EPA/DHA)
Plant omega-3 (ALA, from flax, chia, walnuts) converts poorly to the EPA and DHA your body uses most. An algae-based omega-3 supplement provides these directly and is the vegan-friendly equivalent of fish oil.
Protein
Very doable from legumes, soy foods, seitan, nuts, seeds, and whole grains—but it takes more intention without dairy and eggs. Eat a variety across the day. See The Protein Question.
Vitamin D
Hard to get from food for anyone; harder still without fortified dairy. Consider a vegan D supplement, especially in winter or at northern latitudes.
Calcium Without Dairy
Fortified plant milks, tofu set with calcium, leafy greens (kale, bok choy), tahini, and almonds. It takes planning, but it’s achievable.
Iron & Zinc
From legumes, whole grains, nuts, and seeds—pair iron foods with vitamin C to boost absorption, just as vegetarians do.
Well-Planned Vegan Eating Is Adequate
The Academy of Nutrition and Dietetics recognizes that well-planned vegan diets are healthful and appropriate for all stages of life—with the clear caveat that certain nutrients, B12 above all, require supplementation or fortified foods. “Well-planned” is doing real work in that sentence.

The Vegan Lens
Recipes tagged 🌿 Vegan contain no animal products at all. Every vegan recipe is also vegetarian (and almost always plant-forward), so it carries those tags too.
A note on your health: This page is educational, not medical advice. Everyone’s body is different, and conditions vary widely from person to person. Use this as a starting point for conversations with a doctor or registered dietitian you trust—not as a replacement for the care they provide. A fully vegan diet is the one dietary change we’d most strongly encourage you to plan with a doctor or registered dietitian—especially to set up B12 and to check iron and vitamin D over time.
