Removing animal foods changes where some nutrients come from. Replace excluded foods deliberately rather than simply taking them off the plate.
Vegetarian
Use legumes, soy foods, wholegrains, nuts and seeds, plus eggs and/or dairy where included. Check iron and B12 rather than assuming they are automatically covered.
Vegan
Build around legumes, tofu, tempeh, wholegrains, nuts, seeds, fruit, vegetables and fortified foods. Keep vitamin B12 coverage deliberate and reliable.
Pescatarian
Use fish and seafood alongside a varied plant-food base. Seafood can contribute protein, EPA/DHA, B12 and iodine.
Across all three
Keep the foundation varied: legumes, wholegrains, nuts, seeds, fruit and vegetables, with appropriate alternatives for foods that are excluded.
- Include a dependable protein source across meals.
- Choose wholegrains, legumes, nuts, seeds, fruit and vegetables regularly.
- Check fortification when milk alternatives are a major dairy replacement.
- Review B12, iron, iodine, omega-3, calcium, vitamin D and zinc against the foods actually eaten.
Bottom line: “Plant-based” describes the direction of the diet. Nutritional adequacy still depends on the details.
