Vegan Guide
Short answers to real-world questions about veganism — food, health, shopping, and everyday life.
On a varied diet (legumes, soy foods, grains), plant protein readily covers the need for all essential amino acids. As for soy — it is one of the best-studied topics in nutrition. Soy isoflavones differ in structure from human oestrogen, and meta-analyses do not show a negative effect on testosterone in men or a higher risk of hormone-dependent cancers in women. The myth that soy 'feminises men' came mainly from rodent studies using doses incomparable with a human diet.
Yes. The Academy of Nutrition and Dietetics and the NHS consider a well-planned vegan diet appropriate at every life stage, including pregnancy and childhood — with B12 supplementation.
No — in practice fortified breakfast cereals should not replace a dedicated vitamin B12 supplement. Treat them only as a welcome extra in a plant-based diet, not as its main, foundational source.
Unfortunately no — that is one of the more common myths. Fermentation is genuinely good for gut flora, but the bacteria that produce B12 in pickled foods usually do not make a form the human body can absorb. Rather than relying on cabbage or cucumbers, it is better to use a supplement or fortified foods — plant milks, breakfast cereals or nutritional yeast with added B12.
Tofu, tempeh and seitan are the three main plant-based meat alternatives. They differ in base ingredient, production method, texture and nutritional profile.
No, that is a myth. Plants contain protein; on an ordinary varied diet, protein deficiency is uncommon where food is available.
A single plant may be lower in some amino acids, but a day’s mix (grains + legumes, soy, quinoa) covers needs. The myth that rice and beans must share every spoonful is outdated.
They do not have to. Sources: nuts, seeds, avocado, olive oil, tahini, tofu. Watch omega-3 (ALA from flax, chia, walnuts) and optionally algal DHA/EPA.
Absorption can be lower because of phytates, but legumes, nuts, seeds, tofu and whole grains cover needs on a varied diet. Soaking and fermentation help.
Not a pile. B12 is practically required (supplement or fortification). The rest (D, iodine, DHA, iron) depends on the diet, latitude and bloodwork — as it does for non-vegans.
Yes. B12 is not reliably present in unfortified plant foods. Reliable sources are a supplement and fortified foods (some plant drinks, cereals, fortified nutritional yeast).
