Vegetarianism: Pros and Cons

Edaku — Fri, 22 May 2026 09:00:00 +0300

Vegetarianism is one of the most established eating patterns, followed by millions of people worldwide, and there’s enough research on it to talk about real, measurable pros and cons rather than just personal conviction. As with most ways of eating, the outcome depends heavily on how the diet is actually structured, not just on the decision to skip meat.

What “vegetarian” actually covers

Vegetarianism comes in several forms: lacto-ovo vegetarians eat dairy and eggs, lacto-vegetarians eat dairy but not eggs, and strict vegetarians (vegans) exclude all animal products entirely. Most of the health research is based on the lacto-ovo version, which is generally considered the most balanced and the easiest to sustain in everyday life.

A fully plant-based diet can absolutely provide everything the body needs, but it does take a bit more deliberate planning than a diet that includes animal products. A handful of nutrients are either missing from plants entirely or harder to absorb from them, and knowing which ones matters more than counting every gram.

Vitamin B12 is the one non-negotiable

Vitamin B12 is really the only nutrient that’s practically impossible to get in reliable amounts from unfortified plant foods. It occurs naturally in animal products, and its presence in the plant world is scarce and inconsistent at best. That’s why the near-universal recommendation for vegans is to eat B12-fortified foods regularly — some plant milks, breakfast cereals, and nutritional yeast are fortified — or to take a supplement. B12 deficiency develops slowly, sometimes over years, but its effects on the nervous system and blood cell production are serious enough that this isn’t the nutrient to leave to chance.
