Ask a Dietitian: Vegan vs. Ovo-Lacto Vegetarian — Which Makes Balanced Eating Easier?

The Question

Which is healthier and easier to keep nutritionally balanced — a fully vegan diet or an ovo-lacto vegetarian one (which includes eggs and dairy)?

The Dietitian's Answer

There's no absolute answer here — each approach comes with its own set of priorities. Because ovo-lacto vegetarians still eat eggs and dairy, nutrients like B12, vitamin D, and high-quality protein are relatively easier to obtain, making meal planning somewhat simpler. A fully vegan diet excludes all animal foods, so it requires more proactive use of fortified foods and supplements to cover nutrients like B12 and DHA — planning demands are higher, but with careful attention, a vegan diet can be just as well balanced.

What Both Approaches Have in Common

Whichever path you choose, whether the diet ends up balanced ultimately comes down to how varied the food choices are, whether total calorie intake is adequate, and whether key nutrients are proactively covered — not simply whether eggs and dairy are included:

• Vegans: with proper planning, nutritional status can match that of ovo-lacto vegetarians, but B12 and DHA must be actively supplemented
• Ovo-lacto vegetarians: have more natural sources available, but can still end up nutritionally unbalanced if they rely heavily on refined foods and neglect vegetables, fruits, and legumes

Neither Approach Is Set in Stone

Many people move flexibly between the two depending on their life stage — for example, choosing to reintroduce eggs and dairy temporarily during pregnancy to make planning easier. This kind of flexibility isn't a contradiction in itself; what matters is understanding your nutritional needs and the right supplementation strategy at each stage.

Advice for Anyone Torn Between the Two

Which approach to choose mostly comes down to personal values, lifestyle, and how easy each is to sustain. From a nutritional standpoint, both are viable, healthy ways of eating — what matters most is how well they're put into practice at the table each day.
