Vegetarian eating is one of the most popular dietary choices in the UK, and for good reason — it's associated with better heart health, lower cholesterol, and reduced risk of type 2 diabetes. With eggs and dairy available, getting complete nutrition is straightforward. The challenge, as with any diet, is variety and planning ahead so you're not reaching for the same few meals week after week.
Types of vegetarian diet
Lacto-ovo vegetarian (the most common) includes dairy and eggs but no meat or fish. Lacto-vegetarian includes dairy but not eggs. Ovo-vegetarian includes eggs but not dairy. Pescatarian diets include fish — technically not vegetarian, but often grouped nearby. This guide focuses on lacto-ovo vegetarian, the most widely practised form.
Key nutrients for vegetarians
Most vegetarians get adequate nutrition easily, but a few nutrients deserve attention. Iron from plant sources (non-haem iron) is less well-absorbed than from meat — pair iron-rich foods with vitamin C to improve uptake. Zinc is found in legumes, nuts, seeds, and whole grains. Omega-3 fatty acids are available from eggs, walnuts, flaxseeds, and chia seeds. B12 is present in eggs and dairy, but supplementation is worth considering. Calcium is abundant in dairy, but also in fortified plant milks, broccoli, and almonds.
Best vegetarian protein sources
Eggs are one of the most complete protein sources available. Greek yoghurt and cottage cheese are excellent. Legumes — lentils, chickpeas, and beans — are protein powerhouses. Cheese, particularly hard cheeses, provides concentrated protein. Tofu, tempeh, and seitan work well in place of meat. Quinoa is the only plant grain containing all essential amino acids.

Meal prep strategies for vegetarians
Vegetarian cooking lends itself brilliantly to batch cooking. A big pot of lentil soup, a grain salad, roasted vegetables, and boiled eggs at the start of the week gives you building blocks for multiple meals. Legumes freeze well — cook a large batch and freeze in portions. Frittatas and egg muffins are versatile, portable, and use up leftover vegetables.
