Vegan diets are a type of vegetarian diet, where only plant-based foods are eaten. They differ to other vegetarian diets in that no animal products are usually consumed or used. Despite these restrictions, with good planning it is still possible to obtain all the nutrients required for good health on a vegan diet.

Follow the food group recommendations for your age, sex, and activity level to get the right amount of food and the variety of foods needed for nutrient adequacy.

Healthy Eating Tips for Vegetarians
The National Health and Medical research Council of Australia
Alternatives to animal foods include nuts, seeds, legumes, beans and tofu. For all Australians, these foods increase dietary variety and can provide a valuable, affordable source of protein and other nutrients found in meats. These foods are also particularly important for those who follow vegetarian or vegan dietary patterns. Australians following a vegetarian diet can still meet nutrient requirements if energy needs are met and the appropriate number and variety of serves from the Five Food Groups are eaten throughout the day. For those eating a vegan diet, supplementation of B12 is recommended.
