Vegetarian

Vegetarian refers to a diet that is predominantly based on plant foods. There are different types of vegetarian diets in which different levels of animal foods may be included. For example, a vegan diet contains no foods of animal origin, lacto-vegetarians include dairy products and ovo-lacto-vegetarians include dairy products, honey and eggs but avoid meat, chicken and fish.

Vitamin A

Vitamin A is found in animal foods including liver, dairy products, egg yolk and some fatty fish. Orange and yellow coloured fruit and vegetables (e.g. mangoes, carrots) contain carotenoids such as beta-carotene which are converted into vitamin A in the body. Vitamin A plays an important role in vision and growth and beta-carotene acts as an antioxidant to help protect against free radical damage.

Vitamin B Group

The B group vitamins (B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6, B12, folate and biotin) are found in meat, poultry, wholegrain products, dairy products, eggs, green leafy vegetables, nuts and seeds. Their main role in the body is in energy metabolism.

Vitamin C

Vitamin C plays a role in ensuring healthy connective tissue such as skin and cartilage. Vitamin C is also an antioxidant and can be found in a wide range of fruit and vegetables.

Vitamin E

The main role of Vitamin E in the body is as an antioxidant. Vitamin E protects many substances from oxidation but is particularly important for maintaining the stability of cell membranes by protecting them from free radical damage. Good sources of vitamin E include almonds, peanuts and soy bean oil.

Vitamins

Vitamins are essential micronutrients that are used in the body for a variety of processes. They are classified into two groups - fat soluble and water soluble. The fat soluble vitamins are vitamins A, D, E and K. The B group vitamins (B1, B2, B3, B12), folate, biotin and vitamin C are water soluble vitamins.
