  • Vegan (or strict vegetarian) who consume only plant-based foods and exclude all animal products

  • Ovo-lacto-vegetarian who consumes plant-based foods, eggs and milk products

  • Lacto-vegetarian who consumes plant-based foods and milk products

  • Ovo-vegetarian who consumes plant-based foods and eggs

  • Pescatarian who consumes plant-based foods, fish, seafood, egg and milk products

  • Pollo-vegetarian who consumes chicken, plant-based foods, fish, seafood, egg and milk products

  • Semi-vegetarian who avoids animal products on some days

What makes up a balanced vegetarian diet?

A vegetarian diet is generally low in saturated fat and cholesterol, and high in fibre and phytochemicals. Adopting a vegetarian diet has been shown to reduce risks of obesity, heart disease, hypertension, type 2 diabetes and certain cancers such as breast, colorectal and prostate cancers. However, as with all diets, it is important to ensure that the food consumed is able to provide for our daily nutritional needs.

A well-planned vegetarian diet would comprise a variety of vegetables, fruits, whole grains, legumes, nuts and seeds. Apart from these foods, individuals should also include dairy products like milk, cheese and yoghurt, if possible. This helps to ensure that the diet provides adequate nutrition to support good health for people of all ages.

On the other hand, a poorly planned vegetarian diet may lack many important nutrients, including protein, iron, Omega-3 fatty acids, calcium and vitamin B12. Individuals may consider consulting a medical doctor to seek advice for starting on supplements if they are unable to meet their daily nutrient requirements through diet alone.

Going vegetarian the healthier way (5 tips)

1. Start slow

Consider having vegetarian meals one day per week, such as ‘Meatless Monday’, before increasing the frequency gradually. A sudden drastic increase in our intake of fruits and vegetables may result in bloating, gas and stomach cramps as undigested fibre ferments in the large intestine.

2. Balance is key

Refer to the Health Promotion Board (HPB) ‘My Healthy Plate’ to achieve a balanced diet. Fill half of your plate with a variety of fruits and vegetables, a quarter with beans, legumes or soy products and another quarter with whole grains such as brown rice or starchy vegetables.

3. Introduce variety

Meet your nutritional needs with a wide variety of foods. For example, legumes (such as dried beans, peas and lentils) and soy products (such as tau kwa) are sources of plant-based protein, calcium and iron. Nuts and seeds (such as almonds, walnuts, flaxseed, chia seed) provide essential fatty acids, calcium, iron and B vitamins. Green leafy vegetables are good sources of iron, calcium and vitamin C, and fruits are generally rich in Vitamin C.

Having a variety of foods can help you enjoy your meals more, which makes going vegetarian more sustainable in the long run.

4. Fresh is best

Choose whole, unprocessed or natural foods and minimise your intake of highly processed foods. Also, select low fat options such as low fat milk.

5. Remember the basics

While choosing the right food is important, the method of preparation is also key. Opt for healthier cooking methods like steaming, grilling or baking instead of deep frying.
