Vegetables are one of the world’s most diverse food groups taking on many forms, colours, and have abundant health benefits. But are all of them equal? Should we eat them every single day? How do we tell which gives us the best nutrition?
Broadly speaking, a vegetable is defined as any edible part of a plant. One such part which is popular in Asian cooking is the green leafy vegetable. They are extremely low in calories (many have less than 30 kcal per 100 grams) and are a good source of fibre.
When choosing, go for dark-coloured leafy greens as they contain more phytochemicals which are beneficial for the body.
In addition to leaves, the flowers (example, broccoli, cauliflower, artichokes), roots (such as carrots and radishes), stems (like asparagus and celery) and pods (including edamame, long beans and snow peas) of plants are also eaten. There are also vegetables which come from the fruit part of the plant. These include the bitter gourd, cucumber, eggplant, and lady's fingers.
We should eat vegetables every single day. One serving of vegetables looks something like this:
The recommended intake of vegetables is two servings per day. This should be consumed while keeping in mind My Healthy Plate guidelines: fill a quarter of your plate with wholegrains, a quarter with proteins, and the remaining half with the recommended two servings of fruits and vegetables per day for a well-balanced meal.
Here are some tips to increase the amount of vegetables in your daily diet:
Salads are a fresh and healthy way to enjoy your greens, but be mindful about the amount of dressing you use, and aim for the non-fat or low-fat variety.
It is interesting, however, to note that oil-soluble vitamins such as carotenoids in carrots and lycopene in tomato are best absorbed with some dietary fat. A few drops of olive oil or canola oil in your salad will therefore aid in your body’s absorption of these nutrients, as well as make it taste better.
Besides eating vegetables raw, cooking your veggies can also bring on added benefits. Studies have shown that the process of cooking helps to break down tough outer layers and the cellular structure of many vegetables, making it easier for your body to absorb the nutrients.
As a rule of thumb, the lesser the exposure to high heat and water, the better for veggies to retain their nutrients. Microwaving, steaming and sautéing are generally safe bets for cooking your vegetables. Blanching (placing your vegetables into boiling water briefly) is another good option.
Remember not to boil your vegetables for too long as water soluble vitamins such as Vitamin C, B1 and folate can leach into the water. The exception to this rule is carrots, which display increased levels of beta carotene after boiling.
Vegetables also come in a multitude of colours. These colours are the result of phytochemicals
 and indicate several interesting properties.
Eating a variety of vegetables in different colours gives us a complete spectrum of vitamins and minerals. For example, the orange colour of carrots and capsicums are a result of carotenoids. These vegetables are high in vitamin A, which helps keep your immune system strong.
Red vegetables such as tomatoes are a result of the compound lycopene, which has strong antioxidant properties. And, green vegetables are high in folate and iron.
By being creative with how you plate your colourful vegetables, you can add spark to your children’s food, while providing them with optimum nutrition. Check out these interesting ideas for

Finally, do pair your daily two servings of vegetables with two servings of fruits. As a general guideline, your fruit and vegetable intake should consist of a variety of colours for maximum nutritional impact.
By eating widely, you will be able to benefit from the different vitamins and minerals which may not be found in just one fruit or vegetable. Replacing high-calorie foods with fruit and vegetables can also help you to maintain a healthy weight.
