There are more than 40 different kinds of nutrients in food and they can generally be classified into the following 7 major groups:
'Carbohydrates', 'Proteins', 'Fats', 'Vitamins', 'Minerals', 'Dietary Fibre', 'Water'.
Although each of the 7 major groups of nutrients perform different and have unique functions in our body, they are all essential because they work together and contribute to our good health.
Eating a healthy diet is not about strict limitations, staying unrealistically thin, or depriving yourself of the foods you love. Rather, it’s about feeling great, having more energy, improving your health, and boosting your mood.
Healthy eating doesn’t have to be overly complicated. If you feel overwhelmed by all the conflicting nutrition and diet advice out there, you’re not alone. It seems that for every expert who tells you a certain food is good for you, you’ll find another saying exactly the opposite. The truth is that while some specific foods or nutrients have been shown to have a beneficial effect on mood, it’s your overall dietary pattern that is most important. The cornerstone of a healthy diet should be to replace processed food with real food whenever possible. Eating food that is as close as possible to the way nature made it can make a huge difference to the way you think, look, and feel.
By using these simple tips, you can cut through the confusion and learn how to create and stick to a tasty, varied, and nutritious diet that is as good for your mind as it is for your body.
It’s important to eat the right amount of energy (measured in calories or kilojoules) to be able to carry out all your normal everyday activities. Even processes like breathing and thinking use up energy.
If you take in exactly what you use up, you're in energy balance – sometimes known as weight maintenance. Taking in more energy than you need leads to putting on weight, whereas taking in less than you need will cause you to lose weight.
The exact amount of energy you need will depend on many things including your age and how active you are. But in general, women need around 2,000 calories a day, and men around 2,500 calories. As well as supplying your body with energy, eating the right types of food in the right amounts can help look after your overall health.
