One of the reasons that we have so many problems controlling our weigh is because most of us have forgotten the true purpose of eating food.
We should not be eating food to give ourselves a passing pleasurable experience such as we may get when we eat some cheesecake or chocolate.
The purpose of digesting food is to give us enough energy and strength to get through the day.
Food consists mainly of protein, carbohydrates, fats and a small quantity of vitamins and minerals.
Food also contains water which is vital to the body as it provides the fluid to help the blood circulate around the body.
If you are going to adopt a healthy eating regime it is important that you understand the role that these main constituents fulfil.
Protein.
This come mainly from animals in the form of meat and should be eaten in moderation as it can contain a high level of saturated fats which can be harmful to you.
We all need some protein as it contains essential amino acids.
Protein can be obtained from plant foods if they are combined.
By combining pulses such as beans with grains and nuts you can provide your body with its required daily level of protein even on a vegetarian diet.
Carbohydrates.
All carbohydrates are sugars and as such are an excellent source of energy as they are converted by the body into glucose.
However, eating too many carbohydrates can affect the balanced of the body by upsetting your sugar levels.
This can result in a feeling of tiredness, mood swings and irritability.
Fats.
These represent a very concentrated source of energy.
They can be divided into two types saturated and unsaturated.
Saturated fats are normally solid at room temperature and include butter and margarine.
It is also found in meats, pies, biscuits and many processed foods.
Eating too much saturated fat can lead to raised cholesterol levels and an increased risk of high blood pressure and heart disease.
Unsaturated fats.
These are generally fluid at room temperature and can be found in vegetable oils such as sesame, olive and sunflower oils.
They can also be found in oily fish such as mackerel and sardines.
Unsaturated fats are considered to be much better for you than the saturated variety.
Water.
Some experts believe that a majority of the population are suffering from some level of dehydration.
It is recommended that we should all drink around 2 litres of water per day.
This can help keep energy levels up and help- reduce high blood pressure.
It is important to get the balance between all the constituents of your daily food right.
If you do this then you should be able to lead a healthy and active life.
