Why is water important?

Hi everybody today ill be telling why water is important

Water is vital to life. Without it we cannot survive for very long. We lose water from our bodies through urine and sweat, and we need to replace it regularly to prevent dehydration. It is recommended that we drink eight glasses of water a day. 

Our organs require water to function properly. 



Water regulates our body temperature-when we sweat the water evaporates from our skin and cools us down.
Water helps to remove waste products from our bodies. If these waste products are not removed they can release poisons , which can damage our organs or make us ill. 
We need water to help our bodies absorb nutrients, vitamins and minerals and help our digestive system. 
Water acts as a lubricant,helping our eyes and joints to work and stay healthy. 
Sources of water: 
drinks of all kinds of drinks  foods such as fruits,vegtetables,meat, eggs fibre

Minerals

Hi everybody today I will be telling you about minerals

There are 19 minerals in total, most of which our bodies need, in very small quantities, to function properly.

We need minerals to build our bones and teeth. Minerals help us to carry out bodily functions. Minerals help to control the levels of fluid in our bodies. I will now tell you about a few of the most important minerals for our bodies.

Calcium

We need calcium to:

build bones and teeth help our blood to clot help muscles to work. In order for our bodies to use calcium effectively they also need vitamin D.

Sources of calcium are:

milk and milk products green vegetables the bones of tinned oily fish  (e.g. sardines) drinking water wholemeal bread and white bread if calcium has been added.
iron

We need iron to build haemoglobin, which is a substance in our blood that transports oxygen and carbon dioxide around the body.

sources of iron include:

lean meat wholemeal flour offal (animals' internal organs, such as the heart, liver …

Why is protein important?

Hi everyone today ill be telling you why protein is important

Protein is an essential part of all living things. Every day our bodies carry out millions of tasks (bodily functions) to stay alive. We need protein so that our bodies can grow and repair themselves.

There are two kinds of protein:

Animal protein Vegetable protein.
The lifespan of the cells in our bodies varies from a week to a few months .As the cells die they need to be replaced .We need protein for our cells to repair and for new ones to grow.

We also use protein for energy. Any protein that is not used up in repairing and growing cells is converted into carbohydrate or fat.

What is protein?

Protein is made up of chemicals known as amino acids. The protein in cheese is different from the protein in meat because the amino acids are different. Some amino acids are essential to the body, so they must be included in a balanced diet. Ideally our bodies need both animal and vegetable protein so that we get all the amino acids we…

Why is Fibre important?

Hi everyone today ill be telling you why Fibre is important


Dietary fibre is a very important form of starch. Unlike other carbohydrates, dietary fibre cannot be digested and does not provide energy to the body.

However, dietary fibre is essential for a balanced diet because it:

helps to remove waste and toxins from the body and maintain bowel action

fruits and vegetables wholemeal and granary bread wholegrain cereals wholemeal pasta wholegrain rice pulses (peas and beans) and lentils.

Fats form an insulating layer under the skin and this helps to protect the vital organs and to keep the body warm. Fat is also needed to build cell membranes in the body.
