And Healthy Eating
Habits
What is healthy food?Healthy eating means eating a
variety of foods that give you the nutrients you need to
maintain your health, feel good, and have energy. These
nutrients include protein, carbohydrates, fat, water,
vitamins, and minerals.
Proteins
Carbohydrates
Fats
Minerals
Vitamins
A balanced diet contains a range of nutrients, all of which
play an important part in keeping our bodies healthy. The
nutrients in our food are classified as proteins, fats,
carbohydrates, vitamins, minerals and fibre.
Protein is the main constituent of all body cells. It provides the material necessary for growth and the repair and maintenance of the body.
Protein is found in many of the foods we eat like cereals and
breads, milk and cheese, meats and eggs and fish. It is important to eat a variety of
these foods as the body needs a variety of proteins to do its
job.
Proteins
Fats Fats are a fuel to provide energy for our bodies. They also act as a layer on the
body for insulation, to keep out the cold and to protect
against injury. The chief sources are butter,
margarine, cooking oils as well as fats in foods such as
cheese, meats and snack foods. The surplus fat we
eat is converted into stored body fat, so it is important
not to eat too much fat.
Carbohydrates
Carbohydrates also act as a fuel to provide us with energy. Carbohydrates
occur as either starches or sugars. The most useful carbohydrates are those
found in cereal foods, such as breads, rice, pasta,
oats, and starchy vegetables like potatoes, dried beans and peas. Any surplass is converted by
the body and stored as fat.
Minerals Minerals are required in very small quantities per day, however they are essential for on-going health.
Some of the main ones are:Calcium – Iron – Phosphorus - Zinc
Vitamins Vitamins are highly
complex, and fragile, organic compounds
which are essential to maintain a healthy body. Small amounts must be
absorbed from food each day, as generally
they can't be synthesised by the
body.
Fiber Although fibre doesn't provide us
with energy or essential
nutrients, it provides the bulk
to carry the waste products of
digestion out of the body.
The Food PyramidA food guide pyramid is a pyramid shaped
guide of healthy foods divided into sections to show the recommended
intake for each food groupThe food pyramid tells people the proper amount of what type of thing to eat. They are Grains, Vegetables, Meat And Beans, Fruit, and Milk. The bigger the area for
each category, the more of it you should eat. The steps on the food pyramid
remind you that you also need to exercise
