MAKANAN SEIMBANG

Makanan seimbang merupakan makanan yang harus dimakan untuk memastikan tubuh badan seseorang berfungsi dengan normal. Makanan seimbang seharusnya memberikan kita tenaga. makanan yang mencukupi, karbohidrat, protein dan lemak secara optimum, kandungan fiber yang mencukupi dan kandungan bahan galian, vitamin dan asid lemak.Makanan yang memberi tenaga dapat membina badan, dan dapat menjauhi kita daripada mendapat penyakit. Amalan pemakanan sihat adalah satu faktor yang penting ke arah kesihatan sekeluarga dan seharusnya dipupuk dari rumah. Selain daripada menyelerakan dan mampu dibeli, makanan yang dikongsi bersama sekeluarga mestilah berkhasiat dan sihat. Makanan seimbang seharusnya memberi :

i. Tenaga makanan yang mencukupi
ii. Karbohidrat, protein dan lemak secara optimum.
iii. Kandungan fiber yang mencukupi
iv. Kandungan bahan galian, vitamin dan asid lemak.

Makanan ini terdiri dari tiga kumpulan iaitu makanan yang memberi tenaga, menjauhi dari penyakit dan membina sel-sel dan tisu tubuh.

A. Makanan yang memberi tenaga
Di Malaysia tenaga 50-60% penduduk didapati daripada nasi. Namun begitu makanan lain yang menghasilkan tenaga termasuk semua jenis bijirin seperti jagung, gandum, beras, bali, ubi keledek, keladi, ubi kayu, kentang dan lain-lain. Makanan lain yang menghasilkan tenaga �dalah makanan yang mengandungi gula seperti gula pasir, sirap, jem dan madu.

B. Makanan membina badan
Protein ah�la makanan membina badan. Protein membina sel-sel atau jeringan tisu dalam badan kita. Punca protein adalah daripada ikan, ketam, kepah, sotong, ayam, itik, dan lembu. Kekurangan sumber protein boleh membantutkan pertumbuhan seseorang termasuk pembentukan otot. Kekurangan protein juga mempengaruhi pembentukan darah dan ini menyebabkan badan menjadi lesu.

C. Makanan menjauhi penyakit
Makanan jenis ini merupakan makanan yang membekalkan tubuh dengan bahan-bahan yang mengekalkan semua perjalanan organ di dalamnya. Ia mencegah tubuh daripada menghidap penyakit. Makanan jenis ini meliputi sayur-sayuran dan buah-buahan.

A Balanced Diet

You must have carbohydrate, protein, fat, vitamins, minerals salts and fibre in the correct proportions. If there is not enough protein, you will not be able to grow properly and you will not be able to repair yourself i.e. wounds will not heal properly. If you do not have enough energy containing foods you will feel very tired, you will not have enough energy. If you have too much energy containing foods you will become overweight. If you think that you are overweight you might try taking more exercise to "burn off" some of the excess food which you ate at you last meal.

Carbohydrates: these provide a source of energy.
Proteins: these provide a source of materials for growth and repair.
Fats: these provide a source of energy and contain fat soluble vitamins.
Vitamins: these are required in very small quantities to keep you healthy.
Mineral Salts: these are required for healthy teeth, bones, muscles etc..
Fibre: this is required to help your intestines function correctly; it is not digested.
Balanced Diets: we must have the above items in the correct proportions.

Carbohydrates

Carbohydrates are the most important source of energy. They contain the elements Carbon, Hydrogen and Oxygen. The first part of the name "carbo-" means that they contain Carbon. The second part of the name "-hydr-" means that they contain Hydrogen. The third part of the name "-ate-" means that they contain Oxygen. In all carbohydrates the ratio of Hydrogen atoms to Oxygen atoms is 2:1 just like water.

We obtain most of our carbohydrate in the form of starch. This is found in potato, rice, spaghetti, yams, bread and cereals. Our digestive system turns all this starch into another carbohydrate called glucose. Glucose is carried around the body in the blood and is used by our tissues as a source of energy. Any glucose in our food is absorbed without the need for digestion. We also get some of our carbohydrate in the form of sucrose; this is the sugar which we put in our tea and coffee (three heaped spoonfuls for me!). Both sucrose and glucose are sugars, but sucrose molecules are too big to get into the blood, so the digestive system turns it into glucose.

When we use glucose in tissue respiration we need Oxygen. This process produces Carbon Dioxide and water and releases energy for other processes. Now try my starch test in the Virtual Laboratory.

Proteins

Proteins are required for growth and repair. Proteins contain Carbon, Hydrogen, Oxygen, Nitrogen and sometimes Sulphur. Proteins are very large molecules, so they cannot get directly into our blood; they must be turned into amino-acids by the digestive system. There are over 20 different amino-acids. Our bodies can turn the amino-acids back into protein. When our cells do this they have to put the amino-acids together in the correct order. There are many millions of possible combinations or sequences of amino-acids; it is our DNA which contains the information about how to make proteins. Our cells get their amino-acids from the blood. Now try my Biuret test in the Virtual Laboratory.

Proteins can also be used as a source of energy. When excess amino-acids are removed from the body the Nitrogen is excreted as a chemical called urea. The liver makes urea and the kidney puts the urea into our urine.

Fats

Like carbohydrates, fats contain the elements Carbon, Hydrogen and Oxygen. Fats are used as a source of energy: they are also stored beneath the skin helping to insulate us against the cold. Do not think that by avoiding fat in your diet you will stay thin and elegant! If you eat too much carbohydrate and protein, you will convert some of it into fat, so you will put on weight. You must balance the amount of energy containing foods with the amount of energy that you use when you take exercise.

You must have some fat in your diet because it contains fat soluble vitamins.

Vitamins

Vitamins are only required in very small quantities. There is no chemical similarity between these chemicals; the similarity between them is entirely biological.

	Vitamin A: good for your eyes.
	Vitamin B: about 12 different chemicals.
	Vitamin C: needed for your body to repair itself.
	Vitamin D: can be made in your skin, needed for absorption of Calcium.
	Vitamin E: the nice one - reproduction?

Mineral Salts

These are also needed in small quantities, but we need more of these than we need of vitamins.

	Iron: required to make haemoglobin.
	Calcium: required for healthy teeth, bones and muscles.
	Sodium: all cells need this, especially nerve cells.
	Iodine: used to make a hormone called thyroxin.

Fibre

We do not // can not digest cellulose. This is a carbohydrate used by plants to make their cell walls. It is also called roughage. If you do not eat foods materials which contain fibre you might end up with problems of the colon and rectum. The muscles of you digestive system mix food with the digestive juices and push food along the intestines by peristalsis; if there is no fibre in your diet these movements cannot work properly.
