The Balancing Act of a Healthy Diet

A healthy diet includes all the foods we eat and liquids we drink as well as the time between meals! Let’s say we eat all the right foods and then sit around all day without exercising. Let’s say that someone eats a diet high in sugar and fats and yet exercises regularly, who is to say who is the healthier of the two?

The truth is that a healthy balanced diet is really only this if we are getting a balanced diet of nutrients of ALL the foods we need to maintain our health as well as:

Getting regular exercise

Exercise helps the get the oxygen & blood moving faster around the body and increases the supply of oxygen to the cells. It increases the speed of the blood flow to and from vital organs and increases the amount of oxygen to the cells of these organs. Small amounts of regular exercise is a useful part of a healthy lifestyle.

Drink plenty of fresh water

Eating well should also include drinking well!
Our bodies are made up of approximately 70% water and drinking enough fresh water each day is so so important. Dramatic health improvements are made in many people once they start drinking enough water each day. So live well - eat well - drink well.

Nutrition Explained

Nutrition has a couple of meanings which are useful when looking at the subject. Nutrition can be defined as: The means by which living organisms take in food and use this food for energy and growth and to maintain health. The subject of nutrition is the science that deals with food and nourishment, especially in humans.

The word ‘Nutrition’ itself is taken from the Latin ‘nutricius’ meaning that which nourishes or suckles, taken from the Indo-European ‘Sans Snauti’ – literally ‘she gives milk’. Let’s have a look and see what food groups we can get the most nourishment from:

The Main Food Types

All that you have eaten and all that you will eat falls into one of 5 main food types. Whether your food comes from Yorkshire in England or New Delhi in India, it falls into one of the 5 main food types and here they are:

  • Carbohydrates which include cereals, bread, rice, grains.
  • Vitamins & minerals including fruit & vegetables
  • Proteins including fish, meat, cheese, tofu, soya products
  • Fats & oils including all the cooking oils, butter & cream, milk & dairy product
  • Fibre

What we eat affects our health and energy levels. If we only drank sugary drinks, processed foods and took little or no exercise, we would could not expect our body to respond with vigor and health. Carefully planned nutrition must provide an energy balance and a nutrient balance. To maintain health, it is advised that we eat foods from these main groups daily.

Carbohydrates

Carbohydrates or carbs as they are often called, are the most common source of energy found in foods. Carbohydrates are an essential component of living cells and an important source of energy for the body. One of the functions of the liver is to break down carbohydrates into blood sugar or glucose which is then used by the cells, tissues and organs for energy.

Some Food Sources of Carbohydrates

  • Rice
  • Wheat
  • Corn
  • Potatoes
  • Bread
  • Flours

Vitamins

Vitamins help the body to grow, helps to resist it to infections and helps to maintain the smooth and efficient running of the organs. We only require small doses of vitamins but as we cannot make them ourselves, we are dependent on the food we eat to ensure that we get the vitamins that we need.

A well balanced diet provides an adequate quantity of all vitamins and our supply comes mostly comes from the plant and animal foods we eat. Eating a balanced diet of a variety of fresh fruit & vegetables ensures we get the supply of vitamins that we need on a daily basis. Vitamins are either dissolvable in water or fat.

Examples of Vitamin Rich Foods

Milk is rich in Vitamin D which helps bones, teeth, nails & hair. Carrots are rich sources of Vitamin A and this helps to maintain healthy vision. Most fruits and green leafy vegetables have lots of Vitamin C which helps the body to stay healthy and heal itself it if gets sick or there is a cut.

Fresh foods are key. (However, frozen vegetables that are frozen whilst fresh can contain more vitamins and minerals than vegetables stored for a long time at room temperature. Freshly frozen foods and the technology of freezing has dramatically enhanced the availability of good foods around the planet.)

All cells in the body, no matter what their function, need protein to grow, to repair themselves, to fight off bacteria and to do their jobs.

What Proteins Do
