As well as sharing tips and suggestions, I believe it is part of my responsibility as a trainer to provide education too. So today, I want to help you learn more about a topic that is VERY important for your overall health — nutrition. 


What is nutrition? 


The simple definition of nutrition is how food affects your body’s health. 

While nutrition can be a lot more complicated, with many different factors to consider, I think keeping the above definition in mind is important. 

A more complex definition of nutrition is that it is based on the biological processes of the body that convert food material into energy and/or living tissue. Or, to put it another way, how your body takes in food and absorbs the nutrients that are necessary for you to grow and be healthy. 

Nutrition is what helps your body to function, so it is a really important part of a healthy lifestyle!

Nutrition Definition


Why is good nutrition important?


To put it simply, without the proper nutrition, your body is unable to function at its best. 

Good nutrition allows you to fuel your body and nourish it for growth and repair — something that you need to do every day, especially if you are training regularly. 

When you’re eating a balanced range of vitamins and minerals, as well as getting plenty of energy from your food, this is good nutrition. Eating foods from all of the food groups is the best way to ensure a balanced, nutritionally rich diet. 

These food groups include:

  • Grains
  • Vegetables and legumes

  • Lean meat, seafood, eggs and meat alternatives

  • Dairy products and alternatives

  • Fruit, and

  • Healthy fats.
Importance Of Nutrition

Your nutritional requirements are unique to your body — especially if you have food sensitivities or intolerance’s to consider. 

Now that you know the answer when someone asks ‘what is nutrition’, I want to help you learn more about some key nutritional terms that I use throughout my blogs.


Nutrition Terms Explained


There are a few nutrition terms you may have come across on my blog, so I’ve included the definitions here to help you understand their meaning. 

1. Additives

As the name suggests, additives are added to food to improve the texture, color or flavor. They may also be used to preserve the food so that it lasts longer.

2. Bio-availability

This refers to how easily nutrients can be absorbed from your digestive tract into your bloodstream. 

Complete Proteins


3. Complete proteins

Complete proteins are protein-containing foods, such as eggs, soy and meat, that contain all the essential amino acids that your body requires. Your body isn’t able to produce these ‘essential’ amino acids on its own, so they must be absorbed from the food you eat and must be consumed regularly. 

4. Deficiency

To have a deficiency means you are lacking in something. So if you have a vitamin B deficiency, for example, you are not getting enough vitamin B to meet your body’s needs. 

5. Dehydration

When your body loses more water than it takes in, you can become dehydrated. Dehydration can be due to not drinking enough water, due to vomiting or diarrhoea or because of water lost through excessive sweating. 

6. Energy intake

Your body needs energy to perform even the most basic of functions, from sleeping to maintaining your body temperature. Your energy intake comes from the food and drink you eat. The amount of energy needed by your body depends on your age, height, weight and activity level. 

7. Fructose

Fructose is a form of natural sugar found in fruit and in honey. 

8. Gastrointestinal tract

Your gastrointestinal (GI) tract is an organ system that ingests and digests food, processes it and absorbs the nutrients before expelling the waste. 

9. Intolerance

A food intolerance is a negative reaction (such as bloating or altered bowel motions) to a food. Unlike a food allergy, a food intolerance does not involve an immune system response. 

10. Legume

Legumes refer to beans and peas from the Fabaceae family. This includes chickpeas, butter beans, adzuki beans, lentils, peas, cannellini beans, red kidney beans and lupins. 

11. Macronutrients

Macronutrients are key dietary nutrients — carbohydrates, protein and fat — that provide the body with energy. Macronutrients are required in large amounts, while micronutrients are needed in smaller amounts. 

12. Malnutrition

Malnutrition refers to a set of health problems that may be caused by a diet containing too much, or not enough, of a particular nutrient. This may be a result of a poor diet or a medical issue that affects nutrient absorption. 

13. Minerals

Minerals such as calcium, iron and potassium are naturally found in soil and water and are absorbed through these by plants. Your body obtains minerals from both plants and animals (who also get their minerals from plants). 

14. Nutrients

Generally classified into two categories, macronutrients and micronutrients, nutrients are the substances in your body that allow it to function. 

15. Organic

The organic definition can vary depending on the region but organic foods generally include those grown without pesticides or chemical fertilisers, without genetically modified (GM) components and with minimal environmental impact. 

Processed Foods


16. Processed foods

I’m sure this definition will raise a few eyebrows — processed foods refer to any foods that have undergone a ‘process’, even foods that have to be cooked before eating. 

Of course, there are different types of processed foods. Some are processed in order to help our bodies absorb the nutrients, while others are processed to include added sugars, salt or fats. Rather than avoiding all processed foods, reach for whole grains, fruits and vegetables that still contain lots of goodness. 

17. Refined

When a food is refined, such as sugar or white breads and pasta, it has had the outer layers removed or it has been through a form of processing. The process of refining can remove some of the food’s nutritional benefits.

18. Satiety / satiating

Satiety refers to how ‘full’ you feel after eating. A dish is satiating if it makes you feel as though you’ve eaten enough.  



19. Superfood

Any food that is nutrient-dense, providing a high concentration of vitamins and minerals in a small amount. Some examples of superfoods are chia seeds, turmeric and quinoa. 

20. Vitamins

Vitamins are organically made by plants and animals. They are then absorbed into your body when you eat vitamin-rich foods

21. Wholegrain

A grain food that has retained all parts — the germ, endosperm and bran layers — is known as a wholegrain.
