​Essential Nutrients for life

1

​Macros


The ​four macronutrients all have their own specific roles and functions in the body and supply us with calories or energy. For this reason, the body requires these nutrients in relatively large amounts to grow, develop, repair and feel good!

Each macronutrient is almost always found in every item of food, whether that’s a healthy snack bar, or a raw vegetable; the only difference is how the macronutrients are balanced. As an example, the nutritional composition of an avocado is generally made up of 75% (good) fats, 20% carbohydrates and 5% protein, therefore this is clearly a fat-based food. On the other hand a banana consists of 95% carbohydrates, with only small amounts of protein and fats. 

The trick is to understand how each macronutrient plays a different role in the body and tailor your diet accordingly!

​Micros

​Micronutrients are not needed in the same quantities as macros, however are still equally as important. Micronutrients work in tandem with macronutrients to keep the body functioning and are crucial in order to maintain energy levels, metabolism, cellular function, and physical and mental wellbeing.

​Water

You can go for weeks without food, but you can’t last more than a few days without water. Water is absolutely crucial for every system in your body. It’s also the main thing you are made of. About 62 percent of your body weight is water. It improves your brain function and mood. It acts as a shock absorber and a lubricant in the body. It also helps flush out toxins, carry nutrients to cells, hydrate the body, and prevent constipation.
