Essential Nutrients You Need for Optimal Health

Achieving optimal health requires nourishing your body with the essential nutrients it needs. Essential nutrients are those that your body does not produce, so you must get them from your diet. Let’s take a look at the four key nutrients you must have in your diet to experience optimal health.


Protein is essential for growth and repair of the body. It helps form our muscles and organs, as well as skin, hair and nails. Proteins are made up of smaller molecules called amino acids, and some of these amino acids can only be obtained from the foods you eat.


Healthy fats, such as those found in avocado and nuts, are a key part of good nutrition. Fats are essential for energy, hormone production, absorption of nutrients, and tissue repair. They are also important for the maintenance of cell membranes.

Vitamins and Minerals:

Vitamins and minerals are essential for your cellular processes and metabolism. Vitamins and minerals help keep your bones and teeth healthy, your blood vessels functioning properly and your body’s cells functioning optimally.


Fibre is essential for your digestive health as it helps keep your blood sugar levels stable, and is important for cardiovascular health. A diet high in fibre has also been linked to positive effects on depression, and can help you to maintain a healthy weight.

In order to enjoy optimal health and nutrition, it is important to have the right balance of these essential nutrients in your diet. Here are some suggestions for ensuring you meet your nutritional needs:

  • Eat a variety of foods: Try to include a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats in your diet.
  • Choose whole grain options: Instead of choosing processed cereals and white bread, opt for whole grain alternatives. Whole grains contain the essential nutrients that you need.
  • Limit processed and fast foods: Eating processed and fast foods can deplete your body of essential nutrients. Aim to limit these foods and focus on nutrient-dense foods instead.
  • Include a rainbow of vegetables and fruits: Make sure to include a range of different coloured vegetables and fruits in your diet. Different colours indicate different vitamins and minerals, so the more variety you have, the more nutrients you get!

By including the essential nutrients in your diet, you can take your health to the next level. Give your body the nutrients it needs and it will reward you with a healthier and happier you!
