What is Nutrition and Why is it Important?

Nutrition is the science that interprets the nutrients and other substances in food concerning maintenance, growth, reproduction, health, and disease of an organism. It includes food intake, absorption, assimilation, biosynthesis, catabolism, and excretion. Nutrition is critical for our bodies to function correctly. It provides the necessary nutrients that our bodies need to create new cells, clean toxins, and to just perform everyday functions.

How Does Nutrition Impact Our Health?

Having a balanced diet rich in nutrients is crucial for good health. Poor nutrition can lead to a variety of health issues, including obesity, tooth decay, high blood pressure, and a weakened immune system. Conversely, good nutrition can help maintain a healthy weight, support your immune system, and reduce your risk of chronic diseases like heart disease and diabetes.

What are the Essential Nutrients Our Body Needs?

There are six essential nutrients that the body needs to function properly: carbohydrates, fats, proteins, vitamins, minerals, and water. Carbohydrates, fats, and proteins provide energy, while vitamins and minerals function in many metabolic reactions. Water plays a critical role in transporting nutrients and facilitating reactions in the body.

Are all Fats Bad for Our Health?

Contrary to popular belief, not all fats are bad for you. While saturated fats and trans fats can raise your cholesterol levels and increase your risk of heart disease, monounsaturated fats and polyunsaturated fats can lower these risks. Foods high in these healthy fats include avocados, nuts, seeds, and fish.

How Can We Ensure We are Getting a Balanced Diet?

Getting a balanced diet means eating a variety of foods from all food groups in the right proportions. Here are some tips:

• Eat at least five portions of a variety of fruit and vegetables every day.

• Base your meals on higher fibre starchy foods like potatoes, bread, rice or pasta.

• Include some dairy or dairy alternatives in your diet.

• Eat some beans, pulses, fish, eggs, meat and other proteins.
