The Basics of Nutrition
What is nutrition?
Nutrition is the science of how food and drink affect our bodies. It involves the intake, digestion, absorption, transport, metabolism, and excretion of nutrients. Nutrients are substances that provide our bodies with the energy and building blocks it needs to function properly.
What are the different types of nutrients?
There are six essential nutrients that our bodies need to function properly:
- Carbohydrates are the body’s main source of energy. They are found in foods such as bread, pasta, rice, fruits, and vegetables.
- Proteins are used to build and repair tissues. They are found in foods such as meat, poultry, fish, beans, and nuts.
- Fats are used for energy storage and to help the body absorb vitamins. They are found in foods such as butter, oil, nuts, and seeds.
- Vitamins are essential for a variety of bodily functions, such as growth, development, and metabolism. They are found in foods such as fruits, vegetables, and whole grains.
- Minerals are also essential for a variety of bodily functions, such as bone health, muscle function, and nerve function. They are found in foods such as dairy products, leafy green vegetables, and nuts.
- Water is essential for life. It helps to regulate body temperature, lubricate joints, and transport nutrients throughout the body.
Why is it important to eat a balanced diet?
A balanced diet is one that provides your body with all of the nutrients it needs in the right amounts. Eating a balanced diet is important for maintaining a healthy weight, reducing your risk of chronic diseases, and improving your overall health and well-being.

Tips for Making Healthy Eating Choices
Making healthy eating choices can be challenging, but it’s important to remember that small changes can make a big difference. Here are a few tips to help you get started:
- Make half of your plate fruits and vegetables. Fruits and vegetables are packed with nutrients and fiber, and they are low in calories. Eating more fruits and vegetables can help you to maintain a healthy weight, reduce your risk of chronic diseases, and improve your overall health and well-being.
- Choose whole grains over refined grains. Whole grains are a good source of fiber, which can help you to feel full and satisfied after eating. They are also a good source of vitamins, minerals, and antioxidants.
- Limit unhealthy fats. Unhealthy fats, such as saturated and trans fats, can increase your risk of heart disease and other chronic diseases. Choose lean protein sources, such as fish, chicken, and beans, and limit your intake of red meat and processed meats.
- Choose low-sugar drinks. Sugar-sweetened drinks are a major source of added sugar, which can contribute to weight gain, tooth decay, and other health problems. Choose water, sparkling water, or unsweetened tea or coffee instead.
- Make small changes to your diet gradually. Trying to change your diet too quickly can be overwhelming and can lead to burnout. Start by making small changes, such as adding a serving of fruit to your breakfast or lunch, or swapping out a sugary drink for water.
