What You'll Learn
Nutrients: major and micro
Nutrients are essential compounds that our bodies need to function correctly and stay healthy. They provide energy and support growth and development. There are two main types of nutrients: major nutrients and micro-nutrients.
Major Nutrients
Major nutrients are required by the body in larger quantities. They include proteins, carbohydrates, and fats.
Proteins help build and repair muscles, tissues, and skin, as well as boost immunity and maintain fluid balance. Good sources of protein include tofu, beans, and dairy products.
Carbohydrates are the body's main source of energy. They should constitute a significant part of our diet, with a focus on complex carbohydrates like whole grains, fruits, and vegetables, which also provide essential fibre.
Fats are essential for maintaining body temperature and helping absorb fat-soluble vitamins like A, D, E, and K. It is important to choose healthy fats like unsaturated fats, found in olive oil, and avoid trans fats.
Micro-nutrients
Micro-nutrients, as the name suggests, are needed in smaller quantities. They include vitamins, minerals, and water.
Vitamins are organic compounds that support various bodily functions, including growth, cell function, and disease prevention. There are 13 essential vitamins, but some key ones to focus on are vitamins A, C, B, and D. These can be obtained from a variety of fruits and vegetables.
Minerals help release energy from food and promote the growth of organs. Some important minerals include calcium, iron, zinc, and potassium.
Water is essential for hydration and various bodily functions. It is recommended to consume at least eight glasses of water per day.
In summary, a balanced diet includes a variety of foods that provide the right types and amounts of these major and micro-nutrients. This balance ensures we get the energy and nutritional support we need to maintain health and prevent diseases.

Vitamins and minerals
Minerals are also essential in a balanced diet. They help release energy from food and promote the growth of organs. Some key minerals include iron, calcium, potassium, iodine, and sodium. Calcium, for example, is important for bone health, while iron helps to transport oxygen in the blood.
Fruits and vegetables are excellent sources of vitamins and minerals. Local and seasonal fruits tend to provide more nutrients than imported fruits. Nutrition experts recommend consuming whole fruits rather than fruit juice, as juice often contains fewer nutrients and added sugars. Similarly, cooking vegetables can reduce their nutritional value, so it is recommended to eat them raw or cooked using methods that do not add unhealthy fats.
In addition to natural food sources, some people may choose to take vitamin and mineral supplements to ensure they are meeting their nutritional requirements. However, it is important to remember that a balanced diet is generally preferable to relying on supplements, as it provides a wider range of nutrients and ensures the body can properly absorb and utilize them.
Overall, vitamins and minerals play a crucial role in maintaining health and preventing disease. By including a variety of vitamin- and mineral-rich foods in one's diet, individuals can help ensure they are meeting their nutritional needs and support their overall well-being.

Proteins and carbohydrates
A balanced diet is essential to maintaining health and well-being. It provides the body with the right types and amounts of nutrients to support normal growth and development, while preventing deficiencies and related diseases.
Proteins
Protein helps build and repair tissues, develop skin and hair, and support muscle growth and repair. It also boosts immunity, helps maintain fluid balance, and aids in healing. Protein-rich foods include meat, fish, eggs, dairy products, legumes, and nuts, and plant-based sources such as tofu and beans.
It is recommended that protein constitute around 10-12% of your diet, with some experts suggesting a range of 10-35% of your daily calorie intake. Eating protein early in the day can help manage cravings and support better sleep.
Carbohydrates
Carbohydrates are the body's preferred source of energy and its primary fuel. They are broken down into glucose, which is used as fuel by nearly every cell in the body, especially our brain, muscles, and organs. Carbohydrates are found in grains, fruits, vegetables, and legumes.
There are three types of carbohydrates: simple carbohydrates (sugars), complex carbohydrates (starches), and fibre. While simple carbs are digested and absorbed more quickly, complex carbs provide a more sustained source of energy and include fibre-rich, complex carbs like oats and starchy vegetables such as potatoes.
The recommended intake of carbohydrates is around 45-65% of your daily calorie intake. It's important to note that this may vary depending on individual factors such as age, sex, gender, and activity levels.
In summary, proteins and carbohydrates are essential components of a balanced diet. They each play unique and vital roles in supporting various bodily functions, providing energy, and promoting overall health and well-being.

Healthy fats
Fat is often associated with negative health consequences, but it is a necessary nutrient that should be included in a balanced diet. Consuming too much fat, especially saturated fats, can be harmful, but it is important to distinguish between saturated and unsaturated fats. A small amount of fat is an essential part of a healthy, balanced diet.
Types of Fats
There are four main types of dietary fats: saturated, trans, monounsaturated, and polyunsaturated. Saturated and trans fats are usually solid at room temperature, such as butter, while monounsaturated and polyunsaturated fats tend to be liquid, like canola oil. Saturated fats are found in both sweet and savoury foods, with most coming from animal sources, including meat and dairy products. They are also found in some plant foods, such as palm oil and coconut oil. Trans fats should be avoided as they can lead to heart disease and stroke.
Health Benefits of Healthy Fats
Incorporating Healthy Fats into Your Diet
To incorporate more healthy fats into your diet, choose liquid non-tropical plant oils, such as canola, soybean, corn, safflower, sunflower, and nut oils. Olive oil, especially extra virgin olive oil, is considered a healthy fat option. It is important to balance the consumption of healthy fats with physical activity to maintain a healthy weight and overall well-being.

Overall health and well-being
A balanced diet is key to maintaining overall health and well-being. It provides the body with the right types and amounts of foods and drinks to support normal growth and development, and to maintain health. A balanced diet includes major nutrients like proteins, carbohydrates, fats, vitamins, minerals, and water, as well as micronutrients such as calcium, magnesium, phosphorus, zinc, and selenium.
Proteins help build muscle and boost immunity, while carbohydrates provide energy. Fats are necessary for transporting vitamins and insulating organs, and they also help to maintain body temperature. Vitamins and minerals support various bodily functions, such as growth and organ development, and they protect against nutritional deficiencies. Water is essential for hydration and is used in many body functions.
Fruits and vegetables are an important part of a balanced diet, as they provide vitamins, minerals, and antioxidants. It is recommended that half of a person's plate should consist of fruits and vegetables. Whole fruits are a better source of nutrients than fruit juice, as juice often contains added sugar and has fewer nutrients. Local and seasonal fruits are fresher and provide more nutrients than imported fruits.
In addition to fruits and vegetables, a balanced diet includes lean protein, dairy, grains, and soluble fiber. It is important to eat a variety of foods from each food group to ensure adequate nutrient intake and prevent deficiencies that can impact health.
Maintaining a balanced diet, staying hydrated, and exercising regularly all contribute to overall well-being. A balanced diet can help prevent obesity, type 2 diabetes, cardiovascular disease, and some cancers. It can also help maintain a healthy weight, strengthen bones, support brain development, and boost immunity.
