A balanced diet is essential for maintaining good health and ensuring your body gets the nutrients it needs to function effectively. Nutrients are compounds that the body cannot produce on its own or in sufficient quantities. There are six essential nutrients that our bodies require: protein, carbohydrates, fats, vitamins, minerals, and water. These nutrients provide the body with energy and support various bodily functions. A healthy diet includes a variety of nutrient-dense foods from different food groups, including fruits and vegetables, grains, dairy or dairy alternatives, and protein sources such as meat, eggs, fish, beans, and nuts. While individual dietary needs may vary, a balanced diet generally involves consuming the right amount of calories and nutrients while limiting the intake of unhealthy fats, added sugars, and processed foods.
| Characteristics | Values |
|---|---|
| Calories | Calories are a measure of energy that foods supply. The number of calories you need will depend on your sex, age, and activity level. |
| Macronutrients | Macronutrients are the primary building blocks of your diet and provide your body with energy. They are needed in large amounts and include protein, carbohydrates, and fats. |
| Protein | Protein should make up 10% to 30% of your daily calories. Good sources of protein include meat, eggs, fish, beans, nuts, and legumes. |
| Carbohydrates | Carbohydrates can be simple or complex. Simple carbs are digested quickly and cause rapid blood sugar spikes, while complex carbs take longer to digest and don't cause as big of a blood sugar spike. |
| Fats | Some fat is essential for energy and cell health, but too much can increase calories and lead to weight gain. Choose unsaturated fats over saturated fats to lower cholesterol and reduce the risk of heart disease. |
| Vitamins and Minerals | Vitamins and minerals are essential for maintaining bodily functions and promoting overall well-being. Good sources include dairy, meat, eggs, fish, and nuts. |
| Water | Water is crucial for every system in your body. Drinking enough water can help prevent dehydration and its associated symptoms, such as constipation, headaches, and fatigue. |
| Fibre | Fibre is a type of carbohydrate found in fruits, vegetables, legumes, and whole grains. It helps to ensure adequate daily intake and promotes healthy digestion. |

Carbohydrates: Focus on complex carbs like vegetables, fruits, whole grains, and beans
Carbohydrates are an important nutrient found in numerous types of food. They provide essential nutrients and are one of the main sources of calories for our bodies. They can be classified into simple and complex carbohydrates. Complex carbohydrates, such as fruits and vegetables, are loaded with healthy nutrients. They are digested more slowly and release glucose into the bloodstream more gradually. They are higher in fibre and digest more slowly, making them more filling and a good option for weight control.
Focus on eating complex carbohydrates like vegetables, fruits, whole grains, and beans. For instance, apples, berries, and bananas are good sources of fibre. Whole grains are also good sources of fibre, as well as potassium, magnesium, and selenium. Choose less processed whole grains such as quinoa, buckwheat, brown rice, and whole-wheat pasta. Avoid canned fruits and fruit juices since they usually contain added syrup. Instead, opt for fresh or frozen fruits or fruits canned in water.
When choosing grains, remember that refined grains, such as white flour and white rice, have been processed and stripped of beneficial nutrients and dietary fibre. In contrast, unrefined whole grains retain these vital nutrients and are rich in fibre, which supports digestive health and helps control cholesterol. Eating fibre helps you feel full, so you are less likely to overeat.
Legumes, beans, lentils, and dried peas are also excellent sources of complex carbohydrates. They are naturally very low in fat and high in fibre, protein, vitamins, and minerals.

Proteins: Include meat, eggs, fish, beans, nuts, and legumes
A balanced diet is one that provides all the nutrients your body needs to function properly and stay healthy. Nutrients are compounds that the body cannot produce on its own or in sufficient quantities. There are six essential nutrients: protein, carbohydrates, fats, vitamins, minerals, and water.
Protein is one of the six essential nutrients and is necessary for the body to grow and repair itself. According to the Dietary Guidelines for Americans, protein should make up 10% to 30% of your daily calories. The amount of protein you need depends on factors such as your age and activity level.
Protein-rich foods include meat, eggs, fish, beans, nuts, and legumes. Meat is a good source of protein, vitamins, and minerals, including iron, zinc, and B vitamins. It is also one of the main sources of vitamin B12. When consuming meat, opt for lean cuts and skinless poultry to reduce fat intake. It is also recommended to limit the consumption of red and processed meat.
Eggs and fish are also excellent sources of protein and provide many vitamins and minerals. It is suggested to consume at least two portions of fish per week, including one portion of oily fish. Beans, peas, and lentils are good protein sources, especially for plant-based diets, and are naturally low in fat and high in fibre, vitamins, and minerals. Nuts are high in fibre and healthy fats, but due to their high-fat content, they should be consumed in moderation.

Fats: Consume unsaturated fats like olive oil, and limit saturated and trans fats
A balanced diet is essential for maintaining good health and ensuring the body receives the necessary nutrients to function effectively. While fat is an essential component of a healthy diet, it is crucial to focus on consuming primarily unsaturated fats, such as olive oil, while limiting saturated and trans fats.
Fats are a critical part of a balanced diet, providing essential fatty acids that the body cannot produce on its own. They also aid in the absorption of vital nutrients like vitamins A, D, and E. However, not all fats are equal, and it's important to prioritize unsaturated fats over saturated and trans fats. Unsaturated fats are predominantly found in oils from plants and fish, and they include monounsaturated and polyunsaturated fats. Monounsaturated fats, such as those found in olive oil, help maintain healthy levels of "good" HDL cholesterol while reducing "bad" LDL cholesterol. This beneficial effect on cholesterol levels contributes to a reduced risk of cardiovascular disease and promotes overall heart health.
Olive oil, especially extra virgin olive oil, is widely recognized as a healthy fat option. It is rich in monounsaturated fats, specifically oleic acid, which accounts for about 71% of its total fat content. Extra virgin olive oil also contains powerful antioxidant compounds like vitamin E, oleacein, and oleocanthal, which offer anti-inflammatory benefits. Regular consumption of olive oil has been linked to lower levels of inflammatory markers, such as CRP and interleukin-6, suggesting potential protection against chronic inflammatory diseases, including heart disease.
In addition to its heart-healthy properties, olive oil may offer other health advantages. Studies indicate that olive oil may play a role in weight management. For instance, a 2018 review found that diets high in olive oil facilitated greater weight loss compared to diets with lower olive oil content. Additionally, the Mediterranean diet, which features olive oil prominently, has been associated with positive effects on body weight. Olive oil may also provide benefits beyond weight management, as suggested by a 2019 study that found a reduced likelihood of developing diabetes among prediabetic individuals who consumed oleanolic acid-enriched olive oil.
While fats are an essential part of a balanced diet, it is important to limit the consumption of saturated and trans fats. Saturated fats, primarily derived from animal sources and some plant foods, can increase levels of "bad" LDL cholesterol in the blood, elevating the risk of heart disease and stroke. Trans fats, which are typically artificially created and found in processed foods, should be avoided altogether due to their negative impact on health. By reducing the intake of saturated and trans fats and incorporating more unsaturated fats, individuals can promote a healthier lipid profile and overall well-being.

Vitamins and minerals: Get these from dairy, meat, eggs, fish, and nuts
A balanced diet is essential to maintaining good health and ensuring that your body functions correctly. Vitamins and minerals are considered micronutrients and are required for our bodies to function properly. Since they are not made in the body, we need to obtain them from our diet.
Dairy products are an excellent source of vitamins and minerals, particularly calcium, which plays an important role in bone health. Milk, yoghurt, and cheese are recommended as part of a balanced diet, with reduced-fat options being preferable for adults. In addition to calcium, milk is also a good source of vitamin A, vitamin D, and vitamin C.
Meat is another rich source of vitamins and minerals, with some nutrients found only in meat or more bioavailable forms of certain nutrients. Red meat and organ meats, in particular, are exceptional sources of vitamin D3, vitamin A, and niacin. Meat also contains riboflavin, a pro-metabolic B vitamin that helps release energy from food and promotes healthy vision and iron uptake.
Eggs are a nutritionally dense food, providing essential lipids, proteins, vitamins, and minerals at a moderate calorie count. They are a good source of vitamin A, iron, vitamin B12, riboflavin, choline, zinc, and calcium.
Fish is an important source of vitamins and minerals, as well as lean animal protein and omega-3 fatty acids. It is particularly rich in vitamin A, vitamin B-complex, and vitamin D. Fish also provides minerals such as magnesium, calcium, selenium, zinc, iodine, and iron.
Nuts are known for their high protein and healthy fat content, but they also provide essential vitamins and minerals. Many nuts contain vitamin E, which protects the skin, and are a good source of B-complex vitamins. Chestnuts stand out for their high vitamin C content, while other nuts like macadamia nuts provide calcium, iron, magnesium, and selenium.
Incorporating these foods into your diet can help ensure you are getting a variety of vitamins and minerals to support your overall health and well-being.

Water: Stay hydrated by drinking enough water and eating water-rich foods
Water is essential for maintaining a balanced diet and staying hydrated. It is involved in many important functions in the body and makes up a majority of our body weight. The body requires water to maintain the health and integrity of its cells, regulate body temperature, aid digestion, and flush out waste. Water also helps to reduce the risk of urinary tract infections, lubricate and cushion joints, and carry nutrients and oxygen to cells.
Drinking plenty of water is crucial for staying hydrated, especially during physical activity or in warm conditions when the body loses fluids through sweating. The amount of water needed varies depending on activity levels, sex, weight, age, and medical conditions. The Dietary Reference Intake for water is between 91 and 125 fluid ounces (2.7 to 3.7 litres) per day for adults. However, it is important to listen to your body and drink water when you feel thirsty to ensure you stay hydrated.
Water is the best drink for hydration as it does not contain any additional calories or sugar. Other beverages, such as milk, coffee, tea, and juice, can also contribute to fluid intake, but they may contain added sugars or substances that affect hydration levels. It is recommended to choose water over sweetened drinks to avoid consuming excess calories and maintain optimal hydration.
Eating water-rich foods can also contribute to hydration. Certain fruits and vegetables have high water content, such as watermelon, strawberries, cucumbers, celery, and zucchini. Including these foods in your diet can help you stay hydrated and obtain essential nutrients.
In addition to hydration, water plays a crucial role in weight loss and maintaining a healthy weight. Adequate water intake helps the body eliminate waste and excess sodium, reducing fluid retention and promoting weight loss. Drinking water instead of sugary drinks can also reduce calorie intake and contribute to a calorie deficit, which is beneficial for weight management.
