What You'll Learn
Five food groups
A balanced diet is one that fulfils all of a person's nutritional needs. It comprises foods from five groups: fruits, vegetables, protein, grains, and dairy.
Firstly, a balanced diet should include plenty of fruits and vegetables. Nutrition experts recommend eating whole fruits over fruit juice, as the latter contains fewer nutrients and often includes added sugar. People should opt for fresh, frozen, or fruits canned in water. When it comes to vegetables, it is important to eat a variety, including dark-green vegetables, red and orange vegetables, starchy vegetables, and beans, peas, and lentils.
Secondly, the grains group includes whole grains and refined grains. Whole grains include all three parts of the grain—the bran, germ, and endosperm—and are therefore broken down more slowly by the body, reducing their effect on blood sugar. They also tend to contain more fibre and protein. Examples of whole grains include brown rice, wholewheat pasta, and wholemeal bread.
Thirdly, the protein group includes beans, peas, and lentils, as well as other sources such as meat, fish, eggs, and dairy products. Dairy and fortified soy products are a vital source of calcium. People who are lactose intolerant can opt for low-lactose or lactose-free products or soy-based alternatives.
Fourthly, the dairy group includes milk, yoghurt, cheese, and their alternatives. These foods are a good source of calcium and protein.
Lastly, while oils are not a food group, they are emphasised as part of a healthy eating pattern because they are a major source of essential fatty acids and vitamin E. It is recommended to get most of your fat from unsaturated oils and spreads, as they can help lower cholesterol.
It is important to eat a variety of foods within each food group, as different foods provide varying amounts of key nutrients. Eating a balanced diet helps manage weight and reduces the risk of disease, giving the body the nutrients it needs to function effectively.

Nutritional needs
A balanced diet contains foods from the following groups: fruits, vegetables, protein, grains, and dairy. A healthy diet combines all the nutrients and food groups, in the right ratios.
Fruits and vegetables should make up half of a person's plate. It is recommended to eat whole fruits instead of getting them from juice, as juice contains fewer nutrients and added sugar. Vegetables should come from different subgroups to enjoy the most benefits. Starchy foods like potatoes, bread, rice, and pasta should make up just over a third of everything you eat. At least half of the grains consumed daily should be whole grains, which are a good source of fibre and usually contain more vitamins and minerals than refined grains.
The remaining half of the plate should consist of grains and protein. Dairy and fortified soy products are a vital source of calcium. People who are lactose intolerant can opt for low-lactose or lactose-free products or choose soy-based sources of calcium and other nutrients.
Healthy fats are essential for a healthy diet. Unsaturated fats like olive oil, sunflower oil, and safflower oil are considered healthy and can help lower cholesterol. Foods rich in healthy fats include chia seeds, ground flax, avocado, nuts, seeds, and fish.
It is important to note that nutritional needs may vary based on age, gender, body size, and level of activity. Combining a balanced diet with regular moderate exercise is essential for maintaining good health.

A balanced diet includes foods from five groups: fruits, vegetables, protein, grains, and dairy. It is recommended that half of your plate should consist of fruits and vegetables, while the other half should be made up of grains and protein. It is also important to accompany each meal with a serving of low-fat dairy or another source of dairy nutrients.
When it comes to fruits, it is recommended to eat whole fruits instead of getting them from juice. This is because juice contains fewer nutrients and added sugar, which can cause blood sugar spikes. It is also recommended to eat a variety of fruits and vegetables to get the most nutrients.
For grains, it is suggested that at least half of the grains consumed daily should be whole grains. Whole grains include all three parts of the grain—the bran, germ, and endosperm. They are broken down slowly by the body, which means they have a lesser effect on blood sugar levels. They also tend to contain more fiber and protein than refined grains.
Protein is an essential part of a balanced diet, making up a quarter of your plate. Healthy protein sources include fish, poultry, beans, nuts, eggs, and seeds. It is recommended to limit red meat and avoid processed meats.
Dairy is also an important source of essential nutrients like calcium, which helps keep bones strong and healthy. It is recommended to aim for 3 cups of dairy per day, choosing low-fat or fat-free products whenever possible. For those who are lactose intolerant, there are lactose-free options or soy-based sources of calcium and other nutrients.
In addition to these food groups, it is important to include healthy fats in your diet. This includes unsaturated oils like olive oil, sunflower oil, and safflower oil. Foods rich in healthy fats include chia seeds, avocado, nuts, and fish.
By eating a balanced diet, you can improve your health and reduce your risk of developing chronic health conditions and diseases. It is also important to combine a balanced diet with regular exercise to optimize your health and well-being.

Fats
A balanced diet is one that fulfils all of a person's nutritional needs. It comprises foods from five groups: fruits, vegetables, protein, grains, and dairy.
Fat is an essential part of a healthy, balanced diet. It is a source of essential fatty acids, which the body cannot produce itself. Fat helps the body absorb fat-soluble vitamins like vitamin A, vitamin D, and vitamin E. It also provides energy, protects organs, supports cell growth, and keeps cholesterol and blood pressure in check.
There are two main types of dietary fats: saturated and unsaturated. A third type, trans fats, has been largely eliminated from U.S. foods.
Saturated Fats
Saturated fats are the so-called "bad" fats. They are primarily found in animal products like beef, pork, and high-fat dairy foods such as butter, margarine, cream, and cheese. They are also present in some plant foods, like palm oil and coconut oil. Consuming too much saturated fat increases "bad" LDL cholesterol in the blood, which can form plaque in the arteries and raise your risk of heart disease and stroke. It is recommended that saturated fats make up 10% or less of your calorie intake.
Unsaturated Fats
Unsaturated fats are the "good" fats. They help to raise "good" HDL cholesterol levels, which picks up excess "bad" LDL cholesterol in the blood and moves it to the liver for disposal. Unsaturated fats can be further divided into monounsaturated and polyunsaturated fats. Monounsaturated fats are found in avocados, nuts, seeds, and plant oils, and they help protect your heart by maintaining levels of HDL cholesterol while reducing levels of LDL cholesterol. Polyunsaturated fats include omega-3 and omega-6 fatty acids, which are found in plant-based oils like soybean, corn, and safflower oils, as well as walnuts, flaxseeds, sunflower seeds, and fatty fish like salmon, mackerel, and tuna.
Tips for Including Healthy Fats in Your Diet
- Choose unsaturated oils and spreads, and consume them in small amounts.
- Opt for olive oil, especially extra virgin olive oil, which is the least processed type.
- Include more avocados, nuts, seeds, and fatty fish in your meals.
- Limit your consumption of deep-fried foods, as they are often high in calories and low in nutritional value.

Calories
A balanced diet provides the optimal number of calories for your body's needs. It's important to avoid "empty calories" from foods that are high in calories but offer little nutritional value, such as deep-fried foods and sugary drinks. Instead, focus on nutrient-dense foods that provide a good balance of essential nutrients and calories.
To manage your calorie intake, consider the following strategies:
- Start your meals with a broth-based soup or a large salad. These foods are filling due to their fibre and water content, helping you feel satisfied with fewer calories.
- Increase the bulk of your meals with water or air. For example, broth-based soups, stews, hot cereals, and cooked grains can be bulked up, providing more volume and satisfaction.
- Opt for high-fibre foods. Fibre helps satisfy hunger and reduce appetite. Include plenty of fruits, vegetables, legumes, popcorn, and whole grains in your diet.
- Choose whole fruits over fruit juice. Juice often contains added sugar and fewer nutrients, resulting in empty calories. Fresh, frozen, or canned fruits in water are preferable.
- Limit your intake of salt, added sugars, and alcoholic beverages. These can contribute to health issues such as high blood pressure, tooth decay, obesity, and increased risk of certain cancers.
- Be mindful of portion sizes and the number of courses you consume. Buffets, for instance, tend to encourage overeating.
By focusing on nutrient-dense foods, avoiding empty calories, and incorporating strategies to manage your calorie intake, you can ensure your body receives the optimal number of calories it needs to function effectively.
