Eating a balanced diet is an essential part of maintaining good health and can help you feel your best. A balanced diet provides the body with the right mix of nutrients and calories to function effectively and stay healthy. It includes foods from five groups: fruits, vegetables, protein, grains, and dairy. The specific dietary needs of an individual may vary depending on their age, sex, and physical activity level. For instance, males tend to need more calories than females, and people who exercise require more calories than those who don't. A balanced diet helps manage weight and lowers the risk of diseases such as heart disease, type 2 diabetes, cancer, and stroke.

What You'll Learn
Nutrients, minerals and vitamins
Nutrients, minerals, and vitamins are essential for the body to function correctly and stay healthy. A balanced diet provides the body with these essential components and helps manage weight and reduce the risk of diseases.
A healthy, balanced diet includes a variety of fruits and vegetables, protein, grains, and dairy. Fruits and vegetables should make up half of the plate, with a focus on whole fruits over fruit juices, as the latter contains fewer nutrients and added sugar. Vegetables from all five subgroups should be consumed weekly, including colourful veggies and crunchy seeds.
Protein-rich foods such as meat, eggs, fish, beans, nuts, and legumes are essential. For those following a vegan diet, plant-based sources of protein like tofu and beans can be included. Dairy products provide essential nutrients like calcium for strong teeth and bones, and low-fat or fat-free options are recommended.
Grains, preferably whole grains, should make up about a quarter of the plate. Whole grains include the bran, germ, and endosperm, providing more fibre and protein than refined grains. Healthy unsaturated oils, such as olive oil, sunflower oil, and safflower oil, are recommended in limited quantities.
Additionally, pulses, including beans, peas, and lentils, are excellent sources of fibre, protein, vitamins, and minerals. Nuts are also high in fibre but should be consumed in moderation due to their high-fat content. Oily fish, such as salmon, is rich in omega-3 fatty acids and should be consumed at least once a week.
By including a variety of foods from these groups and maintaining a balanced plate, individuals can ensure they are meeting their nutritional needs and optimising their health.

Calories and energy
Calories are a measure of the energy that foods supply. The number of calories you need depends on your sex, age, and activity level. The average person needs about 2,000 calories every day to maintain their weight, but this can vary from 1,600 to 3,000 calories per day depending on individual factors. Men tend to need more calories than women, and people who exercise require more calories than those who don't.
A balanced diet provides the optimal number of calories for your body's needs. It helps you maintain a healthy weight and reduces the risk of chronic diseases. Eating a balanced diet means consuming a variety of foods from different groups, including fruits, vegetables, protein, grains, and dairy.
Fruits and vegetables should make up about half of your plate. Choose a variety of colourful fruits and vegetables to get the most nutrients. Fruits can be fresh, frozen, or canned in water instead of syrup. It is best to avoid fruit juice as it is high in sugar and provides fewer nutrients.
Protein foods, such as meat, eggs, fish, beans, nuts, and legumes, should make up about a quarter of your plate. It is important to include lean protein sources and plant-based proteins for a balanced diet.
Grains, preferably whole grains, should also make up about a quarter of your plate. Whole grains are more nutritious than refined grains and have a smaller impact on blood sugar levels.
Dairy products provide essential nutrients like calcium. Aim for low-fat or fat-free dairy and limit consumption to one to two servings per day. If you do not consume dairy, there are nutrient-rich alternatives available.
In addition to these food groups, it is important to choose healthy fats and avoid trans fats. Olive oil, especially extra virgin olive oil, is considered a healthy fat. Nuts, seeds, and fatty fish are also good sources of healthy fats. However, it is important to consume these foods in moderation as they are high in energy.
Deep-fried foods and sugary drinks should be limited as they are high in calories and low in nutritional value. Alcoholic beverages can also affect cholesterol and insulin levels and contribute to weight gain, so they should be consumed in moderation.

Food groups
A balanced diet is one that provides the body with the nutrients it needs to function effectively and stay healthy. It consists of foods from five groups: fruits, vegetables, protein, grains, and dairy.
Fruits
Fruits are an essential component of a balanced diet, providing the body with vitamins, minerals, and fibre. It is recommended to consume at least two cups of fruit per day, including a variety of fresh, frozen, or dried fruits. However, it is important to be mindful of the natural sugars present in dried fruits. While fruit juices can be a source of nutrients, they tend to have high sugar levels and should be consumed in moderation.
Vegetables
Vegetables are a key part of a balanced diet, offering an array of vitamins, minerals, and fibre. Aim to include a variety of colourful vegetables in your meals, as different colours indicate different types of nutrients. Vegetables should make up about a quarter to half of your plate, depending on whether you are also consuming fruits.
Protein
Protein-rich foods are necessary for a balanced diet as they provide the body with essential amino acids, which are the building blocks of muscles, skin, and other tissues. Good sources of protein include lean red meats, seafood, poultry, eggs, beans, nuts, and seeds. When consuming meat, it is advisable to choose lean cuts and limit processed meat products.
Grains
Grains, especially whole grains, are an important source of carbohydrates, fibre, and protein in a balanced diet. Examples of whole grains include brown rice, whole wheat flour, and oatmeal. It is recommended that grains occupy about a quarter of your plate, amounting to approximately six ounces per day.
Dairy
Dairy products are a good source of calcium, which is crucial for maintaining strong bones and teeth. Low-fat or fat-free dairy options such as milk, yoghurt, and cheese can provide the necessary calcium while minimising saturated fat intake. It is generally recommended to limit dairy consumption to one to two servings per day.

Weight management
To manage weight effectively, it is important to consume foods from all the major food groups, including fruits, vegetables, protein, grains, and dairy. The USDA's "ChooseMyPlate" initiative recommends filling half of your plate with fruits and vegetables, a quarter with protein, and the remaining quarter with whole grains and starches. This ensures a balanced intake of nutrients and promotes a healthy weight.
In addition to a balanced diet, regular exercise is crucial for weight management. Engaging in physical activities such as walking, cardio, and resistance training can help burn calories and speed up weight loss. For those looking to lose weight, combining a balanced diet with an exercise routine can be highly effective. The NHS offers a free 12-week weight loss plan that combines diet and exercise to promote safe and sustainable weight loss.
When it comes to specific foods for weight management, it is important to choose natural, unprocessed foods over prepackaged meals and snacks. Whole grains, such as brown rice and whole wheat bread, are recommended as they provide more fiber and protein than refined grains and have a slower impact on blood sugar levels. Healthy fats, such as olive oil, nuts, and avocados, are also beneficial, but portion sizes should be considered as they are calorie-dense.
Soups can also be a helpful tool for weight management. A vegetable-based clear soup before a meal can help you feel fuller and eat less overall. Additionally, broth-based or tomato-based soups are better for weight management than creamy or cheesy soups. While it is important to focus on nutritious foods, it is also crucial to be mindful of portion sizes, especially when it comes to high-fat foods.
