Eating a healthy, balanced diet is important for numerous reasons. Nutrition can influence and prevent many diseases and conditions, and it can also aid in weight management and general wellness. A healthy diet typically includes a variety of colours and types of foods, an adequate amount of energy to maintain a healthy body composition, and the right combinations of food groups. While the exact make-up of a healthy diet may vary depending on individual characteristics and cultural contexts, some general guidelines for a nutritious diet include consuming whole grains, limiting sugar and sodium intake, eating fruits and vegetables, and including good sources of protein.

What You'll Learn
Eat fruits and vegetables
Eating fruits and vegetables is an essential part of a healthy diet. They are packed with vitamins, minerals, and antioxidants, which may lower the risk of many diseases. Fruits and vegetables are low in fat, salt, and sugar, and they are a good source of dietary fibre, which can help prevent overconsumption of food by making you feel fuller for longer.
Fruits and vegetables contain many essential nutrients that many people do not get enough of. For example, potassium, dietary fibre, folate, vitamin A, and vitamin C are all found in fruits and vegetables. Eating a diet rich in these foods may reduce the risk of heart disease, including heart attack and stroke, and protect against certain types of cancers. Research has shown that consuming these nutrients as food is more beneficial for health than taking supplements.
The World Health Organization (WHO) recommends that adults eat at least 400 grams, or five portions, of fruit and vegetables per day to reduce the risk of disease and ensure adequate fibre intake. This amount can also help reduce total sugar intake. To get the most nutrients, it is important to eat a variety of fruits and vegetables of different types and colours. For example, try to include dark green leafy vegetables, yellow or orange fruits and vegetables, red fruits and vegetables, legumes (beans), peas, and citrus fruits in your diet.
Fruits and vegetables can be eaten in various forms, such as raw, cooked, frozen, or canned, and they can be incorporated into meals in many ways, such as sauces, minced meals, or curries. They can also be eaten as snacks instead of sugary alternatives. When buying fruits and vegetables, it is best to choose those that are in season, as they will be more nutritious and budget-friendly. However, frozen or canned vegetables are also good options, as they are just as nutritious and can be more affordable.

Limit fats, salt and sugar
To lead a healthy life, it is important to limit the consumption of fats, salt, and sugar. This can be done by making a few changes to one's diet and cooking methods.
Firstly, it is important to limit the consumption of foods and drinks that contain high amounts of sugars. This includes sugar-sweetened beverages, sugary snacks, and candies. Instead, opt for fresh fruits and raw vegetables as snacks. Adults and children should reduce their intake of free sugars to less than 10% of their total energy intake. A further reduction to less than 5% of total energy intake can provide additional health benefits. Consuming free sugars increases the risk of dental caries (tooth decay) and can also lead to unhealthy weight gain, which can result in obesity.
When it comes to fats, it is recommended to reduce the total fat intake to less than 30% of total energy intake to prevent unhealthy weight gain. This includes limiting saturated fats to less than 10% of total energy intake and reducing trans fats to less than 1%. It is also important to eliminate industrially-produced trans fats, which are often found in partially hydrogenated vegetable oils used in processed foods.
Salt consumption should also be limited to less than 5 grams per day. Most people consume too much sodium through salt, which contributes to high blood pressure and increases the risk of heart disease and stroke. Salt is often found in processed foods, such as ready meals, processed meats, cheese, and salty snacks. It is also added during cooking or at the table. To reduce salt intake, opt for fresh, frozen, or no-salt-added canned vegetables and choose fresh, unprocessed meats. Flavor foods with herbs and spices instead of salt.
By making these changes and adopting healthier cooking methods, such as boiling, steaming, or baking instead of frying, individuals can improve their health and reduce the risk of chronic diseases.

Consume whole grains
Consuming whole grains is an important part of a healthy diet. Whole grains are a good source of dietary fibre, which has numerous health benefits. Firstly, dietary fibre can help to lower cholesterol levels, which in turn reduces the risk of developing heart disease. Eating fibre-rich foods can also help to prevent obesity and maintain a healthy weight, as they increase satiety and can reduce the overall number of calories consumed. In addition, dietary fibre has been linked to a reduced risk of developing certain types of cancer, as well as other serious diseases.
Whole grains are a diverse group of foods that includes unprocessed maize, millet, oats, wheat, and brown rice. These foods are considered healthier alternatives to refined grains, such as those found in white bread and pasta. When grains are refined, they undergo processing that removes parts of the grain, including the fibre-rich outer layer, or bran. This process often adds calories and sugar while removing essential nutrients. As such, it is recommended to choose whole grains over refined grains wherever possible.
There are many simple ways to incorporate more whole grains into your diet. For example, choosing wholemeal or multigrain bread instead of white bread, and brown rice instead of white rice. Other whole grain options include quinoa, barley, rye, and buckwheat, which can be used as alternatives to more refined grain products such as white flour. Porridge made from whole grains such as oats or barley is a healthy breakfast option, and whole grain cereals are also widely available.
It is important to note that not all whole grains are equally nutritious. Some products may be labelled as "made with whole grains" but still contain large amounts of sugar, salt, or other unhealthy additives. It is always important to read nutrition labels and compare products to make the healthiest choice. In addition, those with certain digestive conditions may find that some whole grains trigger symptoms, and should seek advice from a healthcare professional to determine which whole grains are suitable for their diet.

Drink milk and eat dairy
Drinking milk and consuming dairy products is an important part of a balanced diet for many people, especially children. Milk is a good source of calcium, protein, and vitamins B12 and D, which are critical nutrients for adults and children. Vitamin D, in particular, helps the body maintain proper levels of calcium and phosphorus, which are essential for building and maintaining bones.
Milk and dairy products are also a good source of potassium, which is often lacking in many diets, and may help maintain healthy blood pressure. In addition, milk is a good source of protein, which may protect against bone loss, especially in women who do not consume enough calcium. Studies suggest that consuming milk and dairy products may prevent osteoporosis and reduce the risk of fractures.
For those who are unable or choose not to consume dairy, there are a variety of non-dairy milk alternatives available, including almond, soy, coconut, cashew, hemp, and oat milk. These alternatives may have calcium added to them, but the amount of calcium that can be absorbed by the body varies.
In addition to milk, other dairy products such as yogurt and cheese can be incorporated into the diet to get similar nutrient profiles. For example, yogurt contains the same amount of protein, calcium, and phosphorus as milk and can be a healthy and versatile alternative to processed dips and toppings.

Eat beans, pulses, fish, meat and eggs
Eating beans, pulses, fish, meat, and eggs can be a healthy way to get a range of important nutrients. These foods are good sources of protein, vitamins, and minerals, including iron, zinc, and B vitamins. They can also be a source of healthy fats, like omega-3 fatty acids, which are essential for keeping our hearts healthy.
When it comes to meat, it's important to make healthy choices. Red meat, including beef, lamb, and pork, can be included in a healthy diet, but it's best to choose leaner cuts like chuck, bottom round, or pork loin to reduce fat intake. It's also a good idea to trim any visible fat from the meat and go for skinless chicken to further reduce fat content. Processed meats, such as bacon, ham, sausages, and salami, are generally high in fat, salt, and sodium, so these should be consumed in moderation or replaced with plant-based sources of protein.
Beans and pulses are excellent, inexpensive alternatives to meat. They are good sources of protein, fibre, vitamins, and minerals, and they help to make meals more filling. Examples include lentils, chickpeas, and beans, which can be easily incorporated into dishes like stews and casseroles.
Fish is another important part of a healthy diet. White fish, such as haddock, cod, and hake, is low in fat and a great source of vitamins and minerals. Oily fish like salmon and mackerel are rich in omega-3 fatty acids and vitamins A and D, but it's important not to overconsume them due to potential pollutant build-up. Aim for two portions of fish per week, one of which is oily.
Eggs are a nutritious choice, providing protein, vitamins, and minerals, especially iron. They are considered a meat serving, and while they do contain cholesterol, this has little effect on the body's cholesterol levels for healthy adults. It's recommended to consume up to seven eggs per week, and they can be used in a variety of quick, healthy dishes.
