Eating a balanced diet is an essential part of maintaining good health and can help you feel your best. A balanced diet includes foods from five essential food groups: fruits, vegetables, protein, grains, and dairy. The right balance of nutrients and food groups is crucial, and it is recommended that half of your plate consists of fruits and vegetables, with the remaining half comprising grains and protein. Dairy or dairy alternatives can also be included to provide essential nutrients like calcium for strong bones and teeth. A balanced diet provides the body with the necessary nutrients, vitamins, minerals, and optimal calories for healthy functioning, reducing the risk of chronic diseases and helping to maintain a healthy body weight.

What You'll Learn
The importance of fruits and vegetables
Fruits and vegetables are essential components of a balanced diet, offering a multitude of health benefits. Firstly, they are rich sources of essential vitamins and minerals, including folate, potassium, fibre, magnesium, zinc, and vitamins C, E, A, and K. These nutrients are vital for maintaining good health and energy levels, and our bodies cannot produce them on their own.
Secondly, fruits and vegetables are excellent sources of dietary fibre, which aids in digestion, keeps digestion normal, and promotes a feeling of fullness, thereby reducing the risk of overeating and subsequent weight gain. Additionally, the fibre in these foods has been linked to lowering the risk of developing various diseases, including heart disease, type 2 diabetes, high blood pressure, and certain types of cancer.
Moreover, incorporating a variety of fruits and vegetables into your diet can help lower blood pressure and reduce the risk of cardiovascular disease. Research suggests that individuals who consume a higher amount of fruits and vegetables have a lower likelihood of experiencing a heart attack or stroke. Specifically, green leafy vegetables, such as spinach and kale, have been associated with decreased risks of cardiovascular disease.
Lastly, fruits and vegetables contribute to improved mental well-being. Studies have found a link between higher consumption of these foods and enhanced mental health, with frequent fruit intake associated with feelings of confidence, energy, and relaxation. Therefore, including a variety of colourful fruits and vegetables in your diet is not only beneficial for physical health but also for maintaining a healthy state of mind.

Lean protein sources
Meat and poultry are good sources of protein, but it is important to choose leaner options. Lean meats include chicken, turkey, beef, and pork. When choosing beef, opt for lean cuts with less than 10g of total fat and no more than 4.5g of saturated fat per 3.5 oz (100g) serving. Ground beef should be at least 90% lean. Similarly, for poultry, opt for skinless chicken breasts and turkey breasts. These white meats are the leanest cuts of the bird.
Fish is another excellent source of lean protein. White-fleshed fish, such as cod, haddock, grouper, halibut, tilapia, and bass, are quite lean and provide less than 3g of fat, 20-25g of protein, and 85-130 calories per 3.5 oz (100g). They are also good sources of hunger-satisfying protein with little fat and relatively few calories. However, it is beneficial to also include darker-fleshed fish like salmon, which is rich in omega-3 fatty acids that are beneficial for heart health. Aim to include at least two portions of fish in your weekly diet, with one of them being an oily fish like salmon.
For those who follow a vegetarian or vegan diet, there are plenty of plant-based protein sources available. Beans, peas, lentils, and pulses are excellent sources of lean protein and are also high in fibre. Tofu is another versatile option that provides adequate amounts of all the essential amino acids. Eggs are also a good source of protein for ovo-vegetarians.
Dairy products like milk, cheese, and yogurt are also rich in protein and other essential nutrients. However, they can be high in saturated fat, so it is recommended to choose low-fat or nonfat options and limit the consumption of cheese.

Dairy and alternatives
Dairy products are an important part of a balanced diet, providing protein, calcium, and a range of vitamins and minerals. Milk, yoghurt, and cheese are all good sources of these nutrients. However, they can also be high in saturated fat, so it's important to make healthy choices and opt for lower-fat options. For example, choose semi-skimmed, 1% fat, or skimmed milk, lower-fat hard cheeses, and lower-fat, lower-sugar yoghurt.
Dairy alternatives, such as soya, almond, rice, coconut, oat, hemp, and other plant-based "milks", can also be included in this food group. When choosing these alternatives, opt for unsweetened, calcium-fortified versions to ensure you're still getting the calcium your body needs. These alternatives are especially important for those who are intolerant of dairy, as they can still build a balanced diet by choosing a variety of nutrient-rich replacements.
For babies and young children, dairy is an essential part of their diet, providing the calcium and protein needed to build bones and keep teeth healthy. Breast milk is recommended for the first 6 months of a baby's life, and can be continued alongside solid foods for as long as desired. From 6 months onwards, babies can also eat pasteurised full-fat cheese, and foods containing full-fat dairy, such as cheese sauce and custard. From 1 year onwards, cows' milk can be given as a drink.
It's important to note that while dairy is a good source of calcium, it is not the only source. Dairy alternatives like fortified soy milk can also provide calcium, as well as potassium and vitamin D. Other sources of calcium include certain vegetables, such as broccoli and kale, although the amount of calcium that can be absorbed from these sources may vary.

Whole grains
When choosing grains, it is generally recommended to opt for whole grains over refined grains. Whole grains contain the entire grain, including the bran, germ and endosperm, whereas refined grains have been milled, removing the bran and germ. This refining process gives refined grains a finer texture and improves their shelf life, but it also strips them of important nutrients such as B vitamins, iron and dietary fibre. Examples of refined grains include white flour, white pasta and white rice. While some refined grains are enriched with added B vitamins and iron, they may still lack fibre.
To identify whole grain products, look for the words "whole" or "whole grain" listed first or second in the ingredient list. The American Heart Association (AHA) recommends choosing products that contain at least 51% whole grains versus refined grains. Additionally, aim to include a variety of whole grains in your weekly diet, such as whole wheat bread, brown rice, oats, quinoa, barley and corn.
It is worth noting that the body breaks down whole grains more slowly than refined grains, which means they have a lesser impact on blood sugar levels. This can be beneficial for maintaining stable blood sugar levels and reducing the risk of diabetes. Overall, including a good variety of whole grains in your diet can contribute to better health and help prevent various diseases.

Healthy fats
However, it is important to note that not all fats are healthy. Trans fats, for example, are harmful and should be avoided. They are known to increase "bad" LDL cholesterol levels in the blood, which can lead to cardiovascular disease and stroke. Trans fats are often found in deep-fried foods, which are generally high in calories and low in nutritional value. Therefore, it is recommended to consume such foods sparingly.
On the other hand, monounsaturated and polyunsaturated fats are considered healthy. These fats can be found in liquid non-tropical plant oils such as canola, soybean, corn, safflower, sunflower, and nut oils. Consuming these fats can help lower "bad" LDL cholesterol levels, promoting heart health.
Additionally, some saturated fat can be part of a healthy diet. The current recommendation is to limit saturated fat to about 10% or less of your total calorie intake. Sources of saturated fat include meat, dairy products, and some plant foods like palm oil and coconut oil.
When incorporating healthy fats into your diet, it is important to consider your overall calorie intake and physical activity level. Fats are energy-dense, with 9 calories per gram, compared to 4 calories per gram for carbohydrates and protein. Therefore, consuming too many calories, even from healthy fats, can contribute to weight gain.
