How to Eat a Balanced Diet

1. Fruits and Vegetables


Why is it important

A variety of fruits and vegetables provides the body with vitamins, minerals, and antioxidants, which are important in maintaining health and preventing disease. Their low fat and high water content make them a good choice for healthy snacks. Research shows that a balanced diet rich in fruits and vegetables prevents diseases such as heart disease and cancer.

Experts recommend eating at least five portions of various fruits and vegetables per day, consisting of different colors to obtain a variety of nutrients.


Fruits and vegetables may be eaten as snacks or incorporated into vegetable soups, smoothies, juices, salads, or other foods. They are best eaten raw, but some may be cooked by steaming or baking.

2. Proteins


Why is it important

Why is it important to have a balanced diet with protein in it? Proteins are important for body growth and tissue repair as well as healing of injuries. A lack of protein in the diet can result in muscle deterioration, heart problems, arthritis, muscle soreness, cramps, hair loss, loss of sleep, and poor wound healing.

How much to have

Experts recommend a daily intake of 45g of protein for adult women and about 55.5g for men. People who exercise regularly or are trying to build more muscle may need more protein in their diet.


Foods rich in protein include meat, poultry, seafood, eggs, nuts, seeds, and soy products. Animal products provide complete source of all amino acids, which promote growth but they also contain high levels of fat. Oily fish are good sources of protein and omega-3 fatty acids, which are important to prevent heart disease. Other sources of proteins include plant-based products, which contain less fat.

How much to have

Experts recommend that about one-third of every meal you eat must consist of carbohydrates. Carbohydrates contain fewer calories compared to protein and fat, so they should be included in a balanced diet.


Complex carbohydrates from vegetables, such as potatoes, legumes and lentils, nuts, and whole-grain cereals such as whole grain pasta and brown rice, are great sources of carbohydrates. Simple sugars found in snack bars, cakes, chocolate, and pastries must be avoided.

For adults experts recommend taking three portions of dairy a day. Low-fat dairy are good for those who want are concerned with fat intake. One can have 200ml milk or 250ml soya-milk plus calcium, 30g of cheese, and one cup of yogurt. Children and teens must get plenty of dairy for good bone development.


Healthful dairy products include milk, yogurt, cheese, and fromage frais. However, butter and cream must be avoided. Vegans or lactose intolerant individuals can take calcium-fortified soymilk and yogurt.
