A healthy diet is one of the most important foundations of good health. Eating a balanced variety of nutritious foods can support overall well-being and help reduce the risk of conditions such as heart disease, diabetes, stroke, and certain cancers. According to the World Health Organization (WHO), a healthy diet is based on adequacy, balance, moderation, and variety.

What Is a Healthy Diet?

A healthy diet does not mean following a strict or complicated meal plan. Instead, it means regularly choosing a variety of nutritious foods, including:

• Fruits and vegetables
• Whole grains
• Beans, lentils, and other legumes
• Nuts and seeds
• Lean sources of protein
• Healthy sources of dietary fats

The right balance can vary depending on a person’s age, lifestyle, activity level, and individual nutritional needs.

Why Are Fruits and Vegetables Important?

Fruits and vegetables provide important vitamins, minerals, antioxidants, and dietary fibre. WHO recommends that people over the age of 10 aim for at least 400 grams of fruits and vegetables each day.

An easy way to increase your intake is to add vegetables to your main meals and choose fresh fruit or vegetables as snacks instead of highly processed foods.

Limit Excess Sugar and Salt

Eating too much added or “free” sugar can contribute to unhealthy weight gain and increase the risk of dental problems. WHO recommends keeping free sugars below 10% of total daily energy intake, with further reduction potentially providing additional health benefits.

Salt intake is another important consideration. Adults should generally consume less than 5 grams of salt per day. High sodium intake can contribute to increased blood pressure and raise cardiovascular risk.

Choose More Whole and Minimally Processed Foods

Whole grains, vegetables, fruits, legumes, nuts, and other minimally processed foods can form the foundation of a balanced eating pattern. Highly processed foods that are high in salt, free sugars, and unhealthy fats should be limited.

Small changes can make a difference. For example, you can choose whole-grain foods more often, add vegetables to meals, reduce sugary drinks, and check food labels for sodium and added sugars.

The Bottom Line

Healthy eating is not about perfection. It is about making better choices consistently. A varied diet rich in nutritious foods, combined with regular physical activity and other healthy lifestyle habits, can support long-term health.
