Regular physical activity and a healthy diet can prevent many chronic diseases like diabetes, heart disease, and cancer. The World Health Organization says that by improving daily habits, we could avoid:

• 80% of coronary heart disease, stroke, and type 2 diabetes
• 40% of all cancers

Studies show that exercise helps by lowering blood pressure, improving insulin sensitivity, and boosting the immune system.

Physical activity doesn’t just prevent disease—it helps people manage symptoms too. People with diabetes can control their blood sugar better. Heart patients experience better heart function. Cancer patients may feel stronger and less fatigued.

Eating well matters just as much. Diets high in vegetables, fruits, whole grains, and healthy fats help fight inflammation and improve metabolism. On the other hand, diets full of sugar, processed foods, and trans fats can lead to obesity and disease.

One of the best diets is the Mediterranean Diet, which includes:

• Olive oil
• Fish
• Fruits and vegetables
• Whole grains

This diet is linked to a lower risk of stroke and heart disease.
