1. Eat a Balanced, Nutrient-Rich Diet

A healthy diet is the cornerstone of disease prevention. Consuming a variety of whole foods provides essential vitamins, minerals, and antioxidants that protect against illness.

Key Dietary Tips:

• Fill half your plate with fruits and vegetables – They are rich in fiber, vitamins, and antioxidants.
• Choose whole grains – Opt for brown rice, quinoa, and whole wheat over refined grains.
• Prioritize lean proteins – Include fish, poultry, beans, and nuts while limiting red and processed meats.
• Healthy fats are essential – Avocados, olive oil, and fatty fish (like salmon) support heart health.
• Limit sugar and processed foods – Excess sugar contributes to obesity, diabetes, and inflammation.

Disease-Fighting Foods:

• Berries (high in antioxidants)
• Leafy greens (rich in vitamins A, C, and K)
• Garlic and turmeric (anti-inflammatory properties)
• Nuts and seeds (packed with healthy fats and fiber)

Exercise Recommendations:

• 150 minutes of moderate aerobic activity per week (e.g., brisk walking, cycling).
• Strength training 2x per week (to maintain muscle mass and bone density).

Tobacco use is a leading cause of cancer, lung disease, and heart attacks. Excessive alcohol consumption harms the liver and increases disease risk.

Healthy Habits:
