People often say, “You are what you eat.” Today, science shows this is true. Functional nutrition means food is not just about filling your stomach or giving you energy. Different foods can help your body in special ways they can make your tummy stronger, keep your mind calm, fight sickness, and give you more energy. Instead of just following a regular diet, food-as-medicine is about eating natural foods, fruits, herbs, and spices that can keep you healthy and even help you feel better when you are sick.

What is Functional Nutrition?

Functional nutrition is a way of eating that is made just for you. It doesn’t only look at proteins, carbs, and fats. It also studies.

• Special helpers in food like vitamins, antioxidants and natural plants that give your body extra strength.
  
• Good bacteria in your tummy that help with digestion, mood and staying healthy.
  
• Differences in people – like family background, where you live and how you live your life.
  

So, it’s not just about eating “healthy” food. It’s about choosing the right foods for your body so you can stay balanced and healthy for a long time.
