Nutrition and Metabolism: Fueling the Body for Health and Energy

What Is Nutrition?

Nutrition is the science of food. It studies how nutrients support growth and health. Proteins, carbohydrates, fats, vitamins, and minerals are essential. Water is also vital for every body function.

What Is Metabolism?

Metabolism is how the body converts food into energy. It includes catabolism (breaking down food) and anabolism (building new cells). A healthy metabolism keeps energy levels stable. It also supports repair, immunity, and hormone balance.

How Nutrition Affects Metabolism

• Proteins build muscles and enzymes.
• Carbohydrates provide quick energy.
• Fats store energy and support brain health.
• Vitamins and minerals regulate chemical reactions.
• Fiber improves digestion and gut health.

Factors That Influence Metabolism

• Age: metabolism slows with age.
• Gender: men often have higher metabolic rates.
• Muscle mass: more muscle means faster calorie burn.
• Hormones: thyroid and insulin play key roles.
• Physical activity: exercise boosts metabolism.

Nutrition Tips for a Healthy Metabolism

• Eat balanced meals with all macronutrients.
• Stay hydrated throughout the day.
• Include lean proteins in every meal.
• Choose whole grains over refined carbs.
• Add fruits and vegetables for vitamins and antioxidants.
• Avoid excess sugar and processed foods.

Common Metabolic Disorders

• Obesity from excess calorie intake.
• Diabetes from poor insulin regulation.
• Thyroid disorders affecting energy balance.
• Metabolic syndrome linked to heart disease and stroke.
