Nutrition

Nutrition is the science that interprets the interaction of nutrients and other substances in food in relation to maintenance, growth, reproduction, health, and disease of an organism. It includes the processes by which the human body ingests, digests, absorbs, transports, utilizes, and excretes food substances.

Key Concepts in Nutrition

There are several key concepts in nutrition that are essential to understand:

1. Nutrients: Nutrients are the substances found in food that are essential for growth, energy production, and overall health. They include carbohydrates, proteins, fats, vitamins, and minerals.
2. Macronutrients: These are nutrients that are required in large amounts by the body and include carbohydrates, proteins, and fats.
3. Micronutrients: These are nutrients that are required in smaller amounts by the body and include vitamins and minerals.
4. Calories: Calories are a measure of the energy provided by food and are essential for maintaining bodily functions and physical activity.
5. Dietary Guidelines: These are evidence-based recommendations for a healthy diet provided by government agencies or health organizations.
6. Healthy Eating Patterns: These patterns emphasize a variety of nutrient-dense foods, within calorie needs, to support overall health.
7. Food Labels: Understanding food labels can help individuals make informed choices about the foods they consume, by providing information about serving sizes, calories, and nutrient content.
