FOOD AND NUTRITION
FOOD AND NUTRITION
Food refers to any substance consumed to provide nutritional support for the body. It contains essential nutrients such as carbohydrates, proteins, fats, vitamins, and minerals, which are necessary for growth, maintenance, and repair of tissues. Beyond its nutritional value, food also plays cultural, social, and emotional roles in different societies.
NUTRITION:
Nutrition is the science that interprets the interaction of nutrients and other substances in food with our bodies. It encompasses the processes by which we ingest, digest, absorb, transport, utilize, and excrete food substances. Good nutrition is crucial for maintaining optimal health and preventing diet-related diseases.
Understanding food and nutrition involves knowledge of dietary patterns, nutrient requirements, dietary guidelines, and the impact of various foods on health outcomes. It also considers factors such as food safety, sustainability, and the cultural significance of different dietary practices.
In summary, food and nutrition are integral to our overall health and quality of life, influencing our physical, mental, and social well-being
