3. Introduction 3 A critical aspect of our lives that affects us all - the food we consume. From the farmers who grow it to the families who enjoy it, food plays a vital role in nourishing our bodies and sustaining our communities. The safety and nutritional value of the food we eat are fundamental factors that directly impact our health, well-being, and overall quality of life. Safe and nutritious food is the cornerstone of good health, providing essential nutrients that support physical and mental well-being. A balanced diet is not only crucial for growth and development but also helps prevent a range of diet-related diseases. Unfortunately, unsafe and inadequate nutrition can lead to serious health issues and hinder socio-economic development.

9. Basic Concepts of Nutrition and Safe Foods 9

10. Why is Nutrition Important? 10 Nutrition is the process of providing the body with the necessary nutrients to support growth, development, and overall health. Proper nutrition is vital for maintaining a strong immune system, enhancing physical and mental performance, and preventing diseases.

11. Consequences of Poor Nutrition 11 Malnutrition deficiencies in essential nutrients, and increased susceptibility to illnesses. Reduced Energy Levels fatigue, decreased stamina, and decreased work performance. Impaired Cognitive Function decreased concentration, weak memory, and poor decision-making abilities.

12. Concept of Safe and Nutritious Food 12 Safe and nutritious food refers to food that is not only free from harmful contaminants and hazards but also provides the necessary nutrients for maintaining good health and well-being. It encompasses the idea of food security, which means that all individuals have access to sufficient, safe, and nutritious food that meets their dietary needs.

13. 1. Safety Safe food means that it is free from contaminants, pathogens, toxins, and other harmful substances that can cause foodborne illnesses. Food safety involves proper handling, storage, preparation, and processing of food. 13

14. 2. Nutritional Value Nutritious food is rich in essential nutrients, including proteins, carbohydrates, healthy fats, vitamins, and minerals. Nutrients are necessary for growth, development, and maintenance of bodily functions. It should provide a balanced combination of nutrients to meet the specific dietary requirements of individuals at different life stages. 14

15. 3. Quality Quality food refers to food that meets established standards for taste, appearance, texture, and other sensory attributes. It should be fresh, flavorful, and free from spoilage. Quality food also encompasses factors such as ethical sourcing, sustainability, and animal welfare considerations. 15

16. It promotes a balanced intake of fruits, vegetables, whole grains, lean proteins, and healthy fats. 16 4. Dietary Diversity A diverse diet includes a wide variety of foods from different food groups, ensuring a range of nutrients and reducing the risk of nutrient deficiencies.

17. It involves ensuring that food is available, physically and economically accessible, and affordable. This includes addressing issues of food deserts, poverty, and inequality in food distribution. 17 5. Access and Affordability Safe and nutritious food should be accessible to all individuals, regardless of their socio-economic status.

18. Role of Safe and Nutritious Food in Maintaining Optimal Health and Well-being 18 Safe and nutritious food provides the necessary nutrients, supports immune function, prevents diseases, promotes energy, and contributes to overall physical and mental wellness. A balanced and diverse diet is key to reaping these benefits and leading a healthy lifestyle.

19. Nutrition and Productivity 19

20. The Link between Nutrition and Productivity 20 1. Improved Cognitive Function Leads to better focus, concentration, and problem-solving skills. Because the brain needs certain nutrients to function properly. For example, omega-3 fatty acids, found in fish and nuts, are essential for brain health. 2. Increased Energy Levels Healthy foods lead to greater productivity with the provision of energy-yielding nutrients. For example, complex carbohydrates, found in whole grains, fruits, and vegetables, are a slow-burning source of energy that can help to keep you feeling energized throughout the day.

21. 3. Reduced Stress Levels Eating a healthy diet can help to reduce stress levels. This is because stress can interfere with cognitive function and make it difficult to focus. Healthy foods, such as fruits, vegetables, and whole grains, are rich in nutrients that help to reduce stress. 4. Better Mood Eating a healthy diet can help to improve mood. Mood and productivity are closely linked. Healthy foods, such as fruits, vegetables, and whole grains, are rich in nutrients that help to improve mood. 21

22. Effects of Poor Nutrition on Productivity 22 Empirical findings include: The world is facing a "food gap" of staggering proportions, with one out of six people on the planet undernourished, and an equal number overweight or obese. Inadequate nourishment can cut productivity by up to 20% . In 2001, non-communicable (diet-related) diseases contributed to about 46% of the global disease burden. The global burden of diet-related diseases has climbed to 57% in 2020. In Southeast Asia, iron deficiency accounts for a US$5 billion loss in productivity.

23. In India, the cost of lost productivity, illness and death due to malnutrition is US$10 to 28 billion , or 3 to 9% of GDP . In wealthier nations, obesity accounts for 2 to 7% of total health costs: in the USA the annual economic cost of obesity is US$12.7 billion . In the USA, malnutrition costs approximately US$3.9 billion due to lost productivity - reflected in 39.2 million lost work-days , 239 million restricted-activity days , 89.5 million bed-days and 62.6 million physician visits . In the developing world , a 1% kilocalorie (kcal) increase results in a 2.27 per cent increase in general labour productivity. 23

24. Conclusion 24 The significance of safe and nutritious food extends beyond individual health. A well-nourished population leads to stronger communities and increased productivity, contributing to economic growth and stability. A sustainable food system, focusing on safety and nutrition, plays a vital role in achieving the United Nations' Sustainable Development Goals. By promoting responsible agricultural practices and reducing food waste, we can work towards a more resilient and equitable future.
