An alarming decline in the nutritional quality of foods has become a major challenge for future generations' health. Over the past 60 years, there has been a significant decrease in the nutritional content of essential fruits, vegetables, and food crops. This decline is attributed to factors such as chaotic mineral nutrient application, the preference for less nutritious cultivars, the use of high-yielding varieties, and the shift from natural to chemical farming. Additionally, increased atmospheric carbon dioxide levels have contributed to reduced nutritional quality. Traditional nutrient-rich crops like millets, conventional fruits, and vegetables have been replaced by less nutritious crops due to their economic competitiveness. Many people in underdeveloped and developing countries suffer from malnutrition and nutrient deficiencies due to poor dietary habits and a lack of awareness about traditional diets and organic farming. The review emphasizes the importance of balanced nutrition, soil biodiversity, and fertility to maintain nutritional density. It also highlights the need for strategies to improve the nutritional quality of food crops for future generations. The causes of declining nutrient density include soil degradation, the use of synthetic fertilizers, climate change, and elevated carbon dioxide levels. The review also discusses the impact of agricultural practices, postharvest handling, and the decline in arable land. The management strategies include reviving traditional foods, improving soil nutrient management, promoting organic farming, and integrating various approaches to enhance the nutritional density of crops. The review concludes that a combination of these strategies is essential to address the challenges of declining nutritional quality and ensure future food security.An alarming decline in the nutritional quality of foods has become a major challenge for future generations' health.
