The nutritional value of crops like wheat and rice has decreased over the past sixty years due to factors like the Green Revolution, climate change, and the use of hybrid crops.
These factors have resulted in larger crops with lower mineral content, leading to "micronutrient malnutrition" in many people, especially in low-income countries.
To compensate for the decrease in nutritional value, it is recommended to follow dietary guidelines and consume a higher proportion of fruits and vegetables. However, as CO₂ levels rise, even greater amounts of these foods may be necessary to obtain adequate minerals.
There is concern about the decreasing nutritional value of crops and its potential impact on human health.
Potential solutions discussed include organic farming, regenerative agriculture, and the use of human waste as fertilizer.
The debate also touches on the impact of monoculture farming, changes in consumption patterns, and the importance of macronutrients and micronutrients in maintaining a balanced diet. Further research and the complexity of the food system are highlighted.
