Do you plan to change how much fruit and vegetables you eat due to nutrient concerns?
Deep Science Ventures reports that common food items have lost 20 to 50 percent of their key nutrients since the 1960s. This decline is attributed to intensive agricultural practices that boosted cereal yields but resulted in degraded soil organic matter.
Why it matters
While global undernutrition rates have dropped, 2 billion people still suffer from micronutrient deficiencies. Restoring soil health could be critical to improving the nutritional density of the global food supply.
A report from Deep Science Ventures notes that common foods have lost 20 to 50 percent of their key nutrients over six decades, even as cereal yields increased by 215 percent. Meanwhile, 2 billion people globally currently suffer from at least one clinical micronutrient deficiency.

The details
Researchers found that crops grown in soil with higher organic matter levels consistently contained higher concentrations of essential nutrients. Previous studies, including a 2017 meta-analysis and a 2021 study in Circulation, have linked daily fruit and vegetable intake to lower mortality and disease risks.

2017: Publication of a meta-analysis on fruit and vegetable intake.
2021: Publication of a study in Circulation concerning mortality risk.

Health Landscape
This finding complicates the health benefits observed in the 2017 fruit and vegetable intake meta-analysis by suggesting the nutrient density of those portions has likely diminished. It highlights a shift in focus from mere caloric output to the long-term biological quality of the global diet.
The study suggests that individuals may need to consume more diverse or high-quality produce to achieve the same nutrient intake levels seen in the past. It underscores the potential importance of soil health and agricultural quality as factors in daily wellness and long-term health.
The takeaway
Consumers can prioritize produce grown with sustainable practices to potentially gain better nutrient density. Increasing the daily intake of fruits and vegetables remains a verified strategy to mitigate long-term mortality and disease risk.
