Can Regenerative Agriculture Improve Food Nutrients?

Over the years, our food has become less nutritious. For example, the vitamin C in lemons has dropped by almost a third. Some scientists believe regenerative agriculture can help. This method focuses on improving soil health and increasing biodiversity, which may lead to better nutrition in crops.

In recent decades, the nutrient content of crops has significantly declined. Research shows that vitamin C in lemons decreased by nearly one-third and calcium in carrots dropped by more than a quarter. Regenerative agriculture, which emphasizes rebuilding soil health and biodiversity, may be a promising solution. Studies indicate that crops from regenerative farms can have much higher nutrient levels compared to conventional farms, potentially improving the nutritional quality of our food.

The nutrient content of crops has been on a worrying decline for several decades. For instance, the US Department of Agriculture reported that the vitamin C content in lemons fell by almost one-third from the late 1970s to the late 1990s, while calcium levels in carrots decreased by over 25%. Factors contributing to this decline include faster-growing crop varieties and increased carbon dioxide levels, which lead to higher sugar and starch production but lower nutrient density. However, regenerative agriculture, which focuses on enhancing soil health and biodiversity, may provide a viable solution. Research indicates that crops grown using regenerative practices can exhibit significantly higher nutrient levels, such as iron in kale being up to 22 times higher than conventional methods.
