Overlooked Water Plant Holds Promise in Combating Food Insecurity

Carolina Azolla: A Promising Solution for Food Insecurity | The Lifesciences Magazine


Unveiling the Potential

A study led by researchers at Penn State University sheds light on the promising role of Carolina Azolla, an often-overlooked water plant native to the eastern U.S., in addressing food insecurity. Known for its rapid growth rate and ability to capture nitrogen from the air, Carolina Azolla has been identified as a valuable source of nutrition for both humans and livestock. Published in Food Science & Nutrition, the study underscores the plant’s potential to serve as a life-saving food resource in times of catastrophe or disaster.

Nutritional Benefits and Cultivation

Carolina azolla’s nutritional profile surpasses that of other azolla varieties cultivated in Asia and Africa, making it more digestible and nutritious for human consumption. Despite its high polyphenolic content, which can hinder nutrient absorption, the Carolina strain exhibits lower levels, rendering it suitable for consumption after cooking. The researchers conducted greenhouse experiments at Penn State’s University Park campus to evaluate the plant’s phenolic content and tested various cooking methods to reduce antinutritional factors.

Implications for Food Resilience

The study highlights Carolina Azolla as a potential solution to food insecurity, particularly in disaster-prone regions. Its fast-growing nature and minimal processing requirements make it an ideal crop for smallholder farms and low-income areas. Moreover, its cultivation could offer a climate-resilient source of nutrition during emergencies. The researchers emphasize the need for further development and efficiency in azolla cultivation and preparation to maximize its economic, agricultural, and nutritional benefits.

The findings contribute to ongoing efforts to enhance food resilience amidst increasing environmental challenges. By exploring the viability of lesser-known food sources like Carolina Azolla, researchers aim to bolster the resilience of food systems and mitigate the impact of disasters on global food security.
