A new global study warns that climate change is significantly reducing the nutritional value of staple crops, threatening to worsen food insecurity worldwide.
The research highlights a growing phenomenon known as "hidden hunger," where populations consume sufficient calories but lack essential vitamins and minerals.
Prof. Asaph Aharoni, an Israeli expert involved in the study, emphasized the immediacy of the threat.
According to the findings, up to two-thirds of the world's population already suffers from micronutrient deficiencies, a problem that is accelerating as rising carbon dioxide levels and extreme weather patterns alter plant biology.
Prof. Asaph Aharoni, an Israeli expert involved in the study, emphasized the immediacy of the threat.
"This is not a distant threat to health," he stated, noting that the degradation of food quality is already impacting public health outcomes.
The study suggests that while global attention has focused on crop yields and caloric availability, the declining nutrient density of food represents a critical, underappreciated dimension of the climate crisis.
The findings come as global efforts to curb carbon emissions continue to fall short.
