According to the World Health Organization, vitamin A deficiency is a public health problem in more than half of all countries, particularly impacting young children and pregnant women. Understanding what causes a lack of vitamin A is crucial for prevention and mitigating its severe health consequences, including childhood blindness.

The World Health Organization estimates that between 250,000 and 500,000 vitamin A-deficient children become blind every year, with half of them dying within 12 months. Golden rice is a genetically engineered crop designed to provide a sustainable, food-based solution to this public health crisis by addressing vitamin A deficiency (VAD) in vulnerable populations.

According to the World Health Organization (WHO), vitamin A deficiency affects approximately 190 million preschool-aged children worldwide, especially in low-income countries. This nutrient is essential for their rapid growth, healthy immune system, and proper vision, making it important to give vitamin A to the children through diet or supplementation.

Did you know that research focusing specifically on vitamin A2 is significantly more limited than research on the more common vitamin A1? Understanding what disease is caused by vitamin A2 deficiency first requires a deeper look into the various forms of vitamin A and their specific roles in the body.

Globally, vitamin A deficiency (VAD) is the leading cause of preventable childhood blindness, with an estimated 250,000 to 500,000 children becoming blind each year due to this condition. Clinical vitamin A deficiency occurs when the body's vitamin A reserves are critically low, leading to distinct, often severe, health problems. This critical nutrient is vital for vision, immune function, reproduction, and cell growth.

According to the World Health Organization, 250,000–500,000 children worldwide lose their sight each year due to vitamin A deficiency, a problem Golden Rice was developed to combat. So, what vitamins are in Golden Rice and how does it help?

Worldwide, between 250,000 and 500,000 children become blind each year due to vitamin A deficiency, one of the primary meanings of the acronym VAD. Understanding what disease is VAD requires recognizing that this short-hand term can represent different medical conditions or a mechanical device, causing frequent confusion.

An estimated 190 million preschool-aged children are vitamin A deficient globally, leading to increased risk of illness, blindness, and mortality. The vitamin A process program is a comprehensive public health framework designed to eliminate this nutritional problem through strategic, multi-pronged interventions.

According to a 2019 study, an estimated 14.73% of children and adolescents in low- and middle-income countries were deficient in vitamin A, with the prevalence being significantly higher in younger age groups. This nutrient deficiency is a major global public health concern, with vast disparities based on geography and socioeconomic factors.

According to a 2023 study focusing on low and middle-income countries (LMICs), an estimated 333.95 million children and adolescents were affected by vitamin A deficiency in 2019. This critical statistic prompts the question: What percentage of people have vitamin A deficiency globally, and how does this vary by region?
