A recent study published in The Lancet Global Health journal highlights a significant deficiency in essential micronutrients among Indians. According to the research, people across all age groups in India are consuming inadequate amounts of critical micronutrients such as iron, calcium, and folate. This study is the first of its kind to provide estimates on the insufficient consumption of 15 micronutrients across 185 countries, relying solely on dietary intake data without accounting for supplements.
The study, conducted by an international team that includes researchers from Harvard University, reveals a global trend where approximately 70% of the population, or over five billion people, do not consume sufficient amounts of iodine, vitamin E, and calcium. Within individual countries and age groups, the deficiency patterns vary. For instance, in general, more women are found to have inadequate levels of iodine, vitamin B12, and iron, whereas men are more likely to suffer from deficiencies in magnesium, vitamin B6, zinc, and vitamin C.
In India, the findings indicate that while women generally consume insufficient amounts of iodine, men are more likely to have inadequate levels of zinc and magnesium. The study also notes that men and women aged 10-30 years are particularly prone to low calcium intake, especially in regions like South Asia, Southeast Asia, and sub-Saharan Africa.
The researchers utilized publicly available data from the Global Dietary Database to estimate the prevalence of insufficient nutrient intake, covering 99.3% of the global population. Despite extensive analyses over the past decade addressing micronutrient deficiencies, significant data gaps remain for various micronutrients and demographic groups.
The study’s results are intended to assist public health professionals in identifying and targeting populations that require dietary interventions. However, the authors caution that the study may overestimate deficiencies for certain key nutrients, particularly in areas where high consumption of fortified foods and supplements may mitigate these deficiencies.
Overall, the study underscores a critical public health issue and emphasizes the need for improved dietary strategies to address micronutrient deficiencies globally.
