Rice, a cereal grain and dietary cornerstone for over half the global population, traces its domestication in Asia back 13,500 to 8,200 years ago, with African rice emerging independently around 3,000 years ago. Remarkably, there exist more than 120,000 rice varieties cultivated worldwide, showcasing endless diversity across grain size, color, starch type, and culinary use. 

Beyond its ubiquity, rice holds rich cultural and religious symbolism. In India, it is revered in Vedic texts, woven into rituals, festivals like Pongal and Bihu, and life ceremonies from naming rituals to wedding blessings.

On the nutrition front, rice offers a reliable energy source. Whole-grain types like brown rice deliver significant amounts of fiber, protein, antioxidants, and micronutrients such as B-vitamins, magnesium, and iron. White rice, though refined, provides quick-digesting carbohydrates, essential B-vitamins, and iron when enriched. Both varieties are naturally gluten-free, benefiting those with food sensitivities. Nutritional profiles vary widely depending on type and cooking methods.
