The History and Evolution of a Balanced Diet

The concept of a balanced diet has evolved over millennia, blending traditional knowledge with scientific advancements to optimize health. Its development reflects cultural practices, technological innovations, and a growing understanding of nutrition’s role in well-being.

Origins and Early Dietary Practices

Dietary balance has roots in ancient civilizations, where food was linked to survival, spirituality, and health:

Prehistoric Era (c. 10,000 BCE): Hunter-gatherers consumed diverse diets of wild plants, meats, and nuts, with 70% of calories from foraged foods, per archaeological evidence. These diets, naturally balanced, supported 1 million global populations.
Ancient Civilizations (c. 3000 BCE–500 CE): Egyptians balanced grains, fruits, and fish, with 5,000 recipes in texts like the Ebers Papyrus. In India, Ayurveda promoted balanced doshas through diet, documented in 3,000 texts, influencing 1 billion by 2025.
