Contrary to the popular single 'caveman diet' idea, evidence shows that early human diets were incredibly diverse and varied significantly by geography, climate, and season. The question of what was the original diet leads to a complex tapestry of plant and animal foods consumed over millions of years.

Earliest archaeological evidence from Ethiopia indicates our ancestors were butchering animals with stone tools as far back as 2.6 million years ago. This initial foray into carnivory marks the beginning of the long evolutionary journey to understand when did eating meat become common.

First published in 1992 by the USDA, the Food Guide Pyramid offered a visual guide to a healthy daily diet based on relative proportions of food groups. This graphic symbolized **what did the food pyramid used to represent how much the average American should consume** by assigning a range of daily servings for each food category.

The 2000-calorie diet isn't a strict dietary rule but rather a benchmark for food labeling that emerged in the 1990s following the Nutrition Labeling and Education Act. This standard was created to simplify food labels for consumers, allowing for consistent comparisons of nutrients and health claims.

The modern term 'vegan' was coined in 1944, and archaeological evidence confirms that no entire ancient tribe practiced a purely vegan lifestyle, though many groups subsisted on predominantly plant-based diets for various reasons.

Scientific analysis of food and nutrients began during the chemical revolution in the late 18th century, leading to the early concept of a nutrient theory that centered on isolating individual components. This article delves into this foundational, reductionist approach and traces its evolution into the complex understanding of nutrition we have today.

In 1968, the American Heart Association recommended restricting egg consumption due to concerns over cholesterol. This decision marked a turning point, causing many to question, 'when did eggs become bad for you?' for nearly half a century, before scientific understanding evolved.

In 1968, the American Heart Association recommended limiting eggs to just three per week due to cholesterol fears. This public health stance marked the start of a decades-long debate, but a fascinating journey of scientific revision reveals the true story of when did eggs become healthy.

For thousands of years, ancient humans were consuming dairy long before the genetic mutation for digesting milk became widespread. This raises the intriguing question: Were humans drinking milk before they could digest it? The answer is a fascinating tale of cultural ingenuity and evolutionary pressure.

In 1977, the term **complex carbohydrate** was introduced by a U.S. Senate committee to distinguish nutritionally superior foods like whole grains and vegetables from processed sugars. This origin story reveals a purpose more dietary than purely chemical.
