In 1965, a team of scientists developed Gatorade for the University of Florida football team. This innovative sports drink, despite its complex ingredient list, fits into one primary category when classifying matter: a homogeneous mixture.

According to chemists, a sports drink is a homogeneous mixture, specifically a solution, because its components are uniformly distributed throughout. When you drink it, every sip contains the same balance of water, sugars, and electrolytes, making it visually and chemically consistent.

Glucose, a monosaccharide with the chemical formula C6H12O6, has a fixed and uniform composition throughout its molecular structure. In chemistry, this precise consistency is the defining characteristic that classifies it as a pure substance, setting it apart from common everyday mixtures.

According to the World Health Organization, alcohol consumption contributes to 2.6 million deaths each year globally, highlighting its significant impact. This psychoactive substance is the active ingredient in alcoholic drinks, but is an alcoholic drink a substance or mixture from a chemical perspective? The definitive answer depends on the context: pure ethanol is a substance, but the beverages we consume are mixtures.

Chemically, baking soda is sodium bicarbonate ($NaHCO_3$), a compound that contains sodium but is fundamentally different from the pure, highly reactive element sodium itself. A single teaspoon of baking soda contains about 1,260 mg of sodium, yet it is a stable, safe household ingredient.

Chemically, table sugar, or sucrose, is a pure substance with the formula C₁₂H₂₂O₁₁. Given this, the question arises: **is sugar considered a substance** from a nutritional and chemical standpoint, and how does this affect diet?
