Abstract Summary

Objective: To investigate the presence of electrolytes in lemons and their potential role in hydration and electrolyte balance.

Context: Electrolytes are essential minerals that help maintain fluid balance, muscle function, and other critical physiological functions. Common electrolyte sources include certain fruits, vegetables, and beverages. Lemons, though often associated with high vitamin C content, have also been noted for their mineral composition, raising the question of whether they contribute electrolytes when consumed.

Methods Used

Approach: A literature review of studies examining the mineral and electrolyte composition of citrus fruits, particularly lemons. Research focused on identifying potassium, calcium, magnesium, and sodium as primary electrolytes within the fruit.

Data Collection: Studies from scientific journals and nutritional databases were reviewed. Analytical studies using techniques like atomic absorption spectroscopy and flame photometry were included to verify mineral content in lemons.

Researchers' Summary of Findings

The analysis of lemons indicated that they contain notable levels of potassium, a key electrolyte, with smaller amounts of calcium and magnesium. While these electrolytes are present in lesser quantities than in more concentrated sources (like bananas or electrolyte drinks), lemons can contribute to overall electrolyte intake, especially when combined with other electrolyte-rich foods.
