Reading Passage: Nutritional Facts of Water
(A) Water, often referred to as the “elixir of life,” is a fundamental component of human survival. Unlike other food and beverages, water does not contain calories, fats, proteins, or carbohydrates. Instead, its nutritional value lies in its ability to support essential bodily functions. Water plays a key role in hydration, temperature regulation, and the transportation of nutrients and waste. It is indispensable for maintaining overall health and well-being.
(B) Despite its importance, many people face challenges in maintaining proper hydration. One common problem is not drinking enough water daily, leading to dehydration. This can cause symptoms such as fatigue, headaches, and reduced cognitive function. Another issue is overhydration, which can dilute essential electrolytes and disrupt body balance. Solutions include tracking daily water intake and consuming electrolyte-enriched beverages when necessary. Ensuring access to clean and safe drinking water is also critical in addressing hydration challenges globally.
(C) The benefits of drinking water are vast. Proper hydration improves energy levels, supports skin health, and enhances physical performance. Drinking water aids in digestion by helping to break down food and absorb nutrients. Additionally, it prevents kidney stones and helps regulate blood pressure. However, excessive water intake can pose risks, such as water intoxication, emphasizing the need for moderation.
(D) Studies highlight the significant role of water in health. Research shows that drinking the recommended 8-10 cups (2-2.5 liters) of water daily can reduce the risk of chronic diseases like kidney stones and urinary tract infections by up to 30%. Surveys indicate that over 70% of individuals fail to meet their daily hydration needs. In 2023, it was reported that global water consumption had risen by 25% in the last decade, reflecting increased awareness of its benefits.
(E) The process of hydration involves several stages. When water is consumed, it is absorbed in the small intestine and enters the bloodstream. From there, it is distributed to tissues and cells, enabling them to perform essential functions. Excess water is filtered by the kidneys and excreted as urine, maintaining the body’s fluid balance. Regular water consumption is vital for keeping this process efficient and preventing dehydration or fluid retention.
