Sports Drinks: replace Electrolytes lost through sweat

Electrolytes are minerals that carry an electric charge when dissolved in a liquid, such as bodily fluids. They play a crucial role in maintaining proper hydration, nerve function, muscle contractions, and overall body balance. Here’s why electrolytes matter:

  1. Fluid balance: Electrolytes, such as sodium, potassium, and chloride, help regulate the balance of fluids in your body. They help maintain the right amount of water inside and outside your cells, ensuring proper hydration and cellular function.
  2. Nerve function: Electrolytes are essential for transmitting electrical signals along nerves. They help generate and regulate nerve impulses, which are crucial for proper muscle function, including the contraction and relaxation of muscles.
  3. Muscle function: Electrolytes, especially calcium, magnesium, and potassium, are vital for muscle contractions. They allow muscles to contract and relax properly, including the muscles involved in physical activity, heartbeats, and even digestion.
  4. pH balance: Electrolytes also contribute to maintaining the body’s acid-base balance, or pH level. They help regulate the pH of bodily fluids, including blood, which is essential for normal cellular function.
  5. Hydration: When you sweat or lose fluids through other means, you not only lose water but also important electrolytes. Replenishing electrolytes is essential to restore and maintain proper hydration levels. This is particularly important during intense physical activity, hot weather, or if you’re experiencing conditions that cause excessive sweating or fluid loss, such as vomiting or diarrhoea.
  6. Energy production: Electrolytes, particularly phosphates, play a role in energy metabolism. They are involved in the production, storage, and release of energy in cells.

Common electrolytes include sodium, potassium, chloride, calcium, magnesium, and phosphate. You can obtain electrolytes through a balanced diet that includes foods like fruits, vegetables, nuts, seeds, whole grains, and dairy products. Additionally, electrolyte-rich sports drinks or electrolyte supplements can be beneficial during periods of intense physical activity, prolonged sweating, or fluid loss.


Sources of electrolytes:

Electrolytes can be obtained from various food and beverage sources. Here are some common sources of electrolytes:

  1. Sodium: Table salt (sodium chloride), pickles, olives, canned soups, processed meats, soy sauce, and sports drinks.
  2. Potassium: Bananas, oranges, avocados, tomatoes, sweet potatoes, spinach, yogurt, salmon, and coconut water.
  3. Chloride: Table salt (sodium chloride), seaweed, celery, tomatoes, lettuce, and olives.
  4. Calcium: Dairy products (milk, cheese, yogurt), fortified plant-based milk (soy milk, almond milk), leafy green vegetables (kale, spinach, broccoli), tofu, sardines, and fortified orange juice.
  5. Magnesium: Nuts and seeds (almonds, cashews, pumpkin seeds), spinach, Swiss chard, black beans, whole grains (quinoa, brown rice), avocado, and dark chocolate.
  6. Phosphate: Meat, fish, poultry, eggs, dairy products, nuts, and legumes.

It’s worth noting that electrolyte content can vary depending on the specific food source, growing conditions, and processing methods. It’s generally recommended to obtain electrolytes from a varied and balanced diet that includes a wide range of whole foods. Additionally, during periods of intense physical activity, prolonged sweating, or dehydration, electrolyte-rich sports drinks or electrolyte supplements can provide an additional source of electrolytes.
