In the midst of a scorching heatwave, the last thing anyone wants is to turn on the oven. Cooking can feel like a chore, and our appetite often wanes in the heat. But should we change our diet to combat the effects of the sweltering temperatures? Here's an expert take on four key considerations to keep in mind when you're feeling hot and hungry.
1. Protein Intake: A Misconception
"There's no need for more protein in a heatwave," says Aisling Daly, a senior lecturer in nutrition at Oxford Brookes University. While it's true that protein-rich foods like meat, chicken, and fish require cooking, which can be off-putting in the heat, the idea that protein itself is a culprit for overheating is a misconception. The body produces more heat when digesting protein due to the energy required by the stomach, intestines, and liver to break down and absorb these complex molecules. So, that steak you crave might just bring you out in a sweat. Opt for easier-to-digest options like fruit, vegetables, and carbohydrates instead.
Dr. Daly recommends pre-cooked meats, bean salads, eggs, and Greek yogurt (even frozen) as convenient and nutritious alternatives. For a quick and balanced meal, try making a smoothie with fruit, vegetables, and yogurt, adding a dash of peanut butter for an extra protein boost. And for those who prefer their protein plant-based, lentils, nuts, milk, tofu, and cheese are excellent choices.
2. Hydration: More Than Just Water
Staying hydrated is crucial during a heatwave, but it's not just about drinking water. Dr. Daly emphasizes the importance of "eating our water," as 80-90% of fruits and vegetables are composed of water. Cucumbers, tomatoes, lettuces, celery, watermelons, and strawberries are excellent choices, with water content above 90%. Apples, carrots, cooked broccoli, pears, oranges, grapes, and pineapple also contain high percentages of water, ranging from 80% to 89%.
3. Urine Color: A Hydration Indicator
Checking the color of your urine is a simple way to gauge your hydration levels. Pale yellow urine is ideal, indicating proper hydration. If your urine takes on an orangey or dark brown hue, it's a sign of dehydration, with your kidneys holding onto water due to a lack of sufficient fluid in the body. This is a clear indication that you need to drink more water.
4. Hot Drinks: A Refreshing Choice
Contrary to popular belief, warm or room-temperature drinks can be just as effective as cold ones for cooling you down. Dr. Daly explains that your body sweats more quickly to regulate its core temperature of around 37 degrees Celsius after consuming a hot drink. Cold drinks, on the other hand, cause the body to sweat more slowly. So, enjoy your hot tea or coffee without guilt, as long as you stay within reasonable limits. While caffeine can lead to increased urine production and potential dehydration, moderate consumption (one or two coffees a day) should have minimal impact on your hydration levels.
In conclusion, during a heatwave, it's essential to listen to your body and make informed dietary choices. By incorporating protein-rich foods strategically, staying hydrated through both drinking and eating water-rich foods, monitoring urine color, and enjoying hot beverages, you can navigate the challenges of the heatwave with ease and comfort.
