Cold hydrating foods for summer recipes
What are some cold hydrating foods for the summer? Before we list recipes of foods that hydrate, it’s important to examine hydration and dehydration in some detail.
Dehydration
In the summer, we tend to sweat more due to the combination of hot weather and increased physical activity. When we sweat, we not only lose fluids but we also lose important substances called electrolytes. So there’s more to it than just drinking water alone, especially when we sweat a great deal. But what exactly are electrolytes, and why do they matter?
What are electrolytes?
Electrolytes are minerals such as sodium, potassium, chloride, calcium and magnesium. Some minerals have positive electrical charges, while others carry negative ones. These electrical charges dissolved in fluid help regulate fluid balance, nerve impulses, muscle contractions and maintain proper pH levels in our blood. Our heart, kidneys, and brains cannot work without these functions.
Discover more about electrolytes.
The side effects of dehydration
Not drinking enough water can lead to various complications, even if the dehydration is mild.
You may experience headaches, dizziness, and difficulties with memory, concentration and digestion.

It can also affect your mood. In addition, not staying properly hydrated puts us at risk of developing heat stroke, kidney stones, urinary tract infections, and constipation.
Therefore, to keep our body working well during the summer, it’s important to replenish electrolytes and fluids. You can easily do so by turning to cold hydrating foods for the summer, which we will address a little later in the post.
Learn more about the importance of drinking water.
Are sports drinks good for hydration?
Many of us know sports drinks contain electrolytes, but they also usually contain sugar. That’s because sports drinks are designed for athletes and the sugar serves a specific purpose. The sugar in sports drinks replenishes the sugar that athletes deplete from their blood during intense, prolonged exercise, providing the necessary fuel for them to keep going strong.
When not performing intense, prolonged activity, sports drinks may not be appropriate for the average person because they can contribute “free” sugars to our diet. “Free” sugars are natural sugars removed from their original food and added to other foods as a sweetener or preservative. This includes sugars naturally present in honey, syrups, fruit juices and fruit juice concentrates.
“Free” sugars differ from “intrinsic” sugars in whole fresh fruits, vegetables, dairy and grains. Unlike “free” sugar, “intrinsic” sugar comes packaged with other nutrients like fibre, fat, and protein, which causes it to be digested more slowly, taking longer to enter the bloodstream. The more time it takes sugar to enter the blood, the slower blood sugars rise, preventing unhealthy glucose spikes and unpleasant energy crashes.
“Free” sugars guidelines
To reduce risk of metabolic diseases, recommendations are to not exceed 50 grams of “free” sugars a day.
As an example, a 20-ounce (591-ml) bottle of Gatorade contains 34 grams of “free” sugar. This doesn’t leave much room for other “free” sugars we may eat the rest of the day. There are sugar-free sports drinks, but perhaps you’re trying to avoid artificial sweeteners and looking for a way to hydrate that comes with the bonus of promoting health and energy and decreasing inflammation.
Can you eat hydrating foods instead?
A great alternative to hydrating with plain water and sports drinks is hydrating through nutrient-dense foods and beverages. These foods contain fluids and electrolytes. In addition, their “intrinsic” sugars come packaged with healthy fats, proteins, fibre, and several beneficial vitamins and antioxidants.
So as the scorching sun embraces us during the warmer season, let’s keep our bodies cool, hydrated and nourished. What better way to do so than eating some delicious, cold hydrating foods for the summer.
