Best foods to stay cool in hot weather
When temperatures climb above 30°C, the food and drink choices you make can genuinely affect how hot and uncomfortable you feel.
Here's what nutrition experts recommend eating (and avoiding) during a heatwave.
Does eating protein make you feel hotter?
Yes. As reported by BBC News, nutrition experts recommend digesting protein requires more energy from your stomach, intestines and liver than digesting other food groups, which raises your body temperature as a result.
This means a heavy, protein-dense meal like steak can leave you feeling hotter and sweatier than a lighter option would.
That doesn’t mean you should cut protein out in hot weather, but there’s no evidence you need more protein in a heatwave, your body still needs its usual amount. The trick is choosing protein sources that are lighter to digest:
- Beans, lentils and chickpeas
- Eggs
- Greek yoghurt
- Pre-cooked or cold meats
- Lighter fish such as tuna or salmon
Cold, salad-based meals built around these ingredients — rather than a hot plate of red meat — are one of the easiest ways to manage body heat through food.
Some Pure favourites that tick all the boxes are:
Why "eating your water" matters as much as drinking it
Staying hydrated in hot weather isn’t just about how much you drink. Around 80–90% of most fruit and vegetables is water, so eating water-rich produce is a meaningful part of your fluid intake.
Foods with the highest water content (above 90%) include:
- Cucumber
- Tomatoes
- Lettuce
- Melon
Slightly lower but still high (80–89% water):
- Apples
- Carrots
- Cooked broccoli
- Pears
- Oranges, grapes and pineapple
For comparison, a boiled egg is around 75% water, while a digestive biscuit is under 3%.
A salad built from high-water vegetables, paired with a lighter protein like chickpeas, feta or egg, hits both boxes at once: hydration and a full, satisfying meal, without the heat load of cooking or a heavy dinner.
Pure’s Celebrity Skin salad is built around exactly this combination — cucumber, tomatoes and lettuce — making it a practical, ready-made option on hot days.
Practical ways to eat cool this summer
- Choose cold, salad-based meals over hot, protein-heavy dinners when the temperature is high
