Foods to Avoid During Heatwaves: Nutritionists Reveal Surprising Blacklist

As heatwaves intensify, experts are warning against consuming certain foods that, despite seeming like cooling choices, can actually exacerbate the body's struggle against high temperatures. The human body works overtime during heatwaves, employing mechanisms like increased sweating and heart rate to maintain a stable internal temperature, a process that consumes significant energy and fluids.

Nutritionists highlight that the "thermic effect of food" means digestion generates heat, and some foods produce more than others. Heavy, fatty meals, including fried foods and red meat, require prolonged digestion, leading to excess internal heat. Similarly, highly salty snacks like chips and cured meats disrupt fluid balance, forcing the body to retain water and hindering its ability to cool through sweat, thus accelerating dehydration.

Consuming the wrong food during a heatwave is, figuratively speaking, like adding logs to a fire that is already burning too strongly.

Even seemingly refreshing treats like ice cream can be deceptive. According to nutritionist Lola Biggs, the high fat and sugar content in ice cream demands significant digestive effort, ultimately raising body temperature. The same applies to cakes, pastries, and sugary drinks, which cause metabolic spikes and require water for processing, further contributing to dehydration and a feeling of increased heat. Even alcoholic beverages like beer and wine are identified as detrimental to hydration and temperature regulation during heatwaves.

Ice cream is rich in fats and sugars, which causes the body to invest significant effort in digesting it, and this process ultimately raises body temperature.
