London: Having a cup of tea with a cucumber sandwich is the ideal way to cool off in a heat wave, say scientists. According to the researchers, however tempting ice creams may be, they will not work to beat the heat. Even water should be drunk at room temperature rather than ice cold during the hottest days of the year, a newspaper reported. While the British colonial favourite of cucumber sandwiches works best during summer, the crust free, white bread versions served in posh hotels and tea rooms, do not seem to work best. Instead, having them on whole wheat bread with a slab of mayonnaise and sea salt on top works best, said food industry experts at the American Chemical Society (ACS) annual meeting. Fruit and vegetables with high water content are particularly good for hot weather, which includes cucumber but also watermelon and celery.Foods with grain are good for the body because they keep the body topped up with magnesium and calcium, preventing cramps in the heat.
