Surprising news about some warm-weather staples.
Lemonade
It may prevent kidney stones. In a long-term study, Duke University doctors found that people who drank a daily mix of lemon juice and water had increased levels of urinary citrate (low levels are linked to stones). Avoid sugary, calorie-laden mixes and stick to ’ades made with real lemon juice.
Air conditioning
It may make us fat. Before AC, we had to expend energy (and burn calories) to regulate body temperature; now it’s done for us. So turn off the air once in a while, open the windows and let your body do its job.
Watermelon
Don’t store uncut melon in the fridge: It may be healthier at room temperature. Why? Cancer-fighting carotenoids still develop after a melon is picked, but cold temps seem to slow the process.
