Hold on to your beach hat! Surprising news about some warm-weather staples.
- 1.
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.
- 2.
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.
- 3.
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.
