To replace the water that we lose when we sweat, Registered Dietitian /*Rebecca Scritchfield*/ recommends stocking up on fruits and veggies, which are almost all water, and quite nutritious.
"Some of the nutrients that you get in dairy foods, you can actually get in vegetables. For example, some of our leafy greens are a good source of calcium," Dr. Scritchfield said.
Fill your cart with alternative sources of fat instead of processed or, especially, fried foods.
They're so hot, so hard to digest, with all that extra fat in there," said Dr. Scritchfield. "Your best sources of fat in this heat are going to be from seeds and nuts and avocados."
And most people know to stay hydrated, but check the labels on flavored waters and other drinks.
"A lot of waters are kind of "fancified" and they've got artificial colors and flavors, some can have more than a day's worth of sugar in just one bottle," said Dr. Scritchfield.
Be sure to check the caffeine content of drinks as well.
