Drink plenty of water. Combat the dehydration of air and road travel, which can leave you feeling tired, cranky, and vulnerable to snack attacks. By drinking at least eight 8-ounce glasses of water every day, you'll have the energy to take in the sights. Hot climates can be especially dehydrating, so you'll need to drink even more. If the water quality is questionable, purify or boil it, if possible, or drink bottled water.
Vacation is a great time to have fun.
But don't leave your healthy eating habits at home. Aim to eat five servings of fruits and vegetables every day. Choose whole-grain breads and nonfat foods when you can. She is a co-author of The Nutrition Desk Reference. All rights reserved.
