Tula’s Founder Shares Her Must-Have Products, Gut Health Tips, and More

Dr. Raj always travels with a bag of raw and unseasoned almonds, like the Blue Diamond Whole Natural Almonds ($13). "With long flights and jet lag, I tend to get hungry at weird times, and it's not easy to find healthy options in airports or hotels. A handful of almonds does the trick of tiding me over until I figure out my next proper meal," she says. It's a portable snack that can fit in your purse or carry-on pocket. She also recommends walnuts or peanuts if you're not a fan of almonds. "They're a great source of protein and satisfying. They make you feel full, so it's a great alternative to an unhealthy snack."

Pro Tip: Dr. Raj's biggest travel tip is to make sure you are consuming enough fiber. These foods help regulate your system.
