Why Pack Your Own Healthy Snacks for Flights?

Airplane meals and airport fast food are often loaded with:

• Excess sodium (causing bloating)
• Refined sugars (leading to energy crashes)
• Unhealthy fats (digestive discomfort)

By bringing your own snacks, you:
✅ Control ingredients (avoid allergens or additives)
✅ Save money (airport food is expensive!)
✅ Stay energized (balanced nutrients prevent fatigue)

TSA-Approved Snacks: What You Can Bring

Before packing, know the TSA liquid rules:

• Solid foods (nuts, bars, fruit) = ✅ Allowed
• Liquids & gels (yogurt, hummus) = ❌ Over 3.4 oz (100ml) must go in checked baggage

Best TSA-Friendly Snacks

✔ Nuts & seeds (almonds, walnuts, pumpkin seeds)
✔ Dried fruit (apricots, mango, no-sugar-added options)
✔ Protein bars (look for low-sugar, high-fiber brands)
✔ Whole-grain crackers (pair with single-serve nut butter)
✔ Dark chocolate (70%+ cocoa for antioxidants)

Pro Tip: Pre-portion snacks in small bags to avoid overeating.
