This may seem against conventional wisdom, but don't keep flour in the pantry or in a countertop container like mom did. More of us are using whole-wheat flour instead of white flour, and the wheat germ can go rancid very quickly. Once you open your bag of whole-wheat flour, transfer it to an airtight container and store in the refrigerator or freezer to help keep it fresher longer. Flour, like baking soda, can absorb odors very easily, so make sure the container really is airtight, otherwise your next batch of scones might taste like onions, garlic or leftover Chinese takeout.

On a trip, it can sometimes feel like your food options are limited to fast food joints at rest stops along the way. But it's possible to find local, sustainable and even organic food on your journey. The Eat Well Guide is an online tool that uses your two destination points -- from where you start to where you end -- and gives you healthy options where to dine on your trip. Or, if you're visiting a city and want greener cuisine options, you can just list a single address to find the closest listings. Visit EatWellGuide.org/travel_map to search your culinary journey today.

When eating out, it can be nearly impossible to find an eco-friendly option for containers in which you can bring your leftovers home, so you might think about bringing your own. The reality is, restaurants can't use your reusable containers because of health code laws, but you can: Just transfer leftovers at your table into your own reusable containers. If you forget, ask your server to package your leftovers in a single container instead of multiple ones. This will cut back on waste significantly. And if it's something like a burrito or a sandwich, ask if you can wrap it in aluminum foil only. It'll do the job, and the foil is 100 percent recyclable.
