Take a peek into my kitchen cabinet for a healthy eating tip. If you can't tell from the picture those are jars with chalkboard labels. I've been using them for almost a year now and for two good reasons: health and money.
I love nuts but find that it can be easy to eat too many at one sitting. I use the chalkboard labels to remind myself of the nutritional breakdown of the stored nut and its serving size. For instance, on my almond jar I've written 20 almonds equal 180 calories, 14g fat, 7g protein, and 6g carbs. This method has been a really great way to keep me from overindulging.
Having these jars is also an incentive to buy from the bulk aisle. Most food, especially organic, is cheaper when purchased in bulk. Plus buying in bulk cuts down on wasteful packaging, and I don't confuse things that look alike. The labels create an easy way to remember cooking ratios — if I'm storing a whole grain or beans, I write the name of the grain and the ratio of the grain to how much liquid it needs to cook.
