An Avocado a Day…
As you may already know, lemons are a great way to keep your food fresh. I can still clearly remember my mom squeezing lemons on my cut-up apples before putting them in my brown paper bag lunch. But did you know that lemon juice can be used to keep other foods, such as avocados, from browning?

If your snack has left you too full to finish a whole avocado, squeeze some lemon juice on the avocado before putting it back in the fridge. Avocados are full of ascorbic acid, so when exposed to oxygen, the fruit turns brown pretty quickly. However, the citric acid keeps the ascorbic acid at bay, meaning that your avocado is edible for at least another day!
