Fresh vegetables have a shorter lifespan than their frozen counterparts, so you likely want to make them last as long as possible when you purchase them. Use these expert tips to help you maintain a healthy diet and maximize the lifespan of your produce.

1. Choose firm veggies. Vegetables like cucumbers, peppers, and onions should be firm, even colored, and free of bruises or other signs of damage. Be sure to pick these vegetables up in your hands and feel for consistent texture all the way around.
2. Know your leafy greens. Green vegetables like spinach, kale, and lettuce should be crisp and brightly colored, with no visible signs of wilting or rot. You can also give these leafy vegetables a good whiff before buying to make sure that they don’t smell moldy.
3. Inspect your root vegetables. The best potatoes, carrots, garlic, and other root vegetables may be a bit trickier to identify, but these simple tips can help: Look for cracking along the surface of the vegetable (an indicator that it's too dry), and be sure to avoid root veggies that smell rotten or moldy.
4. Know your farmers' market veggies. If you regularly buy your produce at a supermarket, keep in mind that these types of stores use different techniques to make veggies look perfect. While farmers' market vegetables may not look as pretty, they’re still just as tasty.
