(HealthDay)—With so much emphasis on fresh, farm-to-table foods, it's easy to overlook the value of canned items. These are convenient, often cheaper alternatives to fresh and frozen.

Use these tips to help you choose wisely.

When shopping, look for cans in good shape. Don't buy—or keep—cans that are dented, rusted or swollen. Cans have a packing code for tracking them through interstate commerce, but these numbers have nothing to do with their freshness. Look for a "best if used by" date for peak quality.

Canned foods are safe indefinitely as long as they're not exposed to either freezing temperatures or temperatures above 90 degrees. But foods with high acidity, like tomatoes and fruits, taste best if eaten within 12 to 18 months.

Now for the cautions.

Watch the salt. Salt, or , is often used as a preservative, but you can shop for low- or reduced-sodium or no-salt-added varieties. Compare the sodium content of different brands on their and choose foods with the lowest amount. You can also drain and rinse canned to reduce .

Watch the sugar. Again, read the ingredients list and avoid foods with added sugar. Compare the sugar content of different brands on the nutrition labels and choose foods with the lowest amount. When buying canned fruit, look for products that are canned in water or its own juice. If you have no choice, drain and rinse any foods packed in syrup.
