If you're still hanging on to that jar of paprika you bought in 1985, it's time to refresh your spice rack. Most spices have a shelf life of about 2 years before their aroma, flavor and health benefits are compromised. And fresh ground spices not only add lots of exciting flavor to food, they have also been shown to be potent anti-inflammatory agents. Since inflammation is thought to be at the root of many chronic diseases, like rheumatoid arthritis and heart disease, keeping your spice rack up to date could be a real boon to your health. Bonus: Since boredom is one of the biggest reasons people fall off a healthy diet, using full-flavored spices could help you stick to your weight-loss plan. So replace old jars with fresh ones, get small containers so you can replenish often, and consider keeping them on risers in your cupboard or in a rack so they are easy to see and use.
