Home-brewed tea is a good source of catechins, a type of antioxidant that benefits the heart by helping blood vessels relax. That’s especially helpful for people with rheumatoid arthritis, who are at increased risk of heart disease. Bottled teas don’t have catechins, which degrade in a few days. Drink home-brewed instead and save about 50 cents per 8-ounce serving.

A good source of protein, beans are practically fat-free and packed with fiber, which helps reduce inflammation as well as LDL (the “bad” cholesterol). Swap beans for half the ground beef in burritos, burgers or casseroles. You’ll save more than $2 per 4-ounce serving (and slash fat, too).

Plain oatmeal is loaded with heart-healthy, fill-you-up fiber. Because it’s also low in fat and calories, it can help you lose weight to take pressure off your joints. Compared with ready-made granola, oatmeal will save you about 15 cents per half-cup serving.

Studies show that most frozen produce is just as nutritious as fresh – and it keeps a lot longer. You could save about 45 cents per ²/³ cup by buying frozen green beans instead of fresh. 

Canned salmon is a great source of lean protein and omega-3 fatty acids, which help fight inflammation and may even boost mental function. The American Heart Association recommends eating two fish servings per week. Lunch counts, so stuff a pita with salmon salad instead of deli meat to save as much as 30 cents per 2-ounce serving.
