10 Healthy Foods That Cost Under $1

Oatmeal (about $4 per 42-ounce can or $0.18 per ½-cup dry serving)

This unassuming breakfast option contains soluble fiber, which may help lower cholesterol and consequently the risk of heart disease. For a quick breakfast, Stadler recommends making overnight oatmeal: “Cover ½ cup oats with 1 percent milk or soymilk and place in the fridge. In the morning, top with your choice of grated apple, berries, dried fruit, slivered almonds, walnuts, or ground flaxseed and drizzle with 1 teaspoon honey.”
