• Use spices and other flavor enhancers such as spices, dried and fresh herbs, garlic and ginger, citrus, vinegars and wine. Flavors can be black pepper, cinnamon and turmeric to fresh basil, chili peppers and lemon juice.
• Use the right healthy fats from roasted nuts and avocados to olive, canola, soybean and other oils.
• Searing and sautéing foods in a pan builds flavor. Roasting brings out the natural sweetness of many vegetables and the taste of fish and chicken. If you do steam or microwave food, perk up these dishes with a finishing drizzle of flavorful oil and a squeeze of citrus.
• Get your whole grains from sources other than bread. White bread contains salt, not just for flavor but to ensure that the dough rises properly.
• Shop for raw ingredients with maximum natural flavor, thereby avoiding the need to add as much (if any) sodium.
