The ORAC scale measures the ability of a substance to neutralize free radicals in a test tube. Foods with higher ORAC values are generally considered to have greater antioxidant capacity. However, it’s important to remember that ORAC values do not necessarily translate directly to health benefits in the human body.
7.2. Limitations of ORAC Values
ORAC values have several limitations. They do not account for how antioxidants are absorbed, metabolized, and distributed in the body. Additionally, they do not reflect the complex interactions between different antioxidants and other compounds in food. As a result, ORAC values should be used as a general guide rather than a definitive measure of antioxidant effectiveness.
7.3. How to Interpret ORAC Values in the Context of a Balanced Diet
When interpreting ORAC values, focus on incorporating a variety of antioxidant-rich foods into your diet rather than obsessing over specific numbers. A balanced diet that includes plenty of fruits, vegetables, nuts, seeds, and spices is the best way to ensure you’re getting a wide range of antioxidants and other essential nutrients.
8. Beyond Food: Other Sources of Antioxidants
While diet is the primary source of antioxidants, other lifestyle factors can also contribute to your antioxidant status. Regular exercise, adequate sleep, and stress management can all boost your body’s natural defenses against oxidative stress.
