Maintaining an optimal Omega-6 to Omega-3 ratio can help you make dietary adjustments to ensure a balanced intake of these essential fatty acids. Scientists recommend an ideal ratio of 2:1, but diets high in processed foods can push this ratio as high as 10:1, which may contribute to chronic inflammation and health issues.
