With a shelf-life often limited to just a few days at room temperature, strawberries are exceptionally perishable and antioxidant-rich. This means the specific storage temperatures on antioxidant capacity and aroma compounds in strawberry fruit are critical to preserving their flavor and nutritional value.

In 2010, the USDA released a list of thousands of foods ranked by their Oxygen Radical Absorbance Capacity (ORAC) score, a measure of their antioxidant potential. Understanding what is ORAC in berries, and other foods, can help you maximize your intake of health-protective compounds.

According to the USDA, the ORAC method for testing antioxidant capacity was withdrawn from official publications in 2012 due to a lack of evidence linking in-vitro results directly to in-vivo health benefits. However, the ORAC assay procedure continues to be utilized in various research fields and for commercial product comparisons.

With a reported Oxygen Radical Absorbance Capacity (ORAC) value reaching approximately 3.5 million per 100g, dragon's blood resin is often touted as one of the most potent antioxidants in the world. This article explores what the ORAC score of dragon's blood truly represents, the scientific debate surrounding this metric, and what its impressive antioxidant properties mean for human health.

According to marketing materials, One Opti Juice boasts an impressive ORAC value of 648,000 units per bottle. However, this high number warrants a closer look, as the real answer to how much ORAC value is in one Opti is more complex due to the nature of this lab-based measurement and its questionable relevance for dietary supplements.

In 2012, the United States Department of Agriculture (USDA) officially removed its ORAC database, citing that the values had no proven relevance to human health. This was a significant moment for the nutritional community, calling into question the validity of focusing on a specific daily requirement of ORAC value.

According to one study, free radicals are constantly formed in the body, making a robust antioxidant activity essential for neutralizing these potentially harmful compounds. However, the term "antioxidant activity" is often used alongside other, more specific scientific phrases.

Scientific studies show that the bioavailability of quercetin differs widely based on its source, with some forms absorbed much more efficiently than others. This makes understanding what is quercetin equivalent (QE) crucial for accurately assessing the potency and potential effects of flavonoid-rich products and foods.

According to a 2013 report by the Academy of Nutrition and Dietetics, nutrient density is a valuable concept for ranking foods and guiding dietary choices. But how do we measure nutritional value in a meaningful and comprehensive way? There are multiple methods, from simple food label comparisons to advanced scientific techniques, each providing a different perspective on a food's true worth.
