Carrots and blueberries - superfoods you cannot ruin by grinding, blending and even the falsely depreciated use of the microwave oven. Cooking / Food-Processing Done Right: 5 Things to Remember to Make the Most of the Antioxidant Prowess of Your Foods Cooking or the preparation of food (food processing at home) is something I would love to address more often. Unfortunately, studies such as Boyan­ Gao's recently published paper in "Food Science & Nutrition" are truly rare. In said paper, the Chinese scientists followed up on recent studies that indicate that different food preparation methods could significantly change the chemical profiles and bioactivities including the antioxidant and real-world anti-inflammatory activity of (super-)foods.
