Dietitians Avery Zenker and Johanna Katz told the Real Simple portal about this. The specialists consider various types of leafy greens, including kale, spinach, arugula, Swiss chard, and romaine, to be the most valuable products. These plants contain a large amount of fiber, magnesium, folic acid, iron, calcium, and potassium. Additionally, they include essential vitamins A, B9, and K for the body. Equally important for cognitive functions are young broccoli sprouts, which possess unique properties. They contain a high concentration of sulforaphane, a biologically active compound that combats inflammatory processes. This substance also helps maintain a healthy human gut microbiome. Young sprouts are the most powerful natural source of this beneficial compound compared to mature vegetables. This factor makes them an uniquely effective option for the daily diet. At the same time, experts emphasize that regular mature broccoli also provides significant health benefits.
