By understanding the gut-brain connection, you’ll see why small dietary shifts, like reducing sugar and embracing whole foods, can significantly improve how you think and feel. This insight offers a practical, science-backed path to regaining mental clarity and emotional balance. Read along with the original article(s) here: https://drjennybrockis.com/2017/8/21/lost-your-edge-could-it-be-something-you-ate/ Quotes to ponder: "New data from the Whitehall 11 Study has shown that eating a diet high in processed sugars is linked to an increased risk in developing anxiety or depression." "While eating a small amount of sugar can make us feel better initially, over the longer time it elevates levels of inflammation, which is bad for our body and brain." "If you’re serious about looking after your cognitive and mental health, it’s time to stop the excuses and take the steps to reduce sugar and trans fats consumption and increase healthier options."
