Taking a cue from queuine
Let me introduce you to queuine, a little-known vitamin-like micronutrient that your body cannot produce. (You can acquire it from certain foods, and it is produced by specific bacteria in your gut.) You can think of it as an essential nutrient that fine-tunes how your body reads your genes, switching them on or off to create needed proteins that control a slew of vital functions. It's essential for brain health, memory, control of your stress response, and defense against cancers.
Studies indicate that making sure you get enough queuine (pronounced "cue-o-scene") through foods and taking steps to have a healthy gut biome lets this little-known powerhouse do its best work. The sources containing the most queuine are wheat germ, coconut water, tomatoes, whole and skim cow's milk, and, to a lesser degree, but still important, fermented food, like kimchi, yogurt and kefir. When combined with a diet loaded with fiber-rich foods like whole fruits, vegetables and 100% whole grains that support overall gut health, you are making sure you are getting the nutrition you need to stay healthy longer and function at an optimal anti-aging level.
