Is It True That … An Apple A Day Keeps The Doctor Away?

Apples support immune health and gut microbiome due to their rich phytonutrients, including vitamin C and antioxidants, which aid antibody production and reduce inflammation. They are particularly beneficial for gut health, as one apple provides 100 million microbes and around 4g of fiber, fueling good bacteria that regulate immune responses. Dr. Emily Leeming emphasizes the importance of a healthy gut microbiome, as 70% of immune cells reside there. While apples are beneficial, she advises a varied diet of fruits, vegetables, whole grains, beans, nuts, and seeds to ensure a range of fibers, nutrients, and antioxidants. Reaching 30g of fiber daily is key for gut health, and dietary improvements can positively impact the microbiome within three days, enhancing immune system support.
