As women approach their 40s, their bodies undergo hormonal shifts that can bring about symptoms like weight gain, bloating, mood swings, and sluggish digestion. One of the best ways to support your body through this transition is by eating a fiber-rich diet. High-fiber foods help balance hormones, support gut health, reduce cholesterol, and keep blood sugar stable.
Scientific studies have shown that fiber plays a crucial role in hormone regulation. A 2021 study published in The Journal of Nutrition found that dietary fiber intake was associated with lower levels of estrogen, reducing the risk of hormone-related cancers such as breast cancer. Additionally, fiber supports gut microbiome diversity, which is essential for metabolizing estrogen and other hormones efficiently. Research from the American Journal of Clinical Nutrition also highlights that higher fiber consumption is linked to better insulin sensitivity, reducing the risk of type 2 diabetes and metabolic syndrome, which can become more prevalent during pre-menopause.
If you’re looking for the best foods to ease pre-menopause symptoms, we’ve got you covered! Here are the top 10 high-fiber foods that every woman over 40 should include in her diet. Plus, there’s a delicious high-fiber recipe at the end!
