Fermented foods like sauerkraut, kimchi, and kefir are gaining popularity, but do they really improve health? Thirteen years ago, Donna Schwenk, while pregnant with her third child, developed preeclampsia, leading to an emergency delivery. Her baby, Holli, was born prematurely, and Donna faced diabetes, high blood pressure, and extreme fatigue. In search of a remedy, she discovered kefir, a fermented milk high in beneficial bacteria, in a health food store. Adding it to Holli’s bottles, she saw her baby gain four pounds in a month. Consuming kefir herself led to her own health improvements within 12 weeks.
Convinced of the benefits, Schwenk wrote a book on how fermented foods, rich in bacteria, can positively impact gut health, immunity, weight, metabolism, and mood. She joined a PBS special, exploring current research on fermented foods like kefir and yogurt. Fermented foods have been identified as a major emerging food trend.
Michael Pollan, a proponent of healthy eating, has embraced home fermentation, and LA nutritionist Kimberly Snyder advises her clients to eat fermented vegetables daily for better weight management, skin, and energy levels. Research increasingly emphasizes the gut’s crucial role in health. Nutritionist Kathie Swift, who addresses various health issues, always begins with gut health, as it affects digestion and vitamin absorption. Studies even show changes in gut bacteria can impact weight and mood.
The balance of good and bad bacteria in the gut is crucial. Daniel O’Shaughnessy, a nutritional therapist, warns against bad bacteria thriving on sugar and refined carbs, leading to issues like chronic fatigue and food intolerances. Rather than relying on sugary drinks with transient bacteria, a diverse intake of fermented foods offers a variety of beneficial strains.
While fermentation has historical roots worldwide, it remains vital today for nutritional reasons. Fermented foods like Korea’s kimchi, Germany’s sauerkraut, and Japan’s miso are staples that promote long life. However, moderation is key—excess can upset the stomach. Start slow, introducing small amounts, and aim for a varied diet featuring different fermented foods.
Look for products with live cultures and try DIY fermentation at home using simple ingredients. Pair fermented foods with prebiotics like onions and garlic to support gut bacteria growth and limit sugar intake to reduce bad bacterial growth.
With options like homemade kefir, miso soups, and coconut yogurt, fermented foods offer diverse ways to enhance gut health. While making your own may seem daunting, the benefits of these nutrient-rich foods are worth exploring.
