Secret Superfoods You Walk Past Every Time You Go Shopping

15. Brazil Nuts – The Selenium Superstars

One Brazil nut a day can help meet your daily selenium needs, a mineral crucial for thyroid function, immune health, and cognitive support. Brazil nuts are also rich in healthy fats, magnesium, and antioxidants, which help reduce inflammation and promote heart health. Because they’re so nutrient-dense, you only need a couple per day to reap their benefits. Enjoy them as a snack, in smoothies, or blended into homemade nut butter for a delicious and powerful nutritional boost.

16. Kefir – The Probiotic Powerhouse

Move over, yogurt—kefir is here to level up your gut health! This fermented dairy drink contains up to 61 strains of probiotics, making it one of the best foods for gut microbiome diversity. It’s also rich in calcium, vitamin D, and protein, supporting bone health and immune function. Thanks to its fermentation process, kefir is often easier to digest than milk, making it a great option for those who are lactose-sensitive. Use kefir as a base for smoothies, salad dressings, or even in overnight oats for a tangy and gut-friendly twist.
