Though probiotic supplements contain significantly higher amounts of particular strains of bacteria than food, you can get your fair share of probiotics from certain food sources too. In fact, most large studies and meta-analyses do not seem to support the idea that supplements are better than foods that contain probiotics. "Eating foods such as yogurt and sauerkraut should be enough for otherwise healthy people," says Garden.

First thing first: Eat more sour foods. Sour foods might not sound like the most mouth-watering meal addition, but hear us out. Fermented eats, like sauerkraut, kimchi, pickles and kombucha, all contain some probiotics. Apple cider vinegar is another great source of probiotics. You can incorporate it easily in everything from your salad dressings to dips and even soups. Certain dairy products, like yogurt (especially kinds derived from goat's milk) and kefir, and certain types of cheeses, including gouda, mozzarella, cottage cheese and cheddar, contain probiotics.

Another benefit to filling your plate with probiotics? You won't have to remember to take yet another daily supplement.
