KIMCHI & FERMENTED FOODS AND DRINKS
Whether you eat them (Sauerkraut; Kimchi) or drink them (Kefir, Kombucha): Fermented foods have a lot more to offer than the fact that you can practically keep them in the fridge forever.
The probiotic bacteria they contain help the balance in your digestive system, helping your stomach get the most nutrients and vitamins from all of the other foods you eat. As an athlete, you’ll be able to digest the ridiculous amounts of food you sometimes eat, without having to compromise on the nutrient absorption. (This also means less supplements.)
