A staple in Japanese cuisine, miso is rich in the "good" bacteria lactobacillus acidophilus. But f you want the highest probiotic content out there, the prepackaged packets of soup from the grocery store just won't do.
What to look for: Look for unpasteurized miso that has the "live" cultures you want in your diet, since unpastuerized miso doesn't offer all the same healthy benefits. Miso Master is a line of fresh, unpasteurized products that you can order online or find at your health food store. Use it to season your favorite veggies, blend into a salad dressing, or warm up with a cup of homemade miso soup at home.
