Probiotics are good microorganisms, usually good bacteria, that are similar to the helpful bacteria found in the human intestinal tract. These live active bacteria help regulate digestion and improve the health of the person who ingests them. These microorganisms can be found in fermented foods such as sauerkraut, or in fermented dairy products including yogurt, buttermilk, and kefir. It is recommended that people who have been on antibiotics or who have digestive upset should take in some form of probiotics from either food or supplements to help replenish their own natural bacteria.
Yogurt is probably the most commonly eaten probiotic food. It provides calcium to help build strong bones which prevents osteoporosis. Yogurt can also help strengthen the immune system and prevent vaginal yeast infections in women. Studies also show that low fat yogurt may lower LDL “bad” cholesterol and raise HDL “good” cholesterol. It also provides protein that can help fill you up. Greek yogurt is especially good for this. It has twice the amount of protein than regular yogurt. When buying any type of yogurt, choose one that is low in fat, low in sugar and contains live active cultures.
Kefir is another commonly known probiotic drink. It is a milk drink that Kefir grains have been added and then fermented. Kefir is usually used in a smoothie with added ingredients, such as sugar, since the plain Kefir is often very sour. Its probiotic effect is similar to that of yogurt, helping to reduce cholesterol (especially if it contains plant stanols) and may also help reduce blood pressure. However, kefir contains different live active cultures than yogurt and may have a better probiotic effect than yogurt. Eating a variety of low fat dairy products will help ensure you get all the health benefits of these different foods.
Healthy Action Step: For a different take on a breakfast smoothie, place plain Kefir in a blender and add buckwheat honey to taste with a handful of your favorite fruit. Blend and enjoy!
