There are two ways to get more good bacteria into your gut: fermented foods and dietary supplements. Fermented foods are the best source, as probioticsupplements, which are typically sold over the counter, are reserved to treat specific ailments as suggested by your doctor, and not recommended for everyday use. Plus, supplements do not have the same FDA oversight as medicationsdo.
So, a big question remains: How much probiotic food do you need? That’s not easy to answer.
There is no recommended daily intake for probiotics, so there is no way to know exactly which fermented foods or what quantity is best. Therefore, the general guideline is to just add as many fermented foods to your daily diet as possible.
Why fermented foods? Fermenting is one of the oldest techniques for food preservation. Mankind has been fermenting foods and drinks like beer and wine for centuries.
Foods that are fermented go through a process of lactofermentation in which natural bacteria feed on the sugar and starch in the food, creating lactic acid. This process creates an environment that preserves the food and promotes beneficial enzymes, B vitamins, and omega-3 fatty acids, as well as various species of good bacteria.
Another way to look at fermentation is that it takes one type of food and transforms it into another kind. For instance, cabbage becomes sauerkraut, cucumbers become pickles, soybeans turn into miso, and milk can be made into yogurt, cheeses, and sour cream.
Not all fermented foods contain probiotics. Some foods undergo steps that remove them, as with beer or wine, or make them inactive, like baking and canning. However, most fermented foods contain some amounts of the good bacteria.
If there is a potential downside to fermented foods, it is that their taste and smell can be quite strong, which may be unpleasant for some people. The unique flavors and textures of fermented foods are due in part to the different species of bacteria used.
On the upside, there are many types of fermented foods from which to choose, so there is a good chance you can find something you will enjoy.
