Probiotics For Dummies Cheat Sheet

Cheat Sheet / Updated 03-27-2016

The idea that bacteria are not all bad — that good bacteria called probiotics live in your body and actually help you maintain health and even fight diseases — is one that’s just now going mainstream in the United States. You can get probiotics, along with the fiber that good bacteria eat, called prebiotics, from certain foods and from probiotic supplements.

Foods that Contain Probiotics and Prebiotics

Article / Updated 03-26-2016

Many foods contain probiotics (the good bacteria that help your body maintain health) and prebiotics (fiber that good bacteria eat but that isn’t digestible by humans). However, it’s difficult to get enough probiotics strictly through food. You need to take a probiotic supplement to get enough probiotics in your diet to maintain good health, especially if you’re treating a particular illness (such as antibiotic-associated diarrhea). Fermented foods — which used to be a larger part of the human diet because fermentation was a great way of preserving food — contain probiotics. You’ll see quite a few fermented foods on the upcoming list. Fermentation is the process of adding yeast to a food to change its structure. Primarily, sugars and starches are broken down during fermentation. One thing to keep in mind: It’s the live bacteria in the food you eat that make it full of healthy probiotics. Since heat destroys the bacteria, you need to make sure that your yogurt, for example, says live or active cultures on the label. Some yogurts are pasteurized, which kills the bacteria. Those yogurts with live cultures add them back in after the pasteurization process. Probiotic-rich foods include the following: Kefir Yogurt (with live cultures) Kimchi (a spicy fermented cabbage common in the Korean diet) Dark chocolate (a good, high-quality chocolate) Tempeh Microalgae Miso Pickles Natto (a fermented soybean) Some soft cheeses (such as Gouda) contain Lactobacilli bacteria Sourdough bread may also contain Lactobacilli Fruits such as bananas and tomatoes Vegetables like artichokes, green beans, leeks Whole-grain breads Honey

Probiotics, Prebiotics, and Synbiotics: Defining the Terms

Article / Updated 03-26-2016

The emerging importance of probiotics and their role in human health brings with it some potentially confusing terminology. This article aims to differentiate and define the most basic terms. Probiotics: The good bacteria The World Health Organization defines probiotics as “live microorganisms, which, when administered in adequate amounts, confer a health benefit on the host.” What that means is that probiotics, which can be found in food and taken as supplements, are bacteria that your body needs. Your digestive system is full of bacteria — good bacteria — that help your immune system, work to keep your digestive system healthy and efficient, and do numerous other positive things in your body. But bad bacteria, too, can get into your body, and if the bacteria balance get out of whack, probiotics add good bacteria back into your system. You’ll find probiotics in fermented foods such as yogurts (with live, active cultures), sauerkraut, and kimchi. Keep in mind that most of the time, you can’t get enough probiotics through eating foods alone, and you’ll need to take a supplement. Prebiotics: Fiber food for bacteria Prebiotics are basically food for probiotics. Taking prebiotics helps probiotics work better and more efficiently. Prebiotics not digestible by humans, but they stimulate the growth of beneficial bacteria. Common prebiotics are inulin and carbohydrate fibers called oligosaccharides. Prebiotics are found in fruits, vegetables, and whole grains. Prebiotics are an emerging field of study, and many researchers believe their potential to help you stay healthy may be as important as probiotics. Synbiotics: Combining probiotics and prebiotics A synbiotic is a supplement that contains both probiotics and prebiotics. It makes sense to make sure any supplement you take contains both pro- and prebiotics, because the two work in tandem to make sure your system has enough of the healthy, beneficial bacteria it needs. Other probiotics terminology CFUs: This stands for colony-forming unit and is the way probiotics are measured. You want to take a supplement with as many CFUs as you can find — in the 1 to 10 billion range. Genus, species, and strain: These are how bacteria are identified. The genus is the first word in a bacterium’s name; it’s the large group to which the bacteria belongs. The species is the type of individual bacteria. Some bacteria have several strains, or differentiations of the species, and this is identified by the last part of the name. Here are a couple examples: Lactobacillus rhamnosus (Lactobacillus is the genus, and rhamnosus is the species) Lactobacillus acidophilus DDS-1 (Lactobacillus is the genus, acidophilus is the species; and DDS-1 is the strain) Dysbiosis: This is the medical term for when the good and bad bacteria in your body get out of balance. Taking probiotics and prebiotics can help correct dysbiosis.
