Prebiotics And Probiotics Science And Technology

Prebiotics and Probiotics Science and Technology is a reference book for scientists, academics and others who are simply interested in this nutritional topic. The book describes the many sources of prebiotic fiber and how the fiber benefits animal and human health. It also covers the different types of probiotic organisms and how they can be produced. Here are some of the highlights.

Sources of Prebiotic Fiber

Small amounts of prebiotic fiber can be found in raw plant foods, such as chicory root, Jerusalem artichoke and dandelion greens. Cooking the foods degrades the prebiotic content. For example, over 3% of the prebiotic fiber present in raw onions is no longer present after cooking.

The skin of the kiwi fruit is an example of prebiotic fiber found in some dietary supplements. Other supplements are derived from chicory or Jerusalem artichoke.

Not all fiber supplements are prebiotic. Most contain psyllium husk, which is accompanied by a risk of choking and abdominal obstruction.

The Prebiotic Effect

In the gut, prebiotic fiber promotes the growth of beneficial bacteria. The bacteria aid in the digestion of foods and assist with nutrient absorption. They limit the growth of harmful bacteria, such as those causing food poisoning and ulcers. So, the benefits are not actually due to the fiber, but to the increase in beneficial bacteria.

The Probiotic Effect

According to Prebiotics and Probiotics Science and Technology, the probiotic effect is exactly like the prebiotic effect, as long as the supplement or food contains the live bacteria. Adding the live bacteria to foods however is technologically challenging. The processes currently used in food manufacturing destroy bacteria.

In years past, it was thought that any bacteria in foods were undesirable. In order to manufacture a probiotic food, it has become necessary to change some manufacturing processes. There are concerns that allowing some bacteria to grow while ensuring that other types are not present is difficult, if not impossible.

Health Benefits

The health benefits listed in Prebiotics and Probiotics Science and Technology include:

• Treatment and prevention of antibiotic-associated diarrhea
• Treatment and prevention of infectious or traveler’s diarrhea
• Management of chronic gastrointestinal disease
• Reduction of allergy symptoms
• Protection against colorectal cancer
• Supporting the health of the urogenital tract
• Improved oral health

Although the supplements are beneficial for diarrhea, they promote regularity. Many people take the supplements to prevent constipation.

The book Prebiotics and Probiotics Science and Technology is available in print and electronic formats. It has received good reviews from scholars.
