Once you have been taking Lactobacillus acidophilus (L. acidophilus) through food items containing living L. acidophilus or using L. acidophilus supplements, the bacteria should begin to implant themselves into your intestines. Once these bacteria have arrived in your digestive system, and are established, it is important to ensure they grow and multiply in the colon. To ensure the L. acidophilus living in your colon will thrive, you must ensure it gets the nutrients this bacteria requires to proliferate.
One main macro-nutrient L. acidophilus requires to survive is sugar. L. acidophilus metabolizes sugar to stay alive; therefore, sugar is a food L. acidophilus will benefit from.
To get the essential sugars to the L. acidophilus in the colon, sugars which are not completely digested by the digestive system must be ingested. One sugar that reaches the colon in large quantities is lactose, the sugar found in milk. Lactose is an important carbohydrate for L. acidophilus, and should be ingested regularly to ensure the bacteria in your digestive system has the food it needs to proliferate.
In addition to requiring sugars to metabolize, L. acidophilus also needs to be provided with amino acids, vitamins, minerals, and fatty acids. One comestible that contains the macro and micronutrients that L. acidophilus needs is sweet dairy whey. The pH of whey is approximately 6.0; which makes it slightly acidic. Because whey is slightly acidic, it can help make the digestive system less conducive to the growth of harmful pathogens that prefer a more alkaline environment. Sweet edible-grade whey is comprised of approximately 60 percent lactose, 12 percent lactalbumin, and 11 percent minerals. Whey also contains anywhere from around 1 to 4 percent butter fat as well.
If you do not already know, whey is a byproduct of cheese making procedures. Most of the butter fat and casein protein in milk will become cheese; therefore, whey does not have very high amounts of casein protein or butter fat.
Research indicates that the growth of L. acidophilus in the colon can be encouraged by simply ingesting lactose. In one study, conducted by the Food and Drug Administration (FDA), doses of 240 grams to 400 grams of lactose was shown to be effective at promoting L. acidophilus colonization of the colon.
The Benefits of Whey Protein
The amino acids in whey protein are readily assimilated by the body; whey amino acids have a bioavailability of 98%. Research has shown that whey protein is superior to many other types of protein in regards to the quality and bioavailability. The soluble protein lactoglobulins that are in whey, are the same as those present in serum globulin in human blood. The primary soluble proteins in whey are beta-lactoglobulin, immunoglobulin, alpha-lactalbumin, and serum albumin.
Whey protein powders, that have been processed in ways that do not denature the amino acids naturally present in whey, can enhance the immune system's function. Whey protein powders provide amino acid precursors to the critical antioxidant glutathione—which is used in several ways by the body. Glutathione is important for lymphocyte function, is an antioxidant, and is a detoxifying agent at the cellular level.
Many whey protein powders do not contain any lactose, and therefore will not do a very good job of bolstering L. acidophilus that is present in the digestive system. Sweet edible-grade whey should therefore be mixed with whey protein isolates and ingested so the body can get the benefit of both.
Although a high protein diet is not good for individuals suffering from a kidney disorder of some kind, there is much scientific evidence that a high protein diet is not able to hurt individuals with healthy kidneys.
