The Role of Probiotics
Probiotics, specifically the live and active cultures found in fermented dairy products like Lifeway Lowfat Kefir, play a significant role in the maintenance of gut health and the support of the immune system.
Digestive Health
The digestive system benefits greatly from probiotics because these live microorganisms, such as Lactobacillus rhamnosus, which is commonly found in kefir, help balance the gut microbiome. By ingesting these beneficial bacteria regularly:
They promote better nutrient absorption by breaking down and digesting food more efficiently.
They can alleviate common digestive issues like bloating and constipation.
Immunity and Overall Wellbeing
Probiotics contribute to the immunity of an individual by interacting with the microbiome and the immune cells. Their presence:
Helps in the production of natural antibodies and may boost immune cells like the IgA-producing cells.
Aids in warding off harmful pathogens, thanks to the competitive exclusion of detrimental microorganisms.
In the context of Lifeway Lowfat Kefir, the probiotic cultures and prebiotics found within provide a symbiotic benefit by supporting both the digestive system and immunity, which together impact the overall health and wellbeing of the consumer.
Caring for Kefir Products
Proper handling and storage are paramount to maintain the quality and extend the shelf life of Lifeway Lowfat Kefir. Ensuring that the product remains within its optimal condition requires attention to preparation and storage techniques.
Handling and Preparation
Lifeway Lowfat Kefir should be kept refrigerated and consumed by the date on the label. Upon opening, it is important to seal it tightly after each use to preserve its balance and consistency. The serving size for an individual may vary, but typically, one cup (8 ounces) is suggested. It's imperative to use clean utensils to prevent contamination and to maintain the product's quality.
Extending Shelf Life
To maximize the shelf life of opened Kefir, keeping it at a consistent, cold temperature is key. The refrigerator should be set at or below 40°F (4°C). Avoid storing Kefir in the door shelf where the temperature fluctuates. Freezing Kefir is not recommended, as it can alter the product's texture and fizz. If the Kefir has been stored properly, it may last up to two weeks after opening, though one should always perform a quality check before consuming.
