Fermented foods are yet another example of what's old becoming new again. Traditionally, almost every civilization regularly produced and consumed at least one cultured food. While our generation had all but forgotten traditional fermentation practices, now that scientific research is investigating the effect of active bacterial cultures from fermented foods on health, foods such as sauerkraut, kimchi, miso, chutneys, kefir, and yogurt are re-appearing in kitchens everywhere.
Cultured dairy products are dairy foods that have been fermented with
lactic acid bacteria, known as probiotics. There is evidence of cultured
milk products being produced as food as long ago as 10,000 B.C. While
many types of cultured milk products can be found around the world,
yogurt is by far the most common. Although the benefits of yogurt on
digestive health had already been recognized, the microbiologist Ilya
Mechnikov popularized its use throughout Europe in the 1900s, believing
that lactobacillus bacteria were responsible for the remarkable
longevity of Bulgarians.
Fermentation with lactic acid
bacteria increases the nutritive value of foods because of improved
bioavailability and can enhance the absorption of protein and minerals,
particularly calcium, iron, zinc, magnesium, phosphorus and copper.
Lactic acid bacteria can synthesize the vitamins folic acid, thiamin,
niacin, riboflavin and vitamin B12, even when they aren't provided in
Empirical research has identified a long list of health conditions that
may be helped by consuming foods containing lactic acid bacteria,
including colitis, constipation, diarrhea, gas, gastric reflux,
heartburn, Crohn's disease, gum disease and high cholesterol. Recent
studies have shown a positive effect of probiotics on autism and
Probiotic bacteria must be consumed every day to be effective as they
cannot implant in the gastrointestinal tract and they do leave the body
quite readily. Include a variety of foods fermented with lactic acid
bacteria in your diet daily.
The fermentation process increases the shelf life of dairy products. Refrigerated, yogurt has a shelf life of 35-40 days.

My name is Lisa Tsakos, Registered Holistic Nutritionist, corporate speaker and author. This blog provides professional advice from a nutrition and weight loss expert (me!) about corporate and family health. Here you'll find recipes and articles that address work-related challenges like eating on-the-go and maximizing your productivity with the right foods. You'll also find out about how you can help your children develop strong immune systems and healthy bodies. As a nutrition instructor, I often found myself thinking, "When I have kids, this is how I will feed them." With two toddlers, I have the opportunity to practice what I have been preaching and to try out my theories. So far, they seem to be working!
