PROBIOTIC
FOOD
Probiotic
food is that containing bacteria or yeasts that can be beneficial for health.
Yoghurt is
not probiotic because the bacteria it contains (Streptococcus thermophilus and Lactobacillus
bulgaricus)
is already dead when it reaches the intestinal tract. However, other dairy products containing Bifidobacterium bifidum or the Lactobacillus casei are probiotic.
In addition, fermented non-dairy products such as miso or tempeh can have
a probiotic effect.
Yoghurt has in common with probiotic
food that the bacteria that
transforms the milk generates lactic acid. The
acidity helps prevent harmful bacteria proliferate in the intestines.
Other benefits attributed to probiotic food are the strengthening
of the inmune system, the prevention
of colon cancer or a reduction
in the cholesterol levels, though there is little information about such effects. From
another side, some effects are
related only to certain probiotic microbes.
