Human bodies are essentially ecosystems.
Microbes live on and in us. On skin and within intestines (among other places). We have a symbiotic relationship with many different types of bacteria. They are a vital component to health and conversely can be a cause of disease.
Certain strains of bacteria protect us from pathogenic (bad) bacteria. The “good” bacteria inhibit the “bad” through competition.
Intestinal bacteria determine how our immune system responds. For example, A higher composition of intestinal bifidobacterium is correlated with a decrease in allergies in infants. Healthy, non-allergic infants have more bifidus bacteria.
People suffering from Crohn disease or Ulcerative colitis have lower levels of bifidobacterium and lactobacilli. When bifidobacteria is supplied through supplementation, studies indicate that symptoms go away; but when supplementation stops, symptoms return. There is something that is not allowing UC or Crohn disease patient’s bifidobacterium to grow and colonize the intestines naturally.
Most disease conditions have a lower level of bifidobacterium. Normal microflora is necessary to the development of the immune system.
Extreme hygiene can reduce natural microflora, increasing the prevalence of allergies particularly in children. Make sure your probiotic foods or nutritional supplement diet contains both Lactobacilli acidophilus and Bifidobacterium.
