Recent news of the unprecedented and massive outbreak of E. coli in Europe has public health officials scrambling to find the source of contamination. This toxic, antibiotic-resistant version of E. coli bacterium is like no other American scientists have seen. Since its discovery, this super bug has killed at least 22 and sickened over 2,330 people in 12 European countries.
Escherichia coli, or E. coli is a natural inhabitant of the human gut, but it is no stranger to food contamination and has caused many outbreaks across the globe. Although some strains are harmless, when an infection is present E. coli causes digestive symptoms similar to typical food poisoning such as diarrhea, cramps, gas and bloating. However the new German, toxic E. coli strain or enterohaemorrhagic E.coli (EHEC), causes much more serious issues such as bloody diarrhea and even seizures, strokes and comas caused by the bacteria attacking the kidneys.
While investigators struggle to identify the initial source of E. coli contamination, everything from unclean cucumbers, tomatoes and sprouts have been blamed. Still the real cause of this extraordinary outbreak is a mystery and has left many people afraid to eat fresh produce. A healthy amount of caution is wise, but avoiding vegetables hardly seems like a good strategy.
The fact is all of us have an eco-system of bacteria, good, bad and neutral, teaming within our digestive systems. This delicate balance of trillions of bacteria has the power to either keep us healthy or make us sick. Maintaining proper balance of good bacteria helps crowd out potentially bad bacteria and also supports good digestion. With over 1,000 strains of beneficial bacteria can be found in the human gut, it makes sense to choose a probiotic supplement that reflects this natural diversity. A probiotic supplement with the right amount of cultures and strains can help promote digestive health, bowel regularity and strengthen the body’s natural immune defenses.
Although infection with this super-strain of E. coli bacteria has been very limited in the US, the CDC recommends proper hand washing and food preparation techniques to keep food-borne infections at a minimum. Common sense would also suggest that maintaining your own personal “gut ecology” might also be a good idea. Research shows that probiotic supplements might be a smart way to tip the balance of bacteria in the digestive system in favor of good bacteria.
Did you ever think that what goes on in your gut could affect your heart? It may seem far-fetched, but it’s not. Think about it: the intestinal lining is connected to the bloodstream, which acts as a direct communication line with the heart and the rest of the body.
Recent studies have found an interesting gut-heart connection. When gut bacteria break down phosphatidyl choline from lecithin, a common dietary ingredient found in foods like eggs, dairy, meat, fish and soy, a metabolite called trimethylamine N-oxide (TMAO) is formed. TMAO promotes atherosclerosis, and higher amounts of this metabolite in the blood increase the risk of heart disease.
This is an interesting study, but there are many questions that still need to be answered. Which bacteria are more likely to produce this TMAO? How does modifying gut bacteria change the heart disease risk? More studies are needed to determine this, but researchers suggest that probiotics may be used in the future for preventing heart disease.
It’s exciting science, though still in the early stages. But the overall message is clear: what happens in your gut affects the rest of your body. No question!
