Loving your bacteria
When my kids were little, I used to joke that bacteria are our friends, so I didn’t worry much when their pacifiers fell on the ground. As an infectious diseases specialist I had also seen the harmful effects of using too many antibiotics – emergence of bad bacteria like MRSA (methicillin resistant Staphylococcus aureus) and development of diseases due to killing off of good bacteria (like Clostridium difficile colitis, a serious inflammation of the gut caused by antibiotics). So I also tried to avoid giving them antibiotics. New research suggests that bacteria may be more helpful than we ever knew.
Think before you eat
We may be eating in unhealthy ways without realizing it. Even healthy foods can lead to problems in certain people – for example dairy products in people who are allergic to them or wheat in people who have celiac disease. But even if food does not cause a bad reaction in us, there is research evidence that we are not in as much control of what we are eating as we think we are.
The first problem is that we often eat without thinking. Dr. Brian Wansink at Cornell University has done some fascinating experiments (which he writes about in his book, Mindless Eating) that look at why we eat more than we think. In one experiment he had people eat bowls of soup while he watched them using hidden cameras. For some people, more soup was piped into the bowl (without them knowing it) as they were eating – it was a bottomless bowl. These people ate more soup than those who had a regular bowl. Similarly, he has shown in experiments that people will eat less food if they use a smaller plate. In yet another experiment, he went to a movie theatre where a first-run movie was playing just after lunch on a Saturday. He prepared popcorn in advance and made sure it was really stale but still safe to eat. He offered each person who bought a ticket a free soft drink and a bucket of popcorn (some buckets were medium in size and some were large but all were too big to finish). People who got the large containers, ate more popcorn (even though it was stale). He surveyed people when they were leaving the theatre and most people who had the large buckets said that they would not be fooled into eating more popcorn by a larger bucket.
Does food cause inflammation?
I am fascinated by food – what makes us eat the food we eat and how it affects our health. I’m especially interested when there is evidence to support the ideas.
As the American diet has changed in the past few decades, we have been gaining weight. It is also true that we are seeing more diseases – especially those that have an inflammatory component. Inflammation is when the body responds to things that shouldn’t be there – like an infection or a chemical – and the body sends cells to the area to fight them off. This can lead to pain and swelling, among other things. Some diseases caused by inflammation have “itis” at the end – arthritis, colitis, bronchitis, etc.
Is it possible that the food we eat is causing some of these diseases that are due to inflammation?
