You've Got the Power: Choose Wisely for A Healthy GI

When I arrived early this morning in the press room for Digestive Disease Week 2007 (DDW), I claimed my spot at one of the long tables alongside journalists from all over the world (ah, brings back memories of my former life as a newspaper reporter), set up my laptop and made my way to the coffee station.
I was pleasantly surpised when I spotted a breakfast buffet of scrambled eggs, bacon, potatoes, fresh fruit, danish, crossiants and a variety of cereal. After arranging a colorful plate of melon and berries I came to a (plastic) fork in the road. Lemon-filled danish or raisin bran? Well, I did what any gastro-logical girl would do and confidently and unapologetically placed a lemon-filled danish next to my fresh fruit. Good choice? Of course not! But I take full responsibity for my irregularity today. See, it's past 3 p.m. and nothing's moving yet.

Guess, I should've gone for the raisin bran.

So what's the point you ask?

Well, I had the good fortune of attending an insightful press conference yesterday where gastro experts presented research that all stressed the same conclusion: that lifestyle choices when it comes to things like diet, for instance, have a huge impact on our overall gastrointestinal health.

While we can't choose our genetic make-up or whether it rains on our parade, we can make certain lifestyle choices like choosing what we eat your or ordering an appetizer for dinner. And you know what is so key: these choices, while they may seem small may have a significant impact on our gastrointestinal (GI) system, and affect our risk for certain diseases,our weight and our general GI-related activity, which is basically everything that happens from our mouth, down our espophagus, inside our stomach, throught our intestines and out.

“Many factors come into play when managing a healthy lifestyle. While some factors may be difficult for patients to change, other simple adjustments, such as adopting a vegetarian diet early in life or ordering the appropriate soup while eating out, may result in decreased risk for obesity and colon cancer," said Alan Buchman, M.D., MSPH, AGAF, Feinberg School of Medicine of Northwestern University School of Medicine. “The studies presented today further demonstrate how researchers are beginning to understand the links between digestive diseases and lifestyle – most notably, diet.”

You go Dr. Buchman! I'm forever grateful for your statement!

See,these findings are so important and I finally feel vindicated for what some may call "my annoying pronouncements" about the importance of our digestive health in relation to our overall health and well-being. In fact, much of what has been discussed at this conference showcases the relationships between digestive health (digestive diseases) and other health conditions/diseases such as cancer, diabetes, obesity, heart disease, asthma, reproductive health, nutritional deficiances, and mental health.

By the way, my gastro-friend and co-worker Jennifer Randall scribes her daily choices in her blog, "Jennifer Randall is Having her Cake and eating It Too" Check it out for inspiration!

Here's a summary of what was presented and what you need to know:

Life Long Vegetarian Diet Reduces the Risk of Colorectal Cancer

In case you weren't aware: The average person’s lifetime risk of developing colorectal cancer (CRC) is about seven percent. The role of diet in preventing colorectal cancer is still under debate. Most of all, previous studies foucused on middle-aged people, which suggested that colorectal cancer development could start before common interventions.

These facts prompted sesearchers from Tata Memorial Hospital (TMH) in Mumbai, India, to determine whether a vegetarian diet helps reduce the risk of colorectal cancer if started very early in life.

In this study, researchers used a prospectively created database of 8,877 Indian patients managed in a clinical nutrition service from January 1, 2000 through December 31, 2005, to examine the association of life-long vegetarianism with incidence of CRC. During the evaluation for nutrition support, a history of life-long vegetarianism (due to religious reasons) was obtained from all patients to plan an appropriate diet. Twenty-seven percent of subjects (2,092 patients) from the control cohort were life-long vegetarians and 22.4 percent (178 patients) of subjects with colon cancer were vegetarians.

Bottom line:
“A well-planned vegetarian diet is a healthy way to meet your nutritional needs,” said Yogesh M. Shastri, M.D., of Johann Wolfgang Goethe University Hospital, Frankfurt, Germany and previously a co-author of this study at TMH, Mumbai, India. “The exact mechanism by which life long vegetarianism may reduce the risk of sporadic CRC needs further investigation. Prolonged vegetarianism starting in early life may be a viable lifestyle option for those at risk of developing the disease.”

Dinner plans? Have a "Fatty Soup" as an Appetizer And You'll Eat Less


Many people believe that ordering an appetizer can actually make you hungrier and that you tend to eat more of your entrée as a result. But, researchers from the University of Texas Medical Branch in Galveston, Texas, feel that what you order as a starter determines your overall appetite, as absorption of fat in the small intestine induces the feeling of being full and slows down gastric emptying. The aim of this study was to investigate whether a fatty soup consumed before a meal might reduce food intake in both lean and obese subjects and whether this possible inhibitory effect would be related to changes in gastric functions.

Here's what they did:

For the study, investigators recruited 12 lean and 12 obese healthy subjects and invited each group to the lab for two sessions (eating both fatty soup and protein soup with the same number of calories and volume). Each session consisted of a 30-minute baseline of soup consumption, a 20-minute post-soup period, an “all you can eat” pizza meal, and a 60-minute post-meal period. Electrogastrogram (a test recording the electrical activity of the stomach, EGG) and electrocardiogram (a similar test recording electrical activity of the heart, ECG) were recorded during each session. Food intake was assessed by the caloric count of the consumed pizza. Several symptoms, including satiety, appetite and nausea, were rated at different times of the study. In a second study, subjects were given the soup appetizer and then taken to an “all-you-can-eat” pizza buffet together in a social setting.

When compared with the protein soup (in this case it was a two-egg soup), the fatty soup (Campbell's Cream of Chicken) significantly reduced the amount of caloric intake with the following meal in both lean (962.0 vs. 1,188.5 calories) and obese (1,331.9 vs. 1,544.6 calories) subjects. A similar reduction in caloric intake was noted in lean subjects eating in the social setting (1,555 vs. 1,825 calories), except that significantly more food was consumed in social sessions compared with the lab setting.

Bottom line:

“In this study, we found that fatty soup as an appetizer reduces food intake by about 20 percent in both lean and obese subjects and may have a therapeutic potential for obesity,” said Jiande Chen, Ph.D., of the University of Texas Medical Branch and senior author of the study. “Our hope is that further studies with similar outcomes may curb those myths and that people will think about what certain foods often thought to be off-limits may be able to achieve for their overall health and weight.”
