The department of nutrition at the Loma Linda University School of Public Health will be conducting a new food study to observe the effects of different types of n-3 fatty acids on blood lipids in healthy adults. The study will begin September 16, 2007, and continue through May 16, 2008. 

Participants will be served dinner at Loma Linda University, and packed breakfasts and lunches will be sent home with participants each day.

Regular consumption of n-3 fatty acids from both marine (EPA/DHA) and plant (ALA) sources has been shown to produce significant cardiovascular health benefits in both normolipidemic and dyslipidemic humans.

This proposed study will compare the effects of an ALA-rich diet versus an EPA/DHA-rich diet on blood lipids and other selected coronary risk factors in healthy adults. For the first time, it will look at the possible synergistic effect of combining ALA and EPA/DHA in the diet.

The study will consist of a carefully controlled feeding study for 25 weeks. All participants will consume a typical U.S. lacto-ovo vegetarian diet for one week. This will be followed by assignment to one of three groups, each of which will spend eight weeks on a control diet, eight weeks on a diet including flaxseed oil and walnuts, and eight weeks on a diet including a micro-algae oil supplement. There will be a four-to-six week break between each phase. All diets will be lacto-ovo vegetarian.

There are many benefits to those who will be invited to participate. Foremost, for 25 weeks they will not have to purchase or cook food for their own consumption. All food will be furnished free of charge by the study. Those who complete the study will receive their personal blood lipid results and a small monetary compensation.

Additionally, there is the satisfaction of making a contribution to the growing knowledge of nutrition and heart health.

The department of nutrition is looking for healthy adults between the ages of 20 and 70 who are lacto-ovo vegetarian—or willing to eat an exclusively lacto-ovo vegetarian diet for 25 weeks—and within easy driving distance of Loma Linda University. They must be willing to consume flaxseed oil, walnuts, and a micro-algae oil supplement.  They must be available to come to the University six days a week (Saturdays excepted) for dinner and must commit to eating only the food provided by the study for 25 weeks.

All those interested in participation can obtain an application at the study website, www.nutstudies.org, or by sending an e-mail request to nutstudies@llu.edu. Applications can also be sent by mail upon request at (909) 558-4300, extension 47170.

Funding for this study is provided by the Center for Health and Nutrition Research at the University of California, Davis.
