Summary:
The NE 172 Regional Research Project Summary Report is presented in two parts;
I.
Key decisions made during the annual meeting and
II.
Meeting minutes for the annual meeting held June 9-11 in Ogunquit, Maine
I.
Key decisions made by members of the collaborative research project.
A. Members expressed a strong commitment to advancing the understanding of elderly
nutrition issues and research through continued collaborative efforts. Possible funding
sources included the renewal of the current grant cycle NERA, as well as funding through
the IFAFS (Initiative for Future Agriculture and Food Systems) programs.
1
Review of the requirements for project designs and funding were encouraged, since the
benefits of the group’s collaborative efforts is evidenced by the multiple research
initiatives successfully completed during this project’s duration. In addition, the
established network of professional support and expertise that has developed through
these collaborative efforts could be utilized to design and expand comprehensive regional
research projects.
Research goals for the elderly population, though not necessarily limited to the elderly,
that could be expanded or initiated as part of the renewal project development included
the following:
1. To determine the use of functional foods and supplements and document their
role in elderly nutrition. Methods used to estimate actual supplement usage and
nutrition product information would need to be evaluated given the challenge
associated with such documentation .
2. To use and evaluate dietary assessment strategies and tools used to determine
portion sizes and weights of foods, and to determine their impact on dietary
assessment.
3. To develop and assess culturally and educationally appropriate health and
dietary screening tools.
4. To evaluate the function of antioxidants as measured by “ORAC” (oxygen radical
absorption capacity), by “FRAP” (ferric-reducing ability of plasma), or by other
assessment means; and to consider antioxidants and phenolic compounds in
relation to the health of the elderly.
5. To continue and expand research on carotenoid status, measured in the diet,
serum, and/or measured as macular pigment optical density (MPOD). Based on
the preliminary results funded by the present grant cycle, investigations that
further an understanding of the metabolic milieu associated with BMI and
carotenoid status appears warranted.
6. To identify consumer concerns and interests as advances in biotechnology
confront consumers in the nutrition marketplace.
7. To continue to evaluate the impact of food security and availability on nutrient
intake and health status.
B. Initial results presented for the tri-state carotenoid screener were based on reported fruit
and vegetable consumption, as the major food sources of carotenoids. Reported fruit and
vegetable consumption indicated a significant relationship to serum carotenoid
concentrations. In addition, as reported fruit and vegetable intake increased, so did
MPOD. The goal is to expand the screener capacity to include carotenoid intake and
possibly antioxidant quantification. Strategies to make the screener adaptable to various
populations were explored. Participants discussed the need to make the screener
culturally appropriate and user friendly, especially for those who may not have English as
their primary language.
C. Collaborators were committed to designing comprehensive Institutional Review Board
documents. The need to seek approval from all institutions involved in collaborative
research efforts was discussed. Members were encouraged to draft informed consents
that were explicit and comprehensive in nature so that if further analysis or expanded
collaboration was advisable, participants in the research study would have been
adequately informed of such a possibility.
2
D. The proposal to write a series of articles for submission consideration in Topics in Clinical
Nutrition was enthusiastically considered since both the process of collaboration and the
actual research results could prove to be quite instructional for health professionals and
researchers.
E. Research results from participating institutions were discussed via poster session to
highlight the depth and diversity of the projects supported in whole or in part funded by
NE 172. (See end of the actual minute’s section for specific titles of the posters
presented).
II. Meeting Minutes:
Presiding: Joanne Curran-Celentano
Joanne began by thanking Dick for arranging the meeting and Carol for dinner at her home on
Sunday evening. The group sent its condolences to Mary Jane who lost her husband last year.
The following accomplishments of NE-172 members were recognized: Carol Lammi-Keefe won
the American Dietetic Association Dietetics Research Award, Nancy Fey-Yensan was tenured
and promoted to Associate Professor, Joanne Burke earned her PhD degree, and Crystal
Lariviere earned her MS degree. Three members were also participants on IFAFS grants: Carol
Lammi-Keefe (PI), Nancy Cohen (co-PI), and Joanne Curran-Celentano (co-PI).
The minutes of the 2001 Technical Meeting were reviewed and approved.
CSREES Reports - Gloria Wyche-Moore described the new electronic system to submit annual
reports. The minutes of the annual meeting will also be submitted to Gloria as part of the new
system. Salei’a Afele-Faamuli provided an overview of USDA and CSREES and described some
changes planned for the upcoming year. Mel Mathias provided an update on the budget and
discussed opportunities for funding.
3
Station Reports - All stations reported their activities over the past year. Hard copies of reports
were provided to meeting participants.
Tristate Carotenoid Screener - UNH and URI stations reported on activities over the past year to
validate the carotenoid screener. A ‘calculator’, or computer program that can calculate specific
carotenoid values from the screener, is being developed. Ron Prior discussed adding ORAC
values to the calculator. URI and UNH plan to collaborate on a study this fall to evaluate dietary
data and macular pigments measures of low-income seniors in Rhode Island.
Institutional Review Board Approval - Joanne discussed issues related to IRB approval of studies
at individual universities and the ability to then share this data with others in our multi-state
project. She encouraged stations to work with individual IRBs to craft language that will allow for
the possibility of data to be shared with other stations in the project in the future.
Project Renewal - The group agreed to try to renew the project for another 5 years. The
requirements for renewal and some possible areas for continued research were discussed. We
believe that the Critical Review portion of the proposal is due in January or February. Gloria will
check on the deadlines and guidelines for project renewal and provide us with this information.
Possible research areas for the project renewal were discussed and include:
 Portion size and weight of food
 Functional foods (Where does this fit in the nutritional needs of the elderly?)
 Supplements
 ORAC (further development)
 Macular pigment optical density and BMI, diabetes, health issues, and underserved
populations
 Adapting the screener to make it culturally appropriate
 Consumer driven agriculture (What does the consumer want?)
 Food security
IFAFS - The members agreed that we should try for IFAFS funding. Mel said that the outlook for
IFAFS funding is good and is projected to increase between FY 2002 - 2006. IFAFS supports
conceptually-based applied research and outreach activities. The grants may be either multidiscipline or multi-state and are commonly $2,000,000 for 4 years. A subgroup agreed to look at
the possibility of submitting an IFAFS grant (Joanne C-C., Joanne B., Crystal, Nancy C., Nancy
F-Y, and Carol). Gloria said she would provide the group with information on funding from NERA.
4
Journal Article - Judy Gilbride suggested that the project might want to write a series of articles
for an issue of Topics in Clinical Nutrition. The articles could show the project as a model for
education and highlight what has been done over the years and how these accomplishments
have affected practice. Helen agreed to coordinate the journal writing activity and Judy will send
us the guidelines for the Journal. Outlines for the articles are due in September! A rough outline
was discussed:
 Title: Protein to Lutein - The Evolution of the Northeast Regional Project
 History of the Project - Dick
 Diet Assessment Methods - Helen, Diane, Carol, Nancy C., Mary Jane (?), Katie (?)
 Diet-biochemical-functional status using antioxidants as a model - Joanne C-C., Joanne B.,
Ron
 Carotenoid/ORAC screener - Joanne C-C., Joanne B., Nancy F-Y., Cathy, Ron
 Strategies for practitioners (qualitative and quantitative research) - Nancy F-Y., Ann
A poster session was held on Monday afternoon showcasing the activities of the members. A list
of posters is attached.
The Executive Committee met on Monday evening. The committee confirmed the date of the
next meeting, discussed the process of renewing the project, and developed a plan to submit the
previous annual reports. Copies of the annual reports will be distributed to members in the future
either as hard copies or posted on our website. No election of officers was needed as current
terms run until 2003.
A design for the project’s website was discussed and approved by the members. It was decided
that this year’s minutes, member list, and project timeline should be sent electronically as
attachments rather than as hard copies.
The next meeting is scheduled on June 9-11, 2003 (Monday 12:00 - Wednesday 4:30) in
Annapolis, MD, hosted by the UDC and UMD.
The meeting was adjourned at 11:40 AM.

Progress of Work and Principle Accomplishments and Impacts:
Significant accomplishments are reflected in meeting the goals and objectives
identified in the original proposal and are evaluated each year at the annual
meeting.
OBJECTIVE 1 - TO EVALUATE BIOMARKERS OF NUTRITIONAL RISK,
WITH AN EMPHASIS ON ANTIOXIDANT STATUS.
OBJ 1: Experiments 1a and 1b. Dietary, supplemental, and serum
carotenoids investigated as determinants of MPOD
Accomplishments: The pigment located in the foveal region of the retina,
referred to as the macular pigment (MP) is composed of the carotenoids lutein
and zeaxanthin. Since humans do not synthesize carotenoids, these pigments
must originate from the diet. A limited number are avaiulable as supplements.
Carotenoids have been purported to act as antioxidants and to provide
protection to the visual system. Much remains to be learned about carotenoid
intake absorption and deposition. Two studies were completed in the past year at
UNH on carotenoids and their relation to carotenoid deposition in the retina
measured as macular pigment optical density (MPOD).
OBJ. 1: 1a. In the first study, selected dietary data collected at UNH was
analyzed in relation to serum carotenoid concentrations and carotenoid
deposition in the macula of the eye in adults aged 45-73 years. Significant
associations were found for reported dietary carotenoids lutein /zeaxanthin intake
and MPOD, as well as for serum concentrations of the carotenoids lutein and
lutein/zeaxanthin and MPOD. However, it appears women and men may respond
differently to carotenoid intake as measured by serum concentrations and
MPOD. Additional research should be conducted to further investigate potential
gender differences. The development of optimal dietary carotenoid intake and/or
supplement advice is dependant upon an understanding of the functions of
carotenoids as well as the many variables that influence carotenoid status,
including differences in responses possibly based on gender or lifestyle.
Impact OJT 1: 1a Based on the significant associations between reported dietary
carotenoid intakes and serum carotenoid concentrations and MPOD, both MPOD
and serum carotenoid concentrations appear to be biomarkers for nutritional
status.
OBJ. 1: 1b. In the placebo-controlled study, supplements of lutein were given to 6
of 11 subjects (20-48 years). A month of supplement use (6 mg) resulted in
significantly higher serum carotenoid concentrations being detected in
7
supplement users, but no significant changes were detected in MPOD, compared
to the placebo group in which there were no changes.
Impact OBJ. 1: 1b: Many individuals turn to supplements as an alternative to
carotenoid consumption via dietary sources. Additional research is needed to
determine if carotenoids from supplements are absorbed and deposited at a
similar rates as those derived from whole foods.
OBJ 1: Experiments 2a-2b. Effects of increasing foods high in antioxidat
capacity (primarily food flavonoids) as assessed by the Oxygen Radical
Absorbance Capacity (ORAC) assay on biomarkers of antioxidant status.
Accomplishments: Research on antioxidant absorption, metabolism, utilization
and detection continue to evolve. In the original proposal, antioxidant activity
was to be detected using ORAC. The additional FRAP assay (ferric-reducing
ability of plasma), was utilized to both assess antioxidant status and to compare
the FRAP test with the ORAC.
OBJ 1: 2a. Research from the antioxidant capacity (AC) of prune juice (PJ),
prunes (PR) and blueberries (BB) was assessed in six women aged 60-70 years
to determine how consumption of a single meal would impact results of plasma
ORAC or FRAP since both tests are used as measures of antioxidant capacity.
Results from the ORAC analysis differed from those of FRAP, indicating that
these assessment tools differed in their ability to detect antioxidant reactions in
this study at the human USDA Human Nutrition Center on Aging, Boston.
Impact: 1: 2a Documentation of differing results based on assessment strategies
is important in order to understand factors that can influence results and to
assess differences in outcomes within and between studies.
OBJ 1: 2b. In a pilot study at the Univ. of Maine, in which 24 women aged 60-90
years were assigned to an experimental BB consumption group (n=12) and a
non-consuming group (n=12), both ORAC and FRAP tests (p=0.036) results
were significantly increased in the BB consuming group, with no significant
change in the control group.
Impact: 1: 2b. Ultimately, determining methodologies that are most appropriate
for antioxidant research will lead to a greater understanding of these complex yet
ubiquitous biological compounds.
8
OBJ 1: Experiment 3a-3b. Retrospective analyses of plasma biomarkers
and antioxidant status.
OBJ 1: 3a. Working collaboratively with ACNC, researchers from PA, Tufts and
NH plan to incorporate ORAC data into their food databases. Once completed,
retrospective analyses of dietary intake and health indicators (such as MPOD in
NH), based on ORAC can be conducted. This will expand upon work completed
in previous years by collaborators from Tufts and CT, which examined food
intake data and health outcomes in relation to ORAC status.
OBJ 1: 3b. In addition, researchers from UNH plan to collaborate wuth those
from CT. to evaluate the potential relationships among carotenoids, fatty acid
status, and MPOD.
Impacts 3a and 3b: Assessment of the influence of dietary components such as
antioxidants on health status is dependent upon both precise measurement in
biological samples and dietary estimates using comprehensive food databases.
OBJ 1: Experiment 4a-4b. Additional biological assessments and
nutritional implications
OBJ 1: 4a. Trans fatty acids (TFA) are formed during hydrogenation of fats and
oils and are present in the diet throughout the life-span. The presence of TFA
has been shown to interfere with the normal elongation and desaturation of the
essential fatty acids arachidonic, (AA) and decosahexaenoic acids (DHA) to their
biologically active long chain metabolites. Essential fatty acids are not only
utilized for eicosanoid formation, but also for central nervous system functioning
and in retinal development. Researchers from CT determined trans fatty acids
were inversely related to both AA and DHA concentrations in pregnant women.
Future plans include collaborating with Cornell to share urine specimens and
assess vitamin E metabolites.
Impact: Trans fatty acid ingestion may have implications for individuals
throughout the lifespan since diets high in trans fatty acid composition may
interfere with the formation of AA and DHA.
OBJ1: 4b. Dietary intake and urinary metabolites of vitamin E.
The overall objective for the Cornell research project was to investigate urinary
metabolites of vitamin E (tocopherols) as potential biomarkers of dietary intake of
vitamin E and possibly of vegetable oils, the major dietary source of vitamin E.
The research compared a) the of rates of excretion of metabolites of the common
dietary tocopherols with dietary intakes of the substrate tocopherols in 11
9
subjects consuming standardized diets under controlled circumstances and b)
examined the relationship of urinary excretion of vitamin E metabolites with
vitamin E intake as estimated by various food frequency questionnaire (FFQ)
instruments (Objective 3). At the time of the annual meeting, the urinary
metabolite data was available for weeks 12 and 13 and indicated that most
subjects were near but not at a steady state of tocopherol excretion by week 13,
and that the tocopherol content of the diet was less than the average intake of
tocopherols from the self-selected diets of the subject at entry into the metabolic
study. Though the researchers had hypothesized that after 13 weeks on the
standardized diet all subjects would exhibit the same rate of excretion for a given
tocopherol, the excretion rates differed from 2 to 4 fold between subjects. The
researchers plan to further investigate in urinary metabolites can be used as
markers of vitamin E intake by comparing subject variation before diet
standardization with that after standardization.
Impact: For urinary tocopherol metabolites to be ideal markers for tocopherol
intake, the variation in excretion should only be a function of the variation in
intake yet in this study, intake was standardized for 13 weeks and considerable
variation in excretion persisted.
OBJECTIVE 2: TO IMPROVE DIETARY INTAKE ASSESSMENT METHODS
AND SCREENING PROTOCOLS TO IDENTIFY NUTRITIONAL RISK
OBJ 2: Experiments 1a-1d: Investigations were designed to examine
predictors of nutrition risk and low fruit and vegetable intake in diverse
populations.
OBJ 2: 1a. Researchers from UMASS surveyed food bank recipients residing in
the western and central regions of the state to assess food insecurity, food
choice, and health indicators. Older food pantry recipients (+70 yrs.) were more
likely to eat alone, have an illness that impacted their diet, and be ranked as high
risk by the DETERMINE scale. They were also more likely to use supplements
but less likely to use food stamps than recipients aged 51-70 yrs. Recipients
showed a low frequency of fruits (1.39x per day) and vegetables (2.06 x per day).
More information is needed to determine the barriers that contribute to the
inadequate distribution of fruits and vegetables at food pantries.
OBJ 2: 1b. Dietary information from case studies using a qualitative approach by
the researchers from the DC revealed that eating behavior might be more
influenced by dietary knowledge in concert with evidence of impending or
diagnosed morbidity rather than by dietary knowledge alone. A second study
suggested by the results from the research relates to the use and accurate
10
assessment of “dietary supplements.” Initially, subjects reported only the
sporadic use of supplements, however upon further investigation it was
determined that all six participants regularly used a commercially available, over
the counter nutrition drink (Ensure). It appears these types of products were not
initially perceived as a “dietary supplement.” As the number of
nutriceutical/fortified foods continues to expand beyond Total Cereal and
Ensure type products, researchers will need to devise questions that accurately
document use o these “supplement” sources
OBJ 2: 1c. Researchers form Tufts, UNH and PA continue their evaluation of
dietary assessment tools (including screeners, FFQ, and dietary recalls) to
estimate carotenoid and antioxidant intake. Results from UNH comparing three
FFQ showed mean total daily carotenoid intakes between 10.5 to 15.5 mg/day
depending on the FFQ utilized. Using a short fruit and vegetable screener,
significant correlations were found for reported fruit and vegetable intake and
serum carotenoid concentrations and MPOD. Similar, though not identical, rank
orders for the carotenoids were obtained by each of the FFQ utilized.
OBJ 2: 1d. Researchers plan to evaluate 200 rural white elderly participants from
PA by food groups and ORAC values. This will expand upon previous work
completed by PA researchers in which food group intake was estimated from the
Nutrition Risk Screener, 24-hour recalls, and the Block FFQ; food group
adequacy was compared using the Food Guide Pyramid and Five-A-Day
guidelines. This will also expand research discussed in OBJ 1; experiment 3 and
OBJ 2: experiment 2 in which ORAC status is being evaluated as a potential
biomarker of nutrition risk.
Impact: Minimally and non-invasive assessment instruments that serve as
indicators of nutrition and health status provide valuable information to clinicians
and researchers as they attempt to provide comprehensive, effective health care
and formulate public health policy.
Objective 2: Experiment 2: Exploration of food patterns which may be
associated with diet related protection against oxidative stress.
2a. Validity of the Block FFQ was assessed by researchers from PA by
comparing FFQ results to five- 24 hour recalls collected over ten months in 181
elderly adults. Correlations between methods for key dietary components (fat,
saturated fat, cholesterol, Vit.C, Vit. D and calcium ranged from 0.41-0.61 and
may provide reasonable estimates while for other nutrients (protein,
carbohydrate, Vit. B6, Vit. A., Vit. E, Fe, Mg.), and food group correlations were
low. Plasma biomarkers for the folate, Vit D and Vit B6 were not well correlated
11
with the FFQ (< 0.02). With further examination by intake quartiles, 65% more
would be misclassified by one quintile: 23% by more than one. The data suggest
that this FFQ would not provide reasonable estimates of selected nutrient intake.
Impact OBJ 2: 2a : FFQ questionnaires are used in many nutrition studies, yet
the results may be comparable to those obtained using 24 hour recalls.
OBJ 3 – 2 To estimate the relationships between dietary assessments and
biochemical markers.
See Obj 1 Exp 4
OBJ 4: 1 Awareness and attitudes of AMD, F/V consumption
Modeled after the Dietary Approaches to Stop Hypertension (DASH) a study was
designed to examine factors associated with consumption of the recommended
DASH food groups F&V and LFD (low fat dairy). The sample (n=592) was
randomly selected from the PA Pharmaceutical Assistance Contract for the
Elderly who had HT. The sample (85% female, 76% white, BMI 29.5) showed
women and those with greater social support were more likely to report daily
consumption of LFD and F&V (P<.05). Persons reporting daily LFD were more
likely to be white (p=.001), have higher education (p=.008) and to exercise
(p=.006). Impact. These findings suggest the need for further examination of
characteristics that may influence adherence to dietary recommendations to
improve blood pressure in older adults.
At RI, community-based programs were presented to support elders with visual
impairments focused on AMD and nutrition. Subjects were pre and post tested on
questions regarding self-efficacy and intent to change behavior. The program
was provided in 10 sites to 108 subjects. Pre-assessment revealed the subjects
had little or no knowledge of AMD, its causes and possible prevention strategies.
Post assessment indicated a willingness to change behaviors to increase intake
of protective foods in their diets.
Similarly, MD used a previously developed survey instrument to assess the level
of knowledge and awareness of AMD among older individuals. The sample
included 126 subjects (50 males, mean age 72 years) who were in general good
health and well educated. A total of 11 subjects indicated they had been
diagnosed with AMD.
The level of awareness of AMD and knowledge of behaviors relative to a variety
of health issues (foods rich in lutein, smoking, wearing UV protective lenses,
supplement use, exercise, blood pressure and cholesterol control) was
assessed. A sample of 74 subjects completed the NCI Diet History Questionnaire
to determine the extent that subjects habitually consume greens and other
dietary sources of lutein.
12
Results thus far indicate that there is a relatively low awareness of AMD among
elderly individuals. Even among those diagnosed with AMD, having a close
relative with AMD or stating that they are familiar with AMD, there appears to be
a general lack of awareness about lutein and foods containing lutein.
Impact: Taken together it appears that there are opportunities to increase
awareness of dietary interventions that may delay onset of aging eye disease
and that given the proper information, this age group appears willing to make
dietary modifications that may improve nutritional risk status. OBJ 4 Exp 2 is
focused on developing and adapting educational approaches to reduce
nutritional risk.
