The contribution of the various food groups to the nutrient intakes of a group of independently-living elderly individuals in Toronto is described. The pattern of meal and food intakes generally provided enough of the nutrients, excepting calcium, to meet the Recommended Nutrient Intakes for Canadians. Mean energy intake was low. It is suggested that if relatively small amounts of the foods ingested at the different meals are raised, it will likely provide enough energy and all the nutrients to satisfy the recommended levels of intake.
OBJECTIVE: To quantify the consumption of unfiltered coffee brews, which contain the cholesterol-raising diterpenes cafestol and kahweol, in elderly subjects. DESIGN: Interviews of randomly selected elderly in the 1993 SENECA Study on Nutrition and the Elderly in Europe. SETTING: Nine towns in eight European countries (Denmark, France, Italy, the Netherlands, Portugal, Switzerland, Poland, and Northern Ireland/United Kingdom). SUBJECTS: 962 relatively healthy elderly persons (460 men, 502 women) born between 1913 and 1918. MAIN OUTCOME MEASURE: Daily coffee consumption, classified by brewing technique. RESULTS: About 90 percent of the examinees were daily coffee users in Roskilde/Denmark (population means; men 530 ml/d, women 425 ml/d) and Culemborg/the Netherlands (men 513 ml/d, women 285 ml/d), against only 12% in Marki/Poland (population means; men 14 ml/d, women 36 ml/d) and 7% in Coimbra/Portugal (men 8 ml/d, women 0 ml/d). Drip-filtered and instant coffee, which are poor in diterpenes, were the prevalent types in most survey towns. Espresso and mocha coffee, which contain intermediate amounts of diterpenes, were consumed daily by 31% of the coffee drinkers in Switzerland and by all coffee drinkers in Italy, but intake was too low to substantially affect serum cholesterol levels. Consumption of brews that are rich in diterpenes, such as cafetiere, boiled, or Turkish/Greek coffee, was negligible in all survey towns. CONCLUSIONS: Coffee drinking is common among elderly people in some European countries, but intake of cafestol and kahweol with unfiltered coffee brews is low.
Provincial nutrition surveys of adults were conducted between 1990 and 1999 in Canada. Eight reports have been issued, and one is forthcoming. The purpose of this study was to estimate the national dietary intake of adult Canadians, using the publicly available data. Group mean-nutrient-intake data from 16 915 adults, aged 18 to 84 years, from published provincial reports were collated by age and sex for each of 9 provinces (Manitoba data were unavailable). Using Canadian census data appropriate to the year of collection, intake data were weighted to provide 1 national intake value for each nutrient, by 8 age and sex categories. In general, the energy and nutrient intake of adults decreased with age. For every age group, with the exception of vitamin C, intake of nutrients by men was greater than that by women. On the basis of a comparison of recently recommended intakes (Dietary Reference Intakes), the nutrients that are of concern because of inadequate intake include dietary fibre, calcium, magnesium, and folate. The data demonstrate the impact of folate fortification on folate intake; the mean intake became twice that of prefortification levels. This study used group mean-intake data; therefore, we cannot make definitive conclusions about the prevalence of inadequacy for the nutrients. Because of limitations with some provincial response rates, our data should not be construed as representative of the Canadian population. However, because these surveys were completed between the 19701972 Nutrition Canada Survey and the 2004 Canadian Community Health Survey, these population-weighted data might be a useful point of comparison for monitoring trends in nutrient intake from food.
The nutritional adequacy of commercial baby foods is assessed from data derived from a longitudinal nutrition survey of 400 infants in Canada. On the average, the nutrient intakes from infant food meet or exceed the recommended daily allowances for most nutrients. Most infants would not be able to meet the minimum daily requirements for iron, B vitamins, or calcium if infant cereals were not fortified.
