A systematic review of the nutritional adequacy of the diet in the Central Andes. Peter R. Send correspondence to Peter Berti, pberti healthbridge. OBJECTIVE: To examine dietary adequacy in the Andean area, including macro- and micronutrient intakes, with a particular focus on rural communities; to highlight nutrition priorities in the Andes; and to identify opportunities for improvement.

Articles reporting data from dietary surveys or nutrition interventions were included. Thirty-four papers or reports published in were included in the final review. The mean and variation in intakes by sex and age group of all presented nutrients were collated and the mean of means were calculated. Intakes of most other micronutrients, including iron, zinc, vitamin A, riboflavin, vitamin B12, folate, and zinc were low, likely resulting in high levels of inadequacy.

Energy intakes were lower than requirements, but it is unlikely to be a common problem, rather, this result was probably due to the njtrition tendency of most dietary survey tools to underreport intake. Increased consumption of animal-source foods would increase fat intakes, while addressing micronutrient deficiencies; however, the impact on the fragile ecosystem of the Andes needs considering.

Indigenous crops, such as lupine bean, quinoa, and amaranth are also rich in fat or micronutrients. OBJETIVO: Analizar la adecuación del régimen alimentario en la zona andina, incluidas las ingestas de macro y micronutrientes, prestando especial atención a las comunidades rurales; señalar las prioridades nutricionales en los Andes; y establecer las oportunidades de mejora.

Se incluyeron artículos que aportaran datos de encuestas alimentarias o intervenciones nutricionales. Las ingestas de la mayor parte de los restantes micronutrientes, incluidos what is the dominant stage in gymnosperms hierro, el cinc, la vitamina A, la riboflavina, la vitamina B12 y el folato, eran bajas, lo que probablemente ocasionaba altos niveles de inadecuación.

Los cultivos autóctonos, como el frijol de altramuz, la quinoa y el amaranto, son también ricos en grasas o micronutrientes. The Andes mountain range extends along the western coast of South America, beginning in Venezuela and running south through Colombia, Ecuador, Peru, Bolivia, to the farthest most reaches of Chile and Argentina. The central Andes comprises four countries-Colombia, Ecuador, Peru, Bolivia-that share a common principles of food science and nutrition notes pdf and history what does apa mean in chineseare relatively poor ranked 85thrd for per-capita gross domestic product 2and subsist on a diet reliant on the nutrtiion and other tubers.

There have been many dietary studies and surveys on nutrition in the Central Andes over the last 40 years. An earlier review assessed intrahousehold distribution of food in low- and middle-income countries; it included four studies from the Andes 3. While limited in scope, it suggested that food is approximately equally-distributed in Andean households, consistent with the relative gender parity of the area 4.

A great ot has been written about the role of the potato and other tubers in the Andean diet 5, 6about indigenous crops and diversity of the Andean diet 7, 8and seasonality in the Andes 9but there has been no comprehensive review of the adequacy of the diet. A review of the nutritional status of Andean people will demonstrate the diet's various positive aspects and inadequacies, allowing og a better understanding of past work and for more informed planning of future nutrition programs.

The objectives of this literature review, therefore, were to examine the dietary adequacy across the Andean area, including macro- and micronutrient intakes, with a particular focus on rural communities; to highlight nutrition priorities in the Andes; and to identify opportunities for improvement. Peer-reviewed and gray literature published sincebeginning with Gursky 11were included in this review.

Google Scholar and Web of Science were also used to search for relevant articles using the same search criteria. Spanish equivalents of the search strategy were used to search the Spanish language literature. Finally, articles and reviews were retrieved through backward searches that is, search of the references in retrieved articles. Articles were scanned for relevance and those published in English or Spanish were included, as well as those that contained dietary data on populations identified as "Andean" or "highland.

Of these selected articles, those containing data from dietary surveys, nutrition interventions, how to be cool on a first date other studies that included dietary data were retained. Data were excluded if they were of lowland populations, published prior toor were of institutionalized subjects.

Fifty-two papers or reports met the inclusion criteria; of these, 34 presented data suitable for inclusion Some, however, were papers reporting from the same survey, and so in all, 29 original research projects or surveys carried out between and composed the literature review. The selection process is shown in Figure 1. From the included papers nuutrition reports, data on the mean daily intakes of energy, macronutrients carbohydrates, protein, and fatmicronutrients vitamin A, thiamin, riboflavin, niacin, folate, vitamin B12, vitamin C, calcium, iron, iodine, and zincand study site locations were extracted.

These data were recorded by age and gender groupings as presented in the papers. The dietary data tool nufrition was also recorded dietary recall, weighed record, or food frequency questionnaire [FFQ]number of subjects, and number of observations per subject. In some cases, data were presented by sub-groups e. In these cases each sub-group was recorded separately. For the presentation of the nutrient intakes by age, an average and a standard deviation SD for each nutrient was calculated at 1-year intervals from birth to 19 years of age, and then another for adults.

For reports that crossed multiple years, the mean was counted multiple principles of food science and nutrition notes pdf e. The standard deviation was calculated as the SD of the means, not a pooled SD from all reports. There were few reports on pregnant or lactating women, so all women pf grouped together. Energy requirements vary with body size. At 10 years, the body weight of Andean children begins to what is primary product dependency farther behind WHO reference growth levels e.

Therefore, for estimates of energy requirements, the body weight of boys and girls, years of age, was estimated as 2 kg less than the WHO reference population; at age 11 food, 3 kg less; at 12 years, 4 kg less, and so on; until at 19 years, both sexes were estimated 10 kg less, or 50 kg females and 60 kg males. Body weight, along with gender and age, can be used to predict basal metabolic rate BMR.

PAL varies from 1. It was hypothesized that the average, rural Andean most of the reviewed data was from rural populations has a PAL of 2. Examples are Principles of food science and nutrition notes pdf definition is consistent with studies of Andean populations what do casual relationship meaning have measured energy expenditure using prniciples water, or heart-rate monitoring. Among Ecuadorian farmers, PAL was 2.

In urban Colombian women, PAL were 1. Thus, this study integrated the physical activity PAL of 1. Estimated nutrient requirements for evaluating diet adequacy were compiled principles of food science and nutrition notes pdf various sources 46, Calculation of the prevalence of nutrient inadequacy requires application of the cut-point method 54which requires the individuals' intakes and is not feasible with summary data. Data sources are summarized in Table 1. When data from a single research site were presented in multiple papers e.

Energy intake data were presented in 26 of these reports, whereas some nutrients were presented only once iodine. Macronutrients were presented frequently: protein in 18 reports; fat, 12; and carbohydrates, Principles of food science and nutrition notes pdf minerals were presented more often than others: iron in 12 reports; calcium, 11; zinc, 6; selenium, 1; and iodine, 1.

There was also variation in the frequency of vitamin reporting: vitamin A in 12 reports; vitamin C, 11; riboflavin, 9; niacin, 9; thiamin, 8; folate, 6; and vitamin B12, 4. One report had data for energy and 15 macro- and micronutrients 42but most presented data on fewer nutrients. The median presented data on three nutrients, 5 reports presented data on only energy, and 1 paper presented only folate intakes The dietary tool used most often was the hour dietary recall 20 studies and weighed records were used in 5 studies.

FFQ were used alone in 1 study, and in combination with an recalls in 1 other study. The sciencw of the data varied among studies. Most studies were from a single community or geographic area, with a small sample not drawn randomly from the study population; a couple of studies were nationally representative 31, Sccience though approximately two-thirds of the populations of the countries reviewed live in urban areas, more data came from rural residents Table 1.

Overall, the reviewed data are not statistically representative of the Andean people. The data may be biased towards poorer households with oversampling of the diets of the rural poor, as a number of the studies intentionally targeted more vulnerable populations or more isolated and traditional populations. Energy and nutrient intake. Average energy intakes from all the included observations are plotted in Figure 2along with FAO recommendations for energy intakes by gender, age, and light and heavy activity levels Intakes increase with age throughout childhood, but are usually less than scieence recommended amount.

Across age groups, iron fpod were relatively high; zinc intakes were moderate; and calcium intakes were low relative butrition requirements. Average principles of food science and nutrition notes pdf and their SDs are presented in Figure 4. The average intakes of most vitamins were low for most age groups. For vitamin A, riboflavin, and folate, average intakes and their SDs from the reviewed literature are presented in Figure 5. This is the first comprehensive review of the literature on dietary intakes in the Andean countries of Bolivia, Colombia, Ecuador, and Peru.

The data represents a range of ethnic groups, age groups, genders, and socioeconomic levels, and includes urban and rural populations. So while there were 34 different reports, from 29 unique studies, there were so many different subpopulations and most using non-representative sampling methods that only crude statistics could be applied to the summary statistics from each paper-namely, the mean of the means and the standard deviation long distance relationship best ideas the means, and these summary statistics are only approximations of the underlying real nutrient intakes in the Andes.

Nonetheless, there are principles of food science and nutrition notes pdf implications from the data. Nutritiin reported energy intakes are low throughout the lifespan Figure 2. For children less than 2 years of age, this may be in part because breast milk intake is underestimated. In children years of age, the average intakes fall near the boundary of energy requirements for a light activity level. In the teen years and into adulthood, many of the average energy intakes are much less than estimated requirements, even for a light activity level.

Such low intakes almost surely reflect underreporting. While an individual may have energy intakes less than requirements for a day or a short period, and pre-harvest shortages have been observed in the Andes 9it is not possible that an entire population has lower-than-required intakes over a period of years. Not only are the reported intakes less than required for heavy activity the level of typical rural populationsthey often fall short of requirements for light activity, and in the long-term, would not suffice to sustain life.

We conclude, therefore, that most of scienfe reports underreport real food intakes-a common problem with dietary recall surveys ppdf Also, it is not known if underreporting occurs evenly across all foods e. If the underreporting is across all foods, then the underreporting of micronutrients is likely proportional to the underreporting of energy.

If the underreporting is selective, then there might be only minimal underreporting of micronutrients. Therefore, it can be assumed that intakes that appear adequate, despite the underreporting, would be adequate if accurate data were available. However, intakes that are inadequate may be truly inadequate, or simply appear to be inadequate due to underreporting. This limitation colors the notee of the discussion.

Fat intakes appear to be higher in urban areas and wealthier countries, i. The consequences of insufficient fat intake are broad and deep, leading to poor child growthimpairing neurobehavioral development 58and immune system function Some of the impacts are due to insufficient total fat intake, and others are due to insufficient intake of specific essential fatty acids Site-specific recommendations regarding fat fpod required.
