Evaluation of food consumption and dietary patterns in Spain by the Food Consumption Survey: updated information.

Background/Objectives:The Food Consumption Survey (FCS), conducted for over 20 years by the Spanish Ministry of Agriculture, Fisheries and Food (MARM), is the most reliable source of data to evaluate the food consumption and dietary patterns of Spain. The aim of this study was to assess population food availability per capita per day, which allows the calculation of energy and nutrient intake and comparison with the Recommended Nutrient Intakes for the Spanish population. In addition, different markers of the quality of the diet have been evaluated.Subjects/Methods:The sample consisted of consumption and distribution data, obtained from the nationwide representative FCS for the period 2000–2006. A two-stage sampling method was applied, where in the first stage the units to be sampled were towns or local entities, and in the second stage households that were going to be part of the final sample from those entities were selected. Units consisted of towns or local entities in the national territory. The sample size was 619 selected entities. Units in the second stage were households from the selected towns (8200 homes). The data allowed the calculation of energy and nutrient intakes, using food composition tables. The quality of the diet was also evaluated: the adequacy of the diet in meeting the recommended intakes for energy and nutrients; energy profile; dietary fat quality; dietary protein quality; nutrient density; and Mediterranean diet adequacy indices. The present data were compared with previous data obtained by our research group in 1964, 1981 and 1991.Results:Using the most recent data, average intake comprised milk and derivatives (379 g/person/day), fruit (310 g/person/day), vegetables and greens (302 g/person/day), cereals and derivatives (214 g/person/day), meat and meat products (179 g/day), fish (100 g/person/day), oil and fat (48 g/person/day), precooked food (34 g/person/day), eggs (32 g/person/day), and legumes and pulses (11.9 g/person/day). There was also a high consumption of non-alcoholic beverages (433 g/person/day) and alcoholic beverages (247 g/person/day). In consequence, meat and meat product consumption was higher than the recommendations, whereas for cereals and their derivatives, vegetables and greens, fruit, and legumes and pulses, consumption was below recommendations for the Spanish population. Some staple and traditional Mediterranean foods (bread, potatoes and olive oil) showed a dramatic decline when compared with data from Household Budget Surveys in 1964 data. Energy intake declined by about 300 kcal/person/day, when compared with the 1964 mean consumption. Insufficient nutrient intakes were found in the young adult population for zinc and folic acid in both sexes, and for iron in women, when compared with dietary reference values.Conclusions:Food consumption patterns in Spain and energy and nutrient intakes have changed markedly in the last 40 years, differing at present from the traditional and healthy Mediterranean diet.

Spatial patterns of soil pathogens in declining Mediterranean forests: implications for tree species regeneration

Soil-borne pathogens are a key component of the belowground community because of the significance of their ecological and socio-economic impacts. However, very little is known about the complexity of their distribution patterns in natural systems. Here, we explored the patterns, causes and ecological consequences of spatial variability in pathogen abundance in Mediterranean forests affected by oak decline. We used spatially explicit neighborhood models to predict the abundance of soil-borne pathogen species (Phytophthora cinnamomi, Pythium spiculum and Pythium spp.) as a function of local abiotic conditions (soil texture) and the characteristics of the tree and shrub neighborhoods (species composition, size and health status). The implications of pathogen abundance for tree seedling performance were explored by conducting a sowing experiment in the same locations in which pathogen abundance was quantified. Pathogen abundance in the forest soil was not randomly distributed, but exhibited spatially predictable patterns influenced by both abiotic and, particularly, biotic factors (tree and shrub species). Pathogen abundance reduced seedling emergence and survival, but not in all sites or tree species. Our findings suggest that heterogeneous spatial patterns of pathogen abundance at fine spatial scale can be important for the dynamics and restoration of declining Mediterranean forests.

The Spanish diet: an update

BACKGROUND/AIMS The Food Consumption Survey, conducted for over 20 years by the Spanish Ministry of Agriculture, Food and Environment (MAGRAMA), is the most reliable source of data to evaluate the food consumption and dietary patterns of Spain. The aim of the present article was to review the diet trends in Spain and its evolution. Food availability assessment per capita per day, which allows the calculation of energy and nutrient intake and comparison with the Recommended Nutrient Intakes for the Spanish population is described. In addition, different markers of the quality of the diet have been also evaluated. METHODS The sample consisted of consumption and distribution data, obtained from the nationwide representative Food Consumption Survey for the period 2000- 2012. A two-stage sampling method was applied, where in the first stage the units to be sampled were towns or local entities, and in the second stage households which were going to be part of the final sample from those entities were selected. Units consisted of towns or local entities in the national territory. The data allowed the calculation of energy and nutrient intakes, using the Food Composition Tables (Moreiras et al, 2013). The quality of the diet was also evaluated: the adequacy of the diet in meeting the recommended intakes for energy and nutrients; energy profile; dietary fat quality; dietary protein quality; nutrient density; Mediterranean diet adequacy indices. The present data were compared with previous data obtained by our research group in 1964, 1981 and 1991. RESULTS Using the most recent data, average intake comprised: milk and derivatives (356 g/person/day), fruits (323 g/person/day), vegetables and greens (339 g/ person/day), cereals and derivatives (197 g/person/day), meat and meat products (181 g/day), fish (88,6 g/person/ day), oils and fats (41,6 g/person/day), sugar and derivatives (25,6 g/person/day), eggs (27,1 g/person/day), legumes (13,9 g/person/day) . There was also a high consumption of non-alcoholic beverages (437 g/person/day) and decreasing for alcoholic beverages (192 g/person/day) compared to previous surveys. In consequence, meat and meat product consumption was higher than the recommendations, whereas for cereals and their derivatives, vegetables and greens, fruit, and legumes and pulses, consumption was below recommendations for the Spanish population (GRUNUMUR, 2004; SENC, 2007). Some staple and traditional Mediterranean foods (bread, potatoes and olive oil) showed a dramatic decline when compared to data from Household Budget Surveys in 1964 data. Energy intake showed a marked decline when compared to the 1960s mean consumption, and show marked differences for food groups contributors. Energy profile shows too much coming from lipids vs carbohydrates and slightly higher from proteins. CONCLUSION Food consumption patterns in Spain and energy and nutrient intakes have changed markedly in the last forty years, differing somewhat at present from the traditional and healthy Mediterranean Diet.

The ANIBES Study on Energy Balance in Spain: Design, Protocol and Methodology

Energy Balance (EB) is an important topic to understand how an imbalance in its main determinants (energy intake and consumption) may lead to inappropriate weight gain, considered to be “dynamic” and not “static”. There are no studies to evaluate EB in Spain, and new technologies reveal themselves as key tools to solve common problems to precisely quantify energy consumption and expenditure at population level. The overall purpose of the ANIBES (“Anthropometry, Intake and Energy Balance”) Study was to carry out an accurate updating of food and beverage intake, dietary habits/behaviour and anthropometric data of the Spanish population (9–75 years, n = 2009), as well as the energy expenditure and physical activity patterns. Anthropometry measurements (weight, height, body mass index, waist circumference, % body fat, % body water) were obtained; diet was evaluated throughout a three-day dietary record (tablet device) accompanied by a 24 h-dietary recall; physical activity was quantified by questionnaire and accelerometers were also employed. Finally, information about perception and understanding of several issues related to EB was also obtained. The ANIBES study will contribute to provide valuable useful data to inform food policy planning, food based dietary guidelines development and other health oriented actions in Spain.
