Seasonal variation in food intake and the interaction effects of sex and age among adults in southern Brazil

Abstract

Background/Objective: Because studies have evidenced variations in nutrient intake, 1

Seasonal variation of diet quality in a large middle-aged and elderly Dutch population-based cohort

“…A larger seasonality in diet quality and in more food groups was observed among men and among participants with high BMI than in their counterparts. The sex differences in the seasonality of food groups are in agreement with previous studies [9,11,46], and can be explained by a better diet consciousness among women [22,49]. A better diet consciousness could also explain the more stable diet quality of participants with lower BMI.…”

“…As for fruit intake, we hypothesize that those who do not eat fruits regularly are more likely to eat it along with other food groups with a strong seasonal pattern, e.g., legumes and nuts. The stable intake of vegetables and fruits throughout the year in our study opposes the seasonality observed in previous studies [10,11,45,46], and could be attributed to the constant availability of affordable vegetables and fruits in the Netherlands [48]. However, because only 50% of our population met the guidelines for vegetable and fruit intake [22], aiming to increase the intake of vegetables and fruits may contribute to enhance overall diet quality.…”

“…We are not aware of comparable studies addressing the seasonality of nuts intake, although people could prefer them in colder months for its fat content. The summer peak of sugar-containing beverages intake has also been reported before [46,47], and is attributed to the preference for sweet refreshing beverages in summer. Probably, these are replaced in winter by warmer beverages, such as tea and coffee, as we and others [47] found.…”

Seasonality of nutrient intake – An analysis including over 44,000 participants in 4 countries

“…Seasonality of total energy and macronutrient intake varied between countries and even between sexes. These results are in agreement with the literature, where discordant findings regarding seasonality of total energy intake and fat have been reported [1,2,4,8,9,23,24]. A study conducted in China showed no seasonality for the main nutrients and only for a selected number of micronutrients such as retinol, ascorbic acid, potassium and calcium [24].…”

A Data Entry System for Dietary Surveys Based on Visual Basic for Applications Programming

“…The DietSys system is a surrogate application developed by Sinara L. Rossato, MSc, PhD, a dietitian from Brazil, who has experienced the manual dietary data entry as part of her studies for masters and doctoral degrees. [10][11][12] The DietSys was created to facilitate incoming dietary data entry and is designed for entering intake information collected with 24-hour recall or food record methods. It also can collect nondietary information along with dietary information.…”
