BACKGROUND/OBJECTIVES: Snacking has increased globally. We examine snacking patterns and common snack foods in Brazil.
SUBJECTS/METHODS: Data from the first of two non-consecutive food diaries from 34,003 individuals (aged ≥ 10 years) in the first Brazillian nationally representative dietary survey (2008-2009) were used. Meals were defined as the largest (kcal) eating event reported during select times of the day (Breakfast, 0600-1000 hours; Lunch, 1200-1500 hours; Dinner, 1800-2100 hours); all other eating occasions were considered snacks. We estimate daily energy intake, percentage of persons consuming snacks, number of daily snacks and per capita and per consumer energy from snacks (kcal/day, kcal/snack and % of daily energy from snacks).
In all, 74% of Brazilians (≥ 10 years) snacked, reporting an average 1.6 snacks/day. Also, 23% of the sample were heavy snackers (≥ 3 snacks/day). Snacking accounted for 21% of daily energy intake in the full sample but 35.5% among heavy snackers. Compared with non-snackers (1548 kcal/day), light (1-2 snacks/day) and heavy snackers consumed more daily energy (1929 and 2334 kcal/day, respectively). Taking into account time of day, the largest percentage of persons reported afternoon/early evening snacking (1501-1759 hours, 47.7%). Sweetened coffee and tea, sweets and desserts, fruit, sugar-sweetened beverages, and high-calorie salgados (fried/baked dough with meat/cheese/vegetable) were the top five most commonly consumed snacks. Differences were observed by age groups. Trends in commercial sales were observed, especially for sugar-sweetened beverages.
Many commonly consumed snack foods in Brazil are classified, in the US, as being high in solid fats and added sugars. The public health impact of snacking in Brazil requires further exploration.
背景/目的:零食消费在全球范围内呈上升趋势。本研究旨在调查巴西的零食消费模式和常见零食。
研究数据来自巴西首次全国性饮食调查(2008-2009 年)中 34003 名(年龄≥10 岁)个体的第一份非连续两份饮食日记。用餐时间定义为一天中特定时间(早餐:06:00-10:00;午餐:12:00-15:00;晚餐:18:00-21:00)报告的最大(千卡)进食事件;其他所有进食场合均视为零食。我们估计了每日能量摄入量、食用零食的人数百分比、每日零食次数以及人均和消费者零食的能量(千卡/天、千卡/零食和零食占日能量的百分比)。
巴西共有 74%(≥10 岁)的人吃零食,平均每天吃 1.6 份零食。此外,23%的样本为重度零食消费者(≥3 份/天)。零食占总样本日能量摄入量的 21%,但在重度零食消费者中占 35.5%。与非零食消费者(1548 千卡/天)相比,轻度(1-2 份/天)和重度零食消费者摄入更多的日能量(1929 和 2334 千卡/天)。考虑到一天中的时间,报告下午/傍晚吃零食的人数比例最大(1501-1759 小时,47.7%)。加糖咖啡和茶、糖果和甜点、水果、含糖饮料和高热量的 salgados(油炸/烘焙面团配肉/奶酪/蔬菜)是最常食用的前五名零食。不同年龄组之间存在差异。观察到了商业销售的趋势,特别是含糖饮料。
巴西常吃的许多零食在美国被归类为高固体脂肪和添加糖。需要进一步探索巴西零食消费对公共健康的影响。
