The food industry is the point of final integration of consumer food choices with dietary guidelines. For more than 40 years, nutrition recommendations emphasized reducing dietary intake of animal fats, cholesterol, and protein and increasing intake of cereal grains. The food industry responded by creating a convenient, low cost and diverse food supply that featured fat-free cookies, cholesterol-free margarines, and spaghetti with artificial meat sauce. However, research focused on obesity, aging, and Metabolic Syndrome has demonstrated merits of increased dietary protein and reduced amounts of carbohydrates. Dietary guidelines have changed from a conceptual framework of a daily balance of food groups represented as building blocks in a pyramid designed to encourage consumers to avoid fat, to a plate design that creates a meal approach to nutrition and highlights protein and vegetables and minimizes grain carbohydrates. Coincident with the changing dietary guidelines, consumers are placing higher priority on foods for health and seeking foods with more protein, less sugars and minimal processing that are fresh, natural, and with fewer added ingredients. Individual food companies must adapt to changing nutrition knowledge, dietary guidelines, and consumer priorities. The impact on the food industry will be specific to each company based on their products, culture and capacity to adapt.
食品行业是消费者食品选择与膳食指南最终整合的关键环节。四十多年来,营养建议一直强调减少动物脂肪、胆固醇和蛋白质的膳食摄入量,并增加谷物的摄入量。食品行业的应对措施是创建了一种方便、低成本且多样化的食品供应体系,其特点包括无脂饼干、无胆固醇人造黄油以及配有仿肉酱的意大利面。然而,针对肥胖、衰老和代谢综合征的研究表明,增加膳食蛋白质摄入量和减少碳水化合物摄入量具有诸多益处。膳食指南已从一个以食物组每日平衡为概念框架(以金字塔中的积木形式呈现,旨在鼓励消费者避免摄入脂肪),转变为一种餐盘设计,这种设计采用了一种膳食营养方法,突出了蛋白质和蔬菜,并尽量减少谷物碳水化合物的摄入。与不断变化的膳食指南相一致的是,消费者更加注重健康食品,追求富含更多蛋白质、低糖且加工最少的新鲜、天然且添加成分较少的食品。各个食品公司必须适应不断变化的营养知识、膳食指南以及消费者的优先选择。对食品行业的影响将因各公司的产品、文化和适应能力而异。
