Reductions in muscle mass and strength are well known complications of advancing age. All muscles of the body are affected, including those critical to chewing and swallowing. A diagnosis of frailty and its features of weakness and unintentional weight loss are particularly relevant to the aging swallowing system. Age related changes to eating and swallowing function means that there is a natural tendency for elders to self-select 'soft' foods due to loss of dentition and fatigue on chewing. However, it is not well known that tooth loss and poor dental status is associated with increased choking risk, especially as people age. In fact, people over 65 years of age have seven times higher risk for choking on food than children aged 1-4 years of age. Texture modified foods are provided clinically to reduce choking risk and manage dysphagia. Although certain food textures offer greater swallowing safety, they significantly restrict food choice. This commentary paper will highlight age-related changes to the eating and swallowing system, noting especially those that are relevant for frail elders. Swallowing impairments also affect the ability to manage liquids, and aspiration risk in healthy and frail elders is also discussed. Modified food textures that are most often recommended by clinicians to maintain sufficient oral intake and reduce choking risk will be described, while also highlighting the nutritional challenges associated with these foods and offering some solutions. The ethical challenges associated with balancing the autonomy of choice of food textures with swallowing safety will be addressed.
肌肉质量和力量的下降是衰老过程中众所周知的并发症。身体的所有肌肉都会受到影响,包括对咀嚼和吞咽至关重要的肌肉。衰弱的诊断及其虚弱和非故意体重减轻的特征与衰老的吞咽系统特别相关。与年龄相关的饮食和吞咽功能变化意味着,由于牙齿缺失和咀嚼疲劳,老年人自然倾向于自行选择“软”食物。然而,牙齿脱落和口腔状况不佳与噎食风险增加有关,尤其是随着年龄增长,这一点并不为人熟知。事实上,65岁以上的人食物噎食风险比1至4岁的儿童高7倍。临床上提供质地改良的食物以降低噎食风险并管理吞咽困难。虽然某些食物质地提供了更高的吞咽安全性,但它们显著限制了食物选择。这篇评论文章将重点介绍与饮食和吞咽系统相关的年龄变化,尤其指出那些与体弱老年人相关的变化。吞咽障碍也会影响处理液体的能力,同时还将讨论健康和体弱老年人的误吸风险。将描述临床医生最常推荐的改良食物质地,以维持足够的经口摄入量并降低噎食风险,同时强调与这些食物相关的营养挑战并提供一些解决方案。还将探讨在食物质地选择自主权与吞咽安全之间取得平衡所涉及的伦理挑战。
