Russ Altman: 我认为美国有很多人因为资源不足而无法健康饮食,这导致他们面临更高的疾病风险和医疗成本。大约14%的家庭没有足够的资源购买健康食物,导致他们选择高盐、高脂肪、低纤维的不健康食品,从而增加患心血管疾病、糖尿病、癌症甚至精神健康障碍的风险。 Lisa Goldman Rosas: 食物不安全指的是无法获得维持健康生活所需的食物,它不仅与食物的数量有关,还与食物的质量有关。我们现在更倾向于使用“营养安全”这个概念,它在食物不安全的基础上,增加了预防和管理慢性疾病的成分。当家庭被归类为食物不安全时,他们通常会选择最便宜的卡路里,而这些卡路里往往是不健康的。此外,食物不安全家庭往往没有足够的时间将健康食品变成膳食。

Chapters
Food insecurity is more than just hunger; it's about lacking access to nutritious food for a healthy life. This leads to health issues and is increasingly understood as nutrition security, encompassing disease prevention, management, and treatment. The lack of access to healthy food disproportionately affects certain households in the US.
  • Food insecurity affects approximately 14% of US households.
  • It's linked to increased risks of cardiovascular disease, diabetes, certain cancers, and mental health disorders.
  • Nutrition security is a newer concept that emphasizes the health value of food beyond just calories.
