大多数美国成年人摄入过多的, 主要来自家庭以外的食物. 减少商业加工食品中的是降低摄入量和改善公共健康的关键.
科学领域:
- 营养科学
- 公共卫生
- 饮食摄入量分析
背景情况:
- 在美国成年人中, 的消耗过多很普遍.
- 了解饮食中的来源对于有效的减肥策略至关重要.
研究的目的:
- 确定美国成年人饮食摄入的主要来源.
- 为减少的公共卫生倡议和饮食指南提供信息.
主要方法:
- 在三个不同的大都市地区招募450名成年人 (伯明翰,阿拉斯加州;帕洛阿尔托,加州;明尼阿波利斯-圣保罗,密尼苏达州).
- 每位参与者收集四个24小时的饮食回忆,包括添加盐的重复样本.
- 包括多种种族/族群以及性别均衡的代表性.
主要成果:
- 在家庭以外的食物中添加的是主要来源,占总摄入量的70.9%.
- 这一模式适用于所有人口分组,包括不同教育水平和年龄组.
- 食物中的固有 (14.2%) 和家庭制备 (5.6%) 是次要来源.
结论:
- 在家庭之外准备的食物约占饮食的70%.
- 这些研究结果支持2010年医学院的建议,以减少商业加工食品的含量.

Regulation of Sodium and Potassium
Sodium Regulation
Sodium ions make up approximately 90% of extracellular cations, with a normal blood plasma concentration of 136–148 mEq/L. A decrease in blood volume and pressure triggers the release of renin from granular cells in the juxtaglomerular complex (JGC), primarily...

Ionic Bonds
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.
