概括
在哺乳期,母乳的矿物质含量显著变化,一些营养素含量与已确定的参考值有所不同. 这些发现凸显了基于全面的哺乳期数据更新营养指南的必要性.
科学领域:
- 人类牛奶的组成
- 营养科学
- 哺乳期研究
背景情况:
- 确定的母乳矿物质参考值可能不准确地反映整个哺乳期的度.
- 之前的研究往往缺乏在产后早期的全面数据.
研究的目的:
- 提供母乳中矿物质的参考值.
- 将这些值与医学研究所 (IOM) 确定的值进行比较.
- 根据新的参考值来分析矿物质摄入量的充足性.
主要方法:
- 在四个国家 (孟加拉国,巴西,丹麦,冈比亚) 收集了1242名营养良好妇女的母乳样本,持续了8.5个月.
- 使用感应合的等离子体质谱测量矿物质度.
- 开发了牛奶矿物质度的百分位曲线.
主要成果:
- 和的MILQ (母亲,婴儿和哺乳质量) 中位数约为IOM值的50%,而/铁约为75%,通常是由于IOM使用早期哺乳数据.
- 含量是IOM值的120%.
- 每日矿物质摄入量各不相同,和摄入量占充足摄入量的49%-55%,而铜,,和则超过了充足摄入量.
结论:
- 在哺乳期的前六个月,母乳中的矿物质度明显变化.
- MILQ数据提供了关键的参考值,突出了与IOM值的差异,特别是,和铁.
- 这些发现强调了考虑哺乳期对于准确的婴儿营养评估的重要性.

Minerals
458
Minerals are essential nutrients that the human body needs in small amounts to work properly. They play a vital role in many bodily functions, such as building strong bones and transmitting nerve impulses. Some minerals are needed for hormone production or to maintain a normal heartbeat. Major minerals include calcium, phosphorus, potassium, sulfur, sodium, chlorine, and magnesium, while trace minerals include iron, manganese, copper, iodine, zinc, cobalt, fluoride, and selenium.

Essential Minerals for Bone Health
4.4K
The minerals contained in all of the food we consume are essential for our organ systems. However, certain essential minerals, such as calcium, phosphorus, magnesium, manganese, and fluoride, largely affect bone health.
Calcium and Phosphorus
Calcium is a critical component of bones, especially in the form of calcium phosphate and calcium carbonate. Since the body cannot make calcium, it must be obtained from the diet. However, calcium cannot be absorbed from the small intestine without...
