Zinc and copper in infant diets.
Journal of the American Dietetic Association
|September 1, 1983
Summary
This study assessed infant nutrition in Utah, finding adequate zinc and copper intake among 59 healthy infants. Copper was identified as the limiting nutrient, with zinc-to-copper ratios slightly above recommendations.
Area of Science:
- Pediatric Nutrition
- Human Health and Nutrition
- Dietary Analysis
Background:
- Infant nutrition is crucial for healthy development.
- Assessing micronutrient adequacy in infant diets is essential.
- Previous data on zinc and copper intake in infant diets may be limited.
Purpose of the Study:
- To evaluate the nutritional adequacy of diets for healthy Utah infants.
- To determine zinc and copper intake levels in this population.
- To assess the zinc-to-copper ratio in infant diets.
Main Methods:
- Analysis of dietary intake in 59 healthy Utah infants.
- New assays for zinc and copper content in commercial baby foods and table foods.
- Calculation of zinc and copper intake based on food consumption.
Main Results:
- Group averages indicated adequate overall dietary intake.
- Copper was identified as the limiting nutrient in the analyzed diets.
- Zinc-to-copper ratios were found to be slightly higher than suggested levels.
Conclusions:
- The diets of healthy Utah infants generally provide adequate nutrition.
- Attention to copper intake may be warranted.
- Current zinc-to-copper ratios are marginally elevated but likely not a cause for concern.

01:26EDTA: Auxiliary Complexing Reagents
EDTA titrations are usually carried out in highly basic conditions, where the fully deprotonated form of EDTA, Y4−, actively complexes with the free metal ions in the solution. Several metal ions precipitate as hydrous oxide (hydroxides, oxides, or oxyhydroxides) under these conditions, lowering the concentration of free metal ions in the solution. For this reason, auxiliary complexing agents or ligands such as ammonia, tartrate, citrate, or triethanolamine are used in EDTA titrations to...
01:17Precipitation and Co-precipitation
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...
00:56Extraction: Advanced Methods
Metal ions can be separated from one another by complexation with organic ligands–the chelating agent– to form uncharged chelates. Here, the chelating agent must contain hydrophobic groups and behave as a weak acid, losing a proton to bind with the metal. Since most organic ligands used in this process are insoluble or undergo oxidation in the aqueous phase, the chelating agent is initially added to the organic phase and extracted into the aqueous phase. The metal-ligand complex is formed in...
01:22Development of Immunocompetence
The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.

01:26Minerals
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.
01:28Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
