Adult males meet zinc recommendations, while women fall short, primarily due to lower energy intake. Dietary adjustments focusing on zinc-rich foods and increased activity can improve zinc nutriture.

Area of Science:

Human Nutrition
Dietary Assessment

Background:

Zinc nutriture is influenced by food supply and individual dietary zinc content.
The U.S. food supply provides approximately 12.3 mg of zinc per person daily.
Dietary zinc intake varies between adult males and females, impacting overall nutritional status.

Purpose of the Study:

To evaluate zinc intake adequacy in adult males and females based on the Recommended Dietary Allowance (RDA).
To identify factors contributing to differences in zinc intake between sexes.
To provide dietary recommendations for improving zinc nutriture.

Main Methods:

Analysis of data from the FDA's Total Diet Study and USDA's Nationwide Food Consumption Survey.
Assessment of zinc content and energy consumption in male and female diets.

Comparison of dietary zinc intake with the 1989 Recommended Dietary Allowance (RDA).

Main Results:

Adult males consumed diets meeting or exceeding 90% of the zinc RDA.
Adult females consumed diets below 81% of the zinc RDA.
Similar zinc densities in male and female diets suggest energy consumption differences drive intake variations.

Conclusions:

Current dietary patterns can be modified to meet zinc RDA and align with health recommendations.
Encouraging consumption of zinc-rich foods like poultry, lean meats, dairy, and whole grains is crucial.
Increasing physical activity can enhance energy and zinc intake, improving overall zinc status.
