Protein in the U.S. diet
Journal of the American Dietetic Association
|March 1, 1978
Summary
Most Americans have adequate dietary protein, according to a review of nationwide studies from 1965-1975. The national food supply also provided sufficient protein, with no adverse effects noted from excessive intake.
Area of Science:
- Nutrition Science
- Public Health
- Dietary Studies
Background:
- Assessing national dietary patterns is crucial for public health.
- Understanding protein availability and adequacy informs nutritional guidelines.
- Historical dietary data provides context for current nutritional status.
Purpose of the Study:
- To evaluate the adequacy of dietary protein in the United States.
- To determine the protein level available from the national food supply.
- To investigate the effects of excessive dietary protein intake.
Main Methods:
- Review of nationwide studies conducted between 1965 and 1975.
- Analysis of dietary protein quantity and quality data.
- Examination of national food supply protein levels.
Main Results:
- Dietary protein quantity and quality were found to be adequate for most Americans.
- The national food supply provided sufficient protein resources.
- No significant adverse effects were identified from excessive protein consumption in the reviewed period.
Conclusions:
- The United States population generally met its dietary protein needs during 1965-1975.
- National food supply adequately supported protein requirements.
- Further research could explore long-term effects and changing dietary trends.
